More and more laser engraved silicone keys are installed on a variety of machines, spray laser engraving technology silicone products of many forms, some of the lasers engraved silicone keys can not leak light, how should we prevent it?

First of all, the main forms of producing radium-engraved silicone keys are as follows:

1. Directly transparent silicone surface will be printed characters by screenprinting so that the whole key is transparent,

2. Directly print hollow characters on the surface of transparent membrane keypad. This keypad membrane is similar to the above one in terms of light transmission, but its side is also transparent;

3. Choice of transparent color silicone. We will print oil on the surface, such as grey oil, red oil, black oil, etc., and then paint the oil layer with radium to carve out the characters so that only the characters are transparent and the product side is opaque. Method 3 is the best choice to make this kind of product.

Usually, we would advise the customer to choose the third way, but there is a problem of light leakage in this way, how to solve the problem of light leakage? Consider the following approaches:

1. The most direct method is to print the ink to be thicker;

2. Before printing the last layer of ink, apply a layer of base oil, which is used to block light and prevent light leakage;

3. If the distance between the two silicone keys is too small, the structure will affect the effect of oil injection shading, then you can only use the way of oil coating, before the last layer of ink spraying, and can not spray the location of a layer of ink shading, but the cost of this way is the most difficult to control, it is not recommended that customers choose this way.

No matter spray is thick, add a layer of bottom oil or the way of oil. We need to consider not affecting the radium carving process. Because the oil layer is too thick, it is possible that the radium vulture will not remove the oil clearly. The niceone-tech factory is a membrane keypad manufacturer specializing in customized silicone rubber keypad products. All processes, including molding, screen printing, spraying, glue dropping, and assembly, are independently completed in the factory and provided online by engineering

How to Customize a Perfect Membrane Switch?(2024年02月01日)

niceone-tech — 2024-01-30T11:44:38+0900

https://www.niceone-tech.com/how-to-customize-a-perfect-membrane-switch.html

Many industries in all walks of life have adopted membrane switch. The main reason is the reliable performance of the membrane switch and the very independent custom design.

How to customize a membrane keypad connector that belongs to you needs to remember some things. Membrane switch use environment and conditions, some potential problems that may exist in the manufacturing process, cost and aesthetic issues, etc. This series of problems need to be customized and solved by the customer and the supplier.

When the customer informs the use of Niceone-tech products in detail, then Niceone-tech will select the appropriate materials according to the use, the appropriate design will solve potential problems, reduce costs, and improve aesthetics.

Common designs are:
Membrane switch connector options:
Membrane switch is connected with the PCB board of the machine or equipment board by the conductive part of the wire. There are generally three types of conductive parts of the lead wires: ZIF, Female connector or Male Conncetor, and even PCB pin headers: Most Membrane switches have very flexible circuits, and the conductive area on the circuit can be connected to the PCB connector through different bends. through. Sometimes it is even necessary to be soldered on the printed circuit board by means of thermal fusion of the connector. But this type of connection is gradually being eliminated.

The distance between the pins of the PET membrane switch leads is 1mm, 1.27mm and 2.54mm.

The distance between the PINs of the FPC membrane switch leads are 0.5mm, 1mm, 1.27mm and 2.54mm.

The thickness of the stiffener required at the end of the ZIF line is usually 0.3mm. The distance between ZIF's PINs is 0.05-1.27mm. The maximum distance between connectors with male or female connectors is 1.27-2.54mm.

What needs to be considered in the customization of Membrane switch?

The previous article said that one of the advantages of a Membrane switch is an independent design, which can meet customer needs by changing different structures and designs. So we are very happy to work with customers to design membrane switches, what should we consider?

1. Waterproof performance-the IP rating that the membrane switch needs to meet, NEMA4, etc., usually the membrane switch can reach IP65. If you need IP68, you need to send data to Niceone-tech to analyze whether it is feasible.

2. Cost considerations-how to control costs under the premise of ensuring quality. If the number of products is particularly large, there are several ways to save costs-

A. Use a silicone rubber keypad as the panel.

B. Screen printing is changed to color printing. When customers can accept the color difference of digital printing, the cost of color printing can be reduced by 3-5% relative to screen printing.

C. The product does not need too long life. Sometimes the product is a one-time or temporary product, then we can use cheaper PC materials as the panel.

D. Use Nondome membrane switch to reduce the cost of a metal dome.

Although there are many ways to reduce costs, the prerequisite is to ensure customer quality.

3. Noise problem-when the product is in a recording studio or a product that cannot make membrane switch sound, we need to choose Non-tactile membrane switch.

4. Backlight option-if the product is used in the dark or in a place with low light, then the backlight membrane switch needs to adopt the backlight technology. Can also be the "star" in the night.

5. The circuit is small in size and requires more electrical functions: FPC and printed circuit boards are very good choices as membrane switch circuits. At the same time, the circuit can be used in a high-pressure and high-humidity environment without silver migration.

6. Outdoor use-The biggest problem outdoors is humid weather or ultraviolet rays. Need to choose anti-ultraviolet material or waterproof structure.

It also needs accurate tactile feedback and the Membrane switch has two forms to meet this requirement.

1. There are shrapnel in the Membrane switch, the driving force is generally between 150-600G, and the life span is 100,000 to 1,000,000 times.

2. The Graphic overlay is embossed by hot pressing and hardware molds to obtain better tactile feedback. The interior does not contain shrapnel, and more often it requires silver dots.

Is there any difference in the material selection of the Membrane switch?

Most membrane switch panels made by Niceone-tech use polyester instead of polycarbonate. Although polycarbonate is more economical than polyester, its practicality is far less than polyester. Niceone-tech did an experiment. After 1,000,000 cycles, the panel made by polyester showed no signs of wear, but the polycarbonate was damaged after 100,000 cycles. Polyester is more resistant to corrosion. If you need to know more about the difference between these materials, you can click membrane switch design guide to get a more detailed understanding

Does the product need a shielding layer?

Customers sometimes ask that the third layer of the membrane switch sometimes sees silver oil grid, PI, or ITO coating. What are the functions of these? As more and more devices can use plastic casings instead of traditional metal products, the main reason is that plastic casings are very portable and flexible in design, and the price is also affordable.

Although plastic products have many advantages, they also have obvious shortcomings: they cannot completely resist the interference of ESD, RFI, and EMC, which causes electronic failure of the equipment. However, such problems can be solved by combining methods such as printing silver oil grid, PI or ITO coating with membrane switch.

When we need to shield ESD, RFI and EMC, we need electrostatic shielding layer

What will the metal dome in the membrane switch affect?

1. Although the Metal dome is an inconspicuous component of the membrane switch and metal dome switch, it is a very important component. It is one of the key points of whether a membrane switch can become a perfect membrane switch.

2. Load: A load of different metal domes is different. According to the structure of the product, select the most suitable shrapnel, generally between 280-350G.

3. Size: metal dome between 8.4-12.2 is very commonly used and the hand feel is also a relatively good range

4. The difference between different coatings: most of the time the membrane switch will use the conventional stainless steel metal dome. But when the product is used in products with very sensitive electrical properties and low resistance, nickel-plated or gold-plated shrapnel should be considered.

5. Whether the product should be rectangular or round: choose according to the specific situation of the product.

6. Life requirements: the smaller the size of the shrapnel, the greater the load, and the lower the life. So the shrapnel in the 8.4-12.2mm range is more selected by Niceone-tech. Longer life.

When Niceone-tech knows more, we can help you design better products. A good China Membrane switch requires the efforts of suppliers and customers. Niceone-tech has always been committed to developing the most suitable and perfect membrane switch for customers, because we treat each product very carefully.

How to Clean the Silicone Rubber Keypad?(2024年02月01日)

niceone-tech — 2024-01-30T11:44:03+0900

https://www.niceone-tech.com/how-to-clean-the-silicone-rubber-keypad.html

Silicone rubber button keypad has good chemical stability, is non-toxic and tasteless, insoluble in water and any solvent, acid, and alkali corrosion resistance, heat resistance, scratch resistance, and other advantages, so it has been widely used in daily life. Products are also susceptible to dust and bacteria over time. If it is not cleaned regularly, it may even affect the circuit equipment. Silicone keys dirty will affect the appearance.

How to clean silicone keyboard cover is also an important issue:

Take the silicone button apart first and soak it in clean water;

If there is a lot of dirt on the silicone rubber keypads, you could gently scrub them with a soft brush and toothpaste;

Rinse off the foam with water after cleaning the silicone rubber keys, and then wipe the silicone rubber keys clean;

Step 1. Clean rubber button keypad with alcohol disinfection, but we couldn't use too much alcohol. The main reason is the silicon rubber will become yellow after using too much alcohol. Step 2. Use a hairdryer to dry the silicon rubber keys at a normal temperature. Step 3 Hang up in the room and not be put in the sun to dry. The silicone rubber keyboard dry quickly. At the same time, if the silicone can't be peeled off the circuit, then we recommend using cleaning silicone with alcohol instead of water. Because the alcohol is volatile, it doesn't damage the circuit.

If the dust is minor and not affect the circuit, we could use the Feather Duster to clean the surface of the silicone rubber keyboard. It is a safe and effective way to clean silicone rubber keypad with Feather Duster.

How Does the Silicone Rubber Keypad Manufactured by Niceone-tech Make Your Electronic Products More Profitable?(2024年02月01日)

niceone-tech — 2024-01-30T11:43:31+0900

https://www.niceone-tech.com/how-does-the-silicone-rubber-keypad-manufactured-by-niceonetech-make-your-electronic-products-more-profitable.html

The product with the most complete functions and the best performance in the market is often not necessarily the best-selling product, because it will inevitably be restricted by factors such as price and customer awareness. How to make your products sell well? You need to reduce or maintain the price, while allowing you to increase the profit of your electronic products. The methods are (1) Maintain the product's functions unchanged or eliminate unnecessary functions to reduce costs. (2) When the target cost is fixed, increase the added value of the product. (3) Reduce your product development and testing costs.

How to keep the function of Silicone rubber keypad unchanged or eliminate unnecessary functions to reduce costs:
1. Don't pay too much attention to product performance and ignore product economy (cost):
Eliminate functions that can not bring market value but increase cost: The basic requirement is to retain the silicone rubber keypad function in electronic products in accordance with the market needs. The cost of redundant functions. For example, the customer's silicone rubber keypad does not need to be used in an ultraviolet environment, but uses anti-ultraviolet raw materials. Even if your product comes with this function, it will invisibly increase the cost. If the market and users feel that the anti-ultraviolet function is redundant, then the market and users will not pay extra for this feature.

2. Can't pay attention to the surface cost and ignore the hidden (sunk) cost:
The bottom of the membrane keypad often contacts the Metal dome to form a complete circuit function. Some companies feel that it is possible to independently mount and assemble the Metal dome on the PCB circuit or FPC circuit. After attaching the Silicone rubber keypad, the cost on the surface is indeed lower than the price of a complete Silicone rubber keypad with a Metal dome layer, but it is ignored. The assembly cost of the product and the labor cost of installing the shrapnel will be even higher.

3. Increase product awareness and reduce costs:
For example: Silicone rubber keypad can sometimes be assembled with a silver membrane switch panel, but the use of Flex copper circuit or PCB as the circuit invisibly increases the cost. When Flex copper circuit or PCB is used as the circuit, in many cases the circuit cannot meet the function of electrical products, but the Silver membrane switch can be used with jumpers to meet the function. What kind of line to use is important to the knowledge of the product, rather than simply picking the most expensive product to solve the problem and increasing the cost.

Niceone-tech provides our assistance in these three areas: 1. The engineering team and the marketing team help customers analyze existing samples, or new samples eliminate functions that can not bring market value but increase costs. 2. The engineering team and production team will help customers analyze sunk costs and focus on overall costs. 3. Due to the high experience of the engineering team, we will give our reference opinions and production guidance to customers. After maintaining unchanged functions or eliminating unnecessary functions, reduce customer costs.

Increase product durability and practicability as much as possible without increasing the target cost, so as to increase market reputation and obtain follow-up orders.
1. It can provide products assembled with a Silicone rubber keypad and Metal dome to reduce customer labor costs: After the Silicone rubber keypad and Metal dome tape are assembled, customers or users can reduce labor costs to install shrapnel and tape. Compared with the European and American markets with relatively high labor costs, the Chinese market has lower labor costs. Reduce product labor costs.

2. By Adding up color material: you can make the buttons form different colors to enhance the aesthetics.

3. Use PU oil to protect the key ink of the Silicone rubber keypad to enhance its wear resistance.

A. Spraying PU can make the product printing not easy to peel off. Even with long-term friction and contact, the ink above the silicone rubber keypad will not be too damaged.

B. After the product is completed, a wear resistance test is required.

4. Use laser carving to make button characters and patterns:：make the product adds a backlight function.

Increase product durability and practicability as much as possible without increasing the target cost, thereby enhancing market competitiveness. This series of operations is not difficult for Niceone-tech's factory which specializes in manufacturing rubber membrane switch, and can even give you a price that is unexpected.

Reduce your product development, proofing and testing costs：
1. Strengthen the cost analysis of new product development to achieve the best combination of cost and performance:
Niceone-tech's engineering team strengthened the analysis of the performance-to-cost ratio of Silicone rubber keypads: performance-to-cost ratio is the ratio between the target performance and the target cost. Through the analysis of this index, it can be seen whether the newly developed Silicone rubber keypad meets the requirements. The originally set target cost, target function and target performance and other related targets. If the actual cost-performance ratio of Silicone rubber keypad is higher than the target cost-performance ratio, under the premise that the design cost is consistent with the target cost, it means that the performance of the new product design is higher than the target performance, but on the other hand, we can still Reduce and cut costs by adjusting the performance of the new product to match the target performance. Consider the cost of expansion: When developing and designing a new product, in addition to the material cost, it is necessary to further consider whether the application of the material will increase the cost in other aspects. For example, whether the materials used are easy to purchase, easy to store, assemble, and ship. In fact, when designing a new product, if the R&D (designer) personnel lack comprehensive consideration, they often have to temporarily add some materials or increase the difficulty of the assembly during the rectification process to solve some of its defects. And these temporarily increased materials will not only increase the material cost, but also increase the assembly complexity in the production process, which indirectly affects the efficiency of mass production, and it is also likely to cause a substantial increase in the consumption of related materials, auxiliary materials, etc. These sunk costs are often far greater than their apparent costs.

2. Reduce the number of times the design needs to be modified before it is delivered to production:
The number of times the design needs to be modified (even minor modifications) before it is delivered to production (normal mass production). This is an indicator for calculating the development cost of a new product. Many facts show that it often takes a long time for a new product to be put into the market in batches. The biggest reason is that the product cannot meet the design requirements at one time and usually needs to be redesigned and retested several times. Assuming that a company estimates that the cost of each design error is 500 USD if each new product needs to be modified on average 5 times before the new product is developed and designed for production, and 15 new projects are introduced and developed each year, the error cost is 37500 USD. From this simple arithmetic, we can see that in the process of delivering normal mass production, every error (every modification) is bound to bring certain losses to the company (materials, labor, waste of efficiency, etc.). The time delay in redesigning products to reduce errors will cause products to enter the market later, and the lost sales due to missed opportunities are even more distressing. Therefore, the development and design of R&D designers should maximize the success rate of a design without affecting the cost and performance.

3. Test cost reduction:
Test cost including life test, color test, wear resistance test and tactile feedback test are all relatively high costs. Can successfully reduce such costs, then the price will be competitive in the market for customers. Therefore, Niceone-tech purchases a large number of test instruments to reduce customer production costs.

As a pro membrane keyboard manufacturer, we can deal with the above problems: (1) Strengthen the cost analysis of new product development to achieve the best combination of cost and performance. (2) Reduce the number of times that the design needs to be modified before it is delivered to production. (3) Niceone-tech has purchased a large number of test instruments to reduce customers' test costs.

I believe that with the support of the Niceone-tech team and you, we can increase the profit of your electronic products and at the same time become more competitive in the market.

Four Common Design Flaws and Improvement Schemes of Membrane Button(2024年02月01日)

niceone-tech — 2024-01-30T11:42:59+0900

https://www.niceone-tech.com/four-common-design-flaws-and-improvement-schemes-of-membrane-button.html

The long-lasting durability of Membrane Button is very important for the medical and commercial industries, otherwise the loss caused by functional failure of the device is incredible. According to the 2017 McKinsey Report, in the medical industry alone, the cost of unconventional qualified costs has increased the cost of the product by an additional $5 billion. Not only that, the lives of patients will also be damaged due to the failure of electronic equipment. Users will question the manufacturer of production equipment and lose market confidence. As a Membrane button manufacturer, Niceone-tech has found that many Membrane buttons can avoid many problems during the long-term production of Membrane buttons.

Four common design flaws:

Cross-over connections（bridged” or “jumper” connections）: Although this type of circuit design has a higher level of wiring space, silver migration often causes short-circuit problems and excessive resistance.

Improvement plan: Use Fill hole silver oil line (as shown below) Flex copper circuit or Printing Circuit Board. This can avoid the hidden dangers of silver migration and excessive resistance.

Selection of raw materials: In many cases, product failures are often caused by raw materials. Metal dome did not choose nickel plating or gold plating, resulting in too high line resistance. Using Polycarbonate as a high-frequency use of Membrane silicone keypad will cause the sheet to break, which will contaminate the product and damage its function. Not only this, but also a lot of raw materials must be selected in accordance with the actual situation.

Improvement plan: You can choose gold-plated or nickel-plated shrapnel to reduce resistance. Polyester is used as the panel material for high-frequency use.

Poorly-designed tail exit： membrane keypad Tail exit is too close to the edge. The circuit is susceptible to damp, which leads to short circuit functions of the circuit and even silver migration problems.
Improvement plan: Tail exit should be moved to the inside as much as possible, and the exit form below should be selected at the same time.

Membrane button thickness higher than enclosure: Adhesive is prone to be contaminated by moisture and chemical substances, causing adhesive and material delamination. The line will also be contaminated. It is common that double lines and material selection are wrong.
Improvement scheme: 1. Use a Flex copper circuit or Printing circuit Board to reduce the thickness of the circuit. 2. Membrane button optimizes the structure to reduce the thickness of the material.

As a leading membrane keypad manufacturer, Niceone-tech Inc believes that providing customers with a good custom membrane keypad not only allows customers to obtain more durable products, but more importantly, it reduces many hidden costs and solves potential design risks. Contact Niceone-tech, we will conduct a free risk assessment for your product within 24 hours.

Do You Want to Know How Rubber Silicone Keypads Membrane Switch Work?(2024年02月01日)

niceone-tech — 2024-01-30T11:42:25+0900

https://www.niceone-tech.com/do-you-want-to-know-how-rubber-silicone-keypads-membrane-switch-work.html

When the Switch button of the silicone membrane switch is pressed from above, the angle web will be deformed to produce the tactile feedback so that the bottom carbon dots, silver dots, and gold dots will contact the bottom PCB, PET, or FPC conductive dots. And then, the product function can be realized. When the pressure is released, the Web will recover, the conductive particles will separate from the line, and the closure will be cancelled. If the rubber membrane buttons have no conductive particles, the bottom of the rubber membrane keypad is likely to have shrapnel as the conduction point. Compared with carbon dots, silver dots and gold dots have lower resistance and are more used in medical applications.

Applications for silicone rubber keypad membrane switches:

Medical devices
Industrial equipment
Marine
Agricultural
Health & Fitness Equipment
Defense

Why is rubber popular?
Excellent physical and chemical properties: cold and hot fatigue resistance, excellent weather resistance, excellent moisture resistance, ozone resistance, antibacterial and ultraviolet radiation performance, long-term outdoor use without cracking. Super-stretch does not deform and has a strong resistance to pressure.

Price concessions: The unit price of rubber membrane buttons is lower, but the cost of molds is higher. After the mold is completed, the product delivery time is faster. Suitable for mass production

Design for silicone rubber switch:

Niceone-tech can change the Web of silicone rubber buttons, switch travel, and the hardness of silicone rubber to achieve different Tactile feedback.

Key surface treatment: The surface of silicone rubber can be changed by spraying touch oil or PU to achieve different touch feelings. At the same time, the spraying of PU and feel oil can make the button logo and font on the silicone rubber more wear-resistant and increase the service life. The method of glue application makes the button logo and font on the silicone rubber not only beautiful but also more wear-resistant

According to the application area of the product, Niceone-tech, a leading membrane keypad manufacturer selects one or more non-conductive rubber, snap dome, or conductive pellet as the conduction point according to the situation.

The custom silicone rubber membrane switch can be designed into different shapes.

Rubber membrane switch graphics can use screen printing to customize different color patterns and logos.

If different colours are needed for the same rubber membrane buttons and flow molding the color in the compression molding process is used in the silkscreen.

The backlight needs to use the form of laser engraving to form the area to be illuminated, and select the metering lamp to illuminate. Laser etching generally removes the outer coating and leaks the lighter-coloured coating below. At the same time, PU should be added to the outer coating to make the laser engraving process more beautiful.

https://www.niceone-tech.com/10-advantages-of-capacitive-membrane-switches-make-your-kitchen-equipment-more-competitive.html

Capacitive Membrane Switch often appears in the public's field of vision, such as kitchen appliances such as cooking machines at home, coffee machines from Starbucks and Coke machines from McDonald's. Why not choose a common and cheap mechanical switch and choose a Capacitive Membrane switch? Because the Capacitive Membrane Switch has excellent performance and is widely used in kitchen equipment. At the same time, Capacitive Membrane Switches will bring more benefits to users than mechanical keyboards vs membrane.

Capacitive Membrane Switch VS Mechanical Switch

Capacitive Membrane Switch has better waterproof performance
In the kitchen, it often happens that the equipment is flooded due to the accidental operation of personnel overturning the water. The good airtightness of the Capacitive membrane sheet for kitchen makes your kitchen equipment have a better waterproof effect. At this time, the adhesive tape of the capacitive membrane switch has high adhesion and airtightness that Mechanical Switch does not have.

Capacitive Membrane Switch is easier to clean
The common problems encountered in kitchen equipment are cleaning problems including oil stains, mold and salt cleaning. The flat design of the Capacitive Membrane Switch makes it very easy to clean up. The above problems can be solved perfectly by only wiping the surface several times. The Mechanical Switch is a three-dimensional button that makes cleaning difficult and easy to accumulate bacteria, oil and salt.

Capacitive Membrane Switch has a longer service life
The Capacitive Membrane Switch adopts a metal dome and embossing-free design, and the button life can be up to several million times. Usually can be used for 3-5 years. The Mechanical Switch cannot meet these requirements. Click here for high-quality metal dome switch!

Capacitive Membrane Switch makes your products more brand-effective
Capacitive Membrane Switch is a style of HMI, users can intuitively see the LOGO and brand of your product through HMI. At this time, Mechanical Switch cannot satisfy. A good brand and LOGO can bring many potential profits to a company and increase the company's competitiveness in the market.

Capacitive Membrane Switch is no noise
Compared with Mechanical Switch, Capacitive rubber membrane switch has no noise pollution. The main reason is that it has no shrapnel or bumps. Meet the user's demand for noiselessness.

Capacitive Membrane Switch has a choice of backlight form
In a dark kitchen or hall, the Capacitive Membrane Switch with backlight can make users more concentrated and less operating errors.

Capacitive Membrane Switch is smaller
Capacitive Membrane Switch is an electronic switch composed of sheet materials. Compared with the three-dimensional Mechanical Switch, the overall thickness is thinner and flat. It is well equipped with small kitchen equipment.

Capacitive Membrane Switch VS Traditional Membrane Switch

Capacitive Membrane Switch has lower cost
Since most Capacitive Membrane Switches have a four-layer structure, the material cost will be lower than that of a 6-layer Membrane Switch. At the same time, no shrapnel design can also reduce certain material costs and labor costs.

Capacitive Membrane Switch will last longer
Compared with the life of most Metal Domes of 1,000,000 times, the life of Capcitive Membrane Switch buttons without bumps can easily reach 1,000,000 times.

Capacitive Membrane Switch can be made in the form of a backlight at a lower cost
The Capacitive Membrane Switch has no Metal Dome and a flat panel design. It is easier to light up when installed with a backlight than a Membrane Switch with a Metal Dome, and the brightness is more uniform.

What Are the LEDs Membrane Switches Made Of?(2023年)

niceone-tech — 2023-07-31T15:53:48+0900

https://www.niceone-tech.com/products/waterproof-membrane-switch.html

LEDs membrane switches are very popular in the electronics industry market. You may not know what LEDs membrane switches are, but you must have seen them on treadmills, electronic remote controls and medical equipment. Perhaps the membrane switch looks very light and not so eye-catching. But its internal structure is very different. If you understand the structure of the product better, you will be more comfortable when you use this product.

Each level of LEDs membrane switch.

LEDs membrane switch can be composed of 4-8 levels.

The four-level LEDs membrane switch consists of the following integrated layers:

1. Overlay- The most common way is to use screen printing to print on 0.1-0.5mm sheets. You can usually customize text, logos and patterns.

2. Adhesive: The main function is to glue the Overlay and the bottom layer together

3. Circuit: Printed with conductive ink to arrange the electrical properties required by customers. PCB and FPC can also be used as circuits, when customers need smaller circuits or more complex circuits.

4. Adhesive: A final adhesive sheet is placed on the back of the switch to aid in the assembly of the final device.

This type of four-layer structure LEDs membrane switch does not have a metal dome. This type of structure has a lower cost and is suitable for products that consider cost effects. Since the LEDs membrane switch has LEDs inside, the height of the LEDs is about 0.3-0.8mm, so if the panel has no buttons, you can choose to increase the adhesive thickness to 0.4-0.9mm, or you can reduce the thickness of the membrane switch by embossing. If the product has a button function, then the LEDs windows must be embossed, otherwise the panel window will be broken.

The 6-level LED membrane switch consists of the following integrated layers, which is also the most common membrane switch structure.

1. Overlay: The most common way is to use screen printing to print on 0.1-0.5mm sheets. You can usually customize text, logos and patterns. Most of the time the product needs buttons and LEDs windows to emboss. The shape of the bump depends on the customer's needs.

2. Selective adhesive: The main function is to glue the overlay and the bottom layer together

3. Tactile Layer: Fix the metal dome to avoid displacement of the metal dome during use. When the product needs static electricity protection, we can also use PI or printed ESD on this layer to prevent static electricity from damaging the product.

4. Spacer: Separating the top and bottom circuit layers, the spacer is typically formed from heat-stabilized polyester in between two layers of acrylic adhesives.

5. Circuit: Printed with conductive ink to arrange the electrical properties required by customers. PCB and FPC can also be used as circuits, when customers need smaller circuits or more complex circuits.

6. Mounting Adhesive: A final adhesive sheet is placed on the back of the switch to aid in the assembly of the final device.

The 8-level LEDs membrane switch board is basically the same as the first 6 levels of the 6-level membrane switch, but the seventh is slightly different. The main reason is that metal dome and LEDs cannot be installed in the circuit at the same time, or you want to save cost without using FPC or PCB as the circuit.

7. LEDs Circuit: Assemble the LEDs on the bottom, saving the shrapnel circuit layout of the sixth layer.

8. A final adhesive sheet is placed on the back of the switch to aid in the assembly of the final device.

Additional functions and components of LEDs membrane switch:

As LEDs membrane switch can add some functions and components, the product will be more outstanding, and even the product can be used more widely.

1. Backplane: It is used as a supporting function and is an accessory of independent membrane switch. Optional materials are FR4 or metal backplane.

2. Shielding: To prevent EMI and radio frequency interference, add a layer of antistatic printing, which can be led out to ground through a lead wire or extra pin.

3. OCA: Sometimes customers need to directly attach the window to the panel instead of attaching to the surface glue. At this time, it is necessary to use OCA adhesive tape, and at the same time, vacuumize to avoid the generation of bubbles in the bonding of the window and the panel.

4. Increase the protection of Mylar to the circuit: sometimes the electronic accessories are sharp and easy to scratch the product circuit protection ink, then choose Mylar to protect the product circuit and make the product more durable.

5. Waterproof structure: By compounding the circuit structure to form a waterproof structure, the LED membrane switch can even achieve IP68 waterproof level just as a regular sealed membrane switch.

6. Epoxy: transfer the silicone rubber keypad to the membrane switch to make the product more beautiful, and at the same time increase the additional value.

High-quality LEDs membrane switches are widely used in various industries. How to choose a suitable product, then we need to understand the structure of the product, which is why Niceone-tech has integrated this information. Hope this information can help customers who need to buy LEDs membrane switch.

Features and Advantages of Capacitive Membrane Switches(2023年)

niceone-tech — 2023-07-31T15:53:13+0900

https://www.niceone-tech.com/products/membrane-keypad/

Capacitive membrane switch is a Membrane switch that switches on and changes the capacitance to operate. The realization of the function also depends on the IC to recognize the change of capacitance. Capacitive membrane switches have all the advantages of membrane switches-design flexibility, easy cleaning and good sealing.

New trends and designs of capacitive membrane switches:

As customers have higher and higher requirements for products, they even hope to extend the way the products are used.

1. Niceone-tech uses LEDs layer as the bottom line and combines capacitive membrane switches to form LEDs capacitive membrane switches. This type of product can be used in the dark.

2. Generally, the thickness of the capacitive membrane switch can be designed to be less than 1mm. The flat design is conducive to the dustproof and waterproof of the product.

3. Capacitive membrane switch products are easy to clean without embossing and are resistant to friction. Compared with conventional mechanical switches, capacitive membrane switches can do it.

4. The color printing technology can be combined with the capacitive membrane switch to form a more colorful product. More in line with the aesthetic requirements of customers.

5. It can be designed into the latest LGF capacitive membrane switch, with uniform light-emitting effect, and the thickness can be controlled below 1mm.

Material selection of capacitive membrane switch:

The panel can be made of PET materials such as AUTOTYPE and PC such as GE. Such materials are more resistant to chemical substances. The panel material can also choose antibacterial materials to resist bacteria, which is widely used in laboratories and hospitals. The panel can also be selected from materials that resist ultraviolet rays, so that the capacitive membrane switch can also be used outdoors without being easily aging.

The combination of ESD and capacitive membrane switch is used to prevent static electricity from damaging the product. Most ESD can be made by choosing transparent conductive silver oil, so that the formed ESD shielding layer can be combined with the Backlight to form a backlit membrane switch panel.

There are many choices of adhesive tape: if it is used in an environment with a waterproof level and temperature of -20-80 degrees Celsius, it is more recommended that customers use 3M and Nitto adhesive tape.

When you need to control costs-when meeting the needs of use, you can consider cost factors to choose an economical Chinese brand of adhesive tape-DT adhesive. Although the use temperature is controlled at 10-60 degrees Celsius, it is sufficient for use in a regular environment .

Some extended topics about capacitive membrane switches:

1. By choosing anti-scratch materials, the capacitive membrane switch will not be scratched or scratched even if it is used for a long time. Anti-scratch materials generally include EBG, hardened PC or hardened glass, etc., and are usually used as the panel of capacitive membrane switches.

2. When it is necessary to choose membrane switch products with a particularly long life, Niceone-tech,a trusted membrane keypad manufacturer will recommend customers use a Non-tactile membrane switch. The capacitive membrane switch also belongs to this type of product. Since there are no embossing buttons and metal dome, choose ink with stronger adhesion, which can last the product for 1-3 years.

Membrane Switch Manufacturer(2023年)

niceone-tech — 2023-07-31T15:52:37+0900

https://www.niceone-tech.com/products/silicone-rubber-keypad.html

Niceone-tech is a manufacturer of membrane switches, young but full of vitality. Our team has many years of experience in providing various types of membrane switches. We have been faced with constantly evolving electronic technology and different customer requirements. Today's electronic products are getting smaller and smaller, but their functions are getting better and better just like mobile phones. Designers and engineers combine their own professional qualities, constantly updated technology and creativity to meet different customer needs. As a professional membrane switch manufacturer, our task is to grow up with our staff to face different difficulties and overcome them to produce new membrane switches to different customers.

What are the 8 major trends of Membrane switch manufacturers?
1. The performance and functions required by Membrane switch are becoming more complex:
Customers put forward novel ideas to realize in membrane switch, but how to realize it is not impossible for a leading membrane switch manufacturer.

Membrane switch used to have only EL membrane switch and fiber optic membrane switch as the main options as the backlight membrane switch. A few years ago, a customer asked Niceone-tech whether it could replace Fiber optic membrane switch with LEDs at and lower cost. Niceone-tech developed the LGF through half a year of hard work, making the economical and fully functional led membrane switch realized.

2. Membrane switch is getting smaller and smaller, how to realize more complex functionality.
People increasingly like to use portable electronic devices, so how can Membrane switch meet the functionality of such products while reducing the size? With the improvement of electronic accessories, FPC can be used for multiple panels, and electronic components are getting smaller and smaller. Niceone-tech can sometimes make our products perfect for customers without sacrificing aesthetics and functions according to the progress of components. Demand.

3. How to resist different harsh environments
Membrane switch did not have scratch-resistant characteristics in the past, and it could not even be used outdoors because of wet or rainy conditions. With the development of technology, the current membrane switch is not only resistant to scratches, but also resistant to ultraviolet rays and waterproof.

By choosing anti-ultraviolet, hardened materials and waterproof frame structure, the product is more durable.

4. Use in low light
Decades ago, who would have thought that Membrane switch can be used in the dark, and the keys can be evenly illuminated, so that users know the location of the keys clearly. Through the selection of EL materials, Fiber Optics, LEDs or the backlight membrane switch formed by LGF, all these benefit from the advancement of science and technology, and the company's ability to integrate products with each other is becoming more and more outstanding.

5. The combination of the glue technology of the Silicone rubber keypad and the Membrane switch.
One of the more beautiful crafts in the Silicone rubber keypad is the glue craft. The liquid can also be called Resin dome. The biggest feature of the Resin dome membrane switch is that the transparent liquid above the button is very beautiful and aesthetic. With the development of the economy, more and more customers pay attention to the aesthetics of the products, so Resin dome membrane switch also came out.

6. How to expand the market
Every industry wants to expand its own market, and Niceone-tech is no exception. Our own idea is to provide customers with products with high quality, moderate prices and higher added value. With the increase of consumer electronic products in recent years, more and more customers have gradually increased their demand for Membrane switch. How the Membrane switch manufacturer can customize the functionality, visuality and added value to form a perfect membrane switch according to the needs of customers has always required the efforts of customers and manufacturers.

7. The service life of Membrane switch is getting longer and longer
There are many reasons for the failure of electronic accessories, one of which is likely to be that the life of the product has reached the end of life and lost some of its electrical functions. If the product is a military electronic device, then the failure problem is likely to cause people to lose their lives at any time. The material selection of Membrane switch has also been studied, and the life span of PET as a panel will be longer than that of PC material. If the shrapnel with suitable load can be introduced, the life of the product can be as high as 5,000,000 times.

8. Materials are becoming more environmentally friendly
Membrane switch changed from the original panel material PVC to the current polyester and polycarbonate. The use of more environmentally friendly digital printing technology also shows that people's environmental awareness is gradually increasing. In the future, we also believe that with the innovation and environmental protection of electronic components, the sustainable use and environmental protection of Membrane switch will be more improved.

Cooperating with the leading membrane switch manufacturer can obtain the most innovative and experienced team. Membrane switch can give customers more options, avoid risks, and even be at the forefront of Membrane switch technology.

What does a professional Membrane switch manufacturer need to do?
Niceone-tech always hopes to give customers recognition of our technology, and hope to become a professional Membrane switch manufacturer recognized by everyone, so we have always strictly demanded ourselves. The following are some factors that Niceone-tech believes but not limited to the following factors to become professional What the membrane switch manufacturer should do.

1. The degree of professionalism of Membrane switch- we believe that every customer wants to find a well-coordinated supplier that provides the best quality service and the most moderate price to get more orders. When we are discussing a project with a customer, we need to understand clearly the purpose, environment and cost of the product. According to customer feedback, we need to give customer feedback when quoting or drawing, not by concealing or concealing the product. Do not understand the direct production drawings and quotations. This will bring unnecessary losses to customers. And the professional understanding of Membrane switch makes us discover when drawing whether the buttons of the product are too close to the edge and cause the product to open. If we can understand that the product is used in a humid environment, we will recommend customers to use the waterproof frame quotation. Rather than blindly make products based on drawings that do not match the actual products. We hope to have more discussions with customers as partners to make the product better.

2. Treat any order equally- Niceone-tech will not discriminate or ignore because of the small quantity. We know that any order and inquiry is the trust of our customers. We hope to make every order and our customers as partners to develop this market and help our customers win more orders. There is an old saying in China called "How can you sweep the world without sweeping a house".

3. Quality control- Membrane switch is only a small electronic accessory among many electronic products, but its quality requirements are not small at all. The main reason is that Membrane switch is an HMI of electronic accessories, which can also be said to be the first impression. No scratches from the panel, ink peeling off. The manufacturer must strictly check the printing of the circuit, the resistance value of the resistance, the correct placement of the LEDs and shrapnel, etc.

4. Innovation- any electronic accessories need to keep up with the development of the times. From the beginning Membrane switch was unable to install LEDs to the current backlit membrane switch panel, it was only due to technological progress and innovation. Continuous progress and continuous innovation can be invincible in this market

5. Accurate delivery time-the basic quality of the goods also requires accurate delivery time to complete the tasks entrusted by the customer on time

What can Niceone-tech do as a Membrane switch manufacturer?
Membrane switch is a very thin electronic switch due to its open and independent design. In recent years, Niceone-tech, based on technological innovation and our own knowledge, has gradually combined backlight and membrane switch to form a backlight membrane switch. We also produce waterproof membrane switches according to customer needs.

Why is Membrane Switch One of the Best Electronic Accessories?(2023年)

niceone-tech — 2023-07-31T15:52:01+0900

https://www.niceone-tech.com/products/digital-printing-membrane-switch.html

Membrane switch can be called a light touch keyboard, using sheet material, adhesive tape, LEDs, metal dome, backplane and indicator elements combined into electronic accessories. The front of the Membrane switch will display the marks, symbols, LCD window, Leds window, and buttons. It is a new type of electronic component.

Relative to mechanical switches. Membrane switch have the advantages of good waterproof, dustproof, moisture-proof, cleaned, oil-proof, corrosion-resistant, stable performance, small size, light weight, customizable, and UV resistance. Membrane switch is divided into Rigid or flex membrane switch. According to the feel, it can be divided into Tactile and Non-tactile membrane switch, according to the method of screen printing, it can be divided into digital printing membrane switch and screen printing membrane switch. No matter which kind of Membrane switch has its outstanding superior performance.

Overlay-

Polyester and Polycarbonate is usually the first choice for membrane switch keypad materials. If it is simply a panel instead of a membrane switch keypad, Lexan and Polyester are also good choices. The overlay is the most intuitive form of human-machine interface. Niceone-tech will screen print or digital print on the back of the material, and they can also be used in combination. Special requirements such as mirror silver effect are also feasible.

Overlay adhesive

As the first layer of adhesive paper under the panel, the Acrylic adhesive is usually used, generally the thickness is between 0.125-0.225mm. If it is LGF membrane switch keypad structure, the thickness sometimes reaches 0.64mm.

Top Circuit Layer (Dome retainer)

This layer usually has three functions: 1. As the Dome Retainer, it ensures that the Snap dome of the circuit layer will not form shrapnel movement due to triggering and closing, resulting in circuit failure and circuit wear. 2. Use 0.1-0.125mm Polyester printing conductive ink, carbon oil, and UV ink as the upper line. This layer structure can also be convex to make tactile feedback better. 3. Can be used as an ESD shielding layer.

Circuit Spacer (switch spacer)

Both upper and lower lines are printed with conductive ink, usually thicker tape is used to separate the upper and lower lines to avoid direct conduction of the membrane switch keypad. If the upper circuit is only used as a fixed layer, then the general thickness of the Overlay adhesive + Top Circuit Layer + Lower Circuit Layer should be greater than 0.4mm, otherwise, the panel will squeeze the shrapnel to make them feel worse. Unless the panel is convex, the four-layer structure is less than 0.4mm.

Lower Circuit Layer

The thickness of this layer circuit is usually 0.1-0.188mm. It can be printed with ink, carbon oil, and UV ink. LEDs can also be installed. Some membrane switch keypads will choose the copper flex or Printing circuit Board as the circuit. Compared with Polyester, their performance will be more stable. More often applied to the medical and military industries. If it is copper flex or Printing circuit Board as a line, Niceone-tech can even install a variety of components on the line.

Rear Adhesive

There are many choices, but the most commonly used are 3M200MP series or 3M300LSE. According to the different products of membrane switch lamination, Niceone-tech will recommend 3M300LSE if it needs higher viscosity.

Rigid Support Layer

This layer structure is generally used as the last layer of the membrane switch keypad, which can make the structure of the membrane switch keypad component more complete. Usually, the choice of materials is AL, FR4, PC, or steel. If AL is selected, nuts or feet may sometimes be added to the back of the product.

Introduction of some Membrane switch types:
Non-tactile membrane switch:

An important difference between Non-Tactile membrane switch and Tactile membrane switch is that there is no mechanical movement-when the buttons are pressed, there is no feedback response. At the same time, Non-Tactile Membrane switches are basically flat surfaces without protrusions, but they also have embossed outer edges. Non-Tactile membrane switch allows the operator to quickly locate the button. The product has no tactile feel and no metal dome, but it has obvious cost advantages and is easier to clean. Unlike the tactile feedback of Tactile Membrane Switch, Non-Tactile Membrane Switch feedback reflects whether the button is activated or not through the color change of LEDs and the change of LCD screen content.

Tactile membrane switch

Tactile membrane switch can also be called momentary membrane switch. Tactile means has feedback. When the operator presses the switch button, the operator can clearly feel the tactile sensation given by the button and the sound from the button. This is due to the deformation of the Dome. If the pressure is removed and Dome returns to its original state, the circuit connection is interrupted.

Which material is best for your application?
The main application material of Membrane switch is Polyester or Polycarbonate. The material is mostly transparent, and different color patterns are formed on the back of the material by printing ink. Different materials have different characteristics, the main characteristics-UV resistance, chemical resistance, antibacterial, easy to clean, etc. So consider that the material needs to be selected according to your product application, and you need to choose UV resistant outdoors. The laboratory needs to be resistant to chemical substances and easy to clean. There is also a cost option, so the material panel needs to be cost-effective, then the silicone rubber keypad can also be used as a priority option.

What should be considered in the design of Membrane switch?
Waterproof performance-Marine equipment may have higher requirements for Membrane switch, which requires Membrane switch to have the characteristics of waterproof masket or reach IP67 rating.

Silver migration problem-In a high voltage and high humidity environment, Polyester's Flex silver circuit usually encounters short circuit problems caused by the migration of silver oil, so it is necessary to use a better performance Flex copper circuit.

Resistance problem-The resistance of Membrane switch is usually less than 150 ohms, but sometimes the line is too long and it is a silver flex membrane switch Then the resistance may be too large. At this time, you need to choose a gold-plated metal dome or thicken the silver oil circuit to make the resistance less than 150 ohms. A more direct method is to use Flex copper membrane switch or PCB membran switch.

Newton ring-Membrane switch adds polycarbonate as a window, there will be a gap in the middle. At the same time, Newton's rings may occur due to air transportation problems. The solution is to screen UV dots on the PC window to solve the problem.

The above are just part of the things that need to be considered when making membrane switch. If you need more detailed information, you can contact our team.

Membrane Switch Introduction(2023年)

niceone-tech — 2023-07-31T15:51:27+0900

https://www.niceone-tech.com/products/silicone-rubber-keypad.html

Membrane switch is a control system that integrates key functions, indicator components, and instrument panels. It is beautiful and light, with excellent electrical conductivity. It has the characteristics of waterproof, dustproof, antistatic interference, etc. It is widely used in electronic communications, medical equipment, industrial control, Instrumentation, automotive industry, smart home and other fields. The following is a brief introduction to the membrane switch production process.

1. Engineering Design
Several common structures of membrane switches

The membrane switch structure is divided into five structural layers: panel layer, surface adhesive layer, upper circuit, interlayer (isolation layer), lower circuit and adhesive.The panel layer is generally made of high-toughness PET or PC transparent colorless sheet with a thickness of less than 0.25mm, printed with patterns and text, and its main function is to play the role of logo and keys;The surface adhesive generally uses a strong double-sided adhesive with a thickness of 0.05-0.15mm to closely connect the panel to the upper circuit; the upper and lower circuits are both 0.125mm thick (in some cases, 0.075 and 0.1mm thickness). Excellent polyester film (PET), screen-printed conductive silver paste and conductive carbon paste, drying and aging make it have conductive properties, the connection spacing of the circuit outlet is less than 1mm, the gold finger connection socket is easy to puncture the silver paste, causing defects It is recommended that the whole circuit use FPC with strong wear resistance to eliminate bad; the interlayer is to play the role of insulation and bonding between the upper circuit and the lower circuit. Generally, a double-sided tape with a PET substrate thickness of 0.1-0.25mm is used ; The bottom layer of adhesive should first consider what kind of material it is pasted with, and choose a strong double-sided adhesive that can be closely adhered to the pasting surface. Membrane switch is a whole, all materials should consider the overall sealing, waterproof, insulation and aging resistance, outdoor membrane switch, but also to consider the wind and rain, the temperature difference between winter and summer and the strong ultraviolet radiation of the sun.

Niceone-tech's engineering personnel should consider the overall design of the membrane switch, taking into account the scientific and technological characteristics, so that the products produced are stable, reliable, economical and practical.

2. Printing
Most of the membrane switch printing is done by silk screen.The early stage of silk screen printing is printing. Before printing, use film control samples to determine whether the membrane switch film is correct and whether it is damaged. Check whether the screen is cleaned, and whether there are dirt or broken holes. Generally, the circuit uses 100T The stencils and panels are exposed with 120T stencils (especially fine ones will use 140T or 160T stencils). Then compare the sample to determine whether the film is being sun-baked or back-baked.The preparation of ink is an important work in the screen printing process, which is directly related to the appearance quality of the membrane switch. Master colorists must master color knowledge and ink-adjusting process to make the matched ink bright, bright and accurate.Theoretically, any color can be mixed with different proportions of the three primary colors (magenta, yellow, and cyan). After equal amounts of the three primary colors are mixed and mixed, they can become black (approximately). The three primary colors of ink are mixed in equal amounts and white inks of different proportions are added to form a variety of gray inks with different tones. The three primary color inks are mixed in various proportions, and can be adjusted to a variety of intermediate or multiple colors with different hue, and the hue is biased to the primary hue with a larger proportion. The two primary colors inks can be mixed into the standard intermediate colors after equal mixing. After mixing the two primary colors inks in different proportions, they can be mixed into a variety of different colors. In addition, in any color ink, the hue appears brighter after adding white ink. Conversely, after adding black ink, its hue becomes darker.

Screen printing is divided into hand printing (sample printing), semi-automatic machine printing (small batch), automatic machine printing. Before installing the screen, first check the sample to check whether the screen is correct, whether the screen film is damaged, and whether it is reversed (special attention to the circuit). During the printing process, it is necessary to repeatedly check whether the color registration position of the printed product is consistent and accurate, and whether there are paste plates, dry nets, and dust particles. Each link must be repeatedly checked whether the product is perfect and flawless, to develop a good habit of self-inspection, and pay attention to keeping the workshop and work station clean and tidy, and choose a harmonious and efficient working environment.

3. Assembly
The assembly is subdivided into punching, bubbling, shrapnel release, fitting, forming, and terminal punching.Punching is the key point for bubbling accuracy. Inaccurate hole position will cause the bubble key to not be centered, and at the same time it will be crooked during forming, resulting in defective products. The sampling position of the hole is set well. It depends on whether the vacant position is centered (the hole position offset cannot be greater than 0.05mm).The bubbling quality is closely related to the quality accuracy of the mold. If the mold key arc is too conical, the panel will not spring up after bubbling. If the mold key arc is too large, the panel will feel bad after bubbling. The height (0.3 ~ 0.5mm) is equal, and the force (160 ~ 390g force) is balanced.Membrane switches generally use nickel-plated shrapnel (guozi), when there are higher requirements for resistance stability and key sensitivity, gold-plated shrapnel (gold-plated terminals are also used in special cases). Before loading the shrapnel (guozi piece), arrange the shrapnel. Use tweezers to pick up the shrapnel and place the button on the circuit. Make sure the position is centered. For each shrapnel, use tweezers to make sure there is no double shrapnel. In the case of double shrapnel, the feel of the membrane switch will increase significantly, or even no feel.

Lamination is a concentrated embodiment of membrane switch assembly, which is to paste each structural layer of the membrane switch into a whole. First, stick the interlayer on the lower circuit, and then stick the upper circuit to the lower circuit (the elastic is embedded in the key of the interlayer, and then the elastic fixing layer is attached). Adhesive is attached to the back of the circuit; if the LED trace is a single structural layer, the light-transmitting part of the LED must be punched first, then the LED trace layer is attached, and the adhesive is attached to the back; finally the panel (the panel has (For transparent windows and lamp holes, the adhesive layer at the windows and lamp holes must be emptied). At each step of pasting, care must be taken that there are no bubbles and debris, and the colloid cannot be wrinkled (refer to the article "Assembly of Membrane Switch" for details).Stamping forming has strict requirements on the size, a small number of products can use a knife mold, the production process is irregularly checked with a caliper to check whether the size is accurate, whether the mold is deformed, it is best to have a shell test paste, and the mold should be stopped immediately. Redo the new model. A large number of products use steel molds, which have small deformation and more precise dimensions. According to the specific situation and customer requirements, the allowable tolerances of the drawings without tolerances are generally as follows:

General size (mm) Allowable tolerance (mm)

18 or less ± 0.1

18-50 ± 0.15

51-125 ± 0.2

126-250 ± 0.3

251 or more ± 0.4

The burrs and die bending dimensions of the membrane switch after stamping should not be greater than 0.2mm, and the position should be toward the side without conductors.The gold finger PIN distance is 2.54mm. Generally, the terminals of the membrane switch are equipped with black shells (there are very few requirements for 1.27mm PIN distance to hit the terminal). The terminals are divided into male and female terminals. The PIN distance is 1.27mm, 1.0mm, 0.5mm, generally do not hit the terminal, paste the reinforcement on the back of the gold finger, the reinforcement position is generally flush with the gold finger carbon paste on the back of the gold finger, according to the specified position in special cases.

4. Detection
The appearance of the membrane switch panel must not have obvious defects, such as missing strokes and different thicknesses; there are stains, light spots, deinking, stains, and scratches in the background color block; the transparent window is not clear (F150 and F200PET printing) Special attention to UV window fluid), overflow glue, residual glue, etc .no offset phenomenon (print offset offset ≤0.15mm; upper and lower key combination offset ≤0.3mm; circuit and key sheet, panel and key combination offset Position ≤0.3mm; the blank area around the back of the panel and circuit combination is offset ≤0.2mm; the bubble at the panel key and the substrate offset ≤0.5mm).The functional test requires 100% full inspection of the membrane switch, and there can be no open circuit, short circuit, poor insulation, etc .; LEDs with LED lights must not have LED leakage, and LEDs with resistance will quickly die. The membrane loop resistance value of each button of the membrane switch should not be greater than 80Ω. For loop lengths greater than 400mm and with special requirements for loop resistance, it is additionally specified on the drawing. In normal temperature and humidity environment, the insulation resistance between conductor lines is greater than 5000KΩ (500VDC for 1 minute). After high temperature and constant humidity test and salt spray test, it should be no less than 2000 KΩ.The life test requires that a single button be pressed under 2N, and the number of contact conduction should be greater than 1 million times (special requirements can be tested to 2 million times). However, check whether the surface of the button is deformed or damaged, tear the structural layer to see whether the internal structural layer of the press room is damaged, whether the key position is worn, and the life test is only a test in a relative time, without considering the actual use time span and use Changes in the environment.

High and low temperature test, stick the membrane switch to the shell, put it in the oven one week later, adjust the temperature to 60 ℃ constant temperature (± 2 ℃), after 72 hours of high temperature, take it out of the oven to cool, test the electrical performance Whether it conforms to the regulations, whether there is any change in the external dimensions, whether there is cracking and knocking. Similarly, put it in the freezer and withstand a constant temperature of -20 ℃ (± 2 ℃). After 120 hours of low temperature, remove it from the freezer and restore it to normal temperature. Wipe off the water droplets on the surface to test whether the electrical performance meets the regulations and whether the dimensions are Change, whether the glue cracks and knocks. For products requiring acid and alkali salt resistance, put the membrane switch into a solution containing 5% acid and alkali salt, and then take out the high and low temperature test to finally test whether the electrical performance and appearance meet the regulations.

5. Packing into warehouse
The key point of packaging into the warehouse is to avoid heavy pressure. To prevent multiple products from overlapping and laying flat, all are required to be erected and discharged. The box can be considered to be loaded into a small box in a small box to prevent the key from being pressed for a long time. The outlet of the membrane switch should be well protected to avoid the possibility of bending of the outlet of the membrane switch under any circumstances. At the same time, the warehouse should be protected from moisture and dust, and there is no acid, alkali or other corrosive gases in the surrounding air.

6. Key parameters

Some Questions About Silicone Rubber(2023年)

niceone-tech — 2023-07-31T15:50:52+0900

https://www.niceone-tech.com/products/membrane-keypad/

The performance and reliability of Silicone rubber products are widely used in various industries, but they will also encounter many different problems. In order to facilitate customers to understand Silicone rubber products, Niceone-tech hopes that the following content can help customers.

What effect does silicone product spray oil or PU?
Silicone rubber keypads products have a smooth, flexible surface that feels great, while others don't. The main reason is that the former spray low temperature feels oil or PU, feel oil or PU as the name suggests is to enhance the feel, Which is the silicone products using low-temperature vulcanization technology.

Benefits of low-temperature feel oil or PU spraying:
1. silicone rubber products spray low-temperature feel oil has anti-static, easy to filter, strong adhesion, good wear resistance, low baking temperature, soft and delicate feel, paint film appearance flat, uniform surface fog and other advantages.

2. The surface of the silicone rubber product sprayed with hand oil is shiny, smooth and elastic. It feels good and has a good touch on the skin.

Spray low-temperature hand oil technology：

A. First, we need to clean the surface of the silicone products and keep the surface dry.

B. Add platinum water PL6 to the ink before ink usage, stir well, and dilute it by 6-7 times with white oil; When dilution, according to the principle of less and then more, white oil is added in stages; After dilution is finished, filter it with a 300-400 mesh cloth and then apply it to the machine or spray it by hand.

C. Finally, the silica gel will be placed in a dust-free environment for 3-8 minutes after vulcanization can be carried out!
Vulcanization temperature of various rubber materials
When molding silicone rubber products, if the vulcanization temperature is increased, the vulcanization time can be shortened and the vulcanization efficiency can also be effectively improved. Therefore, many vulcanisation molding practitioners in the early stage in order to accelerate the molding speed of silicone and rubber products will start on the increase in temperature. Sometimes it does shorten the curing time, but sometimes it's self-defeating, and instead of increasing productivity, there's a whole bunch of numbness and rupture. Why does this happen?

In fact, silicone, and rubber vulcanization temperature cannot indefinitely increase, because silicone and rubber are polymers, and high temperature can cause the rubber chain output cracking reaction, and crosslink rupture, resulting in " sulfide to return the original " phenomenon, resulting in a decline in the physical and mechanical properties of the silicone, rubber products, namely, we often say change and burst. According to the experience accumulated in the production process of some silicone rubber products, Niceone-tech suggests the vulcanization temperature of commonly used silicone and rubber as follows:

Suggestions for vulcanization temperature of natural rubber (NR ): the most reasonable range: 140 ~ 150℃, the highest not exceeding 160℃;

Vulcanization temperatures of butadiene rubber (BR ) , Isoprene Rubber (IR ) and neoprene rubber (CR ) are recommended: the most reasonable range: 150 ~ 160℃, the highest not exceeding 170℃;

The vulcanization temperature of SBR and NBR is recommended: the vulcanization temperature can be over 150℃, but the highest is not more than 190℃.

The vulcanization temperature of butyl rubber (IIR ) and ethylene-propylene-diene rubber (EPDM ) is recommended: the most reasonable range is 160 ~ 180℃, the highest is not more than 200℃; Thermal vulcanization temperature of silicon rubber (SR ) and fluorine rubber (FR ) is recommended: the most reasonable range is 170 ~ 180℃.

If secondary vulcanization is needed, the secondary vulcanization temperature should be controlled at 200 ~ 230℃, and the time should be controlled within 4 ~ 24H according to the process requirements.

Summary of common quality problems of silicone products
Silicone rubber product is a kind of silicone products of silicone processing molding. Silicon rubber product has high-temperature resistance, easy cleaning, long service life, flexible, comfortable, environmental protection, non-toxic, and other characteristics, its application in our daily life is very extensive, common silicone products are silicone pacifiers, silicone tube, silicone cake mold, silicone kitchenware, silicone keys, silicone bracelet and silicone cases, but in the process of the actual use of silicone rubber products, some people will encounter all sorts of problems; Today, niceone-tech, a membrane keypad manufacturer, will introduce the causes and solutions of common quality problems in silicone products, hoping to help friends in and out of the industry.

1. Dark marks of silicone products
Causes: the moulding temperature of the silicone product exceeds the bearing range of the color paste, which will lead to water ripple after the silicone molding

Solution: control the temperature within the tolerance range of the paste

2. Silicone rubber keypad products turn yellow
Causes: When silicone products are used for a long time, the surrounding ring will turn yellow to silicone rubber keypad products;

Solution: add an anti-yellowing agent or use better silicone materials, such as food-grade silicone, liquid silicone and weather glue.

3. Silicone rubber keypad products absorb dust
Cause: Silicone rubber material contains silicone desiccants, which have a strong adsorption force on the dust in the surrounding air.

Solution: Through the production of silicone rubber keypad products in the dust-free workshop, silicone rubber keypads can reduce the contact with dust; Or the method of spraying hand oil on the surface of silicone rubber keypad products to reduce the adsorption of dust.

4. Silicone products produce oil
Causes: the mixing of silicone oil and white mineral oil in the silicone raw material leads to the conflict with white carbon black, resulting in oil production;

Solution: control the amount of silicone oil and mould release agent. Silicone oil of silica gel raw material will conflict with highly corrosive chemicals and need to use alkaline substances to increase the adhesion;

5. Moldy silicone products
Causes: some additives in silicone raw materials are the main factors leading to mildew, such as silicone oil, rubber powder, vulcanization agent, etc., they are the main nutrients to promote the growth of mold; Storage environment wet environment will promote the growth of mold silicone products;

Solution: the storage warehouse should be dry and ventilated, check whether there is any problem with the silica gel products regularly, and use alcohol or anti-mildew agent to deal with the moldy silica gel products.

6. The tension of silicone products is poor
Causes: The reason is that in order to shorten the molding time of silicone products, the membrane keypad manufacturers increase the product output by adjusting the pressure and temperature of the machine. On the one hand, a large number of defective products are likely to appear in the products, and on the other hand, the service life of the products will be shortened.

Solution: adjust the machine to suit the temperature of the molding mold of the silicone product, and extend the time of the hydraulic molding.

Due to the differences in equipment technology and experience of some silicone product manufacturers, the causes and solutions of the problems will be different. Please refer to the actual situation for details. As a powerful manufacturer with 8 years of experience in customing silicone rubber keypad, Niceone-tech has been adhering to the original intention of providing customers with high-quality products and services, providing corresponding solutions for customers' customized needs, one-stop customized services and follow-up order tracking feedback to ensure that customers can receive satisfactory goods in a timely manner.

The History Of Membrane Switch(2023年)

niceone-tech — 2023-07-31T15:49:36+0900

https://www.niceone-tech.com/products/backlit-membrane-switch/

Membrane switches have a history of 50 years from 1970 to now.

In 1970, when the first Membrane switch was officially launched, it was only improved to improve the appearance of the product. The panel was attached to the switch to form a simple Membrane switch. The product is economical but not durable and stable. Since the initial positioning of the product is to change the appearance of the product, although the appearance of the membrane switch is obviously more beautiful than the ordinary mechanical keyboard, it is a non-tactile membrane switch without any tactile feedback. Product failure often occurs. The material is conventional polycarbonate, so as users use it, the product will begin to crack and even wear. At that time, users chose more stable mechanical switches.

The situation continued until the early 1980s were improved. Membrane switch manufacturers quit the tactile membrane switch by using metal dome and The polyester material replaces Polycarbonate to solve the problem of easy damage to the product.

From 1984 to 2008, the durability of traditional membrane switches was enhanced, and mechanical switches and mechanical keyboards were gradually replaced in many industries. Adhesive and film material in Membrane switch form a complete sealing ring, making it waterproof and dustproof. At the same time, the advancement of material technology makes the membrane switch antibacterial, UV resistance and IP68 is not an illusion. The technology of silk screen has also been extended from silk screen to digital printing. Digital printing membrane switch is widely used in various industries.

Since 2008, with the continuous integration of membrane switch with other technologies, the performance of membrane switch has become more stable and outstanding. Backlight membrane switch is also available, this type of product can illuminate the button in a dark place or dark area, making It will not be affected by operation in this environment. Membrane switches have become effective human machine input interfaces (HMI) in many industries. In 2025, Membrane switch market share may reach USD 13-14 billion.

However, Niceone-tech, as a manufacturer of membrane switches, believes that this is not the end. In the future, we also believe that with the revolution of technology and materials, we can even produce membrane switches with a lifetime of 10 million cycles, which can be used in more extreme environments. The membrane switch was used.

Can Custom Graphic Overlay Meet Various Application Scenarios?(2023年)

niceone-tech — 2023-07-31T15:48:49+0900

https://www.niceone-tech.com/products/graphic-overlays.html

The Graphic overlay made by Niceone-tech can be customized according to customer needs. Even in the face of various extreme weather, outdoor use, multiple cleanings can be used continuously. Through customization, Graphic overlay can meet various application scenarios and perform well.

The factors to be considered when choosing a graphic overlay are:
Indoor or outdoor use-The difference between outdoor and indoor is that ultraviolet rays, humidity, temperature changes, etc. will extremely affect the choice of product materials. At this time, UV-resistant materials and materials that endure extreme environments will be selected based on these issues, and the cost is relatively high.

Antibacterial requirements-whether the product needs to be antibacterial, the selection of materials needs to inhibit the characteristics of bacteria, the most common example is that medical equipment most often use antibacterial materials to avoid the occurrence of medical accidents due to bacterial contamination.

Scratch resistance requirements-Graphic overlay sometimes has a large window and needs to be integrated with the LCD or touch screen. Due to long-term contact, users do not want the window to appear scratched. Therefore, the selection of materials needs to be scratch-resistant and prevent glare.

OCA fit-Graphic overlay needs to fit the PC window, and the PC and Graphic overlay need to be scratch resistant. Vacuum needs to be drawn to avoid bubbles in the product.

Cost-Effectiveness-Customers want products to be durable, sustainable in use and excellent performance, but Niceone-tech encounters some medical products that are one-time use, and it does not require high product sustainability and only pursues cost Efficiency, then we will choose more economical materials while ensuring to meet customer needs

Digital printing or Screen pringting- Both have their own characteristics. The colors produced by Digital printing can form gradient colors, and there are no too many restrictions on the superposition of colors. It is more cost-effective to choose Digital printing when the number is large. The most prominent advantage of Screen printing is that the color error is easier to control, and the price of small batch production is more economical.

Tactile feedback-The panel has good tactile feedback requirements. The embossed button formed by stainless mould will have a better feel on the panel. The convex height of the button can be 0.3-0.75mm, if possible, please see it, it can even be 3mm.

Graphic Overlay Application industry:
Fitness equipment

Medical industry

TACTILE VS. NON-TACTILE MEMBRANE SWITCHES: WHICH ONE IS BETTER?(2023年06月14日)

niceone-tech — 2023-06-14T11:12:27+0900

https://www.niceone-tech.com/tactile-vs-non-tactile-membrane-switches-which-one-is-better.html

There may be different design schemes for the same product in the electronics industry. Membrane switches in industrial products can be divided into Tactile and Non-Tactile. Which ones can be used as Tactile membrane switch or non tactile membrane switch.

Then we need to understand difference between TACTILE VS. NON-TACTILE MEMBRANE SWITCHES more deeply:
TACTILE MEMBRANE SWITCHES
Tactile membrane switch can also be called momentary membrane touch switch. Tactile means has feedback. When the operator presses the switch button, the operator can clearly feel the tactile sensation given by the button and the sound from the button. This is due to the deformation of the Dome. If the pressure is removed and Dome returns to its original state, the circuit connection is interrupted.

There are several factors that affect the Tactile membrane switch:

1. The thickness of the panel material: The thickness of the panel material of different thickness will have different effects on the feel of the product. Generally, the thicker the material, the worse the hand feel. Conversely, the thinner the material, the better the hand feel.

2. Whether the product has Embossing, Embossing height, shape, etc. Generally, embossing height of 0.3-0.5mm is the most commonly used, and the tactile feel is relatively good.

3. The force of the metal dome is an important factor that affects the membrane switch panel. The metal dome is generally placed between the graphics overlay and the bottom line. At the same time, there is a fixed layer above the metal dome to fix the metal dome to prevent the metal dome from moving. When the user hears the sound, it means that the button has been driven and the function has been implemented. The life of metal dome is generally 1,000,000 times and even part of the metal dome can reach more than 5,000,000 times without damage. Sometimes the thickness of the pattern covering layer to the circuit level of the membrane switch is too thick, we need to increase the tactile dot to increase the touch, and even punch holes above the fixed layer, add air grooves and other forms to meet customer needs.

4. The choice of mold, in the touch keypad membrane switch, there is often a small detail that is ignored by everyone, that is, the mold will actually affect the feel of the product. Generally speaking, the membrane switch produced by Stainless tooling is better than the CNC tooling membrane switch. Feel better. And this involves another type of membrane switch-Poly dome membrane switch.

NON-TACTILE MEMBRANE SWITCHES
An important difference between Non-Tactile membrane switch and Tactile membrane switch is that there is no mechanical movement-when the buttons are pressed, there is no feedback response. At the same time, Non-Tactile Membrane switches are basically flat surfaces without protrusions, but they also have embossed outer edges. Non-Tactile membrane switch allows the operator to quickly locate the button. The product has no tactile feel and no metal dome, but it has obvious cost advantages and is easier to clean. Unlike the tactile feedback of Tactile Membrane Switch, Non-Tactile Membrane Switch feedback reflects whether the button is activated or not through the color change of LEDs and the change of LCD screen content.

In any case, these two forms of membrane switch still have obvious advantages compared with traditional mechanical switches:

1. The product is thinner and smaller

2. More convenient to clean up

3. Heat-resistant, waterproof, chemical-resistant and UV-resistant (through material selection)

Silicone rubber keypad
The buttons of the silicone rubber keypad are basically high-touch products. Through the change of web, different loads are formed. Spray PU or hand-feel oil protection patterns on the surface of the keys or perform laser engraving process. There are two types of conduction: 1. The carbon pellet at the bottom of the Silicone rubber keypad contacts the PCB circuit to form conduction. 2. By using the button as a conductor, squeeze the metal dome above the PCB to form a conduction between the PCB and the shrapnel.

Repair the Non-Conductive Silicone Rubber Keypads(2023年06月14日)

niceone-tech — 2023-06-14T11:11:38+0900

https://www.niceone-tech.com/repair-the-non-conductive-silicone-rubber-keypads.html

What is membrane switch repair ?
A membrane switch is a type of electrical switch that is commonly used in electronic devices. It consists of a thin, flexible membrane that is printed with conductive circuits, which allows it to function as a switch when it is pressed. Membrane switches are used in a variety of applications, such as remote controls, medical equipment, and industrial machinery.

Membrane switch repair refers to the process of repairing a damaged or malfunctioning membrane switch. This may involve replacing the entire membrane switch assembly or repairing specific components of the switch, such as the conductive circuits or the connectors. The repairing membrane keypads process will depend on the specific problem with the membrane switch and the type of device it is used in.

It is important to have a qualified technician perform membrane switch repair to ensure that the repair is done correctly and that the switch will function properly. Attempting to repair a membrane switch without the necessary knowledge and expertise can cause further damage and may even result in injury or damage to the device.

In life, we often encounter silicone rubber keypad products, TV remote controls, industrial remote controls, and medical controllers. Products sometimes have non-conducting functions. Niceone-tech customers sometimes ask us whether they can restore their functions through some methods. Of course, some methods can be used to repair membrane keypads and make the buttons continue to be used.

1. Clean the surface of non-conductive silicone rubber keys:

Generally, it can be cleaned by means of an eraser, sandpaper, blade, and other tools. For some seriously non-conductive silicone keypad surfaces, the blade can be used to cut off part of the surface. However, this method will have a certain impact on the appearance of silicone products.

2. Membrane switch repair can be done with smeared conductive silver paste;

In case you don't know what a conductive silver paste is, this is often used in the production of membrane keypad manufacturers to repair their smudge contacts.

3. Conductive glue;

First, the non-conductive silicone keys need to be cleaned to keep the surface clean, and then the conductive glue is applied to the non-conductive area to achieve the membrane button repair.

4. The method of carbon coating to repair membrane keypads can also be used.

Need to repair the membrane keypads wash again, and then use a dry cloth to wipe, makeup, make it not conductive surface and use a pencil to daub on the surface. To note here is that pencil is a substance containing carbon elements, so using them to repair the conductive rubber membrane buttons, is relatively more than the cost of this way is economical.

Waterproof Membrane Switch(2023年06月14日)

niceone-tech — 2023-06-14T11:11:07+0900

https://www.niceone-tech.com/products/waterproof-membrane-switch.html

Common membrane switches have good water resistance, and are also very good in related oil, dust, and moisture resistance, and can be used in a variety of environments.

Waterproof backlit membrane switch: a waterproof insulating layer is coated on the surface of the conductive circuit so that the conductive circuit does not directly contact the pressure-sensitive adhesive layer, including the release paper layer and the bottom adhesive layer that are sequentially adhered from bottom to top: LED circuit layer, LED key sheet layer, button circuit layer, line key layer, fixed layer, fixed adhesive layer, LGF backlight film layer, surface key layer, panel layer, and LED between the LED circuit layer and fixed adhesive layer.

How Waterproof Membrane Switch Plays Its Role
By setting a closed side waterproof frame, and embedding the line in the side waterproof frame, and by sealing the lead-out slot of the lead wire, it can effectively prevent water and moisture from entering from the side of the product, avoiding The LED circuit and the button circuit have silver paste oxidation, which leads to the failure of product functions. In addition, no through-holes are opened within 5m / m of the upper and lower circuit surfaces from the conductive lines, and the interlayer vent holes are not in communication with the outside world.

The Advantages Of Waterproof Membrane Switches
Therefore, the insulation resistance of the conductive line due to the moisture absorption of the adhesive layer is reduced and the condition of moisture penetration into the circuit is improved. Therefore, it has the advantages of good waterproof and moisture-proof performance. The membrane switch with strong waterproof performance has the following characteristics: it is made of high-performance waterproof material so that the product can be used in 95% humid environment. No worry about rain can be used in harsh environments. If the line uses a Flex printing circuit instead of PET as a circuit, the waterproof performance of the membrane switch will be better.

Because of this, The waterproof flexible membrane switch usually has a longer service life than conventional membrane switches and can be used in more harsh environments, but the price is relatively high. It is precise because the waterproof frame and the material with high waterproof performance can make the membrane switch form a better airtight seal and protective barrier. Even on rainy days, it can still be used. If you have more questions about the waterproof frame membrane switch, please feel free to contact membrane keypad manufacturer Niceone, we can customize the membrane switch for you.

Backlight selection can shine in the dark. Because of laser carving. The product can make the button or logo appear transparent.
P+R

Precautions for custom China rubber keypads:
Snap Ratio: The Snap Ratio of the keyboard will affect the tactile feedback and product life. Generally, Niceone-tech recommends that the Snap Ratio be controlled at 40%-60%. If it is less than 40%, the life will be longer, but there is no feeling. In China, we will also call it a trip. The lower the trip, the longer the life span and the worse the tactile feedback.

Shore: The hardness is best to choose 30A-85A, if it is lower than 30A, the defective rate is higher and the product cost is more expensive. If it is higher than 85A, the silica gel is hard and easily broken.

Conventional rubber keyboard processing:Usually, PU or hand-feeling oil makes the printing life of the silicone surface longer. Epoxy treatment: The product becomes more beautiful. Conductive or non-conductive rubber keypad. Multiple color options. Phosphorescent "glow-in-the-dark" material additives. Silkscreen printed keys. Laser-etched keys. Hard coating. Epoxy coating.

Metal Dome Switch(2023年06月14日)

niceone-tech — 2023-06-14T11:10:04+0900

https://www.niceone-tech.com/products/metal-dome-switch.html

Metal shrapnel (Shrapnel for short) (because its switch is like an upside-down pot, it is commonly called Guozi slice, or 'pot slice'), also metal dome in English, made of stainless steel, is an important part of the switch.

With the help of the conductivity, the metal shrapnel acts as a high-quality switch between the user and the product. At the same time, the stable resilience of the metal shrapnel (automatically reset after pressing) is leveraged.

Materials for making snap dome and triangle or four-leg metal dome membrane switch:
The metal dome switch and snap dome switch are sure to be the switch button. If the various switches are separated from the Metal Domes, it loses its meaning, so it is said that the Metal Domes plays a key role in the switch, and it was later known as the metal dome switches and snap dome.

Application of a metal dome: used on button switches, membrane switches, tact keypads, self-locking switches, metal dome switches, and snap dome.

Function of membrane switch dome: to power on and off, which can give the operator good tactile feedback.

Originally, there is no professional name called snap dome in the early days. And a snap dome is made of metal material. Because it is a dome, it can bounce upward and be concave downward (convex and concave). Its initial state is convex upward, and it will concave downward when the operator exerts a force, and then rebounds after the force is removed. This kind of elastic metal material is uniformly called metal dome or snap dome. Later, when metal dome switches were introduced into China, many people were used to calling them metal dome switches. Metal domes also referred to as metal snap domes or tactile metal domes

Custom-made metal dome stickers of different shapes are widely used
There are four main shapes of Metal domes: triangle, circle, ellipse, and cross, with 1, 4, and 5 contacts on the top. The stickers of Metal domes should be customized according to individual needs, do not use them randomly, and avoid affecting the quality of the products. It is very convenient to assemble the stickers on the pot, and it is enough to attach a full version. Of course, pay attention to the stability of the conductive parts of the pot and the circuit board.

Metal domes are mainly in the size of 4MM, 5MM, 6MM, 7MM, 8MM, and 9MM. With a strength of 100-600gf (the strength depends on the customer's product needs), triangular pots are widely used and involve all aspects of our modern life.

The size of the pot is different. The strength can be set to large or small. If special requirements are required, special materials can be used. The strength can reach about 3000gf. The triangle has three feet and a vertex. The legs of the triangular pan can be long and endless, these are determined by the needs of customers.

Metal domes are mainly used in circuit boards, tact switches, micro switches, key switches, pc boards, and other products. It has the characteristics of stable contact, good continuity, and excellent rebound feel. The triangular pan-shaped piece is an excellent accessory used in major electronic products.

About the pot pieces:

The pot pieces can be tinned, silvered, gold-plated, and other different surface treatments. Different treatments on the surface can produce different effects. For example, tin plating can solve the problem of heating without fading. In addition, gold plating and silver plating on the surface will increase the pot pieces Gloss has a certain resistance effect.

About the pan-shaped pieces:

The pan-shaped pieces are generally made by customers with drawings provided by us. The types of pan-shaped pieces most used by the guests are round pieces and oval-shaped pieces, also known as waist-shaped pieces and cross-shaped pieces. Triangular pan slices and rectangular pan slices have diameters from 3mm to 20mm, strength from 100gf to 600gf, and special strength pans can reach 6000gf.
The back of the pan-shaped piece can be dotted or not, the round pan-shaped piece is generally five contacts, and one contact, some special needs no contact. In order to facilitate assembly, the pot pieces are generally stuck together with PET, which not only facilitates assembly but also accurately positions.

About its different names:

Metal domes are also known as metal shrapnel. Its English name is meal Dome slices. Sometimes people will say membrane switches. The name of Metal domes is generally based on his purpose. The ones commonly used in industry are called The shrapnel, and used in mobile phones, the keyboard is called the potsticker, and the switch series is called the membrane switch. Single-layer potstickers are generally full-page stickers.

Advantages: agile operation, fast assembly, disadvantages: bad experience for customers, no dustproof function, easy to be invaded by dust, and cause contact problems. Therefore, the single-layer pot-shaped pieces are becoming smaller and smaller in the market. Only when the Tiebei sealed machine does not require the protection and operation of the pot-shaped pieces, the whole-plate stickers and single-layer structured pot-shaped pieces will be used. The advantages of Double-layer film potstickers are: dustproof, durable, good feel, etc.

Disadvantages: high cost, slow assembly, etc. Double-layer membranes are widely circulated in the market, and almost all electronic products use double-layer structure pots, such as gaming keyboards, medical equipment, and even as small as remote controls. The single-layer metal dome picture below: The application of Guozi films and Guozi film stickers are becoming more and more widespread, and currently involves all aspects of life, such as the induction cooker we use for cooking, TV, air conditioning remote control, mobile phone equipment, bank U shield, cash machine, medical equipment products, various A series of buttons, touch switches, and other products are used in the pot.

Metal dome switch: the part to complete the work on the pan film switch
Metal dome is widely used. The metal dome is also the most important part to complete the work on the membrane switch. The main function of the metal dome is to contact and disconnect the power supply. Metal dome is generally made of SUS301 or 304 material. The life of the metal dome is generally over 100,000 times. The strength is determined by demand. Do not use it under too high temperature. Excessive temperature will seriously affect the service life of the metal dome.

The metal dome is used on the membrane switch to play a conductive role, conducting the two-pole contact of the membrane switch and rebounding by its own elastic force to complete the power-on and power-off functions. It is energized when the shrapnel is down and powered off when the shrapnel rebounds. Give the customer tactile feedback during the rebound process, with a certain feel (Note: proper operation, excessive back and forth movement may cause the switch to lose response).

There are many common causes of failure of shrapnel:

The operation is too frequent.
The pressure is too large, the stroke is too high.
The isolation layer is too thick.
The operation force is too small.

The effect of these reasons on the membrane switch is that if the shrapnel is forced too hard, the shrapnel cannot spring back, resulting in a continuous path, which means that the metal dome has been working.

The too-frequent operation causes the switch to malfunction and does not work for a short time. Excessive pressure will directly crush the shrapnel and keep working or not working. If it is too large, the metal dome may not be able to complete the work.

Therefore, the factors we need to consider when applying metal dome to the membrane switch are whether the metal dome can withstand the pressure of this product, whether the stroke is consistent with this product, and the isolation layer should not be too thick.

Specifications of metal keypad dome switches:

Membrane Switch and Touch Panel(2023年06月14日)

niceone-tech — 2023-06-14T11:09:25+0900

https://www.niceone-tech.com/products/membrane-switch-panel.html

Membrane panel is a type of HMI, in which the structure is generally PET, PC, PVC as the base material, DT, Nitto or 3M as the adhesive material to assemble them together. Membrane switch and panel is a kind of HMI with more prominent performance and lower prices.

The membrane touch panel is the operating system on many electronic controllers, medical accessories, agricultural products, and it is also the first interface. Color matching and design are particularly important. Fortunately, as one of the most professional membrane switch manufacturers, Niceone-tech's engineers and designers are very good at this type of membrane control panel. At the same time, we will strictly review whether the customer's drawings and ideas can be realized.

Structual of Membrane Switch And Panel
The structure of the Membrane Switch And Panel is mainly a plane three-layer or multi-layer connection group. The design of the Membrane Switch And Panel is very special. The traditional membrane switch and panel consists of graphic overlay, upper circuit, isolation layer and lower circuit. They are made on membranes of different materials. At the same time, we can glue each other with a strong pressure-sensitive glue. After that, we were coated with the covering glue. Then, the user interface for the membrane panel is determined, which also indicates that the membrane panel assembly has been completed.

Through the touch screen, we can easily judge the tactile and non-tactile membrane touch switches based on the tactile feedback. Therefore, it is very important to choose a qualified membrane switch manufacturer.

Niceone-tech Membrane Touch Control Panel Features
The membrane switch and panel are generally thin, if not specially required, the thickness is controlled between 0.7-1.2mm. If the material is too thick, Niceone-tech will advise customers to use stainless steel moulds, otherwise, the shape cannot be punched out. Even because the material is too thick, die-cut tooling cannot be used for punching.

Membrane panel:

With a sealed surface, easy to clean and affordable
Can be customized in various shapes and surfaces
Has a big application scope

In recent years, Niceone-tech is committed to researching and developing new types of custom membrane switches. LGF membrane panel not only has the life of fiber membrane panels but also cheaper than EL membrane panels. At the same time, its uniform luminescence and long life make it very popular in European and American countries.

On this basis, we have also developed a Resin dome membrane switch, the main feature is that the appearance and buttons are very beautiful. But the price will be relatively high, and the thickness will be thicker.

As one of the leading membrane switch panel manufacturers, Niceone-tech can offer custom membrane touch and control panels for various usage. We have the marine membrane switch and panel, membrane touch and control panel, etc. that can meet high-end requirements.

Niceone-tech Membrane Switch And Panel Advantages
At this time, there will be two types of printing methods to overlay the top structure of the membrane panel. Using different screen printing methods will affect cost, usability, and durability. A poor printing method will make the membrane panels coating of membrane switch overlay easy to peel off. Therefore, Niceone-tech has always been committed to quality, and we will pass the 100 grid test every time the screen printing and color printing are performed to prevent the product from peeling off the coating. Fortunately, Niceone-tech has mastered the core technology, which makes the product ink and circuit-level ink have high viscosity characteristics, and the above problems will not easily occur.

The CMYK color printing method can form gradual patterns or colors. Generally, we call this kind of digital membrane switch. The gradual color is not possible with conventional screen printing. At the same time, because color printing is very suitable for bulk goods when the quantity is large, the use of color printing will reduce the cost, but the color error of color printing will be larger. However, the general membrane switch and panel is produced by CMYK color printing. If it is a PET circuit, screen printing is still required.
Screen printing, the most commonly used printing method for membrane switch, uses ink debugging to produce a variety of colors, endowing the products with different colors. But when more colors are involved, we need more screens to create images. Meanwhile, Niceone-tech will choose different screens to produce different circuits to achieve high-precision and low-error circuits products. Screen printing is suitable for small batch production, and it also has higher color requirements and lower error rate. Even sometimes we will adopt the combination of screen printing and CMYK color printing so that a high-quality digital membrane switch with advantages of the two can be formed.

Our membrane switches are exported in large quantities to European and American countries with stable quality and affordable prices. Niceone-tech understands the standards of European and American countries, so the products are always able to meet and exceed customer expectations.

What are the functions and advantages of membrane switches?

The reason why the membrane switch keypad is widely used is because of some very superior performances. It can fulfill various requirements of users, from industrial equipment to medical equipment.

Moisture-proof performance: Because the membrane switch uses a good pressure-sensitive adhesive layer and the stable performance of Polyester, Lexan, Polycarbonate one of the materials together. Membrane switch can be designed to meet NEMA 4 and IP 67, some products can even reach IP68.

Thin: First, it is not easy to be invaded by dust, and secondly, it reduces the space of the product.

Easy to clean: Membrane switches are easier to clean the surface than other mechanical keyboards.

Cost-effective: Compared with touch keyboard and silicone rubber keyboard, membrane switch cost will be more affordable.

Graphic interface: The topmost panel of the membrane switch can be the most conventional screen printing or digital printing. Niceone-tech can design the product to achieve the best visual effect. At the same time display the company logo and key functions on the panel

Protection by design- through the design of membrane switches can achieve antibacterial, anti-ultraviolet and other effects.

Why use the membrane keypad made by Niceone-tech?
Niceone-tech can customize products that are perfect and best suited to customer requirements according to customer needs. In order to let you know how the best and most suitable membrane switch is produced, we must talk about its structure:

1. Overlay-Polyester is usually the first choice for custom membrane switch panel materials, because its life will be a little longer than Polycarbonate. If it is simply a panel instead of a membrane switch, Lexan and Polyester are also good choices. Overlay is the most intuitive form of human-machine interface. Niceone-tech will screen print or digital print on the back of the material, and they can also be used in combination. Special requirements such as mirror silver effect are also feasible.

2. Overlay adhesive-As the first layer of adhesive paper under the panel, Acrylic adhesive is usually used, generally the thickness is between 0.125-0.225mm. If it is LGF membrane switch (to LGF membrane switch) structure, the thickness sometimes reaches 0.64mm.

3. Top Circuit Layer (Dome retainer): This layer usually has three functions: 1. As the Dome Retainer, it ensures that the Snap dome of the circuit layer will not form shrapnel movement due to triggering and closing, resulting in circuit failure and circuit wear. 2. Use 0.1-0.125mm Polyester printing conductive ink, carbon oil and UV ink as the upper line. This layer structure can also be convex to make tactile feedback better. 3. Can be used as ESD shielding layer.

4. Circuit Spacer (switch spacer): Both upper and lower lines are printed with conductive ink, usually thicker tape is used to separate the upper and lower lines to avoid direct conduction of the membrane switch. If the upper circuit is only used as a fixed layer, then the general thickness of Overlay adhesive + Top Circuit Layer + Lower Circuit Layer should be greater than 0.4mm, otherwise the panel will squeeze the shrapnel to make the feel worse. Unless the panel is convex, the four-layer structure is less than 0.4mm.

5. Lower Circuit Layer: The thickness of this layer circuit is usually 0.1-0.188mm. It can be printed with ink, carbon oil and UV ink. LEDs can also be installed. Some membrane switch panels will choose copper flex or Printing circuit Board as the circuit. Compared with Polyester, their performance will be more stable. More often applied to the medical and military industries. If it is copper flex or Printing circuit Board as a line, Niceone-tech can even install a variety of components on the line.

6. Rear Adhesive: There are many choices, but the most commonly used are 3M200MP series or 3M300LSE. According to the different products of membrane switch lamination, Niceone-tech will recommend 3M300LSE if it needs higher viscosity.

7. Rigid Support Layer: This layer structure is generally used as the last layer of the membrane switch, which can make the structure of the membrane switch component more complete. Usually the choice of materials are AL, FR4, PC or steel. If AL is selected, nuts or feet may sometimes be added to the back of the product.

Electrical performance of custom membrane switches panel

What special features can Niceone-tech membrane switches provide?
Backlighting Membrane Switch with Side-LEDs
Many working environments and machines will be used in low light or dark conditions. At this time, the customer asked us if we could solve this problem. At this time we will recommend the use of membrane switches with internal lighting. Choose EL film as the light guide plate, Fiber Optics, and the newer Light guide film (LGF) structure. Niceone-tech recommends LGF, which uses side LEDs and light guide panels to make the product have lower loss and longer life relative to EL membrane switch. Also available in different colors.

The thickness of the LGF membrane switch provided by Niceone-tech can even be 0.8mm. The brightness of buttons and logos is not only uniform and long-lasting, but more importantly, we can also make them illuminate each button individually. Sometimes you can also use two-color or RGB three-color lights to enter

One step makes the product more beautiful.

If the customer wants the product to be more novel and beautiful, then we can sometimes use Epoxy in combination with the keys. Makes it an Epoxy LGF membrane switch

If you are interested in Backlit Membrane Switch, please feel free to contact Niceone-tech, we will send samples as soon as possible.

There are three other types of illuminating membrane switches below.

Fiber Optics

Fiber optic membrane switches are also a good choice for backlighting. The optical fiber material is very thin and can be used as a fixed layer of the membrane switch. At the same time, tactile feedback is better without adding a touch point. Life expectancy is up to 50,000 to 100,000 hours. The main light source is from LEDs

Through the optical fiber transmission in the membrane switch needs to light up. And can be larger than the surface-mounted LED backlight area. Click Fiber Optics membrane switch for more information.

Electroluminescent (EL)

EL backlight is driven by high frequency and low power. EL is very thin, it is a substitute for traditional lighting technology, and is widely used in various electronic accessories. The life of EL backlight products mainly depends on the driving voltage, frequency, temperature and humidity. But most EL membrane switches can reach a life of 4000 hours or more. The brightness of the EL membrane backlit switch will attenuate linearly from the initial power-on. This is also an unavoidable disadvantage relative to other backlight membrane switch panels.

The EL backlit membrane switch provided by Niceone-tech will not cause heat, electricity and EMI problems. Mainly EL is more often a "cold" lighting medium.

LEDs

A common Light Emitting Diodes membrane switch (LED membrane switch) with relatively low cost. Since this technology membrane switch cannot meet the lighting of a large area, it is mostly used for indication purposes. It is a relatively old technology. But the service life is long and deep customers love it.

Common design：

Graphic overlays digitally and/or screen printed on the backside. The effect can be customized according to your requirements including glass, metal, wood, and stone. If the panel is in a more severe environment, we can even use hardened glass and stainless steel as the panel material. It is very important to choose Overlay printing according to requirements.

The window needs raw materials to be transparent, frosted, transparent or colored. The window of the membrane switch is different, and the choice of materials is also very different. When the window is large, and it is required to clearly see the bottom LCD or touch screen. EBG series is a good choice, the material is scratch resistant. If it is just a panel, then PC or Lexan overlay is also feasible

Selective textures and UV hard-coat surface finishes

Tactile or non tactile, snap dome or non snap dome.

Pillow rim-embossed membrane switch panels

Optically clear adhesive(OCA)，Liquid Optically Clear Adhesive，Air Gap

EMI/RFI shielding

Rigid support backers such as aluminum and FR4 with PEM mounting fasteners

Standard connectors such as CJT, Nicomatic and molex, etc.

Niceone-tech's custom-designed membrane switches and membrane switch keypads. Membrane switches are used in many industries. Niceone-tech summarizes several best membrane switch industries:

1. Medical Equipment and laboratories are the major markets. Niceone-tech provides customized membrane switches with complex requirements for many European and American manufacturers. In the medical environment, based on the standard membrane keypad, the materials sometimes have antibacterial effects and easy cleaning characteristics. At the same time Niceone-tech applies backlit and glue technology to the membrane switch. It can even be produced using digital printing.

2. Industrial Controls Because industrial equipment is more demanding moisture resistance and UV resistance, so the product's waterproof requirements and UV resistance performance requirements are relatively high. The choice of materials can refer to the membrane switch design guide, I believe that the materials compiled by Niceone-tech can help you.

3. Health & Fitness Equipment Because it is often corroded by sweat, salt and moisture, the material must be resistant to corrosion. Membrane switches are often used in treadmills. Using membrane switches to optimize performance and control is very important for fitness personnel.

What is membrane switch repair?
A membrane switch is a type of electrical switch that is commonly used in electronic devices. It consists of a thin, flexible membrane that is printed with conductive circuits, which allows it to function as a switch when it is pressed. Membrane switches are used in a variety of applications, such as remote controls, medical equipment, and industrial machinery.

Keypad repair refers to the process of repairing a damaged or malfunctioning membrane switch. This may involve replacing the entire membrane switch assembly or repairing specific components of the switch, such as the conductive circuits or the connectors. The repairing membrane keypads process will depend on the specific problem with the membrane switch and the type of device it is used in.

It is important to have a qualified technician perform membrane switch and panel repair to ensure that the repair is done correctly and that the switch will function properly. Attempting to repair a membrane switch without the necessary knowledge and expertise can cause further damage and may even result in injury or damage to the device.

1. Clean the surface of non-conductive silicone rubber keys:

2. Membrane switch repair can be done with smeared conductive silver paste;

In case you don't know what a conductive silver paste is, this is often used in the production of membrane keypad manufacturers to repair their smudge contacts.

3. Conductive glue;

First, the non-conductive silicone keys need to be cleaned to keep the surface clean, and then the conductive glue is applied to the non-conductive area to achieve the membrane button repair.

4. The method of carbon coating to repair membrane keypads can also be used.

https://www.niceone-tech.com/fully-customizable-and-versatile-graphic-overlay-and-front-panel.html

Graphic front panel overlay can also be called membrane overlay or Film overlay. Graphic overlays can now be seen everywhere on the market reflecting their wide range of uses. A product can occupy the market for a long time, and such popularity cannot be separated from its superior physical and chemical properties and its economic efficiency. So Niceone-tech really wants to promote the knowledge of products like Graphic overlay.

Graphic overlay can be said to be the first impression of a product for customers and operators, and it is often the first impression of a membrane switch and panel. A fully customizable Graphic overlay is an important design challenge for every designer. Usually Dead front panel is a very common choice for designers. As the application environment of the product is different, the design scheme is also different. Fortunately, Graphic overlay can be customized to meet almost any product and industrial design.

Details as follows:

1. Different colors can be formed by silk printing or digital printing.

2. Transparent or opaque.

3. The mold can be adjusted to form Embossing.

4. It can even meet different application environments through different materials. For details, please click here.

As an engineering designer, you need to ensure that you choose the right solution to meet the needs of your customers.

Because many times the Graphic overlay is a one-layer structure or two layers. First of all, let’s talk about-how does Substrate materials affect the product?

Polycarbonate and polyester are the most common materials for Graphic overlays (because PVC is not environmentally friendly, it has gradually withdrawn from the market). The common feature of Polycarbonate and polyester is extremely high water resistance, and the resistance to debris can withstand extreme environments. If the product often needs to be used outdoors, as a Graphic overlay manufacturer, we will recommend customers to choose materials that resist ultraviolet rays-HP92W or XE's Autotype material. Specific analysis of specific situations is what a manufacturer needs to do, and it is also our mission to provide the best customer experience to customers.

The second layer is usually adhesive tape, and the most common is also 3M series adhesive tape.

What is the backlight design of the Dead front panel?

When the product is powered on, the LEDs at the bottom can illuminate its graphics, logo, or buttons. In normal times, it is a normal hidden state. Therefore, we generally use different inks to form a complete graphic overlay panel. When we design the Dead front panel, we must also consider the product's feel and whether we need to prevent glare. At the same time, the lack of correct handling and printing methods will cause the product to wear and fade. So what the designer needs to do is to understand the material, the purpose of the product, etc. Through customized design, make the product look beautiful, use and economical, and so on.

For Graphic overlay and membrane switch panels products, the design needs to consider all aspects, material selection, design ideas, and how to implement a product in an economical way. It is very important to choose an excellent graphic panel manufacturer. Contact info@niceone-tech.com to get the information you need right away.

When the Switch button of the silicone membrane switch is pressed from above, the angle web will be deformed to produce the tactile feedback so that the bottom carbon dots, silver dots, and gold dots will contact the bottom PCB, PET, or FPC conductive dots. And then, the product function can be realized. When the pressure is released, the Web will recover, the conductive particles will separate from the line, and the closure will be cancelled. If the rubber membrane buttons have no conductive particles, the bottom of the rubber keypad switch is likely to have shrapnel as the conduction point. Compared with carbon dots, silver dots and gold dots have lower resistance and are more used in medical applications.

Why is Membrane Switch One of the Best Electronic Accessories?(2022年)

niceone-tech — 2022-10-30T18:56:27+0900

https://www.niceone-tech.com/why-is-membrane-switch-one-of-the-best-electronic-accessories.html

PC membrane switch can be called a light touch keyboard, using sheet material, adhesive tape, LEDs, metal dome, backplane and indicator elements combined into electronic accessories. The front of the Membrane switch will display the marks, symbols, LCD window, Leds window, and buttons. It is a new type of electronic component.

Relative to mechanical switches. Membrane switches have the advantages of good waterproof, dustproof, moisture-proof, cleaned, oil-proof, corrosion-resistant, stable performance, small size, light weight, customizable, and UV resistance. Membrane switch is divided into Rigid or flex membrane switch. According to the feel, it can be divided into Tactile and Non-tactile membrane switch, according to the method of screen printing, it can be divided into digital printing membrane switch and screen printing membrane switch. No matter which kind of Membrane switch has its outstanding superior performance.

Top Circuit Layer (Dome retainer)

This layer usually has three functions: 1. As the Dome Retainer, it ensures that the Snap dome of the membrane keyboard circuit layer will not form shrapnel movement due to triggering and closing, resulting in circuit failure and circuit wear. 2. Use 0.1-0.125mm Polyester printing conductive ink, carbon oil, and UV ink as the upper line. This layer structure can also be convex to make tactile feedback better. 3. Can be used as an ESD shielding layer.

Introduction of some Membrane switch types:
Non-tactile membrane switch:

An important difference between Non-Tactile waterproof membrane switch and Tactile membrane switch is that there is no mechanical movement-when the buttons are pressed, there is no feedback response. At the same time, Non-Tactile Membrane switches are basically flat surfaces without protrusions, but they also have embossed outer edges. Non-Tactile membrane switch allows the operator to quickly locate the button. The product has no tactile feel and no metal dome, but it has obvious cost advantages and is easier to clean. Unlike the tactile feedback of Tactile Membrane Switch, Non-Tactile Membrane Switch feedback reflects whether the button is activated or not through the color change of LEDs and the change of LCD screen content.

Tactile membrane switch

The above are just part of the things that need to be considered when making membrane switch. If you need more detailed information, you can contact our team.

What Factors Should The Membrane Switches Manufacturers Consider When Making The Circuit Of The Membrane Switch?(2022年)

niceone-tech — 2022-10-30T18:56:03+0900

https://www.niceone-tech.com/what-factors-membrane-switches-manufacturers-consider-when-making-circuit-of-membrane-switch.html

The membrane switch circuit is the most important factor for evaluating the inherent quality of the membrane switch. The circuit should be constrained by parameters such as current, resistance, withstand voltage, insulation, and life. This is also the penetration of screen-printed products into the multifunctional and high-tech fields. Specifically, to ensure the function of the circuit.First of all, the quality of the screen printed silver paste circuit should be guaranteed and a brief description of how to make the circuit screen

Before making the electric network version, we must first consider the circuit parameters and the structural elements in the circuit to make the requirements of the screen.

(1) The metal silver contact of the membrane switches should be screen printed with a conductive carbon paste protective layer. Due to the physical properties of the carbon paste layer, the following functions can be formed: The carbon paste is a non-metallic conductor and does not combine with oxidation in the air. This protects the bottom metal silver contacts from oxidation; carbon has a small coefficient of friction and is a solid lubricant. When it acts on the switch contacts, it is helpful for rapid separation after the contacts are closed. Carbon has a higher Abrasion resistance can improve the wear resistance of the switch contacts, ensuring that the switch contacts can withstand millions of contacts. The dense carbon coating can hinder the migration of silver ions, thereby effectively protecting the electrical performance of the switch Stable, when the carbon coating acts on the lead socket, it can facilitate the insertion and extraction of the lead and the connection terminal. Because the thick carbon coating is prone to peeling off, the screen printing conductive carbon paste should not be too thick.

(2) The density of the conductive pattern: Although the thickness of the conductive pattern is the basis for laying the performance parameters of the switch. Since the circuit pattern printed by the membrane keypad switches is formed by the aggregation of particles of conductive metal (usually silver particles), printed on its In the material (silver paste), the barrier between the resin connection to the particles, the impurities to the conductor particles, and the screen mesh wire to the metal particles during the screen printing process will affect the density of the conductor pattern, thus Affect the performance of electrical parameters. For the above reasons, in order to allow conductive printing materials, especially the flake-shaped silver particles in the silver paste to pass smoothly, it is necessary to select a slightly lower mesh, and the wire diameter is required to be thinner and the hole width is relatively larger.

(3) The thickness of the conductive pattern: the resistance of the wire made of the same conductor is inversely proportional to the cross-sectional area of the wire, and the current passing through is proportional to the cross-sectional area. The thickness of the circuit pattern printed by the membrane switch is the basic condition for ensuring the performance of the switch. Therefore, in the screen making process, the thickness of the screen film must be selected to ensure that sufficient conductor circuit patterns are obtained.

(4) The smoothness of the conductive pattern: the uncleanness of the circuit pattern refers to the sharpness of the edge. It is not only for appearance considerations but more importantly, considering the impact on the electrical parameters, the unclean wires will likely make The edge impedance of the adjacent wire decreases, especially in high temperature and high humidity, it is easy to cause silver ions to extend along the edge of the wire and produce silver ion migration, resulting in short circuit between the wires and failure of the touch membrane switch keypad.

(5) The life of the conductive pattern: the conductive pattern has sufficient thickness, which not only provides favorable conditions for the passage of current and the reduction of resistance, but also improves the high wear resistance of the switch contacts in the pattern.

The History Of Membrane Switch(2022年)

niceone-tech — 2022-10-30T18:55:39+0900

https://www.niceone-tech.com/the-history-of-membrane-switch.html

What Is a Membrane Switch Keyboard

Membrane switches have a history of 50 years from 1970 to now.

In 1970, when the first membrane keyboard was officially launched, it was only improved to improve the appearance of the product. The panel was attached to the switch to form a simple Membrane switch. The product is economical but not durable and stable. Since the initial positioning of the product is to change the appearance of the product, although the appearance of the membrane switch is obviously more beautiful than the ordinary mechanical keyboard, it is a non-tactile membrane switch without any tactile feedback. Product failure often occurs. The material is conventional polycarbonate, so as users use it, the product will begin to crack and even wear. At that time, users chose more stable mechanical switches.

The situation continued until the early 1980s were improved. Membrane keypad manufacturers quit the tactile membrane switch by using metal dome and The polyester material replaces Polycarbonate to solve the problem of easy damage to the product.

Switching from Membrane to Mechanical

Since 2008, with the continuous integration of membrane switch keypad with other technologies, the performance of membrane switch has become more stable and outstanding. Backlight membrane switch is also available, this type of product can illuminate the button in a dark place or dark area, making It will not be affected by operation in this environment. Membrane switches have become effective human machine input interfaces (HMI) in many industries. In 2025, Membrane switch market share may reach USD 13-14 billion.

However, Niceone-tech, as a manufacturer of membrane switch technology, believes that this is not the end. In the future, we also believe that with the revolution of technology and materials, we can even produce membrane switches with a lifetime of 10 million cycles, which can be used in more extreme environments. The membrane switch was used.

The Beginner's Guide to Fiber Optic Backlighting(2022年)

niceone-tech — 2022-10-30T18:55:13+0900

https://www.niceone-tech.com/the-beginners-guide-to-fiber-optic-backlighting.html

Since membrane switches are gradually permeating all aspects of our lives, you must have also touch keypad membrane switch products in the form of the electronics backlighting. One possibility is an optical fiber. Optical fiber is one of the most popular backlight solutions. Widely used in membrane switches. However, since Niceone-tech purchases optical fibers like Taiwanese factories, the cost is relatively high compared to LGF and EL. The light source provided by the fiber optic backlight is very stable, requires a lower voltage, and has a longer life. So what is the composition and working principle of optical fiber?

What is fiber:
Simply put, an optical fiber is a kind of glass fiber with a small thickness. A large number of glass fibers need to be bound together to form an optical fiber film. Even so, how to distribute the optical fiber evenly and make the light spread evenly on the optical fiber requires multiple adjustments. Niceone-tech found that the optical fiber is used as a fixed layer, which can also play a role in fixing the Dome of metal dome switch.

At this time, the customer may ask, can the optical fiber emit light independently?

Niceone-tech regrets to tell customers that optical fiber cannot emit light on its own, but it can evenly distribute a large amount of light in the place where the membrane switch needs to be lit by the light generated by the LEDs. It can be said that optical fiber is a carrier of the LED light sources.

Since the cost of optical fiber backlight is so much higher than that of the EL sheet, the advantages of optical fiber are obvious:

As LED is a kind of energy-saving material, the required power is 20-50ma and life is longer. Therefore, the life of the optical fiber keypad membrane switch can reach about 30,000 hours. Compared with 3000 hours of EL sheet, the life span is more than 10 times.

The brightness is uniform.

Niceone-tech has developed the LGF membrane switch in the past few years. If the LGF structure can be used in the engineering evaluation, we highly recommend LGF because the price is lower than that of the optical fiber and the effect is the same. Only the mold cost Higher. If necessary, we can mail samples for your reference. Niceone-tec

TACTILE VS. NON-TACTILE MEMBRANE SWITCHES: WHICH ONE IS BETTER?(2022年)

niceone-tech — 2022-10-30T18:54:49+0900

https://www.niceone-tech.com/tactile-vs-non-tactile-membrane-switches-which-one-is-better.html

Then we need to understand tactile VS. non tactile membrane switch more deeply:

TACTILE MEMBRANE SWITCHES
Metal tactile switch and rubber tactile switch can also be called momentary membrane switch. Tactile means has feedback. When the operator presses the silicone tactile button, the operator can clearly feel the tactile sensation given by the button and the sound from the button. This is due to the deformation of the Dome. If the pressure is removed and Dome returns to its original state, the circuit connection is interrupted.

There are several factors that affect the Tactile backlit membrane switch:

2. Whether the product has Embossing, Embossing height, shape, etc. Generally, embossing height of 0.3-0.5mm is the most commonly used, and the tactile feel is relatively good.

In any case, these two forms of membrane switch still have obvious advantages compared with traditional mechanical switches:

1. The product is thinner and smaller

2. More convenient to clean up

3. Heat-resistant, waterproof, chemical-resistant and UV-resistant (through material selection)

As a membrane switch manufacturer, we will do our best to meet all the needs of customers.

The Specification Of The Storage And The Assembly For The Membrane keypad Switches(2022年)

niceone-tech — 2022-10-30T18:54:22+0900

https://www.niceone-tech.com/specification-of-storage-and-assembly-for-menbrane-keypad-swithches.html

Membrane keypad switches are electronic accessories. Many times when customers assemble membrane keypad switches, they will always be scrapped due to storage and placement problems. Knowing how to assemble is a very important course, so Niceone-tech is very Want to introduce the placement and storage methods to customers.

How to assemble and store membrane keypad switches?

1. There is not allow the hard scratch and the impact at the front side, and the each layers cann't be pull apart.If not,it will destory the consturction for the membrane panles and will affect the lifetime for the products.

2. Clean the enclosure where need to assemble the membrane switches, and the enclosure surface should be flat, without rust, without oil, without dust.

3. Check the position and the direction of the enclosure and tear off the bottom linner of the membrane switches.The fingers can't touch the bottom adhesive, then assemble the switches to the correction position.

4. When you assembly membrane switches with the adhesive and already tear off the bottom linner but without the assemble, the membrane switches need to be side up, and be sure the other's can't touch the rear adhesive. Also, the membrane switches already tear off the bottome linner can't be on hold for the very long time, or this will affect the adhesive funcation.

5. When assemble the switches, you need to finish the assemble by one time.When you assembly the membrane switch, you couldn't touch the membrane buttons, and the membrane switches couldn't be bend and can't reuse it. If not,it's easy to destory the switches and also will affect the funcation of the adhesive.

6. The tail cables of the custom membrane keyboard can be bent, but can't be deadened. It is easy to cause the open circuit、the bigger resistance, then affect its function.

7. The custom membrane switches need to be storage at the normal temperature, dustproof, waterproof and be sure there is no the acid gases, no the alkaline gases and no the other's corrosive gases.

8. When testing the membrane products, need to be sure the test table is hard and steady, can't press the keys dangling. When storing the switches, but sure the products are without the extra press or bend.

Waterproof Membrane Switch(2021年)

niceone-tech — 2021-10-14T12:41:17+0900

https://www.niceone-tech.com/products/waterproof-membrane-switch.html

Common membrane switches have good water resistance, and are also very good in related oil, dust, and moisture resistance, and can be used in a variety of environments.

Waterproof membrane switch: a waterproof insulating layer is coated on the surface of the conductive circuit so that the conductive circuit does not directly contact the pressure-sensitive adhesive layer, including the release paper layer and the bottom adhesive layer that are sequentially adhered from bottom to top: LED circuit layer, LED key sheet layer, button circuit layer, line key layer, fixed layer, fixed adhesive layer, LGF backlight film layer, surface key layer, panel layer, and LED between the LED circuit layer and fixed adhesive layer.

How Waterproof Flexible Membrane Switches Plays Its Role
By setting a closed side waterproof frame, and embedding the line in the side waterproof frame, and by sealing the lead-out slot of the lead wire, it can effectively prevent water and moisture from entering from the side of the product, avoiding The LED circuit and the button circuit have silver paste oxidation, which leads to the failure of product functions. In addition, no through-holes are opened within 5m / m of the upper and lower circuit surfaces from the conductive lines, and the interlayer vent holes are not in communication with the outside world.

Because of this, The waterproof flexible membrane switch usually has a longer service life than conventional membrane switches and can be used in more harsh environments, but the price is relatively high. It is precise because the waterproof frame and the material with high waterproof performance can make the membrane switch form a better airtight seal and protective barrier. Even on rainy days, it can still be used. If you have more questions about the waterproof frame membrane switch, please feel free to contact Niceone, we can customize the membrane switch for you.

Tactile & Non-Tactile Membrane Switches(2021年)

niceone-tech — 2021-10-14T12:40:51+0900

https://www.niceone-tech.com/products/tactile-membrane-switch.html

Tactile Membrane Switches products generally have Dome, and the products can be embossed or not. The combination of the shrapnel and the bottom line will realize the line conduction.

Tactile feedback is very good.
Due to the presence of bumps and shrapnel on the panel of tactile membrane switches, there will be a clearly sound or an obvious tactile effect during operation. The sound and touch can be used to judge whether the product is on.

To provide a better user experience.
Due to technological breakthroughs, even with convex button membrane switches, Niceone-tech can use backlight technology to combine with them to form higher value-added products.

Advantages of Tactile Membrane Switches:
Better tactile feedback:
Compared with Non-Tactile Membrane Switches, Tactile Membrane Switches have a better sense of touch. Due to the use of Dome, you can still hear whether the product is activated in a noisy or dark environment.
More stable electrical performance.
Moisture-proof and waterproof

Because the materials are hermetically bonded together, and because the structure is similar to Non-Tactile Membrane Switches, it has good moisture and waterproof effect. Electronic accessories can be well protected on this basis.

You must now have a certain understanding of metal tactile and non-tactile switches. Membrane switch is a very good electronic accessory, widely used in medical, military, marine, and agricultural, etc. Niceone-tech can provide various types of membrane keyboards/switches. If you need to customize the membrane switch, please feel free to contact us, our contact information is info@niceone-tech.com.

Non-Tactile Membrane Switches
The buttons of Non-Tactile membrane switches are not embossed or only printed with button border ink. The realization of the function lies in the combination of the energization point on the panel or the energization point of the upper line and the line of the lower line to form line conduction. The main difference from Tactile Membrane Switches is that when the button of the Graphic overlay is pressed, there will be no obvious The sound, and does not provide any tactile feedback. The main method to determine the realization of the function is whether there is an optical change on the LEDs or LCD window. It is also possible to use LED backlighting techniques to determine whether the function is realized by judging whether the button or font is lit.

Advantages of Non-Tactile Membrane Switches
Longer life and more cost-effective products
The Non-Tactile Membrane Switches structure does not have bumps and shrapnel, so the unit price will be more economical. At the same time, the life span is longer than Tactile Membrane Switches (life span can reach 5,000,000 times). Since there is no restriction of the dome, the buttons can be relatively closer to the edge. The designable area is more extensive.

Easier to clean
Since Non-Tactile Membrane Switches are flat panels, the product is easier to clean. At the same time, since there is no internal air groove, the waterproof and moisture-proof effect will be better.

Combined with backlight technology to form higher value-added products
Since Niceone-tech has spent a lot of money to research backlight technology in recent years, it has gradually combined Non-Tactile Membrane Switches and backlight technology to form a product that will not be unable to track the keys even if it is used in the dark.

Niceone-tech is a professional membrane keypad manufacturer, we provide human machine interface control module, tactile dome button, metal tactile switch, tactile membrane, tactile membrane switch, tactile dome switch, silicone rubber keypad and etc. Want to know more? Please contact us.

Silver Flex Membrane Switches(2021年)

niceone-tech — 2021-10-14T12:40:21+0900

https://www.niceone-tech.com/products/silver-flex-membrane-switches.html

The most common structure in custom Flex membrane switches is Silver Flex Membrane Switches. The conductive ink, carbon oil, and UV ink are printed on Polyester by screen printing, and the other layers are separated by adhesive. The LED can also be installed in the lower line to form a simple membrane switch with the shrapnel. The simplest structure is a single button membrane switch. The product is very thin, the cost is more affordable and easy to customize. Niceone-tech believes that the metal dome switch has a more obvious feel than the touch screen, and the membrane switch has better auditory, visual, and physiological effects for the touch screen.

What Are the Silver Flex Membrane Switch Design Options?
Digital and/or screen printed on the backside. The effect can be customized according to your requirements including glass, metal, wood, and stone. If the panel is in a more severe environment, we can even use hardened glass and stainless steel as the panel material. It is very important to choose Overlay printing according to requirements.

The window needs raw materials to be transparent, frosted, transparent or colored. The window of the membrane switch is different, and the choice of materials is also very different. When the window is large, and it is required to clearly see the bottom LCD or touch screen. EBG series is a good choice, the material is scratch resistant. If it is just a panel, then PC or Lexan overlay is also feasible

Top Circuit Layer (Dome retainer): This layer usually has three functions: 1. As the Dome Retainer, it ensures that the Snap dome of the circuit layer will not form shrapnel movement due to triggering and closing, resulting in circuit failure and circuit wear. 2. Use 0.1-0.125mm Polyester printing conductive ink, carbon oil, and UV ink as the upper line. This layer structure can also be convex to make tactile feedback better. 3. Can be used as an ESD shielding layer.

Circuit Spacer (switch spacer): Both upper and lower lines are printed with conductive ink, usually thicker tape is used to separate the upper and lower lines to avoid direct conduction of the membrane switch. If the upper circuit is only used as a fixed layer, then the general thickness of the Overlay adhesive + Top Circuit Layer + Lower Circuit Layer should be greater than 0.4mm, otherwise, the panel will squeeze the shrapnel to make them feel worse. Unless the panel is convex, the four-layer structure is less than 0.4mm.

Lower Circuit Layer: The thickness of this layer circuit is usually 0.1-0.188mm. It can be printed with ink, carbon oil, and UV ink. LEDs can also be installed. Some membrane switch panels will choose the copper flex or Printing circuit Board as the circuit. Compared with Polyester, their performance will be more stable. More often applied to the medical and military industries. If it is copper flex or Printing circuit Board as a line, Niceone-tech can even install a variety of components on the line.

Rear Adhesive: There are many choices, but the most commonly used are 3M200MP series or 3M300LSE. According to the different products of membrane switch lamination, Niceone-tech will recommend 3M300LSE if it needs higher viscosity.

Rigid Support Layer: This layer structure is generally used as the last layer of the membrane switch, which can make the structure of the membrane switch component more complete. Usually, the choice of materials is AL, FR4, PC, or steel. If AL is selected, nuts or feet may sometimes be added to the back of the product.

Precautions for custom silicone keypad:
Snap Ratio: The Snap Ratio of the keyboard will affect the tactile feedback and product life. Generally, Niceone-tech recommends that the Snap Ratio be controlled at 40%-60%. If it is less than 40%, the life will be longer, but there is no feeling. In China, we will also call it a trip. The lower the trip, the longer the life span and the worse the tactile feedback.

Conventional rubber keyboard processing:
Usually, PU or hand-feeling oil makes the printing life of the silicone surface longer.
Epoxy treatment: The product becomes more beautiful.
Conductive or non-conductive rubber keypad.
Multiple color options.
Phosphorescent "glow-in-the-dark" material additives.
Silkscreen printed keys.
Laser-etched keys.
Hard coating.
Epoxy coating.
Environmental shielding options.
Printed or laser-etched legends.
Printed circuit board assembly.

The glass fiber cloth in PCB (or printed circuit board) is one of the raw materials of copper clad laminate, which is woven from glass fiber yarn, which accounts for about 40% (thick board) or 25% (thin board) of the cost of the copper-clad board. Therefore, PCB laminate models include FR-4, CEM-1, and G-10. The most commonly used material for PCBs today is FR-4. Simply put, PCB is the most important body of electronic components.

Advantages of PCB Membrane Switch
Niceone-tech believes that although the PCB membrane switch will be more expensive than the silver flex membrane switch, it can still be used in a large area because some of the performance of Silver Flex Membrane Switches cannot meet customer needs. One of the reasons is the welding of electronic original parts. The reason why many silver flex membrane switches are not suitable for installing too many electronic components is that the printed silver circuit and PET cannot withstand the high temperature of welding, but the PCB membrane switch can weld various Components and can withstand high temperatures. The second reason is that absolute pressure, vibration, or shock may damage some components of the screen printed membrane keyboard such as LEDs, but PCB membrane switches can overcome these problems.

Niceone-tech believes that PCB membrane switches are better than Silver Flex membrane switches in several places:

The resistivity is relatively low and the conductivity is high. Because the PCB is gold, tin, and nickel plating.
Use in an environment of absolute pressure, high vibration, and high impact
Compared with the high-resistance and high-defect of the hole filling of the Silver Flex membrane switch, the plated thru-hole resistance of the PCB will be lower, and the defect is also low. It is important that Niceone-tech can solder a large number of electronic components behind the PCB. Ideal for smaller designs where dense circuit patterns or trace routing limitations exist, by using plated thru-hole technology to utilize both sides of the PCB.
Different types of components can be soldered on the circuit board and are more robust.
Support hard soldering
Single-sided, double-sided, and multi-layer designs available

The Most Common Design Features of PCB Membrane Switch
The buttons on Graphic overlays are convex embossed, rim embossed or debossed.
The screen printing method of the product includes digital printing, screen printing or a combination of the two.
Different textures and surface finishes include the Gloss, Matte, Velvet.
It can have a non-tactile touch or polyester or metal shrapnel touch.
LEDs window can use different transparent colors of raw material color or silkscreen.
Transparent white is a more common choice.
The LCD window can be selectively textured and treated with UV hard coating surface
EMI/RFI
backlit membrane switch

In addition to the price, the PCB membrane switch has no advantage, the basic PCB membrane switch performance is completely beyond the Silver membrane switch.

https://www.niceone-tech.com/products/metal-dome-switch.html

Materials for making snap dome and triangle or four-leg metal dome membrane switch:
The metal dome switches and snap dome are sure to be the switch button. If the various switches are separated from the Metal Domes, it loses its meaning, so it is said that the Metal Domes plays a key role in the switch, and it was later known as the metal dome switches and snap dome.

Application of a metal dome: used on button switches, membrane switches, tact keypads, self-locking switches, metal dome switches, and snap dome.

Function of metal dome switches: to power on and off, which can give the operator good tactile feedback.

About the pot pieces:
The pot pieces can be tinned, silvered, gold-plated, and other different surface treatments. Different treatments on the surface can produce different effects. For example, tin plating can solve the problem of heating without fading. In addition, gold plating and silver plating on the surface will increase the pot pieces Gloss has a certain resistance effect.

About the pan-shaped pieces:
The pan-shaped pieces are generally made by customers with drawings provided by us. The types of pan-shaped pieces most used by the guests are round pieces and oval-shaped pieces, also known as waist-shaped pieces and cross-shaped pieces. Triangular pan slices and rectangular pan slices have diameters from 3mm to 20mm, strength from 100gf to 600gf, and special strength pans can reach 6000gf.
The back of the pan-shaped piece can be dotted or not, the round pan-shaped piece is generally five contacts, and one contact, some special needs no contact. In order to facilitate assembly, the pot pieces are generally stuck together with PET, which not only facilitates assembly but also accurately positions.

About its different names:
Metal domes are also known as metal shrapnel. Its English name is meal Dome slices. Sometimes people will say membrane switches. The name of Metal domes is generally based on his purpose. The ones commonly used in industry are called The shrapnel, and used in mobile phones, the keyboard is called the potsticker, and the switch series is called the membrane switch. Single-layer potstickers are generally full-page stickers.

There are many common causes of failure of shrapnel:
The operation is too frequent.
The pressure is too large, the stroke is too high.
The isolation layer is too thick.

Membrane Switch Panel(2021年)

niceone-tech — 2021-10-14T12:38:45+0900

https://www.niceone-tech.com/products/membrane-switch-panel.html

Membrane panel is a type of HMI, in which the structure is generally PET, PC, PVC as the base material, DT, Nitto or 3M as the adhesive material to assemble them together. It is a kind of HMI with more prominent performance and lower prices.

Membrane switch panel is the operating system on many electronic controllers, medical accessories, agricultural products, and it is also the first interface. Color matching and design are particularly important. Fortunately, Niceone-tech's engineers and designers are very good at this type of product. At the same time, we will strictly review whether the customer's drawings and ideas can be realized.

Advantages of Niceone-tech Membrane Switch Panel
At this time, there will be two types of printing methods to overlay the top structure of the membrane panel. Using different screen printing methods will affect cost, usability, and durability. A poor printing method will make the panel coating of membrane switch overlay easy to peel off. Therefore, Niceone-tech has always been committed to quality, and we will pass the 100 grid test every time the screen printing and color printing are performed to prevent the product from peeling off the coating. Fortunately, Niceone-tech has mastered the core technology, which makes the product ink and circuit-level ink have high viscosity characteristics, and the above problems will not easily occur.

The CMYK color printing method can form gradual patterns or colors. Generally, we call this kind of digital membrane switch. The gradual color is not possible with conventional screen printing. At the same time, because color printing is very suitable for bulk goods when the quantity is large, the use of color printing will reduce the cost, but the color error of color printing will be larger. However, the general panel is produced by CMYK color printing. If it is a PET circuit, screen printing is still required.
Screen printing, the most commonly used printing method for membrane switch, uses ink debugging to produce a variety of colors, endowing the products with different colors. But when more colors are involved, we need more screens to create images. Meanwhile, Niceone-tech will choose different screens to produce different circuits to achieve high-precision and low-error circuits products. Screen printing is suitable for small batch production, and it also has higher color requirements and lower error rate. Even sometimes we will adopt the combination of screen printing and CMYK color printing so that a high-quality digital membrane switch with advantages of the two can be formed.

The membrane switch panel is generally thin, if not specially required, the thickness is controlled between 0.7-1.2mm. If the material is too thick, Niceone-tech will advise customers to use stainless steel molds, otherwise, the shape cannot be punched out. Even because the material is too thick, die-cut tooling cannot be used for punching.

Membrane panel:
With a sealed surface, easy to clean and affordable
Can be customized in various shapes and surfaces
Has a big application scope

In recent years, Niceone-tech is committed to researching and developing new types of membrane switches. LGF membrane panel not only has the life of fiber membrane panels but also cheaper than EL membrane panels. At the same time, its uniform luminescence and long life make it very popular in European and American countries.

As a leading membrane switch panel manufacturers, Niceone-tech can offer custom membrane switch panel for various usage. We have the marine membrane switch panel, touch control panel, etc. that can meet high-end requirements. If you need more information, please contact info@niceone-tech.com

Niceone-tech is a professional membrane switch manufacturer, we provide human machine interface control module, membrane switch and panel, membrane panel switch, membrane touch panel, membrane control panel and etc. Want to know more? Please contact us.

What Factors Should The Membrane Switches Manufacturers Consider When Making The Circuit Of The Membrane Switch?(2021年07月23日)

The circuit is the most important factor for evaluating the inherent quality of the membrane switch. The circuit should be constrained by parameters such as current, resistance, withstand voltage, insulation, and life. This is also the penetration of screen-printed products into the multifunctional and high-tech fields. Specifically, to ensure the function of the circuit.First of all, the quality of the screen printed silver paste circuit should be guaranteed and a brief description of how to make the circuit screen

Before making the electric network version, we must first consider the circuit parameters and the structural elements in the circuit to make the requirements of the screen.

(2) The density of the conductive pattern: Although the thickness of the conductive pattern is the basis for laying the performance parameters of the switch. Since the circuit pattern printed by the membrane switches is formed by the aggregation of particles of conductive metal (usually silver particles), printed on its In the material (silver paste), the barrier between the resin connection to the particles, the impurities to the conductor particles, and the screen mesh wire to the metal particles during the screen printing process will affect the density of the conductor pattern, thus Affect the performance of electrical parameters. For the above reasons, in order to allow conductive printing materials, especially the flake-shaped silver particles in the silver paste to pass smoothly, it is necessary to select a slightly lower mesh, and the wire diameter is required to be thinner and the hole width is relatively larger.

How To Do? When We Find The Laser Silicone Rubber Keypad Light Bleed?(2021年07月22日)

niceone-tech — 2021-06-29T17:06:55+0900

https://niceone-tech.com/products/graphic-overlays.html

Niceone-tech customized touch screen hmi panels and custom membrane switches will be based on product application, circuit density, conductivity, resistance, whether many electronic components are required, operating environment, customer budget and whether to pay attention to silver migration.

More and more laser engraved silicone keys installed on a variety of machines , spray laser engraving technology silicone products of many forms , some of the laser engraved silicone keys can not leak light , how should we prevent it ?

First of all, the main forms of producing radium engraved silicone keys are as follows:

1.Directly transparent silicone surface will be printed characters by screenprinting, so that the whole key are transparent,

2.Directly print hollow characters on the surface of transparent silicone rubber keypads.This product is similar to the above one in terms of light transmission, but its side is also transparent;

3. Choice transparent color silicone. We will print oil on the surface, such as grey oil, red oil, black oil, etc., and then paint the oil layer with radium to carve out the characters so that only the characters are transparent and the product side is opaque.The method 3 is the best choice to make this kind of product.

Usually we would advise the customer to choose the third way, but there is a problem of light leakage in this way, how to solve the problem of light leakage?Consider the following approaches:

1. The most direct method is to print the ink to be thicker;

2. Before priting the last layer of ink, apply a layer of base oil, which is used to block light and prevent light leakage;

3. If the distance between the two silicone keys is too small, the structure will affect the effect of oil injection shading, then you can only use the way of oil coating, before the last layer of ink spraying, can not spray the location of a layer of ink shading, but the cost of this way is the most difficult to control, it is not recommended that customers choose this way.

No matter spray thick, add layer of bottom oil or the way of oil.We need to consider not to affect the radium carving process.Because the oil layer is too thick, it is possible that radium vulture will not to remove oil clearly.Niceone-tech factory is a manufacturer specializing in customized silicone rubber keypad products. All processes, including molding, screen printing, spraying, glue dropping and assembly, are independently completed in the factory and provided online by engineering

About Membrane Switch(2021年07月16日)

niceone-tech — 2021-06-29T17:06:24+0900

Membrane switch panel is an operating system that integrates key functions, indicator elements, and instrument panel. It consists of four parts: panel, upper circuit, isolation layer and lower circuit. When the membrane switch is pressed, the contact of the upper circuit is deformed downward, and the contact with the pole plate of the lower circuit is turned on. After the finger is released, the contact of the upper circuit rebounds, the circuit is disconnected, and the circuit triggers a signal.

Circuit principle of membrane switch

The main structure of the membrane switch panel is generally composed of buttons and membranes. The thickness of the membrane switch is generally controlled at about 0.15mm. If it is too thin, there is no rebound force, and the use of the switch is not so sensitive.

When making flat-type switches, when choosing a film, they tend to choose a slightly higher thickness to ensure long-term use of the product. Another type of panel used for circuit contacts requires a slightly thinner type. Only when the diameter of the bubble is compared, a thinner film is selected.

The design of the overall structure of the membrane button is very simple. When you get a touch keypad membrane panel, you only need to take off the button cover to see the circuit and circuit board of the panel.

When the shape of the designed button is relatively large, it is best to choose a film with a thickness of 0.18 mm. This thickness of the film is moderate in thickness and has a good rebound effect. It can be used frequently and is not easily damaged. If the selected film thickness is not enough, it is easy to penetrate. Make the membrane switch insensitive.

Membrane switch panel has many advantages of buttons. Its Circuit principle is outstanding compared with other different types of buttons. It is a lot of conductive metal points welded on a conductive film. Each button can be connected to the same membrane switch. How the buttons of the membrane switch panel work, can achieve different control effects. The membrane switch panel has a barrier layer. Its function is to make a button and the panel react when no one presses.

Membrane touch switches are a kind of electronic switch, also called membrane switch, hmi touch panels or backlit membrane switch. When the operator presses the button of membrane touch switch, the circuit will be activated. On the contrary, when the finger leaves the button, the electricity will be disconnected and the button will return to its original state.This principle of electrical performance is very common in our lives: mice, light bulbs and other touch devices are commonly used.

Membrane switches are often combined with some back panels to provide rigidity to electronic and control panels. Membrane switches are sometimes not glued at the bottom but rigid boards such as FR4, AL, stainless steel, acrylic, polycarbonate, and ABS. The important thing is that the size of the membrane switch panel will be slightly larger than the size of the backplate, and it cannot be completely fit. The most commonly used backplate material is AL as the backplate. When Niceone-tech urgently needs the assembly of support plates and panels, our factory can use CNC machines to make them in-house to shorten the processing time. You can even cut extra expenses. AL back panels could be made with flat or formed back panels with holes, studs, or stand-offs.

In order to hide the back panel, its length and width need to be 0.5 mm smaller than the membrane switch panel; punching and cutting need to be 0.75 mm larger than the membrane switch; the size behind the window needs to be 1.5 mm larger. Niceone-tech has a special CNC The machine will process FR4, AL, and other materials, and provide high-quality touch keypad membrane switches with backplanes. I believe our products will make you satisfied.Set your equipment apart from the competition.

Membrane Switch: An Introduction To Work(2021年07月09日)

niceone-tech — 2021-06-29T17:05:21+0900

https://niceone-tech.com/products/fpc-membrane-switch.html

We can see that many electronic switches exist in much electrical equipment and medical equipment. They have electrical switches made of hard plastic, touch-sensitive resistive screens, and capacitive screens, as well as membrane switches produced by Niceone-tech. The switch is composed of lines, which can be operated or turned off according to the input. What Niceone-tech would like to introduce to you today is the touch keypad membrane switch and its working principle.

About membrane switch:
Membrane switches are different from traditional electrical switches in that they do not have a hard and rigid texture. On the other hand, their materials are often made of softer sheets and elastic materials. Niceone-tech believes that as long as a switch is made of flexible materials and has electrical functions, then the switch can be called a membrane switch.

Why do customers like to use membrane switches as the user interface of the machine?
In the use of membrane switches, due to its easy cleaning, long life, and easy operation as an HMI panel, it is also ergonomically comfortable to use. Compared with traditional hard plastic switches, they are usually harder, but the membrane The switch is relatively soft and easier to be accepted by the human body.

During use, the longer the life span, and the function remains as new, it means that the cost performance will be higher. There is no need to replace parts frequently, even if it is replaced, it is not difficult. This is one of the reasons why it is becoming more and more popular by customers.

Depending on the environment in which it is used, Niceone-tech sometimes assembles silicone buttons and circuits to form a silicone button membrane switch. Combining the corrosion-resistant, long-life, and easy-to-clean nature of silica gel, sometimes silicone keyboard membrane switches are also a good choice. Although the mold cost of the silicone keyboard membrane switch is higher, the single cost is lower, and it is generally used for mass products.

In recent years, Niceone-tech has developed a new type of backlight membrane switch-LGF membrane switch, compared to traditional EL, light-emitting diodes, and optical fibers. The advantage of the LGF membrane switch is based on the original membrane switch button. The button can also emit light, so it can be used in dark places. It can be applied to hunting electrical equipment and medical equipment in the central area. At the same time, the light life of LGF can even reach 10,000 hours. However, the mold and unit price of LGF membrane switches are relatively expensive, but we believe that LGF membrane switches will gradually become the mainstream of the market. And let more people love and use it.
