How to Get Started in PCB Design

While getting into PCB design used to be daunting and inaccessible for beginners, PCB design resources software opens up a new world of possibilities. What role does PCB printed circuit board design services play in the printed circuit board manufacturing? Let's take a look at the basics of custom PCB board design and how to get started using simple PCB design software right away.

What is PCB design software?
PCB design software is like a window into the minds of other PCB designers. PCB design software is a library of PCB designs solution for other users that simplifies collaboration and tests new models for the entire community of hobbyists and professionals. Using a high speed electrical PCB design software, you can effectively create schematics and then transform them into a PCB with all the precise details. Many PCB circuit board design companies offer their software free of charge so that users can complete the process without having to convert files or add more steps. No more sense of frustration about drilling or hand etching!

First, you need to understand the content of the prototype. You can be creative in beginning step of PCB design and prototyping. You can improve the electrical products you have already owned, or even make one by yourself. For people who want to customize remote work settings, perhaps you'll design a PCB to improve the keyboard or computer.

Or, if you want to keep the kids entertained, maybe you'll create a fun LED plate, holiday lighting ornament or toy. If you're a big kid yourself, try walking on all fours and building your own drone. Because the PCB is customizable and exists in every electrical system, the possibilities are endless. Once you have an idea, you'll find a community of tinkerers who can give you tips and tricks based on trial and error.

Next, look for the right PCB circuit board design and manufacturing software for your purposes. There are a plethora of PCB design software tools on the market, many of which are free. Be sure to select the one connected to the PCB manufacturer. This is important because the free PCB software will allow you to use all the resources in the library to create schematics and convert them to PCB, while also freeing you from having to worry about the files created by the software whether being compatible with your PCB manufacturer. If you design your PCB, but because the manufacturer you choose doesn't accept your file type, you can't build it, it will be a big shame.

At the beginning, you might first design a PCB prototype. Using PCB design software is a low-risk and inexpensive way to do modification work. It gives you the freedom to learn from your mistakes. Some softwares also allow you to virtually test prototypes to make sure all the components are in place or to help you spot areas in your design that might be problematic.

Once you're completely satisfied with the prototype, you can start printing. If you want to take advantage of free PCB design software that connects to a PCB manufacturer, this process is easy and quick. You will immediately have a customized PCB to launch the latest product.

The best thing about novices is their curiosity and creativity. If you start dabbling in PCB design, don't get discouraged and give up. Everyone starts out as a beginner, and they slowly and gradually develop more and more complex designs. With so many blogs and forums, you'll be able to find advice from experienced gurus to overcome any obstacles. Free PCB design resources software will give you the extra confidence you need to keep innovating. Eventually, you will be able to carry out complex PCB designs like flex PCBs and rigid PCBs with single layer, double layer, multilayer!

Wire Harness PCB Assembly(2021年12月11日)

zfpcba — 2021-12-06T17:02:27+0900

https://www.zfpcba.com/pcb-assembly/wire-harness-pcb-assembly.html

In today's competitive world, wire harness assembly board manufacturers have been striving to provide unique solutions that provide added value to their services. This also adds a modification to provide a personalized approach for each project, including the development of engineering support, strong supplier management, timely inventory, strict mass production inspection/testing, and raw materials from certified suppliers. Therefore, the competition to provide quality, inspection, technical support, engineering, and customized power pack packaging in terms of providing PCB wire harness solutions is still not over, because there are no more innovations on the market. ZF provides custom wire harness cable assembly board services with customers.

What Is the PCB Wire Harness Assembly?
A PCB automated wire harness assembly is sometimes called a cable or wiring loom. It arranges multiple groups of wires and/or cables into a single unit to protect and organize the various connected terminals and connectors. The shape or layout of these terminals and connectors routes the connectors to the various connection points of the assembly.

As a professional wire harness assembly company and wire harness assembly manufacturer, ZF Electronics has decades of experience in PCB assembly manufacturing, custom wire harness assembly manufacturing, and sub-assemblies for our commercial and industrial partners.

Wire Harness Assembly Board Design
The harness design is highly customizable because the harness is usually designed for a specific application. ZF Electronics accept individualized customer service. Please send us your detailed requirements if you are in need of wire harness cable assembly boards.

Wire Harness Assembly Process
The first station of the Wire Harness Assembly is the opening process. The accuracy of the opening process is directly related to the whole production progress. Once an error occurs, especially the opening size is too short, it will lead to rework of all stations, time-consuming and laborious, and affect the production efficiency. Therefore, when preparing the wire opening process, we must reasonably determine the wire opening size and stripping size according to the requirements of the drawing.

The second station of making the wire harness assembly board is the crimping process. The crimping parameters are determined according to the terminal type required by the drawing, and the crimping operation instructions are made. If there are special requirements, it is necessary to indicate them on the process documents and train the operators. For example, some wires need to pass through the sheath before crimping. It needs to pre-assemble the wires first, and then return from the pre-assembly station before crimping; In addition, special crimping tools are used for puncture crimping, which has good electrical contact performance.

The third station of manufacturing the harness assembly board is the pre-assembly process. First, prepare the pre-assembly process operation manual. In order to improve the general assembly efficiency, the pre-assembly station should be set for complex wire harnesses. The rationality of the pre-assembly process directly affects the efficiency of the general assembly and reflects the technical level of process personnel. If the pre-assembly part is less assembled or the assembly wire path is unreasonable, it will increase the workload of the general assembly personnel and slow down the speed of the assembly line. Therefore, the process personnel should often stay on the site to summarize.

The final step to make the wire harness assembly board is the final assembly process. Be able to compile the assembly platen designed by the product development department, design the specifications and dimensions of tooling equipment and material box, and paste the numbers of all assembly sheaths and accessories on the material box to improve the assembly efficiency. Prepare the assembly contents and requirements of each station, balance the whole assembly station, and prevent the situation that the workload is too large and the speed of the whole assembly line is reduced. To achieve station balance, the process personnel must be familiar with each operation, calculate the working hours on-site, and adjust the assembly process at any time.

Advantages of Wire Harness Assembly
Protecting the Project from Direct Damage
Protection Against Compromised Wires
Preventing Direct Physical Damage
Preventing Damage from Heat
Improving the Flow of Air Within the Chassis

Turnkey PCB Assembly(2021年12月10日)

zfpcba — 2021-12-06T17:02:00+0900

https://www.zfpcba.com/pcb-assembly/turnkey-pcb-assembly.html

For companies of all sizes, a complete turnkey PCB assembly has several significant advantages. Turnkey PCB assembly means that the PCB supplier is responsible for all aspects of the PCB project. This means purchasing parts, manufacturing and assembly.

Advantages that small businesses can benefit from turnkey PCB assembly
1. Save time
Through the turnkey PCB assembly factory to deal with the entire PCB assembly, the obvious advantage is to save the precious time of the customer team and focus on other aspects of the business, which is their expertise. As a customer, you don't need to spend time and effort to find cost-effective quotations for individual components, go through the trouble of purchasing them, and then put all these quotations together. From a cost perspective, this is also very effective, because the pricing of turnkey PCB assembly services is far more effective than bundled services.

2. Help you find problems at the beginning
The main advantage of using turnkey PCB manufacturing assembly in the prototype stage is that any problems can be detected early. In fact, once you share the netlist file with the turnkey manufacturer, he can point out errors (if any). These errors can then be corrected on their own in the design phase of PCB fabrication and assembly, rather than making expensive changes after you are ready to complete the entire production, or worse when you have completed production and need to make changes.

3. Better management
The significant advantage of turnkey assembly among the circuit board assembly services, is that you do not need to deal with multiple suppliers. In addition to saving time, this has many other advantages. What you also need to save is the possibility of misinformation when dealing with multiple suppliers. You may only have one point of contact with the turnkey supplier, which makes the process seamless. Since delivery schedules are critical, the slightest misunderstanding between suppliers can cause errors in the entire schedule and lead to costly consequences. With turnkey PCB assembly suppliers, you can rest assured because the entire responsibility for timely delivery lies with them.

4. Help estimate manufacturing costs
Financial planning can also be done well with the services of turnkey PCB assembly service. In fact, the cost of early prototypes can largely estimate your future manufacturing costs. Due to the high unit cost, just specify the quantity you need and let the turnkey service provider provide you with the cost. In fact, if you indicate the number of units required per month instead of a large batch of units, the manufacturer can usually quote the effective cost, because you may not want to start a large-scale production run. Turnkey PCB assembly suppliers also provide you with the advantage of combining multiple small orders into one large order at a reasonable PCB circuit board price, so they can help you enjoy economies of scale, which may not be available to you independently.

Other services of turnkey PCB assembly suppliers
Turnkey PCB assembly suppliers often provide other services, including inventory, sales and shipping. For small businesses and start-ups, the importance of these services should not be underestimated, because you do not have to spend time, energy and manpower in these aspects, and you can control costs, so as to provide you with a competitive advantage.

SMT PCB Assembly(2021年12月09日)

zfpcba — 2021-12-06T17:01:05+0900

https://www.zfpcba.com/pcb-assembly/smt-pcb-assembly.html

Most of today's mass-produced electronic hardware is manufactured using surface mount technology or SMT. In addition to providing many other advantages, SMT PCBS has a long way to go in accelerating PCB production time. ZF is a SMT PCB assembly supplier in China that masters surface mount PCB assembly technology.

SMT assembly china
The basic surface mount technology (SMT) concept of basic through-hole manufacturing continues to provide significant improvements. By using SMT surface mount prototyping, the PCB does not need to be drilled. In addition to increasing a lot of speed, this significantly simplifies the process. Although SMT board assembly may not have the strength of through-hole mounting, they provide many other advantages to counteract this problem.

The process of SMT PCB assembly is as follows:
1. PCB production, this is the stage of PCB actual production of solder joints;
2. The solder is deposited on the pad, allowing the component to be fixed to the circuit board;
3. With the help of the machine, the components are placed on precise solder joints;
4. Bake the PCB to harden the solder;
5. Check the completed components.

The difference between SMT and through hole includes:
The widespread space problem in through hole vias PCB mounting is solved by using surface mount technology. SMT assembly service also provides design flexibility because it provides PCB designers with the freedom to create dedicated circuits. Reducing component size means that more components can be accommodated on a single circuit board, and fewer circuit boards are required.

The components in the PCBA SMT printed circuit board assembly installation are leadless. The shorter the lead length of surface mount components, the smaller the propagation delay and the smaller the package noise. The density of components per unit area is higher because it allows components to be mounted on both sides. It is suitable for mass production, thereby reducing the PCB printing cost. Reduced size can increase circuit speed. This is actually one of the main reasons why most PCB and PCBA manufacturers choose this method. The surface tension of the molten solder pulls the component into alignment with the pad. This in turn will automatically correct any small errors that may have occurred in component placement. SMT has proven to be more stable under vibration or large vibrations. SMT parts are generally cheaper than similar through-hole parts.

Importantly, SMT can greatly shorten the production time because no drilling is required. In addition, SMT components can be placed at a rate of thousands of placements per hour, while the installation volume for through-hole mounting is less than a thousand. This in turn leads to products being manufactured at the envisaged speed, which further shortens the time to market. If you are considering speeding up PCB production time, then SMT is clearly the answer. By using design and manufacturing (DFM) software tools, the need for rework and redesign of complex circuits is significantly reduced, and the speed and the possibility of complex designs are further improved.

2. The use of SMT
With the powerful advantages provided by SMT, they have become today's main design and manufacturing standard, which is surprising. Basically, they can be used in any situation where high reliability and high-volume PCBs are required.

Prototype PCB Assembly(2021年12月08日)

zfpcba — 2021-12-06T16:59:14+0900

https://www.zfpcba.com/pcb-assembly/prototype-pcb-assembly.html

Designing the layout and requirements of the prototype is just the first step in PCB development. Once the design is completed and you want to use PCB layout/design software tools for analysis, the next step is to assemble the prototype PCB. Many engineers turn to third-party suppliers to manufacture prototype circuit board assembly, even the very small number of prototypes. ZF Electronics are able to provide fast prototype PCB assembly services to customers with a reasonable prototype PCB assembly price.

Why we need prototype PCB assembly?
In order to quickly assemble PCB prototypes, conventional PCB mass production relies on a fixed process to provide the most consistent results. Thus, PCB prototype and assembly is in great demand at that time. The goal here is to distribute high-quality circuit boards without any prototype assembly errors in order to keep the production process smooth.

Requirements of prototype PCB assembly process:
The PCB panel must be manufactured in accordance with all necessary industry standards, and its design must be optimized to meet RoHS and other compliance-related regulations.

The circuit board must be fully assembled, and any part replacement of the prototype version used for testing and debugging must be reconfigured with conventional production-level components.

All DFM requirements must be included in the production design. This includes fast PCB assembly design and test rule design to achieve maximum production yield.

In order to meet any industry safety and standard testing that may be required, all documentation requirements must be fully met.

Mixed Technology PCB Assembly Services(2021年12月27日)

zfpcba — 2021-12-06T16:58:43+0900

https://www.zfpcba.com/pcb-assembly/mixed-technology-pcb-assembly.html

ZF Electronics, as one of the top printed custom circuit board manufacturers and PCB manufacturing companies in China, can provide customers with single-sided PCB, double-sided FR4 PCB, metal core PCB, heavy copper PCB, rigid PCB and rigid-flex PCB.

The printed circuit board (PCB) is the core of every electronic device we connect today. These PCBs basically interconnect electronic components by establishing conductive paths through copper pads and connecting wires. Therefore, the mixed PCBA technology assembly process has become one of the most interesting concepts in electronics.

Most PCBs use through-hole technology assembly (THT), surface mount technology assembly (SMT) and mixed technology PCBA assembly processes.

Mixed Technology PCB Assembly Capabilities and Equipment Used at ZF
ZF Electronics has several production lines, and each production line is equipped with high-quality production machines and professional workers, which can meet the needs of various types of PCB assembly methods.

Mixed Technology PCB Assembly Services at ZF
We are characterized by one-stop procurement of components, SMT patches, THT plug-ins and finished product assembly and processing to provide the best quality products and services for your electronic product needs.

Different kinds of technology PCB assembly:
Traditional PCB assembly process
1. Application of solder paste
2. Component placement
3. Reflow
4. Check
5. Insert through-hole parts
6. Final inspection and cleaning

Through-Hole Technology Conference (THT):
1. Component placement
The components are installed manually by experienced engineers during PCB manufacturing assembly. The installation process of manually picking and placing components requires maximum precision and speed to ensure component placement. Engineers should follow THT standards and regulations to achieve the best functionality.

2. Inspection and component calibration
The PCB board matches the design transportation frame to ensure the precise placement of the components. If any misallocation of components is found, it will only be corrected at that time. Correction is easier before welding, so the position of the component is corrected at this stage.

3. Wave soldering
In THT, wave soldering is performed to cure the solder paste and keep the component intact at its specific location. In wave soldering, the component-mounted PCB board moves over the slowly moving liquid solder, and the liquid solder is heated at temperatures above 500°F. It is then exposed to a cooler to solidify the connection.

Surface Mount Technology Assembly (SMT):
The PCBA steps followed in SMT assembly are as follows:

1. Application/printing of solder paste
Refer to the design template and apply the solder paste to the board through a solder paste printer. This ensures that the solder paste is printed in a satisfactory quantity at a specific location.

2. Component placement
The placement of components in SMT components is automatic. The circuit board is sent from the printer to the component mounting rack, where the components are picked up and placed by an automatic mechanical pick-and-place mechanism. Compared with manual processes, this electronic assembly fabrication technology saves time and also ensures the accuracy of specific component positions.

3. Reflow soldering
After the components are installed, the PCB is placed in a furnace, and the solder paste is melted and deposited around the components. The PCB passes through the cooler to fix the component in this position.

Surface mount technology (SMT) is more efficient in the complex PCB assembly process.
Due to the increasing complexity of electronic equipment and PCB design, mixed assembly types are also used in the industry. That is, the mixed technology PCB assembly process is a combination of THT and SMT.

Details of Mixed Technology PCB Assembly
PCBA processing and assembly mode mainly depend on the type of surface assembly components, types of installed components, processing equipment conditions and actual production line conditions. PCBA processing can be divided into three types: single-sided mixed loading, double-sided mixed loading and full surface assembly, with a total of six assembly methods.

1. Single side mixed loading
The circuit board used for assembly is a single-sided PCB. Single side hybrid assembly means that the SMT patch and THT plug-in components are mixed on different sides of PCB, the welding surface is a separate side, and the patch surface is another separate side. This kind of assembly method adopts single-sided PCB and wave soldering (now double-wave soldering is generally adopted). There are two specific assembly methods:
(1) First paste and then insert: that is, SMC / SMD is first pasted on surface B (welding surface) of PCB, and then THC is inserted on surface A.

(2) Insert first and then paste: that is, insert THC on the side a of PCB first, and then paste SMD on side B. This kind of assembly is widely used in the assembly of TV sets, radios and other products.

2. Double-sided mixed loading
The circuit board used for assembly is a double-sided PCB. SMT patch and dip plug-in can be mixed and distributed on the same side or both sides of PCB. Double sided hybrid assembly purchase double-sided patch, double wave soldering or reflow soldering. There are also differences between SMC / SMD pasted first and SMC / SMD pasted later in this kind of assembly method. Generally, it is reasonably selected according to the type of SMC / SMD and the size of PCB, and the first paste method is usually used. There are two assembly methods commonly used in this class:
(1) Same plane mode of SMT element and dip element: SMT patch element and dip plug-in element are on the same side of PCB; Dip plug-in components are available on one or both sides. Generally, SMC / SMD is pasted before the plug-in dip.

(2) There are SMT chip components on one and both sides of dip components: put surface assembled integrated chip (SMIC) and tht on side a of PCB, and SMC and small shape transistor (SOT) on side B.

3. Full surface assembly
All circuit boards assembled are single-sided and double-sided PCB (or ceramic substrate). On the PCB, there are only SMT patch components and no tht components. Because the components have not been fully SMT, there are few such assembly forms in practical application. There are two assembly methods for this type: single-sided surface assembly and double-sided surface assembly.

Low Volume PCB Assembly(2021年12月20日)

zfpcba — 2021-12-06T16:58:00+0900

https://www.zfpcba.com/pcb-assembly/low-volume-pcb-assembly.html

As PCB becomes an indispensable part of more and more devices, PCB prototyping is at the highest level in history. As the company continues to innovate, sometimes small batch PCB assembly, low volume PCB assembly is required, which can provide high turnaround times without letting the manufacturer fall into a high inventory that he cannot use.

The advantages of low volume PCB assembly
Here are some obvious advantages of low volume PCB assembly china that is of great value to manufacturers:
(1) Cost advantage
Although the traditional economies of scale are known to have large production volumes, low volume PCB assembly has significant cost advantages in the ever-changing technical solutions. First, you won't get more production boards than you need. In addition, as technology changes, circuit boards will not become redundant.

In the prototype stage, you often improvise products in terms of design and functionality. Low-volume production means you will not encounter defective products. In addition, since you can outsource PCB circuit board assembly in low volume, this means lower management costs for your own business. You can also save valuable time that can be used in other production areas. For lower volume, you can also save on storage costs, just in case you encounter a large inventory load, if the prototype fails, it will also cause excess inventory. Therefore, low-volume PCB assembly can provide a low-cost test method; otherwise, if you choose small volume PCB assembly batch PCB, then you need to be sure about its large cost.

(2) Turnaround time
Low batches also have fast turnaround times. Therefore, you can quickly assess whether there are any design changes. This in turn shortens the time to market and can become a source of significant competitive advantage in today's world.

(3) Agile
If there is an attribute between business success and failure, then the enterprise's agility to respond to change. Low volume PCB assembly provides this advantage for companies, because companies will not encounter mass production and have the advantage of fast turnaround time. By better understanding whether there are any defects in the product, regardless of whether the design requires any changes, companies can be very agile to integrate the product with customer needs. There is no doubt that the chances of success are increasing.

(4) Quality final product
PCB's turnaround time is a fast prototyping and the ability to detect defects early, your advantage lies in improving the product, so as to enter the market with high-quality products. This goes a long way in improving credibility because the product has been successful in the market and has brought a reputation to the PCB assembly factory.

The feasibility of low volume PCB assembly for other businesses or investors
It is also feasible for startups and hobbyists. Business today is no longer just the domain of large commercial companies. Through low volume PCB assembly and the low cost associated with testing ideas, the business has become a level playing field. For small businesses and hobbyists, it is easy to test their ideas without having to invest a lot of money. For startups that want investors, in addition to the business plan on paper, it is easy to obtain a proof of concept.

All in all, low volume PCB assembly has many advantages, from saving management costs through outsourcing work. Small order sizes can automatically shorten the turnaround time. In addition, it is a simple and low-cost method to test product design concepts without incurring significant costs.
