What is FR4?
FR4 is the name of a type of epoxy glazing material. fr stands for flame retardant. 4 refers to the factors that differentiate it from other materials. FR4 means two things.

The material.
As a construction material, it refers to epoxy laminates reinforced with glass fibers. Used to make FR4 printed circuit board.

Evaluation.
It is also a unit of evaluation. Epoxy laminates are classified. This classification shows the basic quality of the epoxy resin board.

This classification helps to determine the quality of different types of materials and designs of slabs.

What is FR4 PCB Assembly?
A circuit board with FR4 is called an FR4 PCB (fr4 printed circuit board). It is a type of printed circuit board that mainly uses FR4 boards. Originally, FR4 was used as an insulating layer for the PCB. Next FR4 manufacturer adds a layer of copper to both sides of the FR4 board. This makes it a CCL (copper clad laminate). Thanks to FR4, CCL acts as an insulating material. FR4 gives PCBs their strength. In addition, they perfectly absorb moisture and resist fire. This is why these boards are very popular in the market. There is a high demand for FR4 for PCB assembly. FR4 printed circuit boards are compact and easy to design.

BGA PCB Assembly(2024年04月17日)

GreensTone11 — 2024-04-17T18:35:19+0900

https://www.greenpcba.com/bga-pcb-assembly/

A ball grid array (BGA) is a type of surface-mount packaging (a chip carrier) used for integrated circuits. BGA packages are used to permanently mount devices such as microprocessors. A BGA can provide more interconnection pins than can be put on a dual in-line or flat package. The whole bottom surface of the device can be used, instead of just the perimeter. The traces connecting the package's leads to the wires or balls which connect the die to package are also on average shorter than with a perimeter-only type, leading to better performance at high speeds.

Soldering of BGA devices requires precise control and is usually done by automated processes.

Advantages of China BGA PCB Assembly
Heat conduction: BGA circuits allow heat to pass much more easily from the integrated circuit outwards, reducing overheating problems.

Lower inductance: Because each solder ball in a BGA China circuit is generally only a handful of millimeters large, problems from interference within the circuit are greatly minimized.

Higher-density circuits: As through-hole circuits of pcb assembly BGA were more densely-populated, soldering them accurately without crossover or short-circuits became nearly impossible.

3D Printing(2024年04月17日)

GreensTone11 — 2024-04-17T18:34:38+0900

https://www.greenpcba.com/3d-printing-service/

3D printing is a technology that builds objects based on digital model files, using bondable materials such as powdered metal or plastic, and printing them layer by layer.

The printed content comes from 3D models or other electronic data, and the printed 3D objects can have any shape and geometric characteristics.

3D printing uses computer-aided design (CAD) to create three-dimensional objects through a layered method. Starting from the production of graphic models of the objects to be printed, these are usually designed using computer-aided design (CAD) software packages. Import the files to the 3D printer, and then the 3D printer will complete the work.

The Benefits Of Using 3D Printing In Your Product Design
Rapid Prototyping
3D printing service can manufacture parts within hours. When compared to machining prototypes, 3D printing is inexpensive and quicker at creating parts as the part can be finished in hours.

Print on Demand
Print on demand is another advantage as it doesn't need a lot of space to stock inventory, unlike traditional manufacturing processes. This saves space and costs as there is no need to print in bulk unless required.

Flexible Design
custom 3d printing services allows for the design and print of more complex designs than traditional manufacturing processes.

Cost Effective
As a single step manufacturing process, china 3d printing service saves time and therefore costs associated with using different machines for manufacture. 3D printers can also be set up and left to get on with the job, meaning that there is no need for operators to be present the entire time. As mentioned above, this manufacturing process can also reduce costs on materials as it only uses the amount of material required for the part itself, with little or no wastage. While 3D printing equipment can be expensive to buy, you can even avoid this cost by outsourcing your project to a 3D printing service company.

Minimising Waste
The production of parts only requires the materials needed for the part itself, with little or no wastage as compared to alternative methods which are cut from large chunks of non-recyclable materials. Not only does the process save on resources but it also reduces the cost of the materials being used.

How Does 3D Printing Work?
It all starts with a 3D model. You can opt to create one from the ground up or download it from a 3D library.

3D Software
There are many different software tools available. From industrial grade to open source. We’ve created an overview on our 3D software page.

We often recommend beginners to start with Tinkercad. Tinkercad is free and works in your browser, you don’t have to install it on your computer. Tinkercad offers beginner lessons and has a built-in feature to export your model as a printable file e.g . STL or. OBJ.

Now that you have a printable file, the next step is to prepare it for your 3D printer. This is called slicing.

Slicing: From printable file to 3D Printer
Slicing basically means slicing up a 3D model into hundreds or thousands of layers and is done with slicing software.

When your file is sliced, it's ready for your 3D printer. Feeding the file to your printer can be done via USB, SD or Wi-Fi. Your sliced file is now ready to be 3D printed layer by layer.

Examples of 3D Printing
Adoption of 3d printing manufacturing has reached critical mass as those who have yet to integrate additive manufacturing somewhere in their supply chain are now part of an ever-shrinking minority. Where 3D printing was only suitable for prototyping and one-off manufacturing in the early stages, it is now rapidly transforming into a production technology.

Most of the current demand for 3D printing is industrial in nature. Acumen Research and Consulting forecasts the global 3D printing market to reach $41 billion by 2026.

As it evolves, 3D printing technology is destined to transform almost every major industry and change the way we live, work, and play in the future.

3D printing encompasses many forms of technologies and materials as 3D printing is being used in almost all industries you could think of. It’s important to see it as a cluster of diverse industries with a myriad of different applications.

A few examples:
consumer products
industrial products
architectural scale models & maquettes
reconstructing fossils
replicating ancient artefacts
reconstructing evidence in forensic pathology

There are many custom 3d printing companies, but we are one of the best choices for you.

We offer silk screening, pad printing, painting, and powder coating, and can provide testing and quality compliance checks on all components, including inspection with spectrophotometers.

How Does Injection Molding Work?
The china custom plastic molding process requires an injection molding machine, raw plastic material, and a machined mold. The raw plastic material is first melted in the injection unit and is then injected into the mold — most often machined from steel or aluminum — where it cools and solidifies into the final plastic part. The key steps in the injection molding process are clamping, injection, cooling, and ejection.

Available Material for Injection Molding
ABS: Acrylonitrile Butadiene Styrene (ABS) is an opaque thermoplastic and amorphous polymer and is an ideal choice for applications that require an inexpensive, strong, stiff plastic that holds up well to external impacts.

POM: POM is a plastic material featuring a very high tensile strength, with an outstanding resistance to creep, allowing it to bridge the gaps of material properties between most of the plastics and metals.

Nylon: Nylon plastic (PA) is a synthetic thermoplastic polymer commonly used in injection molding applications.

It's a versatile, durable, flexible material often used to as a more affordable alternative other materials like silk, rubber, and latex.

PC: Polycarbonate (PC) is an amorphous thermoplastic. It is highly transparent, impact-/creep-resistant and can be applied within a wide range of temperature conditions.

PC/ABS: PC/ABS is a thermoplastic made of PC and ABS alloys, which combines the excellent properties of both materials. It is widely used in automotive trims, lampshades, handles and other components.

PVC: PVC plastic is budget-friendly, resistant to environmental degradation, chemicals, and alkalis, and has excellent tensile strength and hardness.

PE: Polyethylene is a thermoplastic polymer with a variable crystalline structure and a vast range of applications depending on the particular type. It is one of the most widely produced plastics in the world.

PP: Polypropylene(PS) injection molding material, is a thermoplastic addition polymer made by combining several propylene monomers.

PS: Polystyrene (PS) plastic is a naturally transparent thermoplastic that is available as both a typical solid plastic as well in the form of a rigid foam material.

https://www.greenpcba.com/fr4-pcb/

What is FR4?

FR4 is the name of a type of epoxy glazing material. fr stands for flame retardant. 4 refers to the factors that differentiate it from other materials. FR4 means two things.

The material.

As a construction material, it refers to epoxy laminates reinforced with glass fibers. Used to make FR4 printed circuit board.

Evaluation.

It is also a unit of evaluation. Epoxy laminates are classified. This classification shows the basic quality of the epoxy resin board.

This classification helps to determine the quality of different types of materials and designs of slabs.

What is FR4 PCB Assembly?

A circuit board with FR4 is called an FR4 PCB (fr4 printed circuit board). It is a type of printed circuit board that mainly uses FR4 boards. Originally, FR4 was used as an insulating layer for the PCB. Next FR4 manufacturer adds a layer of copper to both sides of the FR4 board. This makes it a CCL (copper clad laminate). Thanks to FR4, CCL acts as an insulating material. FR4 gives PCBs their strength. In addition, they perfectly absorb moisture and resist fire. This is why these boards are very popular in the market. There is a high demand for FR4 for PCB assembly. FR4 printed circuit boards are compact and easy to design. FR4 boards are popular because they are cheap and can be used in many electrical devices, GreensTone is an professional China fr4 pcb board manufacturer which you can trust.

GreensTone11 — 2023-09-21T14:49:24+0900

https://www.greenpcba.com/bga-pcb-assembly/

Soldering of BGA devices requires precise control and is usually done by automated processes.

Advantages of China BGA PCB Assembly
Heat conduction: BGA circuits allow heat to pass much more easily from the integrated circuit outwards, reducing overheating problems.

Lower inductance: Because each solder ball in a BGA China circuit is generally only a handful of millimeters large, problems from interference within the circuit are greatly minimized.

Higher-density circuits: As through-hole circuits of pcb assembly BGA were more densely-populated, soldering them accurately without crossover or short-circuits became nearly impossible.
