What is the test principle of PCB and PCBA
May 15 , 2021
PCBA , it is after put the components on PCB,also can say that PCB plus assembly of electronic components process. However, each PCBA part needs to undergo PCB testing and PCBA testing to verify the functions of the circuit board, verify whether the PCB and PCBA meet the design requirements, and ensure that each product does not have quality problems. The test principle of PCB:...

Printed Circuit Boards Manufacture
May 29 , 2021
PCB are customized products. They can be designed and manufactured according to various flexibility, size and configuration to adapt to different electronic products. Whether it is a simple single-layer rigid circuit board, or a highly complex multilayer flexible circuit board or rigid flexible printed circuit board. PCB design is a kind of special software called CAD(Auto desk Computer Aided...

Chip out of stock!How does the PCBA factory survive and development
May 29 , 2021
Affected by international trade competition and fluctuations in the chip industry, since the end of 2020, not only domestic chip prices have soared, but also abroad. For example: ST, ADI, TI and other well-known brand chips, without exception, doubled or even dozens of times the price, making manufacturers and many electronic product research and development companies miserable, including the PCBA...

What is rigid flexible PCB
Jun 07 , 2021
Rigid flexible printed circuit board is a hybrid circuit board design that integrates elements of hard PCB and flexible PCB circuits. Rigid flexible printed circuit boards are rigid at certain points on the circuit board and flexible at other points. Therefore, the flexible part of the PCB circuit can be folded or continuously bent, but the shape of the area for additional support needs to be...

PCBA product development process
Jul 01 , 2021
First of all, we need to know what kind of functions our electronic devices want to achieve, and it is important to determine whether the components can meet the requirements of electronic devices. If the electronic equipment components meet the functional requirements, engineers need to evaluate from the aspects of functional requirements, performance requirements, technical support, cost evaluat...

Why does PCBA use three anti-paints
Jul 07 , 2021
Three anti-paints are used to protect circuit boards and related equipment from environmental erosion, thereby prolonging the service life of the product and improving the reliability of the product. Three-proofing means: moisture-proof, salt-fog-proof and static-proof. It is a thin protective coating for electronic circuits and components, which can enhance the moisture resistance and pollut...

Where is AOI mainly used for
Jul 12 , 2021
With more and more advanced electronic equipment, the wiring on the PCB (printed circuit board) has become finer, the components have become smaller and the high density of assembly has also been improved. Now the visual inspection does not meet the requirements of SMT assembly quality inspection. Therefore, AOI (Automatic Optical Inspection Electronic Equipment), as a key method for detecting the...
