What is the gold finger in PCB
Mar 27 , 2021
The gold finger of PCB is mainly used for computer hardware such as: (between the memory stick and the memory slot and the graphics card slot, etc.). All signals are transmitted through the golden fingers in the PCB. This type of design requires high wear resistance and conductivity on the surface of the pad. Its arrangement is similar to a finger, so it is called "golden finger". The fu...

What is the difference between PCBA wave soldering and manual soldering
Apr 24 , 2021
Welding is an important process in PCBA processing. If we do not grasp it well, short circuit and other faults will occur during our testing. If it is serious, it will directly affect the life of the product. Therefore, no matter what welding technology we use, we should ensure that it is satisfied. The basic requirements of PCBA welding can ensure a good welding result. PCBA soldering is divided ...

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...

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...
