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...

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 ...
