The circuit board is often accidentally damaged during assembly or testing. Even after the PCBA is assembled, it will still be accidentally impacted by external forces. Sometimes even the copper pad on the PCB board is lifted by force and floats away.
In the PCBA processing plant, there will be some defective products or boards that have problems and need to be repaired. How should PCBA boards be treated after welding or repair?
