PCBA is the SMT upper part on the PCB empty board, and then through the DIP plug-in manufacturing process, it will involve many fine and complicated process flow and some sensitive components. If the operation is not standardized, it will cause process defects or components. Damage, affecting product quality and increasing processing costs. Therefore, in the PCBA chip processing, it is necessary to comply with the relevant operating rules and operate in strict accordance with the requirements. The following describes the operating rules of PCBA processing
