  • The process of PCB soldering/Welding

    The process of PCB soldering/Welding

    Welding is a complex physical and chemical process. When using solder copper, with the heating of the iron head and the help of flux, the solder first produces wetting on the welding surface, and gradually diffuses to the metal copper. The adhesion layer is formed on the contact surface of solder...
