• Some issues that should be paid attention to during the secondary reflow soldering of SMT patch processing

    In fact, in the early SMT production line, the glue dispenser is an indispensable equipment, because the SMD parts that have been glued can be wave soldered, but most of the SMT lines now have almost no such equipment. If you don’t have a dispenser, you have to manually dispense glue. I don’t rec...
