  • 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...

  • How to solve the problem of patch welding porosity in smt patch processing

    In the patch processing of smt patch processing, there is a phenomenon of poor processing called welding pores, which is what we often call bubbles. Welding porosity refers to the holes formed in the welding seam before the gas in the welding pool escapes and stays in the weld. Gas source The gas...
