ABSTRACT:
A method for repair soldering of multi-pole miniature plug connectors on printed circuit boards, having signal contact pins in the SMT design and shroud pins in the THR design. The plug connectors have shrouds whose shroud pins project out on the back of the printed circuit board. Preforms are glued onto the SMD signal contact pins, and the repair plug connectors are set into THR holes of the board with their shroud pins. The signal contact pins are soldered using SMT technology. Subsequently, the shroud pins are soldered from the back of the board. The solder connects with the solder eyes of the solder holes on the back of the board, as well as flows into the ring gap between the metallized inside walls of the solder holes and the shroud pins in the circuit board, and produces a material-lock connection. Finally, the shroud pins that project out are shortened.
