US 2006/0216972 A1 · Method for repair soldering of multi-pole miniature plug connectors

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.

A method for repair soldering of multi-pole miniature plug connectors on printed circuit boards, having signal contact pins in an SMT design and shroud pins in a THR design, comprising the following steps:

providing the plug connectors with shrouds having shroud pins that project out on a back of the printed circuit board, beyond its thickness,
gluing preforms onto SMD signal contact pins;
setting the plug connectors into THR holes of the printed circuit board with their shroud pins;
soldering the signal contact pins using SMT technology;
soldering the shroud pins from the back of the printed circuit board using a manual soldering device, wherein the solder connect with solder eyes of solder holes on the back of the printed circuit board, as well as flows into a ring gap between a metallized (through-contacted) inside wall of the solder holes and the shroud pins, in the printed circuit board, and produces a material-lock connection;
and
shortening the shroud pins that project out of the circuit board.
