  • Resistance welded solder crimp for joining stranded wire to a copper lead-frame
    Patent number: 7465606
    Abstract: A method of connecting stranded wire to a lead-frame body 10 includes the provision of a stranded wire 12. It is ensured that insulation is stripped from an end 14 of the stranded wire. An electrically conductive lead-frame connection structure 16 is associated with the lead-frame body. The end 14 of the stranded wire is inserted into the lead-frame connection structure 16 so that the lead-frame connection structure substantially surrounds the wire end. Solder flux is injected so as to be substantially about a portion of the end of the stranded wire. The lead-frame connection structure is placed in contact with a bottom resistance welding electrode 18 or a top resistance welding electrode 20.
