  • Foil for soldering the terminals of an electronic component
    Patent number: 4908337
    Abstract: A foil (15) has cutouts (17) which are bridged over by strips of solder (18, 19). The cutouts (17) are so dimensioned that the strips of solder (18, 19) can be placed transversely over the ends of conductive paths (9-14). The terminals (3-8) of the corresponding electronic component (2) are then placed on the strips of solder (18, 19). Pressure is exerted by means of a ram and heat applied, which leads to the melting of the strips of solder (18, 19) and thus to the soldering of the terminals (3-8) to the conductive paths (9-14).
