Patent ID: 8076612

Claim:
Method for welding at least one wire conductor to electrical contact points disposed on a contact area of a conductive film to provide a wire-carrying conductive film adapted for connection to a circuit board support in order to produce a printed circuit board, the depth or diameter of the we conductor being greater than the thickness of the conductive film, the method comprising (a) conducting the welding in a welding area of the conductive film; (b) contacting the conductive film at least during the welding with a thermal isolation plate having a thermal conductivity which is lower than that of the conductive film; (c) removing the wire-carrying conductive film from the thermal isolation plate and then connecting the wire-carrying conductive film to a circuit board support; and (d) forming a printed circuit board by partially etching away the conductive film connected to the circuit board support to electrically isolate the electrical contact points.
