Patent ID: 8020746

Claim:
Method for generating a bond between a wire and an electrical contact member, comprising the steps of: pressing a first surface of a portion of the wire against a second surface of the electrical contact member with a first force while vibrating the portion of the wire along the second surface in order to generate a bond, determining the time dependent vibration amplitude of the portion of the wire during the generation of the bond, determining the time dependent deformation of said portion of the wire due to said applied first force and said vibration during the generation of the bond, and generating a time dependent first signal using at least said amplitude and said deformation during the generation of the bond that represents a minimal force that has to be applied to the bond along or across the second surface in order to physically break the bond at a considered time during generation of the bond, wherein an optimal first signal is determined before the generation of the bond, wherein the optimal first signal defines an optimal bond during generation of said optimal bond and at least one control parameter is adjusted during generation of the bond depending on the difference measured between said optimal first signal and said first signal during generation of the bond.
