ABSTRACT:
A predetermined number of bond cycles is carried out in order to find optimum bond parameters for a wire bonder. The bond parameters to be optimized are each varied within a predefined range. With each bond cycle, after attachment of the wire to the connection point, the capillary is moved out of the bond position in a predetermined horizontal direction whereby the current flowing through the drive which moves the capillary is monitored and its maximum determined.
