Abstract

This process permits the attachment of wires to screened metal pads that lack a heavy gold surface layer. In this process wires to be bonded to pads are tacked in place with an ultrasonic bonder with the power increased from the standard 2.0 setting to 2.6 on the supply. Each ultrasonically tacked bond is then permanently secured in place with a microweld or a reliable bond.
