  • Bond signature analyzer
    Patent number: 4998664
    Abstract: A feedback signal of an ultrasonic generator (13) employed in a ball bonder (11) is sampled by an analog-to-digital converter (23) under control of a microprocessor (25) to provide a "bond signature" indicative of bond quality. The microprocessor (25) then compares the bond signature to limits representing a good quality bond to provide an indication of a good or failed bond. The indication may be visually provided by projecting the bond signature and limits on a display (27), as well as automatically provided by a programmed comparison.
