Abstract

See full text

Apparatus and method for detecting missing interconnect material. The distance traveled by a bonding tool is measured while the interconnect material is being bonded to a site. Unless it exceeds a predetermined threshold, a signal is generated indicating missing interconnect material. A pivoting system associated mating electrical contacts, and a measurement/comparator are advantageously employed to facilitate this measurement.
