Fixtureless automatic test equipment and a method for registration for use therewith

摘要

Fixtureless automatic test equipment for testing a printed wiring board having electrically conductive elements. The automatic test equipment of the present invention includes an array of modular integrated switching circuit (MISC) devices and test instrumentation fore determining the functionality of a workpiece. Each MISC includes an array of semiconductor dies mounted on a PWB interconnector for kiss touch deployment on a workpiece. All the PWB interconnectors form a test mattress of probes for deployment against a bare workpiece. Each semiconductor die includes a matrix of switching cells of which each switching cell terminates in a terminal. The PWB interconnector of each MISC connects the switching cell terminals to probes forming part of the test mattress.
