ABSTRACT:
A PC board test fixture translates various stimulation signals produced from a base grid of an automatic test system to randomly positioned test points of a printed circuit board to be tested. The test fixture includes a translator board having conductive pads aligned with probes of the base grid. Conductive pads on the top surface of the translator board are aligned with spring-loaded probes carried by a probe support fixture and aligned with the random test points of the printed circuit board. Conductive feedthroughs connect selected conductive pads on the bottom of the translator board to the randomly located pads on top of the translator board. A computer-executed algorithm compares the locations of the pads on the top and bottom of the translator board to determine the locations of the feedthroughs.
