Abstract:
1. A method of measuring electrical characteristics of a probe under mechanical load comprising: providing a sensor having a tip with an inner bearing surface and an outer bearing surface, the outer bearing surface being circumjacent to the inner bearing surface, the inner and outer bearing surfaces being non-coplanar with respect to one another, the sensor having a conductive portion formed in the inner bearing surface; overdriving the sensor into contact with a first plurality of probes such that a predetermined probe of the plurality of probes is in contact with the conductive portion of the inner bearing surface, thereby forming a part of a test circuit while the probe is under a mechanical force due to the overdriving, the outer bearing surface overdriving at least one other of the plurality of probes an amount that differs from the predetermined probe that is in contact with the conductive portion of the inner bearing surface; and, moving the sensor out of contact with the plurality of probes and subsequently overdriving the sensor into contact with a subsequent plurality of probes.
