Patent ID: 7836587

Claim:
A process of repairing a contactor apparatus, the process comprising: providing a substrate configured for a set of spring probes to be attached to the substrate such that contact tips of the spring probes are disposed in a tip pattern corresponding to a pattern of terminals of electronic devices to be tested, a plurality of attached spring probes being attached to the substrate, wherein each of the attached spring probes comprises a base attached to the substrate and electrically connected to a terminal of the substrate, the contact tip spaced away from the substrate, and a spring body extending between the base and the contact tip; attaching a replacement spring probe to the substrate in an orientation in which a replacement contact tip of the replacement spring probe is oriented such that the replacement contact tip is disposed in the tip pattern with the contact tips of the attached spring probes to correspond to the pattern of terminals of the electronic device to be tested; wherein: the replacement spring probe comprises a replacement base and a replacement spring body between the replacement base and the replacement contact tip, and the attaching comprises: electrically connecting the replacement base to a terminal of the substrate with an electrically conductive adhesive material, and adhering the replacement base to the substrate with a non-conductive adhesive material deposited at least in part over the conductive adhesive material, the non-conductive adhesive material being a stronger adhesive than the conductive adhesive material.
