ABSTRACT:
A return line for a probe station includes a sheet-like conductive strap having a first end connected electrically to a first probe and a self-coiling second end connected automatically detachably to a second probe, as by insertion of the second probe centrally within the coils of the second end. If the spacing between the probes exceeds a maximum distance, the strap harmlessly disconnects. The flat central portion of the strap automatically tracks any reductions in the spacing between the probes, which enables fast probe travel and minimizes noise pickup. Preferably a spindle rotatably engages the coiled probe and has a post member that carries the second end of the strap to a far side of the probe to improve tip visibility and electrical connection during close-in probing.
