Shorting pad having a flexible conductive sheet

摘要

A shorting pad probe tip for a substrate tester includes a compliant mandrel, a flexible conductive sheet and a nest plate. The flexible conductive sheet is loosely wrapped around the compliant mandrel. The compliant mandrel and flexible conductive sheet are secured together to the supporting nest plate. At least one side of the flexible conductive sheet is electrically conductive such that when the probe tip is brought in contact with the substrate to be tested, I/O pads on the surface of the substrate become electrically connected. In one embodiment the flexible conductive sheet is metallized polyimide.
