Inspection contact sheet and method of fabricating the same

摘要

An inspection contact sheet for electronic device inspection comprises a three-layer base sheet formed by laminating protective films to both the surfaces of an insulating rubber layer, conductive rubber parts having rubber elasticity and penetrating the base sheet perpendicularly to the surfaces of the base sheet. One of the surfaces of the base sheet is provided with contact pads to be brought into contact with the terminals of the electronic device, and the other surface of the base sheet is provided with contact pads to be brought into direct contact with the terminals of an electronic circuit inspecting circuit member or wiring lines. The terminal pads or the wiring lines have an area greater than the sectional area of the conductive rubber parts.
