Abstract:
A substrate for inspecting an electronic device used for an electrical test of the electronic device having bump-shaped connection terminals, comprising:an insulating substrate comprising first and second sides and first and second sections, and opening sections, the diameter of each opening being determined so that the connection terminal can be inserted into and drawn out from the opening, penetrating the insulating substrate on the first side of the first section of the insulating substrate, on which the electronic device is mounted, said openings corresponding to an arrangement of the connection terminals; and wiring patterns, each of which is composed of a pad section being exposed onto a bottom face of the opening so that the pad can come into contact with the connection terminal so as to accomplish electical continuity, a connecting pad section disposed in the second section, which is adapted to contact a contact terminal so as to accomplish electrical continuity, a wiring section for electrically connecting the pad section with the connecting pad section, and a first elastic material layer disposed in the first section, each disposed on the second side of the insulating substrate.
