Title:

SUBSTRATE INSPECTING JIG, AND ELECTRODE STRUCTURE OF CONNECTING ELECTRODE UNIT IN THE JIG

Document Type and Number:

WIPO Patent Application WO/2007/132739

Kind Code:

A1

Abstract:

Provided is a substrate inspecting jig, which can reduce a contact resistance between a contact maker and a connecting electrode unit and which has a stable contact resistance without regard to the number of uses. In order to inspect the electric characteristics of an object substrate, the substrate inspecting jig acquires the electric conductions between a substrate inspecting device body and a plurality of substrate inspection points formed at the wiring pattern of the object substrate. The substrate inspecting jig comprises a group of electrically conductive contacts having two end portions for electric conductions, one of which is forced to contact with one of the substrate inspection points, a contact holder for holding the contact group, and a connecting electrode member including the connecting electrode unit arranged to confront the other end portions of the individual contacts of the contact group and adapted to be connected with the substrate inspecting device body. At least a portion of the side circumference near each of the other end portions is brought, when the other end portions of the contact group and the connecting electrode member are to be connected, into contact with a portion of the confronting connecting electrode unit thereby to establish the electrically conductive state.
