ABSTRACT:
A contact sheet is provided including two insulative base sheets having a plurality of through-holes formed therethrough in an array pattern and a plurality of conductive contacts interposed between the insulative base sheets. Each contact includes a fixed part bonded to an end of a respective through-hole and an integral moving part contiguous with the fixed part. The moving part includes a contact portion formed as an elastic cantilever. Part of the moving part protrudes from one side of the base sheet inside the through-hole and the contact portion elastically extends from the other side of the base sheet. The total area of the through-hole and the fixed part of the contact is greater than a unit grid area formed by an arrangement of the terminals of an electronic device, and the length of the moving part, including the contact portion, substantially corresponds to the overall length of the through-hole.
