Abstract:
A socket for use in making connection with a semiconductor chip assembly, having a plurality of electrically conductive joining units connected thereto, said socket comprising:A. a flexible dielectric element having a top surface and a bottom surface opposite the top surface and a plurality of apertures extending from the top surface to the bottom surface and a lip region surrounding each of the apertures;B. a backing element having a first surface, a second surface opposite the first surface and a plurality of holes extending from the first surface to the second surface, said backing element being disposed beneath the flexible dielectric element such that the first surface faces towards the bottom surface of the flexible dielectric element; and wherein each of the holes is disposed under and associated with one of the apertures in the flexible dielectric element and has an effective diameter which is greater than the effective diameter of the associated aperture, such that the lip region surrounding each aperture overlies the hole in the backing element associated with such aperture; andC. a plurality of electrically conductive contacts attached to the backing element, each said contact being adapted to make an electrical interconnection to one of the electrically conductive joining units when such electrically conductive joining unit is inserted into one of the apertures and each said contact having an opening disposed under one of the holes; andwherein the lip regions of said dielectric element surrounding each of said apertures is deflectable to the extent necessary to allow an electrically conductive joining unit having a diameter larger than the effective diameter of the aperture to penetrate through the aperture and to capture the electrically conductive joining unit after it has penetrated the aperture.
