Patent ID: 8403681

Claim:
An electrical connector socket comprising: a base plate with an opening extending therethrough in a vertical direction, and an anisoptropic conductive film received in the opening of the base plate, said anisoptropic conductive film comprising a pressure sensitive adhesive and a plurality of conductive particles dispersed in the adhesive, said anisoptropic conductive film having conductivity only in a thicknesswise direction at room temperature; wherein the conductive particles each comprises a resin core capable of deformation by pressing, a nickel layer coated over the core, and a gold layer coated over the nickel layer, and wherein the adhesive is made of resin, silica gel or rubber; wherein the conductive particles dispersed in the adhesive is in an amount of 0.3 to 5% by volume, and wherein a thickness of the anisotropic conductive film is 0.2 millimeter to 0.5 millimeter; and wherein a cover plate attached to the base plate covering the anisotropic conductive film and a load lever securing the cover plate to the base plate.
