Patent ID: 7446545

Claim:
An anisotropically conductive sheet comprising: (a) an insulating sheet having a thickness, said insulating sheet comprising: an inner layer composed of a heat resistant fluoro-elastomer; thin surface layers composed of a heat resistant engineering plastic on both of an upper surface and a lower surface of said inner layer; and a plurality of through holes extending through said insulating sheet, said through holes having an axis extending the thickness of said insulating sheet and an inner surface; (b) a plurality of electrically conductive wire loops each of said loops having: a generally elliptical shape comprising a long axis and a short axis perpendicular to the long axis, the long axis and the short axis both lying in a plane of the generally elliptical shape; and two wire ends, wherein: said plurality of wire loops are inserted in said plurality of through holes of the insulating sheet such that said long axis of the generally elliptical shape of each wire loop is generally parallel to said hole axis of the through hole in which the wire loop is inserted, and said wire loops and said wire ends are in pressed contact with said inner surfaces of said through holes of the insulating sheet to hold said wire loops in said through holes.
