Abstract
An anisotropically electrically conductive composition having the capability to conduct heat isotropically when used as an electrical interconnection medium between a pair of electrical conductors, paths, traces, or the like. The composition comprises a mixture of electrically conductive particles in an amount below the percolation threshold for volume conduction for such composition, and electrically non-conductive, but thermally conductive particles, such as metallic oxides, within a polymeric matrix. Preferably, the conductive particles are present in an amount of no more than about 15%, by volume, and the electrically non-conductive particles are present in an amount of about 15 to 35%, by volume.
