Abstract
Abstract An anisotropic elastomeric conductor is fabricated by stacking a plurality of metal sheets and elastomeric sheets, where the metal sheets have a plurality of parallel electrically conductive elements formed therein. By coating a curable elastomeric resin on the metal sheets, and then curing the resulting layered structure, a solid elastomeric block having a plurality of parallel electrically conductive elements running its length is obtained. Individual elastomeric conductors suitable for interfacing between electronic components are obtained by slicing the block in a direction perpendicular to the conductors. The conductor slices so obtained are particularly suitable for interfacing between electronic devices having planar arrays of electrical contact pads.
