Abstract
Electronic assemblies are fabricated by stacking alternate connecting layers and component layers. The component layers may be virtually any rigid structure having contact regions formed on at least one face thereof. The connecting layers are formed from anisotropic elastomeric conductors which in turn are fabricated by stacking a plurality of conductive sheets and insulating sheets, where the conductive sheets have a plurality of parallel electrically conductive elements formed therein. By introducing a curable elastomeric resin into the stacked structure so formed, and then curing the elastomer, a solid elastomeric block having a plurality of parallel electrically conductive elements running its length is obtained. Individual elastomeric conductors suitable as connecting layers interfacing between adjacent component layers are obtained by slicing the block in a direction perpendicular to the conductors.
