ABSTRACT:
Sheet material useful for making bonded electrical connections, especially to sets of small side-by-side terminal pads. In one typical form, the sheet material is an elongated tape comprising an elongated insulating backing; a plurality of narrow spaced parallel elongated electrically conductive stripes on the backing; and electrically conductive adhesive disposed over the stripes comprising a layer of adhesive material in which are contained a monolayer of electrically conductive elements which are thinner than the adhesive layer. The surface of the adhesive layer that contacts a substrate is configured so that at least a portion of the area of the surface is recessed below other areas of the surface, whereby when the adhesive layer is heated and pressed against a substrate, adhesive material may be displaced into the recessed areas and allow the electrically conductive elements to be brought into close electrical association with the substrate.
