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 flexible 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 dispersed a monolayer of electrically conductive elements which have an average thickness greater than the average thickness of the adhesive layer, and the top edges of which are higher than at least part of the exterior surface of the adhesive layer surrounding the element.
