ABSTRACT:
The present invention provides a method of making a sheet material adapted to make bonded electrical connections to an array of closely-spaced conductive terminal pads. The method comprises the steps of providing a thin, flexible, insulating substrate, and squirting a plurality of fine molten strands onto the substrate to form metal strands. The metal strands individually have a cross-section with an area of about 100 to 100,000 .mu.m.sup.2 and the cross-section having a flat section and an arcuate portion. An adhesive or conductive adhesive may be coated over the metal strands, or the adhesive may be provided on the substrate and the conductors imbedded into the adhesive by pressure or heat-sinking the conductors into the adhesive layer.
