Patent ID: 7307353

Claim:
A method for forming a portion of a burn-in die test assembly for testing a semiconductor die on a substrate comprising: providing a plurality of circuit traces mounted to the substrate, each end of the plurality of circuit traces forming a pattern on a surface of the substrate, the pattern corresponding to a pattern of bond pads of a semiconductor die; providing at least a portion of an elongated strip of anisotropically conductive elastomeric material comprising a laminate of alternating, substantially parallel sheets of a conductive foil and segments of an insulating elastomer, the insulating elastomer selected from one of a synthetic elastomer material and a natural elastomer material; and disposing the at least a portion of a elongated strip over the pattern between the ends of the plurality of circuit traces on the substrate surface, the plurality of circuit traces for connecting to corresponding bond pads of the semiconductor die by conductive paths formed by the substantially parallel sheets of the conductive foil.
