<p>An electrically functional adhesive transfer for use in the manufacture and/or the design of flexible membrane circuits. Electrical circuit elements (11, 12), instead of being printed directly upon polyester film substrates, are printed upon a carrier sheet (15). A pressure sensitive adhesive (13) is applied over the exposed surfaces of the printed circuit pattern (11, 12) on the carrier sheet (15) and covered by a release paper (14). The circuit later is applied to any desired substrate (44) by peeling away the release paper (14) and mounting the circuit by means of the pressure sensitive adhesive (13). The carrier sheet (15) typically is peeled away after the circuit is adhesively bonded to the substrate (44). The carrier sheet (15) desirably is transparent or translucent in order to facilitate visual alignment of the circuit pattern with the substrate (44) to which it is being bonded.</p> |
