Abstract:
A method of forming a resistor comprising a patch of electrically resistive material and patches of a layer of conductive material in electrical contact with said patch of resistive material at spaced apart locations, the method comprising,a) providing a metal foil layer,b) providing a layer of electrically resistive material adhered to said metal foil layer,c) covering selected portions of said resistive layer) with photoresist,d) etching non-covered portions of said resistive layer from, said metal foil layer),e) removing remaining photoresist,f) laminating a polymeric support material to the resistive material side of said structure,g) covering selected portions of said metal foil layer with photoresist on the side of said foil layer opposite resistive layer, andh) etching non-covered portions of said foil layer.
