Abstract
Abstract A conductive connection between a metallized outer surface of a film of plastics material, such as a polyimide film and a metal or metallized surface of a substrate to which the film is attached. The connection comprises a flexible conductor secured to the substrate and a second film of plastics material which is bonded to the metallized surface of the first film material and to the flexible conductor to effect a conductive connection between the metallized surface of the first film and the substrate. The second film may be so arranged that it holds the flexible conductor in close contact with the metallized layer on the first film to effect an electrical connection but is preferably metallized whereby an additional electrical connection is effected by way of its metallized surface and the flexible conductor.
