Abstract: An electrically conductive multilayer film for providing an electrical path between two conductive surfaces includes a plastic backing layer, an electrically conductive layer disposed on a first side of the plastic backing layer, and a recovery layer disposed on an opposite second side of the plastic backing layer. An average thickness of the multilayer film is less than about 100 microns. A hollow gasket can be formed from the multilayer film by winding or bending the multilayer film into a flexible hollow closed loop. When the multilayer film is wound to form a flexible closed loop having an outside diameter of no more than about 7 mm with the conductive layer forming an outside layer of the loop, a resistance of the closed loop across a diameter of the closed loop remains less than about 2Ω when the loop is compressed across the diameter by at least 20%.

Abstract: A carrier tape for transporting a plurality of components includes a flexible substrate extending along a longitudinal axis of the carrier tape, a plurality of pockets formed in the substrate and spaced apart along the longitudinal axis of the carrier tape, and an adhesive layer. Each pocket includes a bottom wall and a side wall extending from the bottom wall to a top surface of the flexible substrate. The adhesive layer is disposed on the bottom wall of each pocket in the plurality of pockets, such that when a component is placed in a pocket in the plurality of pockets, the adhesive layer in the pocket permanently bonds to the component, and such that when the adhesive is exposed to UV radiation the adhesive bond strength is sufficiently reduced so that the component can be removed from the pocket.
