A pad including thermal insulation and heat sink areas. The pad includes a plurality of layers of metal foil forming a stack with the layers arranged one above the other, the stack including at least one heat sink area and at least one insulating area adjacent to the heat sink area, the layers providing better heat conduction in the vertical direction at the heat sink area than at the insulating area. At least one of the layers includes a plurality of embossments therein separating the one layer from an adjacent one of the layers in the insulating area. The pad can include a single insulating area surrounded by a heat sink area and a black coating can be provided on selected portions of the layers to improve heat radiating characteristics of the pad. For instance, the heat sink area can be coated with the black coating to radiate heat away from the pad at a desired location. The pad is particularly useful in shielding a heat sensitive component on one side of the pad from a heat source on the other side of the pad. The pad can be covered with a prescored and/or embossed metal sheet coated on one or both sides with adhesive. The sheet can also be used by itself for fixturing. The sheet can be secured to an object by heating to cause the adhesive to adhere to the object. The prescoring can be perforations in the sheet and the embossments can be in a diamond shaped cross-hatching configuration.

[ What is claimed is:] [1.] A pad including at least one compressed portion forming a heat sink area and at least one thermal insulating area, comprising:a plurality of interior layers of metal foil between a top layer and a bottom layer of metal foil forming a stack wherein said layers are arranged one above another in said at least one compressed portion forming the heat sink area and in said at least one thermal insulating area, at least one of said layers including plurality of embossments therein separating said at least one of said layers from an adjacent one of said layers in said at least one insulating area so as to provide a gap therebetween, the layers being secured together by securing means at said at least one compressed portion of the stack, one of the layers in said at least one insulating area being adjacent to and not metallurgically bonded to another one of the layers in said at least one insulating area.
