Abstract
An adhesive copper strip is provided with an opaque covering on the adhesive side thereof. The opaque covering may be provided in one of two ways. In one embodiment, a coating of black acrylic or epoxy is applied to the copper strip beneath the adhesive layer. In a second embodiment, the adhesive contains carbon particles dispersed uniformly throughout the adhesive in sufficient quantity to render the adhesive opaque.
