A laminate contains conductive circuit patterns, a substrate material, and an adhesive pattern or other bond. Each conductive circuit pattern and the substrate material are interconnected by the adhesive pattern or other bond, having its size and shape substantially matching the main outlines of each conductive circuit pattern. Each conductive circuit pattern has thin lines and thin interline spaces, patterned on top of the adhesive pattern or other bond by a removal of conductive material, such that the circuit pattern's thin interline spaces may have residues of the adhesive patterns or other bond. Outside the conductive circuit patterns' main outlines, the substrate material is substantially void of an adhesive or other bond, with the exception of edge areas of the main outlines.
