Abstract
A layered heater includes a resistive layer formed from a conductive material and separated into an intermediate area and a resistive circuit pattern by a plurality of cuts that extend all the way through the resistive layer. The resistive circuit pattern includes termination pads electrically connected to the resistive circuit pattern with the intermediate area being electrically inactive. A conductive overlay is disposed over a continuous portion of the resistive circuit pattern. The plurality of cuts extend longitudinally into the conductive overlay such that no portion of the resistive pattern is present outside the conductive overlay.
