Abstract
A layered heater system is provided that includes an engineered substrate having an upper face sheet, a lower face sheet, and a core disposed between the upper face sheet and the lower face sheet. A dielectric layer is formed on at least one of the upper face sheet and the lower face sheet, a resistive element layer is formed on the dielectric layer, a protective layer is formed on the resistive element layer, and terminal pads are formed over at least a portion of the resistive element layer, wherein the terminal pads are exposed through the protective layer. In one form, the core defines a honeycomb structure, and in another, the core defines a frame structure having a plurality of support ribs.
