ABSTRACT:
A thick-film electric heater having thick-film layers applied directly on a thermally conductive non-flat substrate. Preferably, the substrate is cylindrically shaped. A dielectric layer is silk-screened on the substrate surface. A resistive layer is silk-screened on the dielectric layer to form a circuit for the generation of heat. The resistive layer has at least one resistive trace in a pattern that is discontinuous circumferentially. At least a pair of silk-screened contact pads are applied in electrical communication with the resistive layer for electrical connection to a power source. An insulation layer is applied over the resistive layer.
