Abstract
A method of forming a layered heater assembly includes: forming a plurality of layers onto a substrate, the plurality of layers including a resistive element layer; forming electrical terminations in contact with the resistive element layer; securing a protective cover over the layers using a laser welding process, wherein edges of the protective cover are welded circumferentially around raised end portions of the substrate and welded longitudinally along a slotted portion of the substrate; securing a pair of lead wires to the electrical terminations; and securing a lead cap assembly around the pair of lead wires and to the protective cover using a laser welding process.
