Flexible heaters are single layer flexible circuits that utilized resistive alloys, such as Inconel and Cupro-nickel, rather than copper to form conductive paths. As electrical current is driven through the higher resistance conductors, heat is generated. Conductor width and thickness are selected to provide the desired resistance value based on the supply voltage.

Flexible heaters offer very good heat transfer to the heat sink in a very low profile and low mass package. Because they are flexible, they can also conform to, and heat, irregular surfaces that other types of heaters cannot. TCR (Temperature Coefficient of Resistance) of custom heater alloys provide minimum resistance change when temperature changes.
