Custom Heating Systems

Good thermal design depends on more than a rated power value. Warm-up time and steady-state control can need different power levels. A pi heater uses thin polyimide film around a patterned resistive heating circuit. It also shows where simple checks can prevent costly redesigns. The aim is steady heat without making the assembly harder to build. Its low mass can help the surface warm quickly. Support the leads so they do not pull on the heater. Power should match th
