How a PI Heater Fits Curved and Irregular Heating Surfaces
A good heating design starts with the job, not the heater alone. Heat loss, contact pressure, and airflow all change the result. A pi heater uses thin polyimide film around a patterned resistive heating circuit. The goal is a setup that is easy to build and control. The aim is steady heat without making the assembly harder to build. Its low mass can help the surface warm quickly. Press from one side to the other to limit trapped air. Bend radius should protect the f
