PI Heater Design Factors for Better Temperature Uniformity
Reliable heating begins with a clear view of the part and process. The full assembly matters more than any single heater feature. A pi heater uses thin polyimide film around a patterned resistive heating circuit. You can use these points during design, sourcing, and testing. The aim is steady heat without making the assembly harder to build. The flexible form suits many custom layouts. Bolts and brackets can act as local heat sinks. Bend radius should protect the fi
