Integrating Thin-Film Sensors into Polyimide Heaters

Having discrete sensors and heaters can complicate thermal management. In ideal configurations, a heater heats a heat sink and a sensor attaches to the sink in order to regulate temperature. But with a heater attached directly to a heat sink’s surface, it may be challenging to find a good location to attach the sensor.

The solution involves integrating the sensor beneath the heater’s polyimide cover, which allows the assembly to not only heat the sink but also press the sensor against it for the most accurate reading possible.

Minco’s latest white paper explores the advantages of this technique but also reasons why it might not be the best option for your project.

In this free whitepaper, we share:

  • How integrating sensors and heaters makes for more accurate temperature measurement
  • How this technique simplifies wiring and installation
  • How integration actually saves money through simplified installation and superior cost of ownership
