Silicone Rubber Heaters

Silicon Rubber flexible heaters are typically used when the application calls for a higher temperature. They consist of a “single” conductive layer and two silicon rubber insulating layers. These circuits have an overall thickness range of 60 (.060”) to 67 (.067”) mils typically. That makes them the least flexible heater construction by definition, however they can reach normal operating temperatures up to 250C. Any components required for these design types must be embedded between the insulating layers. That includes temperature sensing components as well as power hook up wires.

Some Key Points

  • Simple and robust construction well suited for applications small and large

  • Wide operating temperature range from ‐55°C ‐ 250°C
  • Mount all necessary component types
  • Meets IPC‐6013 Qualifications and Performance Specifications for Flexible Printed Boards
