Thin profile
Polyimide film heaters
Lightweight etched-foil heaters for tight clearances, rapid response, and clean bonding to flat or gently curved surfaces.
Sensing. Heating. Engineering.
Flexible Heating Solutions
CircuitSprint flexible heaters bring controlled surface heat to packs, housings, and assemblies where bulk heaters will not fit — without sacrificing uniformity or reliability.
- Polyimide film
- Silicone rubber
- Etched-foil circuits
- Custom outlines
01 Heater families
Two constructions. One engineering conversation.
Choose the dielectric and profile that match your temperature, moisture, and mounting constraints.
Ruggedised
Silicone rubber heaters
Conformable pads for moisture-prone or high-vibration environments, with options for wire leads, connectors, and thermal cutouts.
Custom geometry
Cutouts and multi-zone layouts
Irregular outlines, clearance windows, and independently controlled zones so heat follows the part — not a rectangular compromise.
Integration
Sensors and controls ready
Pair with CircuitSprint NTC or RTD sensing for closed-loop control, cold-start warm-up, and over-temperature protection schemes.
02 How we build
From thermal brief to production heater.
A clear path from application constraints to a heater you can mount, wire, and qualify.
-
STEP 01
Define the surface
Target temperature, watt density, substrate, and available thickness.
-
STEP 02
Layout the foil
Trace pattern, voltage, lead exit, and optional sensor pockets.
-
STEP 03
Prototype and tune
Sample builds for fit, rise time, and uniformity on your hardware.
-
STEP 04
Scale production
Repeatable tooling, labelling, and packaging for series builds.

04 Applications
Where flexible heat earns its keep
One short list — each use case needs heat on a surface that will not tolerate a bulky element.
- EV and ESS pack warm-up
- Medical and diagnostic plates
- Aerospace and avionics enclosures
- Lab and analytical instruments
- Camera and optics de-misting
- Industrial process fixtures
