Thick Film Heater Resistors
TSEC designs and manufactures application-specific thick film heater resistors.
Heater resistors apply a controlled level of heat to a specific area. Typical applications include laboratory and medical fluid heating, condensation management, and anti-freezing in electronic equipment.
Why Thick Film Resistor Technology?
Once installed a heater resistor component can be difficult to access, replace or repair. Therefore, It must be mechanically robust, electrically stable and deliver a long in-service life despite exposure to regular temperature cycles.
Thick film technology delivers high watt density (amount of heat energy emanating from a given surface area), excellent heat transfer, thermal efficiency and temperature uniformity across a surface.
Thick film heater resistor components can be shaped to deliver heat to a point contact. They can be custom-designed to fit in areas that are difficult to access.
Thick Film Heater Resistor Design
Heater resistor design challenges include:
- Thermal efficiency.
- Watt density.
- Speed of response
Current flow through a resistor material produces a proportional heating effect. The challenge is to transfer this heat to the surrounding area (or point contact). This is defined as thermal efficiency.
A common solution is to use a thick film resistor pattern on substrates with excellent thermal conductivity. Substrate materials include specialist steels, stainless steel and aluminium.
TSEC has extensive experience of the performance and reliability demands of heater resistor applications. We work closely with customers through the custom heater resistor design and manufacturing phase. A selection of prototypes can be delivered if required.
