Thick Film Heaters
Heatron uses the latest thick film materials to formulate dielectric, conductive and resistive elements for producing high performance thick film heaters, resistors, and other circuit elements on insulated steel, stainless steel, and ceramic substrates.
Our proprietary Elpor® system is used to electrically insulate metal substrates. The thick film resistive elements provide very fast temperature response and uniformity in low-profile heaters. Thick film heaters are ideal for applications where space is limited, where conventional heaters cannot be used, when heat output needs to be profiled across the surface, or in high watt-density applications.

What is thick film?
The term “thick film” relates to conductive, resistive, or dielectric circuit elements that are deposited via screen printing materials (~0.0005″ thick) onto the substrate. Thick film technology was originally found in hybrid circuits for military and automotive applications where performance, durability and high reliability were essential.
Thick film inks are made by mixing ceramics and metals (known as cermets) are used to make the resistors and conductors. Typically the metallic materials are silver, gold, platinum, palladium, ruthenium and related alloys. Glass-ceramic inks are also used for dielectrics between encapsulants covering the circuit layers. Cermet thick film materials and substrates vary, based on the specific application requirements.
