Temperature uniformity and accuracy come from Watlow's experience and ability to precisely pattern and distribute wattage of a thick film heater circuit and to maintain flatness requirements across a very large surface area. Thick film technology also gives designers the ability to zone heater circuits and reduce potential hot and cold spots resulting from boundary conditions.
They are compatible in vacuum applications to 10-6 millitorr, and the thick film heater circuit is designed with consistent part-to-part temperature uniformity. Thick film heaters are UL® recognized and can be applied in pre-heat, bake-out, annealing station applications as well as solar panel and color filter applications. This applied technology makes thick film heaters the ideal choices for large process tools.
