Etched Foil Heaters for the Semiconductor & Wafers industries from Thermal Circuits.

In the early 1980's, Thermal Circuits introduced HTB etched foil element heaters to the Semiconductor industry to heat acid in portable wafer processing baths. It replaced hot plates that only heated from the bottom. The five-sided etched foil heater wraps the corresponding five-sided inner bath vessel with a combination of uniform and profiled heat. The etched foil heating process is designed to quickly bathe boatloads of wafers and other parts.

The etched foil elements are compatible with Thermal Circuits High Temperature Binder Inorganic and Organic coatings and with fabrication materials such as fiberglass cloth, fiberglass mat, mica, and ceramic fiber insulating carriers. The HTB coatings protect and immobilize the elements, yet allow them to expand and contract at watt densities two to three times greater with temperatures up to 1200° F.

The HTB etched foil heating construction is also used for wet processing equipment in-line heaters. Thermal circuits recommends electrical insulation depending upon the materials used in the customer's product, glass, plastic, coated or uncoated stainless steel. The use of quartz in the etched foil heater allows for a direct mount without insulation and is preferred by designers for high-wattage and high-temperature applications.

About Thermal Circuits:

Thermal Circuits Inc. is a manufacturer of surface heaters, air heaters, molded heaters, heater assemblies, and infrared panel emitters. We service a wide variety of markets and geographic areas and, through continuous quality improvement, strive to maintain world-class leadership in all aspects of our business.

Firsts" from Thermal Circuits continued during the 1970's and 1980's. We designed, prototyped and produced heaters and assemblies for the first etched foil-heated cafeteria food service stations, infant incubators, hospital warming cabinets, automobile side-view mirrors, kitchen electrics(mini-skillets, deep-fat fryers), and personal care appliances(mist hair setters, styling wands).

This growth prompted the construction in 1996 of a single-storied, 52,000 square foot building which is Thermal Circuits' new home. Still in Salem, the company is owned by its corporate partners and is the anchor company in a newly-developed industrial park. The new facility is state-of-the-art and second to none.
