Production Applications for IR Furnaces

APPLICATION	DESCRIPTION	FURNACE SOLUTIONS
Hybrid Thick Film Firing Thick film firing of nobel metals Glass annealing Thick Film	The industry was revolutionized by the develpoment of the first fast-fire thick film firing furnace in the early 80's. Today IR furnaces still provide the fastest heat up and cool down times.	TF Series furnaces can heat up to 1000°C and stabilize in less than 10 minutes. When it is time to change profile or shut down, they can cool down to 400°C in less than 10 minutes. TF-Series Furnaces

The AG Series Furnace was designed specifically to provide precise profiles and atmospheres for silver-glass die atttach. Ideal for processes requiring multi-stage temperature profiles and rapid removal of volatiles. AG-Series Furnaces The S-Series High-Temperature furnace can be equipped with a sophisticated hydrogen package for flip chip wafer bumping. S-Series Furnaces S-Series Hydrogen
Drying IR / Convection curing Drying Polymer Solutions Drying Polymer Coatings Polyester Paint Films Infrared Curing Heat Sensitive substrates Cure Powder Coatings Food drying Chemical drying Thin film curing	Infrared dryers engage transfer of both mass and energy. Heat is transferred from the IR emitters by both radiant and convection means into the polymer solution and causes evaporation of the solvent. As infrared thermal energy is emitted from lamps above the polymer-substrate, the solvent absorbs the IR radiation triggering vibrations of its molecules and a subsequent transfer of mass and heat. Flowing air introduced through the chamber walls exits through the exhaust stack carrying away the water vapor and solvent vapor.	D-Series IR Dryers precisely control temperatures to 200°C and higher along with control of process gas flow to assure removal of moisure and released solvents. D-Series IR Dryers
