BTU Int’l (www.btu.com) developed its Tritan Metallization Firing System for silicon photovoltaics. It includes TriSpeed technology that, according to BTU, enables aggressive temperature spikes without compromising drying, burnout, and cooling steps. Tritan’s three-belt system gives control of profile development, and its process chamber is designed to provide access from the top and bottom of the conveyor. Tritan is configurable to accommodate single- and dual-lane processing and can achieve 30- or 60-MW output on a single belt width. The system is controlled by BTU’s Windows-based, multilingual Wincon software with touchscreen GUI and can process 5 x 5-in. (125 x 125-mm), 6 x 6-in. (156 x 156-mm), and larger wafers. BTU says the furnace can be integrated with all mainstream printing/testing equipment.
