NORTH BILLERICA, Mass.—BTU International, a leading supplier of advanced thermal processing equipment for the alternative energy and electronics manufacturing markets, today announced the receipt of the largest single Pyramax order in company history from a leading semiconductor assembly and test subcontractor (SATS).

The multiple machine order, valued at nearly three million dollars, will be used to upgrade the customer’s existing installed base of advanced semiconductor packaging equipment. The machines are expected to ship in 2008, starting in the second quarter.

“We are pleased to receive this large follow-on order from a leading SATS customer,” said Paul J. van der Wansem, BTU International chairman and CEO. “The customer chose the Pyramax not only for its high performance—which makes it a perfect fit for advanced packaging—but for its industry leading Cost of Ownership advantage. The SATS market segment is forecasted to be one of the fastest growing areas in electronics assembly, and we expect to grow our market share in this key area.”

With 8 and 10-zone air or nitrogen models, 350 degrees Celsius maximum temperature, flexible platform configuration, low nitrogen and power consumption, and a comprehensive menu of options, the Pyramax provides optimized lead-free processing, maximizing productivity and efficiency. The Pyramax utilizes BTU's exclusive Closed Loop Convection Control to provide precise control of heating/cooling and the constant heat transfer that delivers maximum process control flexibility, assuring process repeatability from site to site and line to line. The system delivers proven features like side-to-side recirculation that enhances temperature uniformity, and unmatched convection efficiency that reduces zone temperature set points.
