BTU International to Present at SMTA Upper Midwest

NORTH BILLERICA, Mass., May 27, 2010—BTU International (Nasdaq: BTUI), a leading supplier of advanced thermal processing equipment to the alternative energy and electronics manufacturing markets, today announced that Rob DiMatteo, Regional Sales Manager, will present a paper titled “Reducing Reflow Costs in a Challenging Economy” at the upcoming SMTA Upper Midwest Expo and Tech Forum. The presentation is scheduled to take place on Wednesday, June 9, 2010 at the Sheraton Bloomington Hotel in Bloomington, MN.

When budgets tighten, engineers are challenged to find ways to reduce manufacturing costs. Although the focus in an SMT process is typically on identifying less expensive materials and reducing scrap, the efficient operation of a reflow oven is often overlooked.

The presentation will highlight methods that can be used to lower energy costs of a reflow oven while maintaining profiles that are within the solder manufacturer’s specifications.

Rob DiMatteo is a Regional Sales Manager with BTU International in North Billerica, MA. He has over 18 years of extensive experience in surface mount assembly, customer support and product development. DiMatteo is the author of many published articles and has presented at numerous technical seminars and conferences around the world.
