BTU International Reports Fourth Quarter and Fiscal Year 2006 Results

          2006 - Net Income Doubles - Sales up by 18 Percent


    NORTH BILLERICA, Mass.--(BUSINESS WIRE)--Feb. 20, 2007--BTU
International, Inc. (Nasdaq NM: BTUI), a leading supplier of advanced
thermal processing equipment for the electronics manufacturing and
alternative energy generation markets, today announced its financial
results for the fourth quarter and fiscal year ended December 31,
2006.

    Net sales for the year 2006 increased to $78.3 million, up 18
percent compared to $66.4 million for the year 2005. Net income for
2006 was up 100 percent at $9.2 million, or $0.98 per diluted share,
compared to a net income of $4.6 million, or $0.60 per share for 2005.

    Fourth quarter net sales were $16.6 million, down 9 percent
compared to $18.3 million in the preceding quarter, and down 14
percent compared to $19.3 million for the same quarter a year ago. Net
income for the fourth quarter of 2006 was $1.0 million, or $0.11 per
diluted share, compared to a net income of $2.3 million, or $0.25 per
diluted share, in the preceding quarter, and compared to a net income
of $2.1 million, or $0.25 per diluted share, in the fourth quarter of
2005.

    Commenting on the Company's performance, Paul J. van der Wansem,
Chairman and CEO, said, "In the first half of 2006 our business in
equipment for electronics assembly was very strong, however, this was
followed by a persistent slowdown in the second half. The alternative
energy business was up, driven by a substantial increase in the solar
energy segment. Overall, we are pleased with the significant progress
made and the Company's ability to leverage its business model -
improving product margins, increasing investment in new product
development and continuing on a profitable course despite the recent
downturn."

    Outlook

    "Based upon our current knowledge, we expect the business level
and results for the first quarter of 2007 to be similar with those of
the last quarter of 2006," said Van der Wansem. "Industry forecasts
indicate further growth in the demand for electronics, which is likely
to drive an improvement in future orders for capital equipment for
semi-packaging and PC board assembly applications. In addition we are
focusing on the solar and nuclear energy markets as significant growth
opportunities for 2007 and beyond. The Company anticipates doubling
its alternative energy business this year."
