         Business Fuels Sequential Revenue and Earnings Growth


    NORTH BILLERICA, Mass.--(BUSINESS WIRE)--Oct. 23, 2007--BTU
International, Inc. (Nasdaq: BTUI), a leading supplier of advanced
thermal processing equipment for the electronics manufacturing and
alternative energy markets, today announced its financial results for
the third quarter ended September 30, 2007.

    Net sales for the third quarter were $16.5 million, compared to
$13.8 million in the preceding quarter, and compared to $18.3 million
for the third quarter of 2006. Net income for the 2007 third quarter
was $0.5 million, or $0.06 per diluted share, compared to net income
of $0.2 million, or $0.02 per diluted share reported in the preceding
quarter, and compared to net income of $2.3 million, or $0.25 per
diluted share, in the third quarter of 2006.

    Net sales for the first nine months were $45.5 million compared to
$61.7 million for the first nine months of 2006. Net income for the
nine months ended September 30, 2007 was $1.4 million, or $0.15 per
diluted share, compared to a net income of $8.2 million, or $0.87 per
diluted share, for the first nine months of 2006.

    Commenting on the company's performance, Paul J. van der Wansem,
chairman and CEO, said, "In line with our guidance, results for the
third quarter were up significantly as compared to the preceding
quarter. Both the electronics and alternative energy sectors
demonstrated growth, with the largest growth rate seen in the
energy-related portion of our business."

    Outlook

    "We expect that our efforts related to the alternative energy
market will allow us to rapidly increase market share in this sector,"
said van der Wansem. "Our team has developed and introduced several
new products designed to help our customers drive down the cost per
watt of energy production. The company participates in many rapidly
growing alternative energy applications, including silicon-based solar
cells, thin-film solar and nuclear fuel, as well as solid oxide fuel
cells.

    "Looking forward to the fourth quarter, we expect continuing
growth based on a strengthening backlog in our energy business, and
business from the electronics sector comparable to the third quarter.
Fourth quarter revenues are expected to increase, compared to the
third quarter, by approximately 10 percent, with earnings up by
approximately 60 percent."
