Exhibit 99.1

SMTC Amends Debt Agreements

Lowers Interest Rate, Extends Term and Improves Repayment Schedule

TORONTO, May 19, 2010 - SMTC Corporation (Nasdaq: SMTX, TSE: SMX), a global electronics manufacturing services provider, today announced it has signed amended loan agreements with Wells Fargo Capital Finance Corporation (formerly Wachovia Finance Corporation) and Export Development Canada to refinance the Corporation’s short and long term debt.

Under the new lending arrangements, the term and principal repayment schedule have been extended to 2013 and virtually all principal payments eliminated in 2010. With the performance and prospects for the Company continuing to improve, interest rates have been reduced and covenants either eliminated or modified. Interest rates on the revolving line of credit are now at prime rate plus 1%, currently representing an aggregate rate of 3.25% in Canada and 4.25% in the US; reducing to prime rate as performance improves. Interest rates on the term loan will also vary depending upon financial performance in the range of LIBOR plus 2.5% to 3.5% (currently 2.8% to 3.8% in aggregate).

“This refinancing is part of SMTC’s overall strategy for growth by providing both greater financial flexibility as well as lowering annual interest expense by $350,000 at today’s debt levels. We expect to further reduce interest costs through continuing debt reduction,” stated Jane Todd Senior Vice President Finance and Chief Financial Officer. “The refinancing also is a testament of the strong relationship between the company and its lenders, Wells Fargo and Export Development Canada, both continuing to be strong supporters of SMTC.”
