KING YUAN ELECTRONICS COMPANY (KYEC) QUALIFIES
ELECTROGLAS EG6000 300MM WAFER PROBER
SAN JOSE, CALIF.—September 26, 2006—Electroglas, Inc. (Nasdaq:EGLS), a leading supplier of wafer probers for the semiconductor industry, today announced that KYEC, Hsin Chu, Taiwan, has qualified the Electroglas EG6000 for production probing of 300mm wafers on the first of a multi‐ATE tester platform evaluation. This decision followed an extended production trial and was based upon the superior technology, performance, and cost of ownership of the EG6000. Mark Chou, Director, Logic and Mx CP Division, KYEC, said, “The EG6000 has met all expectations and was quickly qualified for production use during the first phase of an extensive multi‐ATE tester platform evaluation. We are extremely pleased with the production results from the EG6000 and thus the immediate production qualification of the tool on the first of several ATE platforms used at KYEC. Given the results of the extended evaluation on the initial ATE tool set, we anticipate that the EG6000 will advance through the remaining tester platforms with similar results.” Tom Rohrs, Chairman and CEO, Electroglas said: “KYEC is a global leader in wafer test of mixed signal, logic and memory testing and we are pleased that this production trial has confirmed that our exclusive 300mm technology provides significant benefits to the most advanced customers in the wafer testing sector. We look forward to working closely with KYEC to qualify on additional ATE platforms.” - more -
