BOSTON--(BUSINESS WIRE)--Dec. 8, 2004--Teradyne, Inc. (NYSE:TER) announced King Yuan Electronics Co., LTD (KYEC), Taiwan's largest IC test house by revenue, has purchased multiple Handler Interface Board (HIB) Changers for use on their installed base of FLEX™ test systems. A Teradyne-patented design, the HIB Changer is a mechanical interface between the handler and test system that reduces operator set-up time, enabling improved operating efficiency. Often called "Operational Equipment Efficiency" (OEE), this is a significant metric that test subcontractors and other operators of test equipment are driven to improve. The HIB Changer from Teradyne provides a substantial advancement in this area, particularly where there is a high changeover rate of device types being tested.

"By making these automation upgrades with the HIB Changer, we expect a reduction in changeover time to improve our OEE," said Mr. Stone Chen, Director, Logic & Mixed FT Division, KYEC. "In the subcontract business, improving efficiency is a major factor in equipment productivity. Delivering a solution to improve OEE, is consistent with Teradyne's commitment to deliver a lower cost of test."

"We're excited to be delivering to the industry the HIB Changer as it offers our customers a significant improvement in package test production," said Kim Abplanalp, Product Manager, Teradyne's Production Integration group. "The key is to minimize test cell changeover time between production runs. Our innovative approach reduces the HIB change from a 15-minute operation requiring 2 people, to a one-person process completed in less than 5 minutes. We're delighted that KYEC has joined the growing customer list now using Teradyne's HIB changer."
