GuideTech Expansion Attracts Semiconductor Industry Talent

Adds New Board Member and VP Finance/Administration

Sunnyvale, CA – June 26, 2006 – GuideTech, leading provider of precision timing solutions that break semiconductor test cost barriers, announces the addition of a new board member – Frank McKiney of ADR Test Systems, formerly of Form Factor and Agilent. In addition, Andrew Dunn (formerly of Check Point Software Technologies and Hitachi Data Systems) has joined the company as VP Finance and Administration.

"GuideTech is growing rapidly as more and more customers recognize our products as a great alternative to wholesale tester upgrades and adopt our easily integrated solutions as the most cost-effective way to address high-speed test challenges like PLLs and high-speed serial interfaces on existing or low-cost ATE," stated Bob Raybuck, GuideTech President and CEO.  "As we grow, we are adding key elements to our management team to ensure we have the expertise and experience needed to stay ahead of the curve.  Frank and Andrew with their industry knowledge and contacts are important additions in that regard and we are very excited to have them on board."

About GuideTech
GuideTech is the leading innovator in high-performance CTIA-based timing measurement instruments, providing semiconductor manufacturers with the solution they need to minimize timing-related component failure and to dramatically reduce production test costs through test-time reduction and extended ATE lifecycles. Based on patented Continuous Time Interval Analyzer (CTIA) technology, the company's FEMTO 2000 and GT4000 families of multi-channel timing test systems and accompanying Datacom Analysis software substantially improve test throughput via fast measurement rates, far greater measurement and analysis accuracy, and the ability to handle asynchronous or non-deterministic signals without external arming on up to 32 or 64 channels. These capabilities, which are strongly linked to GuideTech’s unique CTIA technology, enable critical, high-speed, functional, timing and jitter test coverage for PLLs and multi-gigabit serial interfaces such as PCI Express and Serial ATA, in milliseconds, in parallel, and in production. Headquartered in Sunnyvale, CA, the company is the first to deliver cost-effective, advanced timing measurement solutions that easily integrate onto any ATE platform.
