NORTH READING, MASSACHUSETTS - July 27, 2001 - Teradyne announced a new, on-line interactive product experience module (PEM) to highlight its Optima 7000™ Series of Automated Optical Inspection Systems. Optima 7000 systems are used to locate defects -- and process variation that leads to defects -- for advanced OEM and EMS PCB assembly lines. The Teradyne interactive PEM focuses on operational and economic benefits of the Teradyne's Optima 7000 Series AOI systems, employing Java™ -based animations and comparative tools to highlight concepts and display the economic benefits that AOI offers to PCB manufacturers.

The Teradyne AOI PEM allows interested visitors to grasp Optima 7000™ operation, features and economics quickly, and to allow potential customers to make better informed decisions with more information than would be possible with a typical on-line document or printed brochure. The PEM integrates rich media demonstrations and interactivity with a compact, accessible information design to create a powerful, informative and entertaining experience that communicates the value of Teradyne's Optima to high-volume and high-mix PCB manufacturers.

Craig Pynn, manager, corporate marketing and chair of Teradyne's Web Steering Committee, commented, "We are constantly striving to provide a richer user experience at Teradyne's web site (www.teradyne.com) than one finds with typical 'brochure-ware.' The AOI PEM is an excellent means to provide more meaningful and useful content to our existing and potential customers."

The presentation explains in detail how technology trends, such as increasing component miniaturization, electrical complexity, loss of access at in-circuit test and growing PCB density have made AOI a timely tool for quality assurance and process control to augment widely used electrical test methods, such as in-circuit test. Manufacturers can learn how the speed, broad defect coverage and high reliability delivered by the Optima 7000 Series will benefit their current production test and inspection strategies, as well as accommodate future capacity growth.

Included in the PEM are several Excel™ -based analyses of AOI economics that allow production and test engineers to analyze the economic impact of AOI on their operations. The full PEM can be found at www.teradyne.com/aoidemo.
