NORTH READING, Mass. – May 18, 2008 – Teradyne, Inc. (NYSE:TER) announced the milestone shipment of the 2,000th test system from its Nextest® business unit, located in San Jose, CA. A major Korean-based flash manufacturer, and long-term customer of Teradyne, accepted a Magnum™ SSV for production testing of their high-density NAND flash devices. Typical applications for these device types include memory cards, mobile phones, PDAs and many other consumer digital products.

“This significant milestone underscores the success of Magnum and its ability to provide customers with compelling test solutions from engineering through the critically important high-volume production process,” said Tim Moriarty, general manager of the Nextest business unit.

The 2000th milestone shipment includes both the Magnum and Maverick® series test systems. Maverick, originally designed to address the requirements for higher parallelism, throughput and lower cost of test, was first shipped in 1998. The architecture proved to be so successful that it continued on to the next generation test platform, Magnum. By utilizing current high-density technologies, Magnum was able to deliver the same robust architecture to customers at half the price-per-pin, and today continues to provide even greater efficiencies for cost-sensitive device manufacturers and subcontractors worldwide.

Through Magnum’s flexible architecture, systems can be configured from 128 pins up to 7680 pins. Magnum’s stackable architecture allows customers the convenience and flexibility to add pins, as needed, for future production requirements. And, because all pins are contained in 8 identical chassis—spares, maintenance and upgradeability are simplified and less expensive for manufacturing and service.
