    TERADYNE UNVEILS ADVANCED 3D X-RAY IMAGING TECHNOLOGY, CLEARVUE PROMISES TO INCREASE PCB FAULT COVERAGE AND REDUCE FALSE FAILURE CALLS

    -- Patented Off-Center Tomosynthesis technique delivers the industry's highest image resolution for 3D Automated X-Ray Inspection (AXI), produces best-in-class lead-free defect exposure and enables simplistic in-line automation.

    Teradyne, Inc., a leading manufacturer of high-performance board assembly test and inspection solutions, today announced an innovative breakthrough in 3D X-Ray imaging technology for detecting PCB (printed circuit board) solder and production defects. Paul Groome, manager of Teradyne's AXI products group, said, "The beauty of our ClearVue(TM) X-Ray technology lies in the increased quality, efficiency and simplicity it brings to Automated X-Ray Inspection. Both quality managers and production line controllers will benefit from its unique ability to identify material issues more quickly and with absolute certainty."
    Using a patented Off-Center Tomosynthesis imaging technique, the ClearVue X-Ray technology is ideally suited for densely packed single or double-sided boards that use BGA-style components and when loss of electrical or optical access is problematic. Compared to laminography and other 3D X-Ray techniques, ClearVue X-Ray technology's superior image clarity, diagnostic capabilities and full board coverage better exposes solder (including lead-free) flaws that are otherwise overlooked. More importantly, ClearVue X-Ray technology is expected to enable Teradyne to manufacture and sell the industry's highest fault coverage in-line X-Ray test and inspection solutions.
    ClearVue operates using a stationary X-Ray source and detector and, unlike conventional 3D X-Ray Test systems, does not require complex or rotating mechanical parts. The result is significantly lower false call rates (promising up to 40 times improvement over existing 3D X-Ray solutions); improved reliability, better repeatability and improved cycle times.
