TERADYNE INC.’S ASSEMBLY TEST DIVISION has upgraded its Design-to-Build (D2B) Software to version 3.0, featuring an enhanced version of D2B Strategist, its distributed test management software. D2B provides distributed test management across multiple test and inspection platforms, such as automated optical inspection, automated X-ray inspection, flying probe and in-circuit test platforms. Principal upgrades include accurate predictability of test time and test yields; feedback from Teradyne test and inspection platforms that verifies fault coverage; calculation and analysis of test strategy effectiveness in catching defects; and D2B/ECO, a completely new module that can compare two revisions of a PCB assembly by performing checks to see if components have been added, removed or modified.
