White Horse Laboratories Weeks 9-10 Counterfeit Detection Report

White Horse Laboratories Weeks 9-10 Counterfeit Detection ReportElectrical Testing yields reached their highest point of 2013 by hitting 94% in Week 9 before falling back to a more modest 76% in Week 10. Both weeks had holiday-influenced volume reductions around the Lunar New Year holiday.

There was a wide range of devices with high failure rates, including discrete, linear, memory, and ASIC (application-specific integrated circuit) devices.

Inspection yields made progress in Weeks 9 and 10 after crashing to 50% in Week 7. Week 8 scratched up to 58% in Week 9 and then reached 75% in Week 10. Let’s hope that is the beginning of a trend.

Inspection Accept 67%  Electrical Testing Pass 86%
