White Horse Laboratories Weeks 29-30 Counterfeit Detection Report

White Horse Laboratories Weeks 29-30 Counterfeit Detection ReportElectrical Testing yields suffered a dizzying drop to 49% in Week 29, from 79% in Week 28, and then recovered back to 79% in Week 30, averaging just 58% for the period, down significantly from 74% in the previous period.

Ten different devices had a high failure rate in Electrical Testing, only one of which was a 100% failure rate.

Inspection results logged their third straight week of incremental gains, edging up to 49% acceptance rate for the period. Compared to the previous period, it is a significant improvement, but bear in mind that Week 28 posted a low of 32% and less than half of inspected devices being in acceptable condition is exceptionally poor.

Still, three consecutive weeks of improvement, regardless of how incremental they may be, is hopefully the beginning of an improvement trend.
