White Horse Laboratories Counterfeit Detection Report for Week 33

White Horse Laboratories Counterfeit Detection Report for Week 33Electrical testing yields recovered from Week 32′s deep drop and bounced back to 67%.

Six different devices had a high failure rate in Electrical Testing and three of those had a 100% failure rate.

Inspection results continued their sump by dipping to 33% in Week 33 (coincidence? I hope not) from 36% in Week 32. With over 60% of lots being physically substandard, the low electrical testing yields is not surprising.
