White Horse Laboratories Counterfeit Detection Report Week 33
Physical condition results climbed from 50% in Week 32 to 54.2% in Week 33. A positive tick that we hope begins a trend. Electrical test yields, however, dipped to 70.8% following three straight weeks of improvement, peaking at nearly 79% in Week 32. Following the lower test yields, there are significantly more devices on the watch list this week.
