White Horse Laboratories Counterfeit Detection Report and 2012 First Quarter Quality Report

White Horse Laboratories Counterfeit Detection Report and 2012 First Quarter Quality ReportFirst Quarter 2012 Summary

In our 2011 Summary, we discussed a decrease in physical acceptance rate and wondered whether that might be a reflection of growing buyer caution with the heightened awareness of counterfeit electronics components, or whether it is a direct reflection of the quality of the devices themselves.

In the first quarter of 2012, we saw an average lot acceptance rate of 63% compared to 68% in 2011 and 69% in 2009. Is this 5% drop in the first quarter a realistic reflection of the quality of the devices inspected? We have enhanced our database, including tracking the percentage of devices by condition classification in addition to other key statistics.

We will also be focussing our Weekly Poll Questions towards industry perception regarding inspection related issues, starting with our first poll of 2012.

What is your opinion about the effects of increase counterfeit awareness and legislation? Post your vote on this week’s poll at  http://conta.cc/IaQoNd.

We’ll post the results here, in our monthly newsletter, on our website, and our new Twitter page, @whitehorselabs.
