Week 10 Summary

Week 10 saw the return of fairly normal operations as the supply chain got back into motion following the holiday break, and the weekly statistics are more valid with regular volumes.

That being said, we saw the first plunge of the year for Electrical Testing yields, falling to 42% in Week 10 after climbing in Weeks 2-9 to 100%. Inspection yields; however, recovered to 78% in Week 10 after falling to just 33% in Week 9, just the second but also the lowest, rating in the young year.

Seven part numbers have been added to the Substandard Parts List this week, two of which had a 100% failure rate (which were submitted for Failure Analysis).

Notes:

1. Statistics are calculated as a percentage of all lots dis-positioned within the given time period.

2. "Accept" is defined as customer acceptance of report device condition.

3. "Pass" is defined as meeting electrical parameters defined by the agreed upon test plan.

We hope you find this report informative and usefull for your organization.
