Week 18 Summary                                                                        

 

Electrical Testing yields and Inspection yields both improved in Week 18.

 

Testing yields remained at climbed forward to 74% in Week 18 after three weeks of hovering around 70%. The suspect list therefore fell to six devices having a failure rate of over 5%, one of which were 100%.

 

Inspection yields also pushed forward to 76% in Week 18, making a third consecutive week of improvement.

ES Live 2014 - The Data Behind the Report
Thursday, May 15 - Milton Keynes, United Kingdom

The past decade has seen product verification being a rarity to it becoming the norm. Does product testing, though, confirm acceptable product quality?
 
This workshop will help guide you through the minefield of interpreting, and verifying, product reports to take charge of your product verification program and make informed decisions.

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.
