White Horse Laboratories Week 16 Quality Report
Since 2009, White Horse has been publishing Weekly Quality Reports. These reports contain lists of part numbers with high electrical failure rates that should be considered high risk. Within these reports, you can also spot trends for overall product quality in the market, industry volume trends, and you can drill into the manufacturers and part numbers to identify highest risk component categories and OCMs.
Inspection: 59% Accept 52% Pass
1. Statistics are calculated as a percentage of all lots dispositioned 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.
