Week 19 Analysis 

 

Physical Inspection acceptance rates climbed again in Week 19 to 85% from Week 18's 67%, a high for the year. Electrical testing results dipped a point to 79% on record volume for the year, up 98% from the previous week.

 

This marks the fifth straight week of a general upward trajectory in product quality. This is consistent with what we have seen as a trend in the market - buyers becoming more knoweldgeable of the measures and methods required to identify substandard and counterfeit electronics, and the penalties becoming more severe for delivering those products to an end-user.

  
In my opinion, the highest risk devices are still both passive and active discrete devices, such as capacitors and transistors.

Greetings! 

  
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.
  
We are now providing you with access to historical reports through the archives available on our website. Note we do not list individual companies. We consider all test and inspection reports to be confidential to the requestor and White Horse is not authorized to disclose and distribute that information.
Notes:

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.

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

 

All the best,
