White Horse Laboratories' Quality Report

Work Week 21, 2011

Week 21 Analysis

Quality levels stabilized in Week 21 without dipping further from the plunge in Week 20, with testing lot pass rates staying at 65% and inspection acceptance rates creeping up a point to 69%.

Shipping volumes were down 43% from Week 20 following two consecutive weeks of poor yields. With Memorial Day in the United States, a public holiday in the United Kingdom on the same day, and a holiday throughout Europe on Thursday of Week 22, yield percentages will have larger individual influence due to decreased activity during a week loaded with international holidays.

With May winding down and heading into the final month of Q2, there is sure to be interest in market trends heading into what many are projecting to be solid business in Q3 and Q4 as the effects of reduced stock levels and limited production from the disruption of the Japan quake are expected to show their broader impact.

Holiday Notice

Dragon Boat Festival

Monday, June 6 - Dragon Boat Festival

Our Shenzhen laboratory and customer service facilities, and our Hong Kong facility will be closed on Monday, June 6, in observation of the Dragon Boat Festival. We will resume standard operations on Tuesday, June 7.

There are many legends about the origin of the dragon boat festival, all of which involve someone, from depressed government officials to ill-fated lovers, jumping into a river. People jumped into boats to race out to save the drowning martyr(s) and threw sacrificial rice dumplings into the river so that the fish wouldn't disturb the body, which have remained as the traditional celebration of the holiday.

It is one of the most exciting weekends in south China where colorful oared boats race in the bays and rivers with large crowds urging them on and pounding drums.

Weekly Quality Report Archives
Electronic Component Counterfeit Detection

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,

Mark A. Rinehart
