Week 11 Quality Report

Physical Inspection - 76% Accepted

Electrical Testing - 56% Passed

In the 11th week of 2011, White Horse facilitated USD189,054.00 in reliable component purchases.

Week 11 saw another decrease in electrical testing pass rates with an improvement in physical condition of the devices with another gain in volume coming through the lab. Only a week after the devastation in Japan and interruption in power and we already saw high risk devices from manufacturers such as Fuji and Panasonic.

• Fuji 2SK902, 12% failure (Date Code not marked or labeled) - high gate-source saturation current, Igss, above +/-1uA with +/-20V gate-source voltage .
• Ramtron FM24C16A-G, 8% failure (Date Codes 0935 and 0939) - program and verify errors.
• Linear Technology LT1308BCF, 46% failure (Date Code 0536) - very low reference and output voltage.
