Week 8 Quality Report

Physical Inspection - 84% Accepted

Electrical Testing - 80% Passed

In the 8th week of 2011, White Horse facilitated USD133,015.00 in reliable component purchases.

Week 8 saw more stability in overall quality levels, with a slight increase in mechanical/visual and a decrease in electrical test results.

• Infineon BTS432E2, 17% failure (Date Code 0821) - no output current and failed switching.
• Vishay/Siliconix SFH6943-3, 100% failure (Date Code 0624) - high collector to emitter leakage, showing that they have a breakdown voltage below 70V.
• Texas Instruments OPA4130UA, 8.5% failure (Date Code 0930) - 6% with distored outputs, 2.5% with no output in one or more channels.
• STMicroelectronics BTA26-800B, 100% failure (Date Code 0922) - 4th quadrant gate-threshold current, Igt, and gate-threshold voltage, Vgt, with higher than specification readings, all other parameters passing.
• Dallas/Maxim DS1245W-11+, 40% failure (Date Code 1010) - program and verify error.
