White Horse Laboratories Week 22 Counterfeit Detection Report

White Horse Laboratories Week 22 Counterfeit Detection ReportWeek 22 Results

Inspection: 74% Accept Testing: 75% Pass

Following stabilizing in Week 21, Quality levels regained ground in Week 22. Electrical testing results improved from 65% in Week 21 to 75% in Week 22 and inspection acceptance rates climbed to 74% from Week 21′s 69% level.

Not surprisingly, shipping volumes improved a moderate 5% with the improved yields.

We saw five part numbers with a 100% failure in sample testing, indicating entire lots of devices that are not authentic or are non-functional. It is uncommon to see such high concentrations. Most rejected lots tend to be “mixed bags” of devices and several of Week 22′s 100% failures had mixed results, indicating the lot was comprised of multiple device types with none of them meeting the specifications of the required devices.

PMC Sierra HDMP1022G (Date Codes 0742 & 0951) – 36% failure – open, short pins and bad protection diodes.

PMC Sierra HDMP1024G (Date Code 0820) - 41% failure – open, short pins and bad protection diodes.

Ramtron FM1808-70PG (Date Code 1010) – 21% failure – program and verify error.

Infineon ITS716G (Date Codes 0928, 0930, 1002, 1004, 1010, and 1040) – 100% failure - output remained active at Vbb of less than 4.5V.

Fairchild FQPF10N60C (Date Code K46) – 100% failure – low BVdss.

Infineon KTY13-5 (Date Code 0609) – 100% failure – resistance consistent with KTY13-6 device.

Fairchild Semiconductor FHP3430IM14X (Date Code H5) – 100% failure - ustable output waves or no output on one or more channels.

API Delevant SDS680R-155M (Date Code not marked or labeled) – 100% failure – high DC resistance.
