White Horse Laboratories Week 49 Quality Report
Physical Inspection – 64% Accept
In Week 49, White Horse facilitated USD155,385.00 in successful transactions!
Starting in Week 49, we have begun to include the date codes of the tested devices. Week 49 saw a recover in both testing and inspection quality levels, with a resultant increase in shipment volume. Again, the highest percentage of non-functional devices are in the discrete, both active and passive, categories.
Be on the lookout, though, for the following high risk devices*:
ON Semiconductor UC2843BD1R2G, 35% failure (date codes 0639, 0640, and 1015) - no gate drive output.
ON Semiconductor 1SMA5919BT3G, 100% failure (date code 029) – high zener voltage, Vz.
Vicor V48B3V3C150L, 51% failure (no date code on label or marked on the devices) – high output voltage.
Infineon BTS133, 100% failure (date code 0936) – high on-state drain-to-source resistance, Rds(on).
Murata GRM188R61A475KE15D, 84% failure (date code 1024) – high dissipation factory, DF.
AVX CB027D0104JBA, 7% failure (date code printed as 09+) – high dissipation factor and low capacitance.
* Note: high risk is defined as devices with over a 5% failure rate in electrical testing.
Quality drives a company’s reputation, its bottom line and above all, its value.
