Week 49 Quality Report

Electrical Testing
- 82% Pass
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.
