White Horse Laboratories: Week 40 Quality Report
Electrical Testing – 55% Pass
Physical Inspection – 71% Accept
Week 40 saw failures in a variety of device categories, rather than the predominantly discrete (passive and active) that we had been seeing in previous weeks.
Be on the lookout for the following high risk devices*:
Atmel AT45DB161D-TU, 27% failure – erase, program, and verify errors.
Atmel ATMEGA1281V-8MU, 36% failure – ID and blank check errors.
ON Semiconductor NTB60N06T4G, 100% failure – low power handling capability.
STMicroelectronics VNH3ASP30-E, 9% failure – wrong output state and high supply current at no load.
Maxim MAX6192AESA+, 40% failure - high and low output voltages (mixed bag).
Analog Devices AD1139J, 17% failure - static output voltage when writing any data.
Infineon BTS3142D, 6% failure – mixed parametric failures (mixed bag).
* 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.
