White Horse Laboratories: Week 41 Quality Report
Electrical Testing – 84% Pass
Physical Inspection – 50% Accept
Week 41 saw a higher percentage of substandard devices rejected following physical analysis, reducing the number of unacceptable devices making it to electrical testing.
Be on the lookout for the following high risk devices*:
Texas Instruments TLC279ID, 6% failure – no ouput signal and low output swing.
International Rectifier IRG4PC5UD, 5% failure – low breakdown voltage, V(br)ces, and high gate-source junction current, Iges.
Analog Devices ADSP2185KSTZ133, 5% failure - open pins.
Texas Instruments SN65ALS1176DR, 18% failure - low receiver high ouput voltage and high receiver low output voltage.
Texas Instruments NE5532ADR, 36% failure - no output at one channel or both of two two channels.
Analog Devices AD8627AKSZ-REEL7, 12% failure – clamped output voltage indicating an open output.
Analog Devices AD1139K, 40% failure – low ouput voltage when writing program.
Analog Devices AD1139J, 17% failure – static output voltage when writing any program.
* 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.
