QUALITY CONFORMACE INSPECTIONS (QCI)
Quality Conformance Inspections (QCI) are standard for all MIL-PRF-55310 products. Sample units are tested in accordance with Group A and Group B requirements for inspection lots.
For space level products, Q-Tech offers Screening and Quality Conformance testing in accordance with - or superior to - MIL-PRF-55310 and MIL-PRF-38534. Our application note describing the differences in these requirements can be found here.
GROUP A
- ELECTRICAL TEST: Supply Voltage, Input Current, Output Waveform, Output Voltage Power, Rise and Fall Times, Duty Cycle, and Start-Up Time (as required)
- FREQUENCY-TEMPERATURE STABILITY: Initial Accuracy at Reference Temperature, Initial Frequency-Temperature Accuracy and Frequency-Temperature Tolerance
- FREQUENCY-VOLTAGE TOLERANCE: Output Frequency is measured when oscillator supply voltage is adjusted to its specified nominal value up to its maximum / minimum values
- OVERVOLTAGE SURVIVABILITY: Overvoltage of 20% above the maximum specified
- VISUAL AND MECHANICAL: Verify Material, Design, Construction, Workmanship, Physical Dimensions, and Marking per MIL-PRF-55310
- SOLDERABILITY TEST: per MIL-STD-202, Method 208
GROUP B
- AGING TEST: Oscillator is energized in oven for a continuous period of 30 days at 70ºC ±3ºC. The Output frequency is measured within an interval of 72 hours maximum per MIL-PRF-55310
