    Methods
Screening tests are standard for all MIL-PRF-55310 products. Q-Tech will customize screening and test procedures to meet your specific requirements.
  1. INTERNAL VISUAL per MIL-STD-883, Method 2017 and 2032
  2. STABILIZATION BAKE (Prior to Seal) per MIL-STD-883, Method 1008, Condition C (150ºC)
  3. TEMPERATURE CYCLING per MIL-STD-883, Method 1010, Condition B (-55ºC to 125ºC)
  4. CONSTANT ACCELERATION per MIL-STD-883, Method 2001, Condition A (Y1 Axis only, 5000g)
  5. FINE LEAK per MIL-STD-883, Method 1014, Condition A
  6. GROSS LEAK per MIL-STD-883, Method 1014, Condition C
  7. PRE BURN-IN Electrical Test, Output Frequency and Waveform at nominal supply voltage, Specified Load, +23ºC ±1ºC (OPTIONAL)
  8. BURN-IN (Load) Energized oscillator, with nominal supply voltage and burn-in load, is tested at 125ºC for 160 hours min.
  9. FINAL ELECTRICAL TEST: Input Current Power, Output Frequency, Output Waveform, and Output Voltage Power are tested
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.

GROUP A

  1. ELECTRICAL TEST: Supply Voltage, Input Current, Output Waveform, Output Voltage Power, Rise and Fall Times, Duty Cycle, and Start-Up Time (as required)
  2. FREQUENCY-TEMPERATURE STABILITY: Initial Accuracy at Reference Temperature, Initial Frequency-Temperature Accuracy and Frequency-Temperature Tolerance
  3. FREQUENCY-VOLTAGE TOLERANCE: Output Frequency is measured when oscillator supply voltage is adjusted to its specified nominal value up to its maximum / minimum values
  4. OVERVOLTAGE SURVIVABILITY: Overvoltage of 20% above the maximum specified
  5. VISUAL AND MECHANICAL: Verify Material, Design, Construction, Workmanship, Physical Dimensions, and Marking per MIL-PRF-55310
  6. SOLDERABILITY TEST per MIL-STD-202, Method 208

GROUP B

  1. 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
Every 24 months, a Group C Inspection on MIL-PRF-55310 products is performed. The test data is reviewed and approved by DSCC. This data becomes generic test data which is available for the customer upon request.

GROUP C

  1. VIBRATION (Sinusoidal) non-operating per MIL-STD-202, Method 204, per MIL-PRF-55310
  2. SHOCK (Specified Pulse) per MIL-STD-202, Method 213 (non-operating)
  3. THERMAL SHOCK per MIL-STD-202, Method 107
  4. AMBIENT PRESSURE (operating and non-operating) per MIL-STD-202, Method 105, and MIL-PRF-55310
  5. STORAGE TEMPERATURE per MIL-PRF-55310
  6. RESISTANCE TO SOLDERING HEAT per MIL-STD-202, Method 210
  7. MOISTURE RESISTANCE per MIL-STD-202, Method 106
  8. SALT SPRAY per MIL-STD-883, Method 1009
  9. TERMINAL STRENGTH per MIL-STD-202, Method 211
  10. RESISTANCE TO SOLVENTS per MIL-STD-202, Method 215
