Datasheet Specifications Accessory Kit

The Dunegan 4501 has been designed to detect loose particles in electronic components - programmable to provide speedy and precise automatic testing in accordance with MIL-STD-883C Method 2020 for hybrids and MIL-STD 750C Method 2052.
 

Features:

  • A flexible microprocessor-based controller with simple keyboard entry of all test parameters
  • A specially designed shaker to shock and vibrate the device under test
  • An oscilloscope for visual monitoring of signals created by loose particle impacts
  • A speaker for audio monitoring of signals created by loose particle impacts
  • Intensified oscilloscope display during threshold detector output
  • An indicator lamp that lights each time a particle impact is detected
  • An indicator lamp that lights and remains lit after a particle impact signal exceeds the failure threshold level
  • Numerical display of measured shock and vibration amplitudes
  • Numerical display of programmed frequency and other test parameters
  • Automatic frequency calculation from test package cavity height per MIL-STD 883C Method 2020 requirements
  • Abort function will stop the test on the first detection of a particle impact
  • Keyboard lock with a fixed, code number program entry key prevents inadvertent alteration of the test program
  • Test sequence program maintained in memory by battery power during primary power failure or equipment power off
  • Overriding manual operation when desired
  • Super low noise level for detecting micro-particles
  • Simplified Sensitivity Test Unit (STU) checkout method that meets MIL-STD 883C Method 2020 and MIL-STD 750C Method 2052
