5.2 Environmental Reliability Testing
5.2.1 Structural Reliability Testing
Structural reliability tests consist of unpackaged, system -level vibration and shock
tests of a given thermal solution in the assembled state. The thermal solution should
meet the specified thermal performance targets after these tests are conducted;
however, the test conditions outlined here may differ from your own system
requirements.
5.2.1.1 Random Vibration Test Procedure
Recommended performance requirement for a system:
• Duration: 10 min/axis, 3 axes
• Frequency Range: 5 Hz to 500 Hz
5 Hz @ .001 g2/Hz to 20 Hz @ 0.01 g2/Hz (slope up)
20 Hz to 500 Hz @ 0.01 g2/Hz (flat)
• Power Spectral Density (PSD) Profile: 2.2 G RMS

5.2.1.2 Shock Test Procedure
Recommended performance requirement for a system:
• Quantity: 2 drops for + and - directions in each of 3 perpendicular axes (i.e., total
12 drops).
• Profile: 25 G trapezoidal waveform
225 in/sec minimum velocity change. (systems > 20 lbm)
250 in/sec minimum velocity change. (systems < 20 lbm)
• Setup: Mount sample system on tester.
