Structural Reliability Testing
Structural reliability tests consist of unpackaged, board-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.
