“Vibration analysis is performed to identify defects or drifts in electronic equipment across various stages of its life. Vibration test systems are first employed to detect latent defects and faults in electrical, electromechanical, electronic and mechanical hardware at the manufacturing stage,” according to Importance of Vibration Testing for Electronic Equipment by Sam Jacob Thomas.
NJMET uses vibration analysis as part of our PIND (Particle Impact Noise Detection) testing to determine the authenticity of electronic components. We have recently discovered dangerous counterfeit components in two separate customer orders using PIND testing.

PIND is just one process in NJMET’s Mission Imposter® Counterfeit Component Testing Program. Mission Imposter is a rigorous set of tests to determine the authenticity of electronic components.
