As it has been mentioned in “Vibration Test on Hi-Rel for EEE Parts”, vibration tests are important to check the reliability of the components/assemblies. These tests can be a headache and suppose a great cost if the design of the device and the fixing tool are not properly done. Simulation tools are the key to anticipate to the problems reducing costs and lead times.

The purpose of vibration tests is to evaluate the effect caused on component parts by vibration in a specified frequency range. The samples are subjected to testing under different conditions, as described below, in accordance with the respective applicable standards. The test conditions differ in terms of duration, frequency range, vibration waveform, amplitude, etc.
