The ESA (European Space Agency) named this satellite as Aeolus, coming from Greek mythology, Eolo (in Greek), is known as the father of the race eolia, the lord and god of the winds. What is intended with this satellite is to gather accurate information about the winds, not achieved so far. Becoming the first satellite to do it directly from space and collecting the necessary information to understand how the winds, atmospheric pressure, temperature and humidity are related, in a layer of 30,000 meters from the surface of the Earth.

Depending on the intended application electrical components are exposed to either transitory or permanent dynamic mechanical stress which can impair the performance (e.g. mechanically induced crack in PCBs systems or fretting corrosion in connectors and others).

How can failures in vibration tests be avoided?

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.
