Electrothermal events. Electrothermal event refers to abnormal temperature increase leading to malfunction or catastrophic fails. The high temperature reached during such event activates or initiates some of the failure mechanism explained before, such as the growth of insulation oxide layers and outgassing processes responsible for organic contamination. Besides the formation of nonconductive layers at the contact interface, high temperature can also cause to the degradation of plastic insulators and contribute to multiple short circuit conditions.

Red Plague is problematic corrosion appearing on silver-plated copper conductors. An electromechanical reaction is induced between copper core and silver plating of the conductor (by means of moisture and oxygen present in the silver-copper interface). Wire affected by Red Plague is mechanically compromised, increasing the failure risk linked to severe vibration and shock conditions on space flight.
