Failure analysis is the process of analysing the component data or the component itself to determine the reason(s) for degraded performance or catastrophic failure of a component either, during component manufacturing and testing, during incoming inspection, or after delivery to the customer, at the final application. Since there is an infinite number of variables in play at any one time, it is important as the first step in any failure analysis to understand how and when the failure occurred.

High thermal conductivity plastics filled with graphene have high thermal conductivity and good thermal stability, and their development prospects are very broad. Besides the thermal conductivity, graphene has other excellent properties, such as high strength, high electrical and optical properties, and is widely used in mobile devices, aerospace, and new energy batteries.

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.

The goal of passive components’ failure analysis (FA) is to determine the root cause for an electrical failure. The findings can be used by the manufacturers to improve upon the design, materials, and processes used to create their components. This leads to better quality and higher reliability components. The FA also provides feedback for the users to improve their handling, storage, and applications of these components.

Space standards (such as ESCC and MIL standards) have helped throughout the years to develop the industry and to achieve de mission goals. Standards improve the competitiveness, efficiency and knowledge transfer within space business. However, standards are not frozen documents, but rather they must change and adapt to the current requirements of the industry and the new developments and knowledge gathered during all the years of space missions.
