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.

For satellite applications where failure is not an option, electronic components need to operate constantly on demand, and have to be free of failures during the lifetime of the satellite-which can be for many years. To ensure this requirement is met, the components are put through many hours of stress testing covering all thermal.

X-ray photoemission spectroscopy (XPS) also known as electron spectroscopy for chemical analysis (ESCA) is a surface-sensitive quantitative analysis method to accurately determine the elemental composition of solid materials. The technique is the most extended tool for the chemical characterization of thin films coatings and surfaces either for industrial applications as well as for research

High reliability assembled PCB prototypes as well as novel surface mounted devices (SMD) and mixed systems must be assessed according to well defined qualification test plans. Such high reliability verification programmes are not limited to just evaluate the robustness, reliability and performance of the product but they also address the verification of tools, fabrication procedures and involved materials, as well as the confirmation of product integrity. For instance, ECSS (European Cooperation for Space Standardization” (ECSS) standards used in space programs
