Materials & Electrical Components Laboratory
What is its role?
Made up of more than 20 dedicated experimental facilities and hundreds of instruments overall, ESA’s Materials & Electrical Components Laboratory guarantees an optimal choice of electrical components, materials and processes for ESA missions and external projects, considering the unique environmental challenges involved in building for space, additionally investigating failures to ensure similar issues do not occur on future missions.
The Lab provides to Europe’s space community the facilities and expertise to investigate the effects of the environment on electrical components, materials and processes in support of advanced research and development, evaluation and qualification programmes and direct project support. In the materials domain support is provided on topics such as metallic materials, polymers, ceramics, composites as well as their associated manufacturing processes, such as curing, bonding, coatings, welding, surface mount techniques as well as cleanliness and contamination effects In the electrical components domain this encompasses all aspects of reliability analysis, failure analysis and radiation effects characterisation.
