The aeronautics sector requires an ever-higher standard of quality and reliability for its embedded technologies.

SERMA Technologies provides its technological expertise in embedded electronic systems by ensuring the reliability of components and electronic systems.

Our expertise in assisting with problem-solving for components, circuit boards and electronic systems, in supporting design and industrialisation, and in managing and handling obsolescence has been recognised by the aeronautics sector for many years. We monitor manufacturing processes for components, circuit boards and materials used through verification programmes for PCBAs and PCBs, and site audits.

SERMA addresses the specific needs of the procurement chain for a component by performing each stage from design to supply of an ASIC, by performing assembly and a customised test, or by qualifying COTS plastic components.
