About ALTER Technology

ALTER Technology provides laboratory and engineering services for high-reliability Electrical, Electronic, and Electromechanical (EEE) components and equipment for space and harsh environments. The company specializes in microelectronics and optoelectronics engineering, procurement, assembly, and testing. Its services include parts engineering, logistics support, electronic design, radiation verification testing (TID, DD; SEE), electrical measurements at various temperatures, screening, qualification, destructive physical analysis (DPA), constructional analysis, failure analysis, and full characterization of electronic components at wafer, component, and system levels. They also focus on photonics for technologies such as electro-optical devices, cryogenic and space vacuum systems, image sensors, and optical communication systems. ALTER Technology serves customers in space, aerospace, defense, medical, and automotive sectors, including space equipment manufacturers and institutions like the European Space Agency (ESA). The company's journey began with TECNOLOGICA in Spain in 1986, followed by acquisitions in France, the UK, and Italy. Since 2011, it has been integrated within the TÜV NORD GROUP. Facilities are located across Spain, France, Germany, and the UK, totaling 8,500 m² of laboratories. They have been involved in projects such as ADM-AEOLUS, BEPI Colombo, Galileo, Meteosat, Juice, Ariel, and LISA. The company holds certifications and accreditations including ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, and ISO/IEC 17025:2017, and is ENAC accredited for testing and compliance services. They have been audited by organizations such as ESA, CNES, and DLA.
