What Alter Technology does

Alter Technology (legal entity ALTER TECHNOLOGY TÜV NORD S.A.U.) is a Spain-based high-reliability electronics services provider headquartered in Seville, operating as a wholly-owned subsidiary of the TÜV NORD GROUP within its Digital & Semiconductor business unit alongside TÜVIT. Founded in 1986 as TECNOLOGICA in Madrid before relocating headquarters to Seville in 1993, the company has grown through six European acquisitions (HIREX Engineering France in 2001, IGG Components UK in 2006, TOPREL Italy in 2007, OPTOCAP in 2016, and HTV Germany in 2023) into a 700+ employee, 11-location group spanning Spain, France, the UK, Germany, the United States (Minnesota), Taiwan, and Korea.

The company delivers end-to-end semiconductor and equipment services across three core areas: semiconductor services (design, engineering, OSAT including wafer probing, assembly, packaging, reliability and radiation testing, EEE parts procurement, and 50-year long-term conservation); equipment testing and conformity (environmental, EMC, radio spectrum, electrical safety, functional, drones, and calibration in an ESA-accredited Space Test Centre); and management system certification (quality, environment, cybersecurity, automotive, and energy audits). Specialized technology platforms include the HEOP-HyViS radiation-tolerant hybrid visible image sensor (SiPDA + ROIC), GaN-on-Diamond RF power transistors (THRUST project), co-packaged optical transceivers (CAPTIVATE), and photonic integrated circuit packaging for quantum and space applications. ESA, ECSS, ENAC, DAkkS, EN 9100, ISO 27001, and ITAR accreditations underpin a regulatory moat.

Commercially, Alter operates a professional services model with custom quotation per project, monetizing testing capacity, engineering hours, accredited certification, and long-term managed storage. Revenue is generated through direct enterprise sales to space, aerospace, defense, automotive, medical, and telecommunications primes (named customers include ESA, GMV, Airbus, and Space Asics), supplemented by EU, ESA, CDTI, Innovate UK, and ERDF co-funded R&D consortium work. The combination of mission-critical accreditation, TÜV NORD distribution reach, and a deep EU-funded innovation pipeline positions the company as a strategically embedded European supplier to high-reliability electronics supply chains.
