Optoi has embarked on a path of technological innovation for the past 10 years, which led them to be a reference point for the production of optoelectronic components in the European aerospace context.

By leveraging its know-how as a manufacturer of optoelectronic components for industrial encoders, in 2007 Optoi started collaboration with the French space agency CNES to create an 8-channel monolithic custom phototransistor for aerospace encoders. This development project was followed by others for the design of photodiode arrays and optical photo-couplers, in collaboration with the European Space Agency (ESA) and the Italian Space Agency (ASI).

In 2012, Optoi adapted its clean room to Class 1000 (according to FED STD 209E) or ISO 6 (according to UNI EN ISO 14644-1:2008), which is necessary for microelectronic assemblies intended for the aerospace market. In production, the reference standards are MIL-STD-883, MIL-STD-750 and the visual inspection ESCC Basic Specification No. 2045000 Standard.

These protocols require specific intermediate evaluation criteria to be applied during the assembly, the total absence of reprocessing, the measure of the degree of tightness of the component produced and a number of ageing tests intended to ensure the reliability of the component in operating conditions that can simulate an actual mission in orbit, thereby also including tests for the evaluation of radiation damage.

The activities carried out in the aerospace sector and the investments made in the production infrastructures have allowed Optoi to obtain significant improvements on the quality of all microelectronic products also for the industrial market.
