This paper will present the assessment of automotive qualified components for Space applications being performed in the frame of ESA Contract 4000126343/19/NL/hh. The proposed work to be performed includes a full thermomechanical and endurance evaluation (2000h life test, 500 cycles -55ºC to +125ºC thermal cycling, HAST or THB) along with constructional analysis and measurements of Tg (glass transition temperature) and outgassing. These tests will be done on three different lots separated by years of lot date codes on three selected AEC-Q candidates (total 9 lots). This testing will allow to confirm manufacturing stability (die mask, assembly techniques, moulding material, etc….) and process variability over time. The three candidates are selected from non-radiation sensitive devices of an “AEC Space PPL” List already compiled from the comparison of what is offered as AEC qualified (AEC QPL list with >200K items) and what is more demanded for Space (Space PPL list from ESCC QPL/QML/PPL, NASA NPSL/GSFC PPL, etc.. with 1500 items).
The space community has long resisted the use of COTS due to inherent risks and uncertainties in the process, including lot traceability, validity of radiation test results, test program correlation, and lack of manufacturer warranty and support.
Analog Devices has established three commercial space product screening and qualification flows to address New Space needs, designed to offer the best price/reliability ratio for applications targetting different requirements
Produced and tested on the same line as Q-tech most stringent space qualified oscillators, the parts proposed for LEO applications, QT780 SERIES, QT723 SERIES, QT735 SERIES are made with the same Q-Tech quality and reliability
Eutelsat interest in COTS digital components mainly resides in the possibility to drastically increase processing capabilities while maintain SWaP performance at an affordable level for a commercial GEO Satellite mission.
Whatever the communication mission, whatever the frequency band and associated coverages, the digital processing will bring important benefits in terms of being able to flexibly allocate the spacecraft resource to respond to evolutions of the market needs.
Additionally, more generic payload “building blocks” will permit to lower the procurement time while permitting to decrease industrial cost associated to manufacturing, test, integration on satellite, ranging from one-time programming on ground to full SDR (Software Defined Radio) architectures with full on-board reprogramming!
