It is to be noted that the polymeric package -- though making it technically unsuitable for agency-rated space applications due to its lack of hermeticity -- is built in order to endure a extended ranges of thermal and mechanical loads. Notably, the package is filled with a gel, supposed to damp excessive vibration and shocks, hence protecting the silicon subsystems and metallic wire-bondings from fracture. This feature made it unbreakable during the vibration test campaign of the previous study. This has also been demonstrated during the present study, even with the devices having been through a first step of thermal testing.
