Life test is an electrical stress test that typically employs voltage and/or temperature to accelerate the appearance of wear-out reliability failures in a device. The objective of life testing is to evaluate whether failures caused by wear-out are likely to occur during the product lifetime and thus to estimate compliance of the device with the long-term reliability requirements
UL94 flammability test that are referred by number of manufacturers using plastic materials such as moulding packages? Omnexus, the material selection platform for plastic material by SpecialChem provides an overview of the test in details.
The Silicon Carbide power diodes were specifically designed for protection of solar cells arrays in solar panels mounted in satellites and space exploration modules. The first batches of devices are currently used for two European Space Agency missions, BepiColombo and Solar Orbiter.
The general specification for hybrid microcircuits (MIL-PRF-38534) details the qualification and testing requirements for non-hermetic packages for military and space applications, and the MIL-PRF-38535 proposed class Y monolithic microcircuits for non-hermetic space level.
The paper describes the activities and results of an ESA-funded project concerned with the assessment of optical amplifier technologies and products for applications in fiber optic subsystems of future satellite payloads. Onboard applications are briefly introduced, together with associated system-level requirements. Optical amplifier technologies, research achievements and products are reviewed.
Propose a DD test standard
• Should be available by the end of the year after ESA and Components
Technology Board (CTB)/Radiation Working group (RWG) comments
• Goal of this presentation
⇒ Not a draft of the future guidelines, but:
• Remind the physical processes responsible of the displacement damages
• Remind the electrical effects
• List the main parameters that should be taken into account
The different DD level may be obtained by different particles.
Proton is preferred. The energy of proton should be selected based on the proton energy spectrum inside of the spacecraft.
Neutron may give underestimate test results.
TID and DDD should be tested on the same group samples.
The new CERN High energy AcceleRator Mixed Field facility (CHARM) allows to test several single components, as well as more complex devices, at different locations, characterized by particle spectra representative of the high- and low-altitude atmospheric, particle accelerator and ground environments.
