Use and benefits of COTS board level testing for radiation hardness assurance

New Radiation Hardness Assurance (RHA) approaches to insert commercial-of-the-shelf (COTS) electronics into space systems are studied. This study is based on analyses and board level radiation testing of a carefully selected COTS electronic board with a wide range of key commercial components to identify failure modes. A cost-effective qualification approach based on an iterative workflow is proposed. Use and benefits of this method are discussed.
