Similarity approach for reducing qualification tests of electronic components

摘要

Qualification analysis and reliability testing of electronic components represent a major activity in the process of development of electronic equipment. Electronics manufacturers have to adopt often costly test programmes to ensure qualification standards and reliability requirements are met. This paper details a novel similarity-based qualification approach for assessing expected reliability of electronic components, and in general electronic products, as an alternative to conventional physical testing. The originality of this work is in the proposed approach which introduces a new way of qualifying electronic components based on similarity with previously assessed and qualified components. This novel approach has the potential to transform in a major way the current operational practices in the industry, demanding at present substantial physical testing, by offering a complementary, "virtual qualification" route for addressing the cost and time challenges associated with qualification tests.
