Some methods for electronic component authenticity assessment

Abstract

The spurious aka counterfeit components represent still a serious danger for functionality, reliability and lifetime of any electronic device these components are part of its manufactured assembly. There exist a lot of methods aimed at revealing counterfeit components before they are used in electronic module production. Those methods differ in complexity and also in counterfeit component filtering yield. In short, any efficient method based on specification parameters manifestation, functionality and appearance comparison is applicable. This presentation illustrates the diagnostic abilities of some representative methods for counterfeit components preventive filtering from a production process. As a result of our research activities, the capability of popularly known Analogue Signature Analysis method is mentioned and illustrated as well as laser decapsulation method and a comparison of visual features accentuated with light exposure.
