Research on Identifying and Avoiding Counterfeit Electronic Components

As the poor development of domestic semiconductor industry in China, the manufacturing of electronic equipments highly depends on the import of electronic components, especially monolithic integrated chips. Unfortunately, numerous counterfeit parts have been found in the supply chain because of the embargo, obsolete and other complicated reasons. Once these counterfeit electronic components were used, they can have devastating effects on the security and reliability of the electronic equipments. This paper analyses the reason of the emergence, source and types of counterfeit electronic components, and expound the method of identification and avoiding use of those counterfeit parts in the process of electronic equipments manufacturing, which is based on destructive physical analysis of electronic components and the database of basic characteristics information of imported electronic components.
