False top coatings of a counterfeit component revealed layer by layer

摘要

Much has been written about the curse of counterfeit electronic components having such a compounding effect on the security and economy of the United States. This paper will demonstrate one of the techniques used by those responsible for polluting the open market inventories of the world with counterfeit components. This sample of a counterfeit component and the photos shown are examples of a real inspection rejection event that successfully detected what could have been a tragic failure in an aerospace, military or mission critical system somewhere in the world. It is the intent of this paper to share the knowledge and experience it took to detect this counterfeit component, with the hope that every organization may benefit from this information.
