Counterfeits have been reported in a wide range of products, including computers, telecommunications equipment, automobiles, avionics and military systems. Counterfeit electronic products can include everything from very inexpensive surface mount capacitors and resistors to expensive microprocessors. Unfortunately, the counterfeit EEE component problem is growing rapidly with no signs of abatement are in sight. The tutorial begins with an introduction to electronic parts supply chain, the sources of authorized and unauthorized parts. Attendees will learn about the status of the electronic part distribution market and how it has changed over the past decade. The movement of the manufacturing and technology know-how across the globe will be covered to understand the international aspect of the counterfeit electronics supply chain. This part is followed by information on the extent of the counterfeit electronics problem with illustrative examples that emphasize the aspects of supply chain. The tutorial further covers the tools and techniques that engineers need to understand for determining the risk levels of components that require authentication. Basic inspection and electrical testing will be covered with an emphasis on the tools and techniques necessary for positive identification of parts that are not authentic in their representation. Attendees will also learn how to effectively engage specialist electrical and material testing laboratories in a cost effective manner to determine risk of counterfeit components.
