There is NO alternative to good supply chain management as a defense against counterfeit parts. Many types of products that have to be manufactured and supported for long periods of time lack control over critical parts of their supply chain, e.g., avionics and space, telecom infrastructure, and industrial controls. As a result, the components and technologies that these products depend on become obsolete long before the product’s field life (and sometimes manufacturing life) ends. One of the reasons of companies becoming victim of counterfeit electronics is lack of planning for obsolescence and making distress purchase from unauthorized sources. Guidelines based on DMSMS plans that include obsolescence and design refresh planning, supplier approval processes, auditing and contractual requirements will be discussed.

Much of the problem regarding counterfeit electronics is due to lack of due diligence by the part buyers. Understanding of the supply chain and assessing the supply chain before engaging them are necessary steps for any organization. This part of the course will cover how to understand and utilize process change notices for making supply change management and counterfeit detection more efficient. The role of counterfeit part reporting as a legal and technical tool along with its promises and limitations will be discussed with examples. Impact of the US DoD rule changes on the supply chain will be introduced. Authentication tools such as tagging, dye pigments, forensic markers and barcodes will also be discussed as a method of supply chain management.

    For an electronics equipment manufacturer, it is difficult to identify counterfeit parts among the thousands of parts used daily, unless there is a sustained and deliberate attempt to verify the parts. The AS6171 Aerospace Standard (currently in draft) standardizes the test and inspection procedures, workmanship criteria, and minimum training and certification requirements to detect counterfeit electrical, electronic, and electromechanical parts. The standard comes in response to a significant and increasing volume of counterfeit EEE parts entering the supply chain. The standard is designed for adoption by aerospace and military manufacturers and contractors, providing uniform requirements, practices and methods to mitigate the risk of receiving and installing counterfeit electronic parts. The Standard ensures consistency across the supply chain for test techniques and requirements based on assessed risk of the application, component, supplier, and other relevant risk factors.

    This full day, combined lecture and hands-on workshop being offered at the Symposium on Counterfeit Parts and Materials, 2015, begins with a brief introduction to the electronic parts supply chain, the sources of authorized and unauthorized parts and overview of the diverse counterfeit part creation techniques. The tools, techniques and procedures for the non-destructive, destructive and analytical technique that are part of AS6171 will be discussed. Also included are discussions of minimum level of inspection, sampling plan based on tier level of accepted risk, and reject criteria.

    One session of the workshop will be devoted to laboratory demonstration of relevant equipment used for counterfeit parts identification and inspection. Equipment such as x-ray, x-ray fluorescence, optical inspection, solvent testing, acoustic microscopy, electrical tests and other pertinent techniques. Attendees will also get an overview of the certification and training requirements for each AS6171 inspection technique. In the end, authentication tools (such as DNA marking, dye pigments and barcodes) will be discussed.
