Counterfeit electronic components entering into critical infrastructure and applications through the global supply chain threaten the economy and national security. In response to the growing threat from counterfeits, the Society of Automotive Engineers G-19 Committee is developing AS6171. This aerospace standard is focused on testing facilities with a goal of standardizing the process of counterfeit detection. An integral part of the standard is a semi-quantitative risk assessment method. This method assigns risk scores to electronic components based on a number of relevant criteria, and places the components into one of five risk tier levels corresponding to an appropriate level of laboratory testing to ensure the authenticity of the component. In this way, the methodology aims at standardizing the risk assessment process and bases the identified risk as guidance for commensurate testing protocols. This paper outlines the risk assessment method contained within AS6171 and briefly explores other complementary efforts and research gaps within the G-19 and electronics community.

Through the years there has been a significant and increasing volume of fraudulent and counterfeit electronic parts entering the aerospace supply chain. Left undetected, these parts can pose significant performance, reliability, and safety risks. In response to these threats, the SAE AS6081 Counterfeit Electronic Parts Avoidance – Distributors standard was developed to provide uniform requirements, practices, and methods to mitigate the risk of electronics distributors purchasing and supplying these counterfeit electronic parts throughout the aerospace supply chain. This course will begin with a one-hour, pre-recorded session that covers background information on the proliferation of counterfeit electronics. Made available prior to the start of the live sessions, the on demand recording will also discuss the development of a consensus standard for the procurement, detection, reporting, and disposition of these parts. Through the series of five, live sessions, the instructor will guide participants through a comprehensive overview of the requirements of AS6081, including detailed information on the certification scheme and implementation strategies.

Plastic - any class of synthetically-produced organic compounds capable of being molded and hardened into a specific shape or form. This course is designed to offer a basic understanding of plastics and plastic processing. Using plastics can be simple, but there is much more behind producing high performance plastic parts. This seminar will walk you through the molding process, provide a comprehensive look at the variables in the manufacturing mix, and review characteristics of typical automotive plastics such as PP, PVC, ABS, and more. This seminar will also cover troubleshooting molding mistakes and alternative processes, and review the selection of an application's appropriate plastic material. Material presented is both an excellent foundation for further development and an extensive update for those already working in the field.

One of the main advantages of the precision forging process is the reduction in material consumption due to the achievement of close tolerances and the reduction of machining requirements to meet final component specifications. However, to achieve these results comes at a cost. One of the primary issues with precision forgingis the reduction in life of the tools used in the forming process. Manufacturers can mitigate some of these concerns by better understanding how tools can be designed specifically for the precision forging process and how personnel can effectively apply precision forging techniques. This two day seminar will introduce participants to tooling design practices that can be successfully applied to precision forging methods. The instructor will guide participants through critical die design requirements to optimize die life. Participants will be provided detailed information related to inspection and calibration techniques and requirements. The instructor will then provide participants the requirements of an effective quality control system, including the rigorous requirements for aerospace and medical parts manufacturing.

SHM is defined as “the process of acquiring and analyzing data from on-board sensors to evaluate the health of a structure.” (SAE-ARP6461). It is clear that large wind turbine blades, and particularly offshore systems, may benefit from a fully automated surveillance procedure for continuous monitoring of peak structural loads, and early damage detection, with considerable savings in maintenance. This presentation reviews the basic concepts to implement a SHM system on a large composite structure (sensor selection and embedability issues, algorithms for data processing, system considerations). Examples of current usage are given.

As ever-decreasing project timelines meet ever-increasing budget constraints, the importance of accurate design verification through composites prototyping becomes ever more critical. Traditional methods that rely heavily on machined metal molds and autoclave-processed pre-preg materials can maximize time and budgetary constraints, while providing higher performance than is necessary from a typical secondary structure. This presentation will provide an overview of several composites prototyping techniques that can be directly applied to non-critical, secondary structures while providing aerospace-grade results to assist in the timely and cost-effective verification of advanced composite designs.
