2、feit Components Abstract: The increasing world trade in counterfeit electronic components poses a significant risk that a potentially mission-critical component procured for use in a flight system may be counterfeit, and it is often difficult to determine whether a part is bogus. This lesson learned
3、 suggests a set of awareness, prevention, detection, and response strategies that may help mitigate the risk of counterfeit electronic parts being used in flight hardware or other critical equipment.Description of Driving Event: Reference (1) describes the pervasive and increasing problem of counter
4、feit electronic components and the countermeasures being employed by the Jet Propulsion Laboratory (JPL) and the aerospace industry. According to the JPL article, counterfeit parts include: a71 Components with original component manufacturer (OCM) markings that were stolen and are being sold without
5、 testing. a71 Dummy components with no die or wires inside, but marked as authentic. (Figure 1). a71 Scrap stolen from the manufacturer, but marked as good product and sold at the normal price. a71 Re-branded parts from a low-quality manufacturer, marked with the logo of a high-quality manufacturer
6、and sold at a premium price. a71 Recycled component sold as new. a71 Blacktopped and re-marked integrated circuit (IC) (Figure 2), with a: a72 Newer date code, a72 Bogus part number, a72 Commercial part re-marked as up-rated or up-screened without any assessment or testing, or a72 Recycled, reclaime
7、d, pulled, or salvaged piece part marked as new.a71 Obsolete product pulled from stock of old boards and sold as new. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-Figure 1 is an X-ray, a shadowy grayscale image, of a rectangular package with 4 lea
8、ds extending from the top and 4 leads extending from the bottom. Within the rectangular package itself, there are no features visible at all no wires or subcomponents. The package appears to be empty.Figure 2 is a close-up photo of the portion of a piece part that contains product markings. (Because
9、 it is a close-up shot, it is not clear what type of part it is, but the blocky outline and the visible contacts suggest an integrated circuit.) Visible on the part is the manufacturers logo and a portion of three lines of product identification characters. However, a quadrant of the product identif
10、ication characters have been removed by erasure, revealing a logo of another manufacturer that lies beneath the characters.Figure 1.

11、d overprinted with the markings of another manufacturer.Counterfeit goods represent approximately 5 to 7 percent of world trade; since 1982, the value of bogus goods traded globally has increased from $5.5 billion to approximately $600 billion annually (Reference (2). Several factors contribute to t
12、he targeting of the electronic component market by counterfeiters: a71 Device obsolescence has caused an increase in the scarcity and price of critical components used in military and civil aerospace systems. a71 The flow of information through internet product search engines (IPSEs) facilitates fin
13、ding obsolete or hard-to-find devices, and obtaining delivery overnight or within a few days. But internet purchases may provide no traceability or complex part sourcing history, minimal warranties, and no certainty of replacements or refunds. a71 With the increasing sophistication and complexity of
14、 component technology, it may be more difficult to detect fakes. Testing of incoming items has decreased over the years, resulting in a reliance on the suppliers Certificate of Compliance as proof of authenticity and compliance. a71 Unauthorized gray market channels for legitimate products can facil
15、itate distribution by counterfeiters. Gray market distributors cannot determine whether a high volume influx of a product is a counterfeit or a legitimate OCM product that has been redirected from the source. a71 Subcontract assemblers and manufacturers may not report suspect devices in order to pro
16、tect their reputation for quality. The best practice for obtaining legitimate electronic components designated for flight hardware is to buy them directly from OCMs (first-tier suppliers) or their authorized distributors (second-tier suppliers). Because this option may require the purchase of large
17、quantities (minimum buys) or long lead times, projects may resort to independent distributors (i.e., gray market third-tier suppliers) for non-flight hardware- breadboards, prototypes and engineering models. For schedule or cost-constrained projects, the rapid delivery of smaller quantities may offs
18、et the risk from limited or missing component traceability data. However, purchase from a third-tier supplier will increase the risk of receiving counterfeits, and it may not be feasible to mitigate this risk if the engineering model is later upgraded to a flight unit. JPL has formed a working group
19、, with representation from the procurement, quality assurance, parts engineering, and technical infrastructure organizations, to address and mitigate the threat of counterfeit electronic components populating hardware assemblies. An action plan based on current industry best practices includes the J
