Counterfeit components have become a multi-million dollar, yet undesirable, part of the electronics industry. The profitability of the counterfeit industry rests in large part to its ability to recognize supply constraints and quickly respond, effectively taking advantage of a complex and vulnerable supply chain. Events like product obsolescence, long life cycles, economic downturn and recovery, local disruptions in manufacturing due to natural disasters, and lack of proper IP legislation all represent opportunities for the counterfeit component industry to flourish. Electronic counterfeits affect every segment of the market, including consumer goods, networking and communications, medical, automotive, aerospace, and defense. At the manufacturing level, the use of undetected counterfeits leads to increased scrap rates, early field failures, and increased rework rates. While this presents a major problem impacting profitability, the use of counterfeit components in high reliability applications can have far more serious consequences with severe or lethal outcomes. For some time the weak link in the supply chain has been identified at the level of independent distributors. With the emergence of new legislation and through the efforts of different industry entities, new standards and guidelines are now available for suppliers to establish and maintain product traceability and to establish receiving inspection and detection protocols. There is no substitute for a healthy supply chain, and distributors play an essential role in the dynamics of the system. At the same time, there is an increased awareness of the need for proper management of electronic waste. Regardless of the nature of the counterfeits, whether cloned, skimmed, or re-branded, counterfeits are dangerous and too expensive to be ignored.The work presented here by the iNEMI Counterfeit Components-Assessment project group takes a more comprehensive view of the problem by surveying the possible points of entry in the supply chain and assessing the impact of counterfeit components on the industry at various points of use. We then propose a risk assessment matrix that can be used to reduce the risks for manufacturers.
By H A I X Y POWELL MILES, M. Inst. C.E.OSE of the many difticulties with which the railway maintenance engineer has to contend, in the efEcient and economical maintenance of the roads under his charge, is dealing with, and preventing as far as possible, the creeping or movement of the rails in a longitudinal direction. In recent years, owing to the increased volume of traffic and the greater weight and speed of, the trains, this difficulty has become more acute.The type of permanent way almost universally adopted in this country consists of bull-headed rails, supported in cast-iron chairs, held in position in the latter with timber keys, the cast-iron chairs being supported on, and fastened to, rectangular transvrrse sleepers. It is this type of permanent way with which the Antlror will deal, confining his remarks to the practical points of preventing :md dealing with the creep of the rails. The chief factors tending t,o produce the creep or movement, of the rails are :l . The driving-wheels of the locomotive hauling the train, when rotating, have a tendency to thrust back the rails in the opposite direction to the moving locomotive. The vehicles being hauled bythe engine have a tendency to pull the rails in the same direction as that in which the train is moving, due to the friction between the wheel and the rail, the flange of the former in particular when binding against the rail. 3. The weight of the moving vehicles on their wheels produces waves of deflection in the road, and has a tendency to roll out the rails in front of the vehicles.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
