This paper reports work from a major UK research project which seeks to develop a cost effective integrated production technology for the manufacture of plastic automotive components with embedded electronics and power distribution. The said electronics sub-systems are simultaneously packaged within the automotive structural thermoplastic (TP) component during the injection moulding process. Such innovative process and product integration represents an opportunity to significantly reduce component counts and wiring loom overhead for the vehicle. The assembly, weight and cost advantages envisaged from the proposed technology will satisfy the ever-increasing demand for automotive suppliers to manufacture complete, ready-to-assemble, reconfigurable component modules with superior reliability and as such may contribute to the increased incorporation of vehicle telematics.The paper addresses the technological and economic implications of the proposed overmoulding technology, presenting particular aspects of technological hurdles such as thermal, electrical and process requirements in the production of highly integrated polymer encapsulated electronics products. This paper highlights the findings derived from experiments undertaken to explore critical factors in the manufacture of such encapsulated electronics sub-systems, including such variables as electronics interconnection, materials selection and interactions and moulding process parameters.
Gives a short history of “smart” in relation to the field of instrumentation. Defines the boundaries and suggests that a smart component should incorporate some combination of the elements of an application system which includes some element of control, computation or decision making. It should also enhance the functionality, performance or exit of the end system. Presents a number of examples of smart functionality and smart components and concludes that suppliers of sensors and actuators will take a leading role in the smart revolution.
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.
