The integration of electronic circuits in plastics using injection technologies: a literature review

Abstract

Abstract A great deal of attention has been paid in recent years to the integration of two and three-dimensional integrated electronic parts into plastics, both for their potential applications in modern human lives and for their outstanding properties, which include the ability to reduce product weight and space while increasing product reliability. The development of integrated electronic devices into plastics is advancing rapidly, owing to advancements in methodology and manufacturing techniques, which have significantly raised researcher interest in this topic. In-mold electronics (IME) is a term that describes an injection molding technology that integrates a printed foil with electrical components into a plastic part during the molding process. It is a revolutionary way to form two and three-dimensional products using electronic printed circuits. IME technology is comprised of three fundamental disciplines of study: electronics, materials science, and plastic manufacturing processes. Therefore, this review article aims to summarize the knowledge of these three primary fields to present an overview of in-mold technology. This article covers background history, a description of the In-mold process flow, and summarizes the recent real-life applications. Additionally, this article discusses some of the present technology challenges that must be overcome.
