Additively Printed Circuit Performance of Thermoformed In-Mold Electronics for Automotive Applications

The design and production of electronic components, especially in the automobile sector, could be completely transformed by In-Mold Electronics (IME), a revolutionary technology. IME provides benefits including better weight reduction, improved aesthetics, and increased space efficiency by facilitating the smooth integration of electronic circuits into intricate three-dimensional surfaces. Nevertheless, despite their increasing use, thorough research on the electrical properties of IME circuits is still lacking, especially for those made with screen-printing methods on polycarbonate (PC) substrates that are then thermoformed. It is still unclear how important manufacturing factors, such as substrate deformation, ink conductivity, and mechanical stress, affect circuit performance. The purpose of this study is to look into how the electrical performance of IME circuits made for automotive applications is affected by screen-printing and thermoforming settings. This study offers important insights into the viability and dependability of IME technology in actual automotive settings by examining resistance fluctuations, capacitance stability, and overall circuit performance both before and after thermoforming. The results facilitate IME's wider implementation in next-generation vehicle electronics by advancing our understanding of its design and optimization.
