99353 - Effect of Temperature Exposure on Performance of Inkjet Printed Circuits With Surface Mount Components 

In this paper, Inkjet printing as an additive technique is utilized to characterize the performance of circuits with surface mount components. In addition, performance is characterized when the circuits are exposed to 50°C temperature aging. Circuits such as signal filters are more often than not used in electronic systems and very common for them to experience moderate temperature aging. Additive manufacturing of electronics is rapidly evolving with novel end applications due to the research efforts currently being put in. Due to the constant pressure of innovation and expanding the implementation of printed electronics in current manufacturing lines, research efforts are continually being put in to understand its capabilities. Among the many techniques, Inkjet offers many benefits as compared with other techniques such as non-contact, lower capital expenditure, lower material usage, and mass manufacturing due to hundreds of nozzles. The technique has tremendous potential in processes with rapid prototyping, whilst reducing waste. Inkjet printing utilizes materials that are in liquid form that can be generated into droplets that are deposited as per the required design. Furthermore, the technique can utilize both substrates, rigid and flexible. With all the process development, of interest is the development of functional electronic circuits to demonstrate the capability of Inkjet printing. In addition, attachment of surface mount components on additively printed features is not completely matured yet. To that end, some of the commonly used applications such as low pass and high pass filters are demonstrated with surface mount components attached using additive printed interconnection material. Due to the nature of printing electronics, many applications are found in wearable market as well, which frequently experience temperature aging without getting the performance affected. Thus, to further extend the study, the functional circuits are subjected to 50°C exposure and change in the circuit response is presented. The aim of this study is to demonstrate the viability of Inkjet printed functional circuits with surface mount components and their response when exposed to temperature.
