| Abstract Scope |
Printed electronics is a fast-growing field due to its application in wearable and internet of things. While many have demonstrated examples of printed circuits on various substrates, such as glass and polyamide, few investigate the thermal impacts of printing, which like in the semiconductor industry, play a crucial role in its performance and reliability. A reliable and simple tool for measuring the thermal properties of these prints is critically needed. A promising technique for in-situ characterization is known as modulated photothermal radiometry (MPTR), whose measurement is based on the sample thermal frequency response. In this work, we present modeling results of printed silver on various substrates. We showcase how the printed film parameters such as substrate thermal conductivity and paste thickness impact the thermal frequency response and the sensitivity of MPTR to the film. |
