| Abstract Scope |
Pad printing shows promise for fabricating conductive traces in electronic devices, offering advantages like 3D surface printing and narrow line widths. This study explores near infrared sintering parameters for optimizing the resistivity of pad-printed silver microparticle-based features. This sintering starts 3 seconds after the completion of the printing process. Using a custom pad printing machine, 17.5%v/v silver ink was printed into 10 mm long, 150 μm wide traces. Results indicate that sintering time significantly impacts resistance, with improved electrical conductivity achieved within the first 2 seconds of sintering. Sintering power also plays a crucial role in optimizing the process. These findings provide valuable insights for developing reliable, rapid, and high-performance pad printing techniques for electronic applications. With these results a model for sintering behavior can be developed. |
