Abstract Scope |
Aerosol JetŪ Printing (AJP) is a widely known printing method for Printed Electronics. The process can be divided into 4 fundamental sub-steps: atomization, transport of aerosol, collimation, and in-flight jet. Fundamental studies regarding these processes are rare to find. Hereby, in-flight jet visualization of silver and PEDOT:PSS inks after exiting the nozzle and before hitting the substrate, was performed by Phase Doppler Anemometry (PDA) to analyze the particle size and speed of an aerosol jet at different gas flows combinations (Focusing Ratio). Test structures of the same inks were also printed and their linewidth was measured by optical microscope. The results were analyzed and correlated each other when possible. Such fundamental study can help to predict printing output as width of the printed pattern, concentration, etc. Such parametric studies can also help to optimize process parameters and ink development.
