Nagase ChemteX - Materials and Process Innovations in Fine Line Conductive Ink Printing

Fine line printing for advanced electronic applications requires careful coordination of ink chemistry, screen construction, and substrate properties. This presentation highlights recent developments in conductive ink formulations and processing that improve line definition and electrical performance. We also examine the critical role of screen parameters—such as mesh count and emulsion profile—in enabling ultra fine features. Finally, we discuss how substrate surface energy and topography influence ink wetting and resolution. Together, these factors provide a practical roadmap for achieving reliable fine line printing across a range of applications.
