Abstract

Digital printing of electronic circuits includes the deposition of a variety of particles, which determine the electronic properties after sintering. In general, the particles are non-colloidal which means that sedimentation occurs. In getting sedimentation under control, a wide range of particles can be printed.In a first step, the sedimentation behavior of silver and glass particles is characterised in different organic solvents taking into account different sizes, shapes, densities and concentrations. The analysis of the sedimentation behavior is based on an optical method which allows for the detection of small concentration changes. In a second step, the particles are stabilised using commercial dispersants and the stability of the inks is evaluated. The influence of the particles on the viscosity is studied as well as the influence of the particles on the surface tension and wetting. Finally, chosen inks are printed on ceramic substrates by inkjet printing. After drying by evaporation and sintering, the shape and electrical properties of the electrical structures are analysed. The article discusses the design of functional particle inks, highlights properties and interactions and demonstrates the functionality of the designed inks by printing a capacitor.
