Untersuchungen zur Sinterung Aerosol Jet und Ink Jet gedruckter Ag- und CuNiMn-Mikrostrukturen

Printing of electronic components by printed metallic nanoparticulate microstructures represents a promising approach for cost-and resource-efficient production. Morphological properties and sintering behaviour of Aerosol Jet and Ink Jet printed copper-nickel-manganese resp. silver structures are investigated. Oven and short-term sintering techniques, like photonic and electrical DC sintering, are applied. It is shown that a highly porous morphology, achieved by Aerosol Jet printing, is beneficial for electrical DC sintering of silver. On the opposite, oven sintering requires densely packed microstructures achieved by Ink Jet printing. Photonic sintering is the only process able to render printed CuNiMn-microstructures conductive. Electrical DC sintering is suitable for highly conductive silver structures and an extended process also allows to obtain a defined track resistance.
