PRINTING INK FOR SILVER CONDUCTOR CIRCUIT AND METHOD FOR FORMING SILVER CONDUCTOR CIRCUIT

摘要

PURPOSE: To obtain the product containing a specific resin component, a silver component and a flux component, high in accuracy of position after backing high in resolving power of line/space and capable of forming a fine pattern having good leveling property on a substrate. ;CONSTITUTION: The product contains (A) a resin component selected from a (modified) alkyd resin, a fatty acid epoxy resin, an urethanated oil, rosin and maleated oil, (B) a silver component (preferably metallic silver powder singly dispersed and having 0.1-0.5μm particle diameter) and (C) a flux component. As the component C, e.g. a PbO-B₂O₃-SiO₂ based glass frit having 350-600°C softening point is used when a glass substrate is used as a substrate for printing a pattern or SiO₂-Al₂O₃-CaO based glass frit having high softening point is used when an alumina substrate is used as the substrate.;COPYRIGHT: (C)1993,JPO&Japio
