摘要
Disclosed are a method of preparing a conductive ink composition for a flexible printed circuit (FPC) and a method of producing a printed circuit board using the conductive ink composition. This method includes preparing a first solution by mixing a Ag-containing compound and a fatty acid dispersion stabilizer in a polar solvent; preparing a second solution including Ag nanoparticles reduced from the Ag-containing compound by adding a reducing agent to the first solution; phase-transitioning the Ag nanoparticles into a nonpolar solvent by adding a phase-transition agent and a nonpolar solvent to the second solution including the Ag nanoparticles; and separating the nonpolar solvent including the Ag nanoparticles therefrom.
