ALLOY NANO PARTICLE OF SN-CU-AG, PREPARATION METHOD THEREOF AND INK OR PASTE USING THE ALLOY NANO PARTICLE

摘要

PURPOSE: An alloy nano particle of Sn-Cu-Ag, preparation method thereof, and ink or paste using the alloy nano particle are provided to improve electric conductance and have low firing temperature. CONSTITUTION: A manufacturing method of an alloy nano particle comprises the following steps of: dissolving solvent tartrate and surfactant with solvent(S101); forming tin nano particle by adding reducing agent into the solution at 100~260°C(S102); and forming tin-copper alloy nano particle by adding copper compound into the solution with reducing agent(S103).
