METHOD OF PREPARING CONDUCTIVE POWDER

摘要

PURPOSE: A manufacturing method of conductive powder is provided to prevent a nickel plating layer from being separated from a core material during a gold-plating process by forming the nickel plating layer with multiple layers on the surface of the core material. CONSTITUTION: A manufacturing method of conductive powder forming a metal electroplating layer on a core material formed with synthetic resin material powder, comprises the following steps: collecting the core material from a tin chloride and palladium chloride solution, and washing the outcome for forming core material slurry; dispersing the core material slurry in a nickel plating solution to form nickel-electroplated powder; dispersing the monolayer nickel-electroplated powder to the nickel plating solution to form a multilayered nickel-electroplated powder; and dispersing the multilayered nickel-electroplated powder to a substituted gold electroplating solution to form the conductive powder.
