Lead-free and cadmium-free electroless plating solution, method of electroless plating using the same, and nickel plating layer using the same

摘要

The present invention provides a lead-free and cadmium-free electroless nickel plating solution that has eco-friendly and improved stability of a nickel plating solution and has excellent plating characteristics. The lead-free and cadmium-free electroless nickel plating solution according to an embodiment of the present invention comprises a nickel metal salt for providing nickel ions for plating; a reducing agent for reducing the nickel ions for plating; a complex forming agent for forming a complex with nickel ions for plating and including carboxylic acid and alpha hydroxyl acid; and a lead-free and cadmium-free metal stabilizer for inhibiting the reduction of the nickel ions for plating and including an metal element.
