摘要
A palladium-tin alloy plating composition of a copper alloy and an iron-nickel alloy, a plating method thereof, and a plating body thereof. The palladium-tin alloy plating composition comprises an aqueous solution containing 5-20 g / l of palladium, 2-8 g / l of tin, 20-100 g / l of at least one conductive salt and 2-10 g / l of complexing agent, 0.1-0.5 g / l and a stress reducing agent 0.05-0.2 g / l. The palladium-tin alloy plating method is carried out by immersing the copper alloy and iron-nickel alloy material into the plating composition and then flowing the current to the plated body at 0.7-5 ASD. According to the present invention, a palladium-tin alloy plating layer having excellent solderability and flexibility is formed on a plated body made of a copper alloy and an iron-nickel alloy material, and a two-step process of plating a tin-lead alloy after silver plating, But also eliminates the emission of harmful substances such as lead, thus greatly contributing to environmental problems.
