Abstract
A solution comprising a palladium compound and a polyaminocarboxylic compound has been found to be suitable as a bath for electroless plating of palladium onto copper. Use of such a solution produces a plated component comprising a copper surface and a palladium plated coating having a thickness of between 0.01 micrometers (μm) and 5 μm. A method for electroless plating of palladium onto a copper surface of a component includes preparing a bath having a palladium compound and a polyaminocarboxylic compound. The copper component is submerged in the bath to plate a palladium layer on the copper surface of the component. The component resulting from the plating method has a palladium layer plated on the copper surface.
