<p>A method of providing a direct electroless palladium deposit on a copper surface is described. The method comprises the steps of (a) catalyzing the copper surface by applying a pre-dip composition to the copper surface, the pre-dip composition comprising a reducing agent; and thereafter (b) contacting the catalyzed copper surface with an electroless palladium composition to deposit a layer of palladium on the copper surface.</p> |
