A method of producing a flexible nickel phosphorus coating on a substrate. The substrate includes a dielectric material having a copper layer thereon. The method comprises the steps of: (1) activating the substrate with a palladium activation solution to catalyze the substrate, and 2) contacting the activated substrate with an electroless nickel phosphorus plating bath comprising: (i) a source of nickel ions; (ii) a hypophosphite ion source; (iii) at least one metal complexing agent; and (iv) an organic flexible additive. The nickel-phosphorus plating layer deposited on the substrate shows a columnar grain structure.
