Treating metal surfaces with a modified oxide replacement composition

摘要

A method for treating a metal surface to microroughen the metal surface without forming a reddish brown to black oxide film on the metal surface. Modified oxide replacement compositions derived from oxide replacement compositions are prepared by altering the amount of at least one component in the oxide replacement composition to a level above or below an optimized amount of that component in the oxide replacement composition. The modified oxide replacement composition is then used to microroughen a metal surface without the oxide film forming on the metal. A temporary photoresist may be laminated on the treated metal surface and portions of the photoreist developed and stripped from the metal without concern for resist lock-in occurring.
