Metal rinsing process with controlled metal microcorrosion reduction

摘要

Process for rinsing a metallized substrate subject to metal microcorrosion using an acidic aqueous rinsing solution characterized in that the rinsing solution comprises at least one strong inorganic acid in an amount enough to reduce the alkalinity of the rinse solution to a level low enough to reduce microcorrosion of the said metal layer while rinsing.
