Abstract

Se describe una composicion de materia de inmersion de estaño que comprende un compuesto que tiene un ion de estaño divalente, un compuesto que tiene un ion de fluoruro, y un compuesto que tiene un ion de hidrogeno ácido. También se describe un procedimiento para tratar una aleacion de aluminio-cobre o de aluminio-silicio para mejorar la adhesion de capas metálicas a la aleacion, que comprende poner en contacto la aleacion con una composicion de inmersion de estaño ácido para producir un revestimiento de inmersion de estaño sobre la aleacion, y poner en contacto el revestimiento de inmersion de estaño con una solucion de ataque para remover substancialmente el revestimiento de inmersion de estaño y producir una superficie de aleacion, grabada por ataque químico.
