Chang,
Our results have been from electroplating after applying a silver spray for
conductivity. We have noticed an uneven buildup of metal on the sl part due
to the nature of the process. This build up caused undercuts close to the
face of the tool while not generating full coverage in the depth of the
tool.
Hope it helps. Good luck.
Carl Dekker
