Hi guys. I am trying to copper plate some gold features that are surrounded by
SU-8. The problem I get is that the plating takes place only in a few of those
features. I want to believe that there is some residue left on top of the gold.
I ve also tried longer development of the SU-8 to make sure that there is none
left on the gold traces but still I get the same problem when I copper plate.
Any ideas??

Thanks
