We have boards that inadvertently ended up with hard gold finish. As a
result we have 50 microinches of gold causing all kinds of headaches
at assembly.
We asked to have the extra gold stripped off but I was told it was not
possible.
Is there no way to dissolve the gold off? Otherwise we have to get
another batch made and they're expensive.
Mercury bath? Hot cyanide? Microtome? Have an immersion silver finish
over the gold!!! Argghgghgh anything!!
I'd try Brasso, don't know what the US equivalent is.
