Hi all,

I've been reading the messages and looking at some of the links on
thru hole plating. I've also been to thinktink to read over their
stuff.

As thru hole plating appears to just be electroplating - I was
curious about how to properly connect a board...

ie: Most electroplating is (or at least appears to be from the way
I understand it) utilizing opposite charges, where one charge is on
the supply material (like a copper anode) and another charge on the
receiving material (cathode tied to the circuit board). As I
understand it all materials to receive the plating needs to be
connected in the circuit - so how does one plate a circuit board
where traces are not all connected to each other? By using a sheet
of metal pinned to the circuit board to make sure all traces are
tied to the cathode?

I realize what I have written probably at the very least appears
confusing, but unfortunately, I am confused at this point. Any help
would be most appreciated.
