Yes. This is why I said that the board would need to be fabricated as a breakaway board. > It would be possible for a fabricator >to make the panel equal to the board, but then there are problems with how >to hold the board without shadowing a spot during plating, not to mention >that most shops use large panels, with several boards per panel. Yes. That is not a practical solution. To plate the edges at the same time as the holes, the board *must* be fabricated breakaway. That increases cost for routing, which should be the only increased cost except maybe a little touchup if required where the tabs broke away. If one really wanted *no* gaps in the edge, those gaps where the tabs were could be manually plated with a plating pen, practical with a relatively small run.
