given that it is manually routed then there are no big issues
we have done them without problems
(as you may know if you were to use the autorouter it won't see the arc
formed boundary)
draw 2 concentric circles 125 or 093 (router bit size) different in size
and hold the bd to a rectangular shape with 2 or more tabs for wave
surfing
put a few little holes in the tabs to singulate the board from it's
carrier
depending on what you are doing with it you may need to clean up the
break away areas
