I don't think there is a standard. There are several ways we do it for our customers. First,
use .100 spacing between parts. Tabs can be .150-.200 wide with small holes along the edge of
the board in the tab itself to facilitate breaking. Another way is to tab and score along the
edge of the boards at the tab. A third way is to make the tab .050-.060  wide with no holes
for breaking.
