Maybe Michael got the answer he was looking for in response to his question
'why does it need a breakout spec' but I am confused.  I thought that what
was really being asked might have been what is the definition of 'breakout'
for an unsupported hole?  I would like to know that answer.  Is breakout the
condition where the hole may not be centred in the pad and the ring around
the hole is broken?  Is the definition any different for a plated thru hole
- possibly a break in the plating inside the hole?

Thanks,
Genny.

In my experience a break out condition on an unsupported hole is a night
mare when you go to solder especially by hand.  The breakout causes the rest
of the pad to lift and then good luck trying to get any type of solder
joint.
