So if it's unplated, why does an unsupported hole have a breakout (or more appropriately a "no breakout") requirement (IPC-6012 Table 3-5)?

Peter, a supported hole in a PWB is plated through the board according to IPC-T-50 (Terms and Definitions for Interconnecting and Packaging Electronic Circuits) " or otherwise reinforced". The unsupported holes do not contain plating.

Technet,
Can anyone explain the difference between a supported
and unsupported hole on PCB?
I am reading a section on IPC-A-600 RevF and section
2.10.3/4 specify difference acceptance criteria
according to the hole type.
Rgds,
Peter
