As much as I like your understanding I would like to add the following as my input.
I do not see that the 6.3.1 is in conflict with Table 6-2
But may have been better understood if added as item F. With the understanding that it only applies to thermal planes or conductor planes that act as heat sinks.
Please remember 6.3.1 is an exception to table 6-2 not in a conflict with .

Good Morning Carl,
For starters I would like to say, "Good question, this is going to spread
hysteria throughout Technet land!" This reminds me of the good 'ol days
providing clarifications and interpretations of mil specs/std that was
somewhat entertaining.
IMHO -- you are correct in your interpretation that the noted exception on
page 6-7 applices to class 2 & 3 (also note that this page conflicts with
table 6-2 Class 2 that states that 75% hole fill is required while 6-7
states 50% is acceptable). BUT, the user must ensure that this is
acceptable for the intended use environment and all the 'ilities are
unaffected. I would much rather accept 50% hole fill any day than to
perform touch-up -- oh the joint looks better now, but seriously let's look
at what damage has been done to innerlayer interconnections (oh, we can't
see that so it must be okay).
Have a nice day!

Hello,
Looking for the groups opinion(s) on the vertical fill requirement stated on
page 6-7 of IPC-A-610C.
Is the exception pertaining to the Defect Class 3?
