Fellow TechNetters:
I did not receive a reply so I posted my inquiry again. It's Monday so things might be slow! I did review IPC-2221B Table 6-1 Electrical; Conductor Spacing. I guess if I have drill misregistration, as long as it doesn't come closer than 2 mils, it's OK! I needs comments and/or suggestions. This inquiry is on a cross section method. I will plan to do a flat section later.
Victor,

Subject: Electrical Spacing, Clearance to PTH copper barrel, IPC-6012C
Fellow TechNetters;
I am searching for info on electrical spacing requirements between an internal conductor/Land to PTH copper barrel distance. In my case it can be either drill process misregistration and/or internal core misregistration. In either case what is the closest distance that a conductor/land can be to the PTH copper barrel.
Victor,
