Not necessarily a problem, not pretty but not a problem if the hole walls are good. If you section is the copper plate height requirement met? If yes and they passed E test then they are good. Did you get a micro section report with your certs? Again, good micro section, good e test they are good, Hole walls have etch out, not so good. that's my 2 cents, Chuck Charles W.

I definitely would be kicking these back to the vendor!
