610F is for assembly. What you are looking for should be in one of the PWB fabrication standards, such as 6012, 2222, or 2221.

Fellow TechNetters:
In the above stated standard DON"T see anything that refer to a defect from the desmear process which created a bow/flex, hour glass shape, on the copper hole wall from uncleansed debris. No lead will be inserted in this PTH. Is this type of anomaly acceptable. I don't suspect that the laminate is FR4 at this time. Perhaps later will identify.
Victor,
