The attached images appear to be a result of a touchup process. We believe that this is not a fracture, but more of a condition where the solder touchup process did not completely flow the solder. Is this acceptable per J-STD-001 and IPC-A-610 Class

The only instant disqualification I know of is when you are caught wearing a Sears Poncho instead of the genuine article. If not sure of the difference, get Camarillo Brillo to through a Tarot to find out.
