Dear Susan,
Thanks a lot for your feed back.
But if IPC does not specify anything, on what basis is the hole quality
assessed ?
Regards,
Swati...

There is no requirement for hole roughness in any of the IPC board
specifications. The
nailheading requirement was removed several years ago since it was not a
"defect", but
an indication of less than optimal drilling.
