Hello All,

Can someone point me to the section (s) in either IPC-6012 or IPC-A-600 or
other standards that explains the acceptance criteria for Solder Mask
UNDER-CUTTING?  Please go to Steve's web-site following the links below to
see a few pictures of a Solder Mask defect that was discovered by our
customer (they only stated "reject due to severe undercutting").  With this
situation, we are trying to help our China source fix this issue, and we
need to help them understand what section (s) of the standard (s) they
should be looking at so they can establish a corrective action.
