Rick,

The IPC has begun such an effort.  The Plugged Via Performance Task Group (D-33d) is
scheduled to meet at the Expo in San Diego next Wednesday from 1:30-3:00 pm according
to my program schedule.  The program states "This task group will develop acceptance
criteria for protecting plated-through holes, blind and buried vias.  The work of this
task group will be submitted to the Rigid Board Performance task group for inclusion in
the IPC-6012 B Revision."  If you wish more information, contact me off-line and I'll
see if I can direct you to the proper IPC staff liaison and chairman of this task
group.
