Hi Gary,
As far as the Micro Electronics Group of AT&T Reading and Allentown PA.
now (Lucent Technologies); minimum via land 25mil / hole size 14mil.
This must be shown with the "hole" toleranced on the Fab drawing with
upper and lower limits ie.: 25-14 +3/-0 .
Check with your friendly fab vendor to comply with the spec.

Best Wishes,
Chris
