======== Original Message ========
     Does anyone know of any preferred method of removing photoresist
from tooling holes in primary imaging before exposure.  The standard for
everyone
that I have seen is 1 of 3 methods.  1.  Hole punch removal  2.
Razor or reamer type tool  3.  Soldering iron.  All of these methods
work, although they are very labor intensive and time consuming.  It
would be great to somehow automate this process.  Any suggestions
would be greatly appreciated.  Thank you

How about punching/drilling the tooling holes after the panels are
laminated?  This tends to be cleaner than cutting or burning the resist.
