cem1 is cool, but i don't recomend milling.
Look in the group links -> design rules -> laminate FAQ.
the milling might destroy the glass layer.. (no idea how deep that goes).
But it is VERY smooth to work with, cutting "like paper" and drill ing
"like butter".
I only use it for prototypes that will not be used long-term because i
only have a very
small amount and loads of FR4 for permanent boards.
