Ryan,

I am not sure if this number was given to you. My
experience with v-groove is that the resulting web
thickness should be around .012". This will provide
for strength and allow for easy break apart once the
circuit has completed its smt/pth operations.

The .012" thick was what we use at Digital/Compaq when
I was there.
