I have a product that requires a .006 dia. laser ablated via from lyr 1 to
2.  I'm required to use glass re-inforced FR-4 as a dielectric.  The
dielectric is approx .0035. I can either use a single ply of 2313 or 2 plies
of 106 prepreg.  Which would be the most favorable construction in terms of
laser hole quality and subsequent processing?
