And while discussing methods of putting holes in boards, don't forget
that you can laser thru the top copper, all the fiberglass and down
TO, but NOT THRU the bottom copper. Makes cool blind thru holes.
Also, one can punch holes in a board. VERY fast as you can do
bunches at a single pass.
only way ? no, but carbide is a smart way !
