I have found that anything over .062 should be on
high Tg material.  Found that the holes do not stand
up well and with a high aspect ratio there may be
thin wall holes in some areas.  It should not cost
more than 5% for material ONLY for this material.
(I quote boards and this is a fact with my company)
However 170 degree is plenty.......
