Jim,
Wow, takes a lot of adhesive to fill 3 oz.
I have been using Photo Imageable Coverlay, a free film. Usually I use the
1, 1.5 and 2 mil thickness. I know DuPont has at least 2.5 mil. Rogers has
a pretty good liquid but I don't think the coverage over corners will work
for you.

Subject: [TN] flex coversheet alternatives
Has anyone heard of an industry accepted LPI flex mask or photoimageable
coversheet. Squeeze out is becoming a huge problem on 3 oz. cu @ 8 mil
spacing.
Thanks
Jim H.
