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.

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.
