Tom,
How much of a cost adder was using 2 mills core as oppose to 4 mills? Did
you achieve significant reduction in high frequency decoupling caps due to
the increased plane capacitance

I have used 2-mil core with 2 oz copper on each side for a set of boards. I
had good results. In my application, the 2-mil cores were to separate power
and ground planes.

Subject: [SI-LIST] : 2 mil Core ?! Can I use it ?
Hi,
I designed a high density PCB with tight restrictions on its width.
my PCB manufacturer asks if I can use a 2 mil core with 0.5 oz copper on
each side and
by using it, I'll be able to expand prepreg layers in the board.
my question is, has anyone have experience with 2 mil core size ?
thanks,
