Sorry, the world of mils and microns is new to me. It is

Scott,
2/10s of a mil? Like .0002"? You need a dielectric to hold
the conductor and I don't think
you will find anything that thin. We work with thinner
materials than most and we make a
number or parts on .0005" polyimide with 3 microns of
copper. If anyone has anything less
than that I would like to talk to them.
