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.
