Sorry, the world of mils and microns is new to me. It is 0.2 inches! - Scott -----Original Message----- From: TechNet [mailto:[log in to unmask]]On Behalf Of Chuck Brummer Sent: Thursday, November 29, 2001 07:58 AM To: [log in to unmask] Subject: Re: [TN] Flexible PC Board 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.
