Eric Jassens For good technical infor from a manufacturer suggest you talk to Dennis Cantwell of Printed Circuits Inc. 612-888-7900 or Jeff Flammer of Dynaco 602-968-2000 or if you need good info from a supplieer try Bill Jacobi at Sheldahl 507-663-8000 or , course, Dupont at 800-243-2143, I can't remember a good contact but they can help you. Hitachi was the initial leader in this material and makes a good adhesivless flex.
