I have a customer who is interested in making PWB's with polysulfone
(apparently one of their customers requested this). I have done some research
and found it is sold under the trade name of Udel and is made by Amoco
(actually BP). It is a thermoplastic material and is available with up to 30%
fiberglass. My questions are:

1. Does anyone know that the polysulfone is, in fact, used to make circuit
boards?

2. What are the properties that are desirable with this material in a circuit
board application?

3. If used for circuit boards, would you want to use material with the
fiberglass?

4. Can you get copper clad sheets of the polysulfone or do you have to press
the copper yourself?

5. If the answer to #4 is yes, where do you get it?

Any help out there would be appreciated.
