Try Dupont for the FEP material - not easy to get any more - I doubt they
have your construction. Tring to bond FEP over .020 copper - I hope you have
developed some very fancy press pad makeups otherwise you will never get it
to seal.

Subject: [TN] Need Flex Material Sources/Distributors


Hello Hello,

I need to find a some Flex Material sources.
I've made some inquiries but that I would include the list in my search.

IPC-FC-232A/3 -C1E2M13  (FEP cover layer)

IPC-CF-150, CF-W7-14N  (Copper Core)
Alternate material: 0.20 strip copper QQ-C-576, temper cold-rolled soft
annealed

And for fun, ask your plating engineer/chemist if they want to plate up to
14 ounces (~19 mils) of copper?  Mine freaked.

Off list, on list what ever works.

Hans
