Teflon needs good support structure, not so stiff as FR4. May need good hangers in P-P and soldering so they dont warpage.

We have a customer using a Teflon laminate in one of their designs. Can anyone tell me if there are things we should be aware of when processing these boards through standard surface mount processes (print, place, reflow, clean, etc) that are different than say standard FR4 type materials?
