Angelo,
A wet etching technique for kapton was developed at CERN by Fabio
Sauli's group for making "GEM" radiation detectors. As far as I know
they have kept the tricks to doing it close to the vest but I think it
involves the use of EDP (ethylene diamine pyrochatachol). You might be
able to find some vague information in the iterature. See

Good luck,
Mike

Hi,
Does anybody know how to wet etching Kapton?
I want to make 60um diameter hole in a 50um thick kapton foil.
Can any one suggest some etchant/methods?
Many thanks!
