Hi All,

        Some time back there were some alternative processes for etching teflon
boards mentioned on Technet. The ones I am seeking to find were those of a
Sodium etch I think. What sodium compound it was, I don't remember but it was
not the Napthelene. I am familar with the Plasma alternatives but would like to
know more about the chemical alternatives and/or the suppliers of the
chemistry.

Responses would be greatly appreciated.
Regards,
Les Connally
