Hi Technetters !
In the last P.C.Fab ( Dec.97 ) , p. 38 , Tim Apol of Continental Circuits
published paper with very promising title " Directional Plasma Etch " .
I reed this paper several very carefully , but finally I found only the
information , that Continental Circuits has this technology , but nothing
concerning HOW !
We made several trials in the past , but all we got - the same extend of
etched epoxy downward and latheral . We tried to etch the copper overhang ,
but the final result was non - satisfactory .
What is the trick ???
Who is ready to shear his experience ???.
Merry Christmass and Happy Hanuka to everyone !
