Dear Sir!

Landmark is a member of IPC Associate.
We have one technical question. So we expect your best idea.
We are reviewing 'Plasma Etching Machine' for smeare treatment on
Drilled Teflon Laminate and found out there are two (High and Low)
RF Generator frequency. say High means 13.86MHZ, meantime Low is
40KHZ.  Could you send your best advice which is better for
'Desmear and Etch Back' on Teflon board?

Our contact points are as follows.
