I am interested in the Plasma desmear process. I have been reading alot about this type of desmear technique and dont quite understand the variables involved. >From what I understand there is a combination of three gasses that combine to create the "plasma" state ( the most common oxygen, nitrogen and tetraflouromethane). How are these gasses controlled and what effects do the ratio of the gasses effect the etchrate? T.A.
