Larry, this is a very complex issue, and probably does not relate to the
Baume of the Ferric Chloride your customer is using, but MAY have something
to do with the acidity, or more likely to adhesion of the photoresist.  SS is
perhaps the toughest surface to prepare for photoresist.

Why not give me a phone call to discuss this.  This is a matter way off the
Technet charter, and besides I am a very slow typist.
