Hi everyone,

     If anybody have the fax number or e-mail address of the following
     company please let me know. I am interested in getting more
     information about their sodium etching/activating processes.

     1. Gore & Associates - Tetra-Etch

     2. Acton Associates, Inc. - Fluoro-Etch

     3. Matheson Gas Products - Poly-Etch


     If anybody have experience with these processes please let me know the
     pros and cons. Thanks in advance.

     Regards
     T.G. Yee
     Hadco Corp.
