Dewey -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Paul Reid Sent: Friday, April 18, 2008 5:46 AM To: [log in to unmask] Subject: Re: [TN] Out Gassing A PWB fabrication company I worked for years ago left a rack of boards in a sulfuric acid bath over lunch. The operators figured sulfuric acid removes copper oxides so it would be a good holding bath. The resin was softened and swelled. In assembly, or heating with a soldering iron, the resulting out gassing produced what looked like mini volcanic eruptions from which copious amounts of white smoke issued. No degree of baking could prevent the out gassing.
