I don't have one here at GD. I just had a client purchase an F200 solvent cleaning system (unheated) and they just love it. They had RMA flux requirements and were having issues with entrapped (encrusted) flux. They tried many different processes, including alcohol in a batch cleaner, none of which worked very well. They went to the F200 and have had zero issues since, and this was for military electronics. You need to make sure to use the correct frequency, etc. Dr. Sami Awad can help you with particular applications. Crest personnel know more than anyone else in the world about ultrasonic cleaning. I also am currently using one at another client facility which is the TruSweep 1875, and I am using a hot DI water and 5% saponifier mix to clean small BGAs with wirebonded die that we develop there. (I also work for other companies in Minnesota as a consulting engineer). I have not used the condensation units, so I cannot tell you anything about them. But I can only encourage you to talk to the tech people at Crest, they can help. ________________________________ From: Ray Kong [mailto:[log in to unmask]] Sent: Friday, February 20, 2009 11:50 AM To: Stadem, Richard D.

Crest cleaners are designed with the specific frequencies that are safe for cleaning electronics, and work beautifully for stencils and PWBs as well. My experience with Crest cleaners is that they work forever, with no diminishing over time. I certainly cannot say that for Branson. No, I don't work for Crest, nor do I have any interest in the company. I just have used Crest many times at different companies for the past 30 years, and all of the ones I have ever purchased are still working. They make a really good product, and they are very knowledgeable people. -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Ray Kong Sent: Wednesday, February 18, 2009 5:19 PM To: [log in to unmask] Subject: [TN] Ultrasonic cleaner for PCB Hi all, Can someone recommend a ultrasonic cleaner for mis-print PCBs?
