The Smart Sonic 440-R SMT detergent is certified safe and effective by the EPA (I downloaded the documents from their web site). Is this true of the other chemistries that you referenced? If so, where can I find the documentation? If not, why not?

SmartSonic states that they will not sell their 440R chemistry unless it will be used with their machines. But to answer your question, the following manufacturers make ultrasonic stencil cleaners compatible with 440R and many other chemistries. Aq

Nothing against Smart Sonic I just want to see what others are using and why. I have heard their chemistry is great, but that the machine is not as robust as other companies. Peter

Rob, How does your chemistry stack up against the 440R? I see you mentioned ease of maintenance as one down fall in that chemistry's make-up. Could you elaborate for me. Thanks.

To all following this string, there is at least one other chemistry which has passed the South Coast Air Quality Management District testing and has Clean Air Solvent CERTIFICATION! Call Zestron for details 703-589-1198. Dave

Peter, I have completed trials on various machines for cleaning both SMT stencils and misprinted PCB�s for solder paste and adhesive. Why do you have a preference with the cleaning solution, is this flexible? I can recommend a machine which we purcha

I would recommend pH neutral chemistries, particularly if a semi-automatic machine is to be used. There are many chemistries available. A partial list of chemistries that I have tested, and that are compatible with a variety of cleaning equipment i

Hi Dave, I looked into the South Coast Air Quality Management District Clean Air Solvent Certification when I was having my problems with VOCs. The problem with the SCAQMD CAS Certification is that it only certifies chemicals as they are found in t

Mike, I don't feel that I am putting too much emphasis on the EPA certification. If it wasn't for the EPA, I would still be using freon in my old degreaser and would not have needed to change chemistries 3 times in 5 years. Why fight the EPA if th
