In regards to cleaning RMA solder paste from stencils; Right now we are cleaning the stencils by hand. I want to get away from this by going to an automatic cleaner. Any recommendations for ultrasonic stencil cleaning systems using 440-R SMT deterg

We don't own one, I'm a bit interested to see what you end up with. We do have a triden pcb wash, and I know Aqueous Technologes makes a lineup of misprint and stencil cleaners. We had an engineer in from Zestron chemical company, and while they don

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

Our company and most others do no specify any specific chemistry but offer equipment with configurations for running the best chemistry based on your application. Listed in one of Mike Konrad's postings are the contacts for chemistry. Ease of maint

This is brutal. I think we should call a truce. Mike has very good points and his quotations from the EPA letter are fact. If there isn't a competitor of Bill's who hasn't seen this letter I'd be surprised. We could go on and on about this and th

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

Hi Dale, I have copies of the articles of which Mike references. If you need copies for support, contact me at: bill@smartsonic.com. Rinsing should be done by ultrasonics also. Spray in atmosphere systems will not penetrate into the same tight ar
