We have a customer enquiry that requires PCB assemblies to be cleaned to J-STD-001 / -004 class 3. We use both water based and no clean process chemistries. No clean flux residues are not permitted and would therefore have to be cleaned. My question

Hi Russ, Can you please clarify on what you mean by "after wash they should be gone since it is water soluble,".....the flux would be water soluble or otherwise, how does that relate to solder balls being removed by cleaning?...i can see them being r

I am currently using a water wash batch cleaning system, closed loop. I am looking for a better result when cleaning and thinking of introducing a chemistry. What is the best chemistry to use? Will using a chemistry to clean actually provide a bett

Hi matt- You describe the board but did not indicate the components being inserted (even there is a part being inserted). Assuming your hole dimensions are ok... Are you cutting and clinching the parts? If so what is you clinch angle? We to have mu

Its kind of nice to be able to put a dirty stencil in the cleaner and get a dry clean one out. That pretty much points to the spray units with a dry cycle. Things to consider, chemistry consumption, how your stencils are bound, maintenance,and of c

Here are three VOC free chemistry suppliers. Their chemistries will clean no-clean and RMA flux residues: www.zestron.com www.kyzen.com www.envirosense-inc.com

Hi, my supplier is using the same Aqueous machine to clean the boards for 2 different customers. My product uses the chemistry of leaded clean flux meanwhile the other product uses the chemistry of lead free with no clean flux, however that product r

Flux is used with both lead and lead free. Lead free usually or always uses a no-clean chemistry while lead uses both no-clean and water soluble dependent upon the application. As far as temp profiling a standard way to go is melting point + 30 C. f

Ok, maybe I'm missing something here: It's a no clean flux type AND your going to wash it? Why not migrate to OA Flux and just run DI water with Ion-Exchange beds? Benefits: No need for ultrasonics No need for chemical isolation No need for cleani
