Does anyone out there use anything besides alcohol in their automatic claw/finger cleaners in their wave solder machines? We are nearing our VOC limit and are looking into other chemicals (VOC-free) for cleaning. Thanks David

You might want to try Zestron. They make a lot of different cleaners. We use Zestron SD 300 if we clean a stencil by hand. It works great, a lot better than alcohol. Go to http://www.zestron.com. Hope this helps.

We are using so called no-clean fluxws for our small batch production, however the results are not always very visualy pleasing with white powdery deposits being the norm. I would like advise on the best avenue to explore for a small batch cleaning s

I think most have summed up the first pictures also is the drillng looking like it is misregistered as well. Better to do a solvent test to determine resist cure not the old stuff the newer chemicals show under cure problem much better. Try your st

the board in question is from Foba Laser Engraver, it's a surface contamination coming from.. everywhere, a lot of moving parts that are lubricated. I'm now studding chemicals that we may use for our kind of rework & cleaning. We may think of modifyi

I would recommend the following paper entitled "Cleaning for Reliability Post QFN Rework" by Mike Bixenman (Kyzen) and myself (Aqueous Technologies). While it discussed cleaning under QFN's in a batch environment, it is also applicable to cleaning u

There are chemistries out there that will solublize some post-solder NC flux residues. I have had success with Zestron material Vigon A200 and Petroferm material Hydrex DX. Go to http://www.zestron.com and http://www.petroferm.com These are chemical

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

Murray "No-clean" fluxes/pastes should not normally give "white residues". Before exploring cleaning, which is costly for small production levels, I suggest you may care to find out why you have these residues. To help you, can you please answer th

Ok lets put it this way. If the PCB house used a high quality mask and properly applied it to a properly cleaned surface and properly cured it, then as Dave stated above there are only two things that can destroy it. Excessive heat and overly aggress
