jdomont, No-cleans are more difficult to clean than RMA�s. Even though no-cleans have a lower solids content than RMA�s, reflow and soldering profiles are normally more severe than those used for RMA. It is interesting to note that our most of our

Dear Sir, If you are looking for the best bang for the buck you will have to stop cleaning and use a no-residue paste instead of a no-clean. No-residue chemistry becomes totaly volatile in dwell time above reflow resulting in residue free boards. I

Patrick, When you say "no-residue" what exactly do you mean? Is there truely "no-residue" or is it "no visible residue"? What type of ionic contamination results have you experienced? If you take a bare board that measures 0.0 NaCl and reflow it

Mr. Dumont I want to be very clear on a couple of points. The intention of my response to your thread was to bring you a solution for your problem "free of charge" The no-residue is not developed yesterday. The no-residue is developed in 1988. Becau

Josh: Final cure of the LPI solder mask: 310*F for 45 minutes. Your board fabricator needs to do a better job. Most fabs do not check cure, because the processes subsequent to cure are so brutal that the fab expects the following process to highlig

Hi, We tried that, as the Soltec has a spray fluxer that can flux just the connector part of the board, however we get really heavy solder deposits on the rest of the board that has no flux sprayed on it, so we seem to need to coat the entire board.

Hi all, (I posted on eevblog also, figured I'd try hear as well since this seems like a semi "niche" question) I need some advice on PCB cleaning. Up to this point, our assembly line has strictly run NC paste, with all SMT parts. We never washed an

The very best batch cleaner I have ever used, and I don’t mean by a small margin, was an Electrovet MCS1000. I kept that machine running a very long time, but a software problem ended up being more than the company I worked for was willing to underta

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
