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

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

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

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.

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
