You have a lot to think about! What does the flux manufacturer recommend as far as specifics like water temp or pressure? Do they recommend high temp di-water a detergent or saponifier? Do you currently have a cleaning machine, batch cleaner or inl

We use Kester 979 no clean flux in our Ersa.

If you are, in fact, running a No-Clean solder paste: Different no-clean solder pastes will leave different types of (benign) residues. If your paste has been qualified from a Bellcore/SIR/Electromigration standpoint, any residues remaining will NO

Change pastes, although insufficient heating may leave excessive residues. Is this on one board or all products? No Clean or water soluble? Do you profile accurately or "guesstimate" your settings?

Dear All, In order to understand the soldering technologies in SMT, I'd like to understand why some cards are soldered and then cleaned, or only soldered whitout water cleaning nor "ultra sound" wavelength. I mean that I wonder why we use toxic flu

I got an inquiry from one of our electronics labs with regards to their soldering processes. They use eutectic (63% Sn, 37% Pb) solder. For liquid flux they are currently using Kester 186, which is an old-school, full rosin (RMA and ROL1) flux that c

esoderberg: So, why do you want to clean your no-clean flux residues?

Just curious� Why only localized cleaning? Why not clean the entire board? Localized cleaning by nature is labor intensive. Mike Konrad Aqueous Technologies (909) 944-7771 ext 29 www.aqueoustech.com konrad@aqueoustech.com

Hi esoderberg - I was wondering if you had tried altering your soldering profile to try and fully solublize the no clean flux residues and elimate your cleaning dilemma? You can check out my company's website if you want some free reference material

A PCBA contains a couple of parts that are not sealed and can't be water washed. We hand solder these with no-clean after everything else is water washed. The designer says the no-clean residue must be completely removed so that it will not affect
