Is the oven air or nitrogen? If it is air I would suggest more exhuast to pull the flux vapors out if the oven before they can condense in the cooling. If it is a nitrogn machine that makes it a little more complicated. If the filter system is clogge

If you have flux deposits on the cooling plates, try out Zestron's VIGON RC101...It is an extremely good product especially for reflow ovens and wave solder systems. Check it out...Minimal maintenance water based chemistry with no flash point...Much

We see spattered(spitting of flux or solder to nearby area) solder/flux on gold fingers.We view the gold fingers area under 30x before reflow and it is cleaned but after reflow we see flux droplets or solder on gold fingers. We tried to changed a new

We are currently using non clean paste and non clean flux in our manufacturing process. But recently our customer feedback that using a non clean process might cause flux blockage in via hole area and potentially might burn or explode the boards over

There is no shortage of reasons to clean your boards. Soldering or reflowing your boards leaves �stuff� on them. This �stuff� is normally corrosive and conductive (some fluxes / pastes are more corrosive / conductive than others). In either case,

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?

Bruno The real question about your troop using Kester 951 wave solder flux on boards is: how is the flux applied and controlled. See, when you apply this flux with your wave solder fluxer, it is ideally applied in a metered fashion with your fluxer

Hello, Could be that touchup operators are using too much flux. What are you dispensing flux with. Disposable or refillable flux pens are good to have around. | | | | hello to everybody, | | | | we have a really satisfactory no clean proc
