A couple of things to try as I just went through this myself. Checkout this link for pointers on plasma cleaning... http://www.nordson.com/~/media/Files/Nordson/march/Papers/The-Effects-of-Plasma-Treatment-Prior-to-Conformal-Coating-NordsonMARCH.p

Flux Residues In Lead Free Wave Soldeing Process

Does your fluxer provide for very fine atomization of the flux or is it more "droplet like" Great term huh?

Solder Joint

Chunks! Good to see you here. From what I've been taught, and from what I've read, the strength of the solder joint is in the intermetallic bond which occurs at the atomic level. A solder FILLET is an indicator that wetting took place.

Conformal coat material dispensed through epoxy needle?

Dow Corning 3-1953 is widely used when it comes to silicone based conformal coatings. Low odor, medium viscosity, can be atomized or needle dispensed. We have our operators fill syringe cartridges for any minor touch up.

Humiseal 1A33 conformal coating using automated atomized spray

Electronics Forum | Mon Aug 20 09:49:57 EDT 2018 | dontfeedphils

Not entirely clear on your question. We don't coat any of our hardware (assemblies are coated prior to hardware installation), so if coating needs to be reworked after this, then hardware removal is needed.

Nitrogen supply for new solder wave spray fluxer.

Agreed. If it's just a means of propulsion/ atomization the purity probably isn't too critical.

Wave Solder Fluxing

Electronics Forum | Mon Oct 26 11:11:48 EST 1998 | John Hardy

We have installed a Sonoflux atomized mist fluxing unit (Model 9500)on our Future 1 wave solder machine. We are concerned that the retrofitting of this unit may not have been appropriate for our equipment, as we are now experiencing many problems wi

Optiflux 500 Ultrasonic Fluxer Issue

Electronics Forum | Wed Nov 27 09:43:17 EST 2013 | mchawg

We recently rebuilt the generator and power supply on our '97 vintage Optiflux Ultrasonic fluxer. That cleared up all its issues except. Ultrasonics are reported by all indicators to be running in both Setup and Run mode, however, the nice rooster-t
