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

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.

Reaching out to all conformal coating experts, please help! While setting up conformal coating using the automated atomized spray, we observing issues associated with conformal coating wetting on the following regions: 1) Component edges 2) Metalli

Hey Phil, i'm just curious what your rework processes are for your hardware after conformal coating is applied (if any). I'm interested in conformal coating as our hardware can be exposed to moisture rich environments at customer sites but to my kno

try Flux Atomization Flow - 15 CFH

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

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.

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.

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