Where on the assembly is the dewetting occurring? Factors that influence dewetting usually involve non-ionic contamination such as: * Residues from board manufacture including silicone surfactants from solder resist & HASL rinse contamination * Comp

As am doing screening right now, am not measuring the total cleanliness yet, i just observe by taking photos (FYI, am varying speed for conveyor belt for cleaning) and see whether the flux is able to be removed by certain parameters. the speed am usi

Hello. I would like to know the difference (if any) between water soluble flux and test socket cleaners (e.g. for Burn-In Board test sockets). As far as I know, they both remove oxides (tin & copper) with an activator, solvent and surfactants. Tha

Hello Dave, Water Washable (Organic Acid, OA) post solder flux residue is designed for cleaning in plain water without cleaning chemical additives. The real advantage of water washable flux was that it cleaned in plain water without additives � no

Let me expand on Cal's comments. Recommended??? What people recommend depends on whom you ask and what is their motivation. Me??? There is no hand lotion recommended for use in electronics manufacture. Brian Ellis [a respected author on cleaning

I think you can effectively clean under any other low standoff device. It's an issue of surface tension, pressure, and flow rate. DI water is the starting point, but the surface tension of straight DI water makes it difficult to get under low stand

Now the ball starts rolling. I'm lookin' for a new aqeous cleaner. Do I really need chemical cleaners or saponifiers, surfactant etc. for an Aqeous Cleaning Machine in removing OA or Water Soluble flux from under my 1.27mm Pitch BGA down to 1mm Pitch

Hey guys - our lab has some data and photographs available for the MS2 for use in wave solder from some of the studies we have performed for P Kay. There are other versions being studied, but that is the only version available to market currently.

I was able to escape from Riyadh last week to attend APEX. PK Metals actually had a booth where they did a live demo. They had a working solder pot with dual wave, and demonstrated how their material acts as a barrier to oxidation, which causes dro

Let me give some information on the use of MS2. The average wave solder machine will use one liter per five day week per 8 hour shift. The usage can vary + or - 20%. Instead of removing 6 to 10 Lbs of dross every 3 hours you will have to remove 100 M
