Dreamy It sounds like you are having fun in your new job. Saponifier. Alkaline chemicals, added to water, that convert rosin/resin flux residues in the water to soluble soaps. Generally, saponifiers are better if used in an aggressive spray-in-ai

Your copper corrosion is not good. It indicates that you have not done a good job in cleaning. [We assume this is a medium green color, not unlike the color of the solder mask on your board, that is almost like a translucent lacquer; rather than th

Hey Russ I hate to say it but you switched from Indium for no reason! If you were getting residue then your oven profile was off! Your flux should have burned off if it was done correctly, that's the purpose of "no-clean".

Thanks for your feedback. I definitely agree with your viewpoints. Can you send across any documents/papers through e-mail or post them on the smtnet which clearly describes the HARMFUL EFFECTS OF WHITE RESIDUES. My customer's only apprehension is

Good Morning, I think that the use of No clean at SMT and the use of WS at wave is counter productive. For the most part, you will get better results using WS at SMT. If you use No Clean, and then are forced to run this thought a water wash as a req

I am looking for data / info on how flux may contaminate the solder in a Wave. I have a customer who requires a no clean process. Our wave is equipped with 2 separate fluxing systems and I would like to use OA in one and the No Clean in the other. Th

That's OK, as long as you didn't say breading, I knew what you meant. Well, for a quick fix try placing Kapton tape over the gold. It's not a cure, but gets you product. Next try putting a couple of non-screen printed boards thru the oven and se

in other words- who gets stuck with the latrine duty? (have seen American Graffiti, where the "effluent" was burned off with diesel fuel, Lord help the person who got stuck downwind!) The thought of having to swab a tube with some sort of cleaner ma
