Here's an article our lab has published about green contamination - http://www.residues.com/pdfs/foresite_green.pdf If you are concerned with finding out just what is there and what the cause is, I would agree with davef that it would be helpful for

It could be lots of things. You're not helping to narrow those alternatives. So, consider taking a sample to: * An analytical laboratory. * Teachers in the chemistry department at a local university. Kester recommends the following independent la

What is the make-up of the residue? Is finding this residue new to your standard operation? What has changed?

The water soluble flux residue is staying there because the rinsing temperature it may be too low. The flux needs about 130-140 degrees celcius to become soft. If you are using water soluble flux, as per IPC A 610 standards it needs to be remove comp

I have a customer that is having a flux residue problem after wave soldering. Flux is roaring through the board to the top side and leaving a residue. This is only happening on the flat stamped leads. The round leads are fine. They are using Supe

About one year we have that problem with some of pcbs. Our customers told us about that. Because they can't mounting components on those pcb reason of flux residue. As you know flux not conductive chemical. We didn't change anything before having tha

No clean residues can range in appearance from brownish gunk that looks like tree sap (because it is in some instances) to almost no residue at all. Is this product exposed to a wave soldering process or SMT? I would guess it's a wave process if th

We use hot air leveling (HAL) process in pcb production. HAL process is 3 steps. �n 1. step flux. 2. step is HAL. And 3. step is rinsing. As you know there is mustn't any flux after rinsing operation. Our flux chemical is water soluable. But there ar

Hi, Walter, Why don't you try no-clean flux? We ever met the same condition, later, we changed to no-clean flux solved the problem.
