Sure do, it's from the paste that gets squeezed under your R's and C's. This paste is now on your mask and during reflow, wants to move off the mask. Unfortunatly, it follows the flux residue to the side of your component. An easy fix is to use th

We had a similar application to rewash excessive flux residues through a chemical wash, steam clean, and DI rinse. We currently have an inline cleaner. Can you comment what kind of steamer (made and manufacturer) is being referred to in this discussi

RA and RMA flux residues are "sealed" in a hard, glassy coating that do not require cleaning in many end-use environments. That being said, automotive, automotive underhood, and deep well are in that [ascending] order the three most burtal environme

The manufacturer confirmed that it is humidity - the solder paste is too sensible to humidity. Now I tried Koki solder paste with good result. But, it does leave flux residue in good quantity. Does anyone have experience with Koki solder paste?

Aqueous cleaning solutions using saponifiers and surficants can sometimes be used to clean NC flux residues. Search the fine SMTnet Archive for background and supplier suggestions.

Factors that affect the solder joint quality are *envirinmental condition(i.e.,humidity) *contamination *Flux residues *all of the above

We've only seen it done by accident, and the result was a lot of white flux residue. You do need to make sure you get it all off, and to do so most likely means using a saponifier like sara suggested.
