My people said I was needed again here on The Forum. Thanks Mr Head for the goddos on wave soldering. It's a hard process to grasp and not every one nows how to adjust eveything properly. I can tell you regognize expertise when you see it. That s

Really, if you start out from the beginning planning to clean the boards, then DON'T use the no-clean flux! The way that stuff is made, it leaves a hard, low-solubility residue that takes a LOT of effort to get clean. If you plan to clean, use a wa

Hi Rob, I must take issue with your statement �By definition, no clean solder can be not-cleaned�. All no-clean fluxes can be cleaned. Whether or not one cleans no-clean depends on a variety of factors. More than eighty percent of all post reflow

By definition, no clean solder can be not-cleaned. The solder/flux are formulated to result in low ionic-contamination, hence, no cleaning. I have, however, always had at least one customer that requests their no-clean solder get cleaned. No-clean
