Michael, You're right, of course. A major mis-type on my end. What I meant to say is that no-clean fluxes are designed to not _require_ cleaning to meet industry cleanliness standards. Cheers ..rob

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

Hello All, Is Ionic Cleanliness testing using say an Ionograph on No-clean assemblies a valid test? If not, why? I understand factors like PCB cleanliness but is the 1.56ug/in2 IPC criteria valid for no-clean assemblies and can an Ionograph be used

This is one of the most common questions I get asked. Why clean no-clean flux. It was stated earlier that no-clean residues are benign. This may or may not be accurate. It depends on several factors including the reflow process. In a perfect world, t

Wayne, I think Dave and Justin are correct but I would just add my twopennworth: Your customer presumably wants to know if the end-product will be reliable? If he/she wants you to prove cleanliness, ask them for the spec they want to work to and app
