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

Bruno The real question about your troop using Kester 951 wave solder flux on boards is: how is the flux applied and controlled. See, when you apply this flux with your wave solder fluxer, it is ideally applied in a metered fashion with your fluxer

We recently changed to an Amtech no clean paste and flux that is washable. So far excellent results. Far superior to the water soluable paste we were using. Fewer solder balls, longer life in printer, boards can be left up to 5 days and still come

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

Thank you guys for your help, I do not clean any on my assemblies who are build by the SMT an wave soldering department, we do used liquid fluxes Kester 951 and cored wire keester 245, usually it�s for batteries connector, led, terminal and wire rap

Thank Rob those are our own product, try few test by not clean some PCB never had any issue except on compoment under faraday cage. Did you know any norm that could persuade my boss and the R&D department that cleanning no clean is a waste of time. T

Hi I will like to know what do you think about cleaning hand solder, my employee spend about 25% of they time to brush they hand solder with teddy pen cleaner, we used no clean solder wire. It�s not been the first time that I try to eliminate those c

Our PCBs manufactured with no clean flux have a waxy film on the board...is this normal? Our contract manufacturer recently switched to no clean from water wash. Thanks Carl
