We've started off with Kester 951 'no-clean' so far which is alcohol based I believe. It seems to do very well with foaming, activation and low residue, but if we can move to water based and get good results that would be great. The 951 flux and thin

The confusing thing is we are doing the same thing we've been doing for years, same flux levels, same procedures, etc. so you would expect the same results. The only difference is the new bottle of 951, but Kester insists there isn't a problem with

We are going to be using a no-clean paste (smt)and no clean wave solder flux on a small pcb we will be doing here soon. As far as the wave process, should i purchase a new fluxer stone for the no-clean. Should I also purchse the recommended thinner o

Hello, We are buying a Vitronics-Soltec wave solder machine with a spray fluxer to replace our old Econopak that has a foam fluxer. Currently we thin our flux (Kester 951) in the foam fluxer per Kester PS-20 and PS-22 test kits with kester 110 thinn

We've got a Novastar 12S wave solder machine and we've been using Kester 951 flux for years with no problems. We just got a new bottle of 951 and it does not foam correctly (thin foam with lots of large bubbles). After a lot of back and forth with

I am looking at two different type fluxes, Kester 951nc and AIM 264-5nc. The two seem to be comparable, but the Kester is listed as an ORL0 and the AIM as a ROL0. My product builds are all military and I have been dictated to use only ROl0 flux. I kn

We are a small CM doing mostly prototype and small production runs SMT and PTH. We have an old Hollis machine works well when we need it. The foam level does not come up to the board level, even with the air cranked up full. We are using a synthetic

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

Jake, The No-cleans on the market, to me, still aren't as good as OA and water wash. But they have gotten better. The type of No-Clean flux and paste to use really depends on each individual assembly, the machines used, settings, and the environme

Also, I was beginning to think that the humidity level in the facility was a factor.. but I don't believe that's the case.. as this condition seems to occur regardless of the humidity level.. Equipment being used is as follows.. Metcal BGA 3500
