While both of those products do make it easier to profile the wave, a standard reflow oven profiler, with some long thermocouples, are all you really need. You can even use the standard Thermocouples and send the profiler through the oven on a traili

I'd like to add something about the ECD product. During a past work term (I'm a a co-op student) in an SMA plant, I worked extensively with the Super MOLE Gold in developing the reflow profiles for high-mix, low-volume production. I was 'married' t

White residue, probably nothing to do with the flux but was more than likely mineral salts from resist cure problem that are only soluble in Mineral Acids. No residue is the best IF resist is good, if resist issue's use low solids Rosin No Clean and

Hi George This is down to the different cure temperatures used during PCB process. No problem with the flux or your settings You should be seeing a waxy greasy oil like substance on the dirtier board. Or the resist has absorbed the flux residues not

We're looking into a new profiler and potentially one of these wave rider tools. I found some old threads, but nothing very recent. We tried the Malcolm tool a long time ago, but we weren't very happy with it. I'm sure I can get a demo unit and co

Glenn, There are both very good VOC-Free fluxes as well as alcohol based fluxes out there. This should be your primary focus if you are so lucky as to have to opportunity to actually select a flux! The use of nitrogen will benefit any no-clean pro

Claude, your not a manager by any chance are you?... you can't charge them for breaking them. Ok so yes there will be poor handling but if your going to fix the problem you have to look at teh route cause of it and fix that. You should be settign up
