Ken, In my mind there is absolutely no question, hand assemble using Water Soluble flux. A good spray under hot water cleans well. During final assembly or rework I might use a no clean at spots. The only problem is the no clean is VERY DIFFICULT to remove so don't try. It detracts from board appearance. It the spot being reworked is a sensitive analog circuit they rework using Water Soluble. For anything close to fine pitch SMT you should be applying liberal quantities of Water Soluble flux, only way to rework. You can get a little "Water Pick" real cheap. Load it with hot water and you can you can really get down into the nooks and crannies.

What is the best setup for hand soldering as far as solder / cleaner? Rosin core? Water soluble? No-Clean? What cleaner too? I've been using rosin core with various cleaners but I have a hard time with the white residue the cleaners leave. Thanks Ken ______________________________________________________________________ This email has been scanned by the MessageLabs Email Security System.
