> I remember some brief discussion here some time back re: flux removal and some Non-amine rosin flux need not be cleaned off. Rosin and wax solutions are one of the oldest 'plastic' substances known and in continuous use as flux and as models in art and technology since the bronze age probably. The only requirement is the usual one: it has to be clean (no amines, and no other conductive inclusions). As long as the flux says 'no-clean' flux you can trust it to be so.
