Hi Ivan and All, As you have discovered there really isn't a 'no clean' flux (at least with 'special' cases, yours - Probe; mine - Conformal Coating). Somebody correct me if I'm wrong but you have a couple of choices - clean the probes, clean the boards, or change the equipment/process (i.e.. change the way you test and/or solder $$$). The question I have for the group: Would soldering in an inert environment remove the need for flux all together? I would swear I have seen that mentioned somewhere recently (where o where? - was it PC FAB or maybe Precision Cleaning). Hans Air Force Material Command - We keep them flying! ~~~~~~~~ Hans M.
