Holly et al,
        There are several non-rosin based fluxes available. This company should 
check with his/her flux/solder supplier. Once they change to the non-rosin based
flux, they can then deflux the boards with hot DI water as we do.   Lee Wilmot

Subject:  solder flux residue
     
Some fluxes contain a "rosin" as one of the active ingredients. 
Apparently this rosin leaves a residue, which must be removed after the 
solder is applied. A small company in Colorado is currently using a = 
vapor
degreaser with perc to remove this residue. Does anyone have any 
experience with any safer alternatives?=20
