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
