This phenomenon is caused by a high amount of halogens (Cl, Br etc.) used in the flux activators or in the flux surfactants. We've seen effects creating all colors of the rainbow. Changing to No-Clean (halide-free) will eliminate this color effect.

Try an intermediate paste like Loctite/Henkle 218. It's design is to be used in a mixed lead/lead-free process.

Dave, Thanks - I couldn't agree with you more. Unfortunately, our "bean counters" have a different frame of mind.
