Da> What kind of solder is used on the SMD in the K3? Leaded or Unleaded ?
And what kind of flux was used.

It is RoHS compliant.

And not to start a another very long thread, what would people suggest for flux when doing mods? I'll use the same solder type. But maybe water soluble flux is not such a good idea for manual rework?

After the board is built, water soluble is not a good idea. The joints will tend to corrode, and I don't like the idea of putting my K3 in the family dishwasher for a complete rinse...

I use plain old tin-lead rosin-core solder for SMT rework on my K3. I sometimes use "no clean" flux rather than rosin core. Depends on which spool is nearer when I do the re-work. But I carefully avoid the spool of water-soluble flux which I use for prototype construction.

The regular solder will alloy with the solder on the board, no problem.
