Tin/Lead solder with acid flux [usually external, not core] was the
norm for copper plumbing for years. They switched to lead free
solder for health concerns [I've always thought silly] sometime in
the 90s. The flux used is still very reactive; I'm not sure exactly
what is it or how acidic.
And yes, acid flux will ruin electronic components. On plumbing
you're supposed to wipe it off the outside, and any inside will be
flushed away.

That looks like some really snazzy stuff! I hate to think what they
charge for it!
