You probably shouldn’t look up what most solder is made with, then.

Lead never went away, and it never will. It just stopped being put in things like gas and paint.

  Leas-free solder is now the standard due to RoHS, at least in Europe. It doesn’t stick as well as Pb-Sn solder though, annoyingly.

    The transition to lead free solder (and lack of experience using it) led to the XBox 360 red ring of death issues, Playstation 3 yellow light of death, and nVidia 8000 series no video failures.
    
    And indeed the transition happened a long time ago.
