Depends on the alloy, tin/bismuth will melt around 140C. I would've expected over 180C to be necessary as well though. Sn63Pb37 is very common and melts at 180C

I read somewhere the xbox gpu problem was a result of the lead-free solder used to meet environmental regulations.

    You're blaming RoHS on Obama?

      Must have been fond of lead paint as a kid.

If your electronics are RoHS compliant (they are), there is no lead.

  Apple's laptops are RoHS, so the melting point of that lead-free solder should be even higher than 183 C.

    And all the joints look like cold solder joints instead of nice, shiny but toxic, lead-filled goodness.

      I use lead-free solder for hobby work. A good joint is still shiny as you'd expect. I basically notice no difference, except the need for a higher working temperature.
