1876Lead Free Solder

      Greetings all:

      The electronics industry is in the process of changing from the
      traditional lead tin solder alloy to a lead-free alloy which is mainly tin.

      Soon, all consumer electronics will be lead free. This is part of a
      law in Europe and a movement called ROHS (reduction of hazardous substances).

      I will guess that all the chargers over 2 years old use lead / tin solder.
      If you go to the electronics store ask for lead / tin alloy.

      I do not know how difficult it is to mix the two kinds of solder, but I believe you need to get the lead free stuff a little hotter. In all cases, a clean, well tinned soldering iron is mandatory for a good job. If you are soldering large items, you will need an iron big enough to quickly heat up your joint. But, like Tom said, avoid acid flux!

      All there any electronics technicians out there who have hands-on experience with this stuff?

      AFAIK, all electronic solder is an alloy of lead and tin. Plumbing
      solder is lead-free, but you don't want to use it on electronics because
      it uses an acid flux that will destroy the circuitry. Electronic solder
      uses non-corrosive rosin flux. There's also silver solder for jewelry
      and such, which is much stronger than lead solder but it typically also
      uses acid flux.
