  1. I tried this a year or two ago, and I did not have much success. A few things though, do not use thin copper wire as it will not work. You need a lot of contact area between the iron and the copper wire, hence him using such a tip. This means you need a iron capable of pumping out a reasonable amount of heat, of which most of us do not have.

    Though, this is still an awesome idea regardless! :P

    1. If you use lots of solder to add thermal mass you can use a thinner copper wire. You can even use to pull the chip away as the wire isn’t very hot (compared to this thick one :D)

      I used this method before getting a hotair. IMO my best investment in tools for years!

  2. use a lighter or small blowtorch to heat the wire instead of a beefy soldering iron. Maybe you can even heat the wire up on the stove first then apply it. Remember to use plenty of flux,

  3. Great idea.

    I used a #12 AWG gage wire, with a 60 watt pencil iron.

    To increase surface, I flattened the wire in a bench press, and leveled with a hammer and some sanding to forma an “square” wire; with it, I was able to remove the IC effortlessly, but it didn’t remove as much solder so I have to later clean the IC leads by hand.

    Then I tried the round wire and that did the trick, the round profile absorbed much of the solder by capillarity and the leads were clean.

    For both runs, I used the iron itself to clean the PCB.

    As it has mentioned, use a lot of flux, but be carefull to remove it clean afterwards.
