If you have never soldered before,there are guides on the internet andeven on iFixit that make it easy tolearn. We suggest becoming familiarwith soldering before proceeding.

Now we are ready to begin thesoldering process. You'll need asoldering iron, solder, anddesoldering wick.

Clean the soldering iron by melting asmall amount of solder onto thesoldering iron's tip. Then wiping thetip of the soldering iron on a dampsponge.

Place the desoldering wick on top ofthe existing solder ball.

Hold the soldering iron in place untilthe solder melts into the wick.

Repeat the same procedure on theremaining connector.

Pull the desoldered wires off of thecircuit board. They should come offwith little to no resistance. If they donot come off easily, remove moresolder from the contact points withthe wick.
