This board was faulty for some undetectable reason so we need to pull the IC off, clean up the PCB and the IC and then mount the IC back on. This video shows heating up the four sides with a circular motion of the air gun and slightly lifting on the IC. We use lead free solder paste so it takes a bit of time for the solder to release. Notice I am not lifting hard enough to raise the PCB - give the IC time to let go of the PCB on its own. www.SparkFun.com
