+=== Desoldering the chip using a heat gun and aluminum foil ===
 You can also use a piece of aluminum foil and a house hold heat gun for desoldering the chip. Most heat guns have a high and low setting, you will only need the low setting. The whole process only takes a few minutes. Blow the heat at an angle to the side of the chip at the solder joints going around the chip in a circle (never directly on top).
