Another up-vote for desoldering alloy.? I've used this product

with very good results.? I've had to replace ATmega328 microcontrollers twice, and each one involved harvesting a donor chip from a development board since you currently can't buy these MCUs at reasonable prices and with quick delivery.

Full story here:
???? I fried my ATmega328p (Fixed thanks to KI6NAZ's story)

After removing a bad chip with the alloy I'm careful to clean the PC board pads up with solder wick, to get rid of the remaining desoldering alloy.? And since I had to harvest an ATmega328 from a donor board I cleaned up the pins of the replacement chip using solder wick.

Works well and saves me from buying a hot air rework station and having Yet Another Rarely Used Tool around.
