Removing surface-mounted ICs

The classic way of removing SOJ parts is to use two soldering irons and a
big blob of solder on both rows of pins. The solder blobs heat all the
pins simultaneously and the chip can be slid right off.

Also, you'll be removing the chip without damage -and- you can easily
clean up the PC pads to install a new chip.

It's a great Silicon Valley hack I've see here performed many times.
