Well there is good news and bad news. The bad news is that it is
impossible to solder the chip by hand without creating solder bridges.
The good news is that I did a good enough job to get the chip 99%
perfectly centered on the solder pads, and you can remove the solder
bridges with solder wick without removing the chip from the PC board.


I've seen people recommend this as the preferred hand-soldering
approach for dealing with small-pitch surface mount parts. Don't
worry about creating bridges... use a bit of liquid flux on the pins,
get a nice blob of fresh solder onto the tip of the iron, and then
just gently drag the molten solder-ball along the pins and get them
soldered to the traces. Then, go back over it with solder-wick and a
bit more liquid flux, and wick away the excess.
