[Diy_efi] Surface mount

[Bevan Weiss]

I would very much recommend the LQFP.  Trying to work with the LFCSP is a 
bit tough unless you are pretty skilled with a rework station.  Certainly 
not something that can just be soldered with your standard pencil tip.

LQFP packages are pretty good for hand soldering.  Not as nice as a through 
hole dip.. but then they're generally much better devices, so worth the 
extra effort.
