I would suggest one change: avoid lead-free solder, use real solder (63/37
solder is best). It works just fine with modern politically correct parts, and
it's much easier to use. I followed this advice from a professional PCB tech a
couple of years ago when working on a fine pitch home project -- she was
absolutely right.
