I've soldered things (in the broadest sense) for years but this will be definitely the smallest/most cramped part up to now. The goal is basically to revive the already modded arduino mega. The 'learning SMT rework' is just for fun.
First thing will be google for a few day, then destroying some old motherboards. Then i will decide if i will do it by myself or look for someone else.
Thanks for the tip on flux.
Jeroen.
