Hey,

You'll need to start off by getting a good soldering iron, something along the lines of a Hakko, then you will need decent flux, and decent solder at different widths, for smaller stuff go with the thinner soldering wire, try and make sure it's multicore solder as that also contains flux in the solder and helps a lot. A good reflow station will be needed for sure. You will definitely need a decent microscope to, you can't do it by eye, as the chips are so tiny! If you do plan on soldering a lot, you'll more than likely need a fume extractor, as the fumes from soldering are bad for health.

Hope this has helped. :)

Tools only:

Hotairstation/Reworkstation

Soldering Iron

Solder

Flux

fine quality tweezers (also important)

Changing the u2 chip is one of the easier IC's to change but still not the place to learn micro soldering.

Practise and get to know your tools on dead boards until you know how to remove parts without destroying the whole board.
