Proper soldering iron wattage for working with uP scale electronics?
Selecting an iron that is too low in wattage requires the user to apply heat for a longer amount of time. This actually makes the surrounding area heat up more than if a more powerful iron were used to heat the component. Although a 25W iron will likely do this job without any trouble, and 80W temperature controlled iron is much more versatile. Make sure you use flux, and tin the iron afterwards.
