By far the easiest method.

In the case of the rt7 (or knife soldering tips for other brands) you get a
fine point that easily handles 30-32 awg wire, and the edge of the tip is a
little over 100 thou long, so for parts 0805 and smaller you just lay the
edge along the side of the component and heat both pads and swipe it to the
side.
