On most two-terminal SMD parts (resistors, capacitors, etc.), the solder terminal on each end extends on both sides (top and bottom). So the way I generally remove them is to tin the top of each contact with a little solder and then lay the soldering iron tip across the top of the entire part so that it heats both ends at the same time. Once the solder melts, you can push the part off the pads with a toothpick, Exacto knife, whatever. > Good light and your favorite magnifiers (if needed) to see clearly are > essential. In my experience, being able to see the darn thing clearly is really the key to successful SMT work. I have a binocular microscope with built in light that I bought brand new for about $300. Whatever you use, make sure to have a bright light, and some form of magnification is very useful for those of us with middle-aged (or greater) eyes.
