Bonus! You thought you were just learning how to through-hole solder, but Included with this kit is a complimentary intro to surface-mount soldering. Surface-mount soldering is commonly used to attach batteries to circuit boards in some devices, such as iPods.

Set the tip of your soldering iron on the large copper negative solder pad. This will allow heat to conduct through the solder pad, making soldering easier.

Touch your solder to the tip of the soldering iron and keep feeding it until you have a smooth, convex solder dome on the copper pad.

If the solder doesn't come out quite right, you can always use the iron to melt it again or add more solder.
