Here we are: the moment of truth. It's time to get that solder flowing.

Set the tip of the soldering iron on the two parts to be connected. In this case, that's the resistor lead and the copper trace on the circuit board.

Touch your solder to the tip of your soldering iron to melt it onto the joint. Don't hold it there for more than a second or two.

Quickly, but not frantically, pull both the soldering iron and the solder away from the joint.

Your solder joint should be shiny and conical, and not expand beyond the copper trace.
