Q:

How do you solder?

A:

Quick Answer

For Dummies explains that the key to soldering is to apply heat to the points requiring connection and not to the soldering iron itself. By doing so, the joint is evenly connected on all sides, providing a smooth transfer point for the electric current between parts.

Full Answer

  1. Set up the joint

    Place the pins of the electronic component through the holes in the pad where the solder is being applied. Make sure that no portion of the pins touch any other holes in the pad or any other component ends. The pad is the metallic copper circle that extends through a circuit board at the end of the circuit trace lines that connect components.

  2. Heat up the iron

    Turn on the soldering iron. Allow it a few minutes to heat up to a sufficient temperature to melt the solder.

  3. Heat the joint

    Place the tip of the hot soldering iron against the end of the pin passing through the circuit board and the pad on the side that the component pin passes to. Heat the connection area for a few seconds so that the temperature of the pin and the pad are equal to that of the soldering iron.

  4. Apply the solder

    Pull the soldering iron away from the heated parts slightly, and then touch the solder to the parts to melt the metal over the component pin and pad. A drop of solder is typically enough to make the connection.
