HOW TO SOLDER

SOLDERING IS THE PROCESS OF PERMANENTLY FUSING TOGETHER ELECTRONIC PARTS. IT INVOLVES MELTING A FILLER METAL ALLOY, CALLED SOLDER, BETWEEN TWO OR MORE COMPONENTS (SEE FIGURE D-1).

This process not only physically bonds the parts together, but also electrically connects them. Unlike using a breadboard, soldering is permanent. Over the course of your adventures in robotics, electronics, and Raspberry Pi, you will come across components that you need to solder (for example, wires onto motor terminals), so it is a key skill for you to learn and practice.
