Electronic parts are then attached to this base using a conductive material . The circuits etched into the board allow electricity to travel from one component to another, so the parts can work together.

Boards carry many different parts which are connected together in electical circuit to do their different tasks. The most common circuit boards are called PCBs (printed circuit boards) and are most commonly mass produced ready for a specific job. Some circuit boards are made plain so a person can build their own for a particular electrical task. Most things that use electricity have at least one circuit board inside of them that makes them run.
