What is a printed circuit board?
Q: What is a printed circuit board?
A: A printed circuit board (PCB) is a board made for connecting electronic components together.
Q: What are circuit boards used for?
A: Circuit boards are used in almost all computers and electronics today.
Q: What is a PCB made of?
A: The "card" is made of a material that does not conduct electricity, usually fiberglass.
Q: How does a PCB allow electricity to travel from one component to another in electrical circuits?
A: Usually copper is etched (set in thin lines) inside the board between the layers of fiberglass or on the surface of the board. The metal etched into the board allows electricity to travel from one component to another in electrical circuits.
Q: What are flexible circuit boards?
A: Flexible circuit boards are those that are made thin enough and of the right material to flex (bend).
Q: What are rigid-flex boards?
A: Rigid-flex boards are those that combine the features of the rigid boards and flex boards, hard at some points and bendable at some other points.
Q: Do most things that use electricity have at least one circuit board inside of them?
A: Yes, most things that use electricity have at least one circuit board inside of them that makes them run.
