Ⅴ. Story about PC board

When you assembled the controller of AIR SHOOTER, you used PC board, didn't you.

All electric machines have PC board surely.  Let's talk about this PC board.

1. What is a PC board?

2. Where PC board is used?

PC board is formally called as "Printed Wired Board," It is formed not to move the material

that lets through the electricity, to board surface of the way that let electricity go through.

Actually, the electric circuit usually see, electric parts and switch have installed with.

Normally, we call it as "PCB."

By the way, why do we need PCB?  Because we don't have to use vinyl wire to wiring, so

that will be small and light.  Moreover, if there are many wires, it causes many mistakes.  And

vinyl wire might be cut sometimes.  PCB solves this problem as well.

You may hard to find the electric machines that is without a circuit board.  However,

circuit board has some electricity, to avoid electric shock, circuit board is installed

to the place that is uneasy to touch.  For example, let's look at video from side and

back.  You can see circuit board from crevice of radiation.  The circuit board has

many electric parts, to act as video from these electric parts.  If you see electric 

machines, there are smaller and bigger size of circuit.  By the way, if we make circuit

more smaller, what is going to be?  Of course, parts are also smaller size.  Then these

parts become IC that you know well.

・

Printed Wired Board (PWB)

・

PCB is used for many things.

・

Printed Circuit Board (PCB)

If PCB

Computer has many
circuit!!

IC is also PCB.

Messed up 

Clear!!
