PCBs
PCBs
What is it?
-
PCB is short for Printed Circuit Board
-
A printed circuit board (PCB) is the board base for physically supporting and wiring the surface-mounted and socketed components in most electronics.
-
A good example of a PCB found in all computers today is the computer motherboard.
-
In a desktop computer, the motherboard is the largest circuit board that all other boards and devices connect to and communicate with each other.
A PCB is made of plastic or fiberglass that holds ICs and other components.

How are PCBs made?
-
Photolithography is the standard method of the printed circuit board (PCB) and microprocessor fabrication.
-
The process uses light to make the conductive paths of a PCB layer and the paths and electronic components in the silicon wafer of microprocessors.

-
Electronic components are typically placed by machine onto a finished PCB that has solder dabs in place.

-
There are several other ways to design PCBs.
-
Iron on Glossy paper method.
-
Circuit by hand on PCB.
-
Laser cutting edge etching.

Types of PCBs
PCB
Single Layer
-
Board has one copper layer.

Double Layer
-
two copper layers on both sides of one substrate layer

Multiple Layer
-
outer and inner layers of copper, alternating with layers of substrate

Uses
-
PCBs are used to design an almost electronic circuit like:
-
RAM stick.
-
Mother Board
-
Remote
-
Monitor
-
Radio
-
Keyboard
-
Industry application
-
Consumer Appliance
