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
