A printed circuit board (PCB) is a non-conductive board that mechanically supports and electrically connects electronic components using copper tracks etched onto laminated sheets. PCBs can be single-sided, double-sided, or multilayer. They were first developed in the 1930s and are used to build circuit board assemblies, with common types including single-sided, double-sided, and multilayer boards.

2. Introduction to
PCB
Printed Circuit Board can be shortly called as PCB
PCB is a non conductive substrate that mechanically supports and
electrically connects the electronic components using tracks, pads and
other features etched on a laminated copper sheet.

3. A PCB populated with electronic components is called a printed
circuit board assembly (PCBA)
PCBs can be a Single-sided (one copper layer), Double-sided
(two copper layers) and Multilayer.
PCBs were first developed by an Australian engineer Paul
Eisler

4. Types of Boards
Bread Board
General Purpose Board
Printed circuit Board

5. History of PCB
Dr. Paul Eisler(1936)
Mr. Albert Hanson(1903)

6. Types of PCBs
There are mainly three types of PCBs
 Single-sided PCB
 Double-sided PCB
 Multilayer PCB
