Introduction to Printed Circuit ( PCB )

What is PCB

- eletronic board that connect components such as resistors, integrated circuits and connectors.

- A circuit board in which the interconnecting wires been replaced by conductive traces

Advantage of printed circuit board

- Less Error

- Quicker Assembly time

- Greater circuit desity

-  Easy to troubleshoot

*less skills required

*use of automatic assembly equipment

Component of PCB

The base

The Conductors

Type of PCB

• Single-side PCB

• Double-side PCB

• Multilayer PCB

Single-side PCB 

• Has circuit traces and path etched on only one side
• components are placed on the other nontrace side
• wheere the 1st to be develop

Double-side PCB

• PTH
• NON PTH

Multilayer PCB

• Complex and expenside
• More than two printed layer 
• have three or more circuit layer

Classification of PCB

• Consumer PCB (biasa seperti single layer)

- radio ,tv , cheap test

- use less expensive base material

• Profesional board 

- Made better quality  material

- use chip

• Higer reliability boards

- use strategic application

- best chip
