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- A circuit board in which the interconnecting wires been replaced by conductive traces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