How Printed Circuit Board is made?

Introduction:

The development of Printed Circuit Board is from 1850s to nowadays, which has been more and more influencing on social life, even though it is just a part of electronic products. And we will have a more closely relationship with them in future.

What is Printed Circuit Board?

A printed circuit board, or PCB, is a self-contained module of interconnected electronic components found in devices ranging from common beepers, or pagers, and radios to sophisticated radar and computer systems.

The classification of Printed Circuit Board:

   There are three major types of printed circuit board construction: single-sided, double-sided, and multi-layered.

How Printed Circuit Board is made?

Printed circuit board processing and assembly are done in an extremely clean environment where the air and components can be kept free of contamination. Most electronic manufacturers have their own proprietary processes, but the following steps might typically be used to make a two-sided printed circuit board.

1. Design

2. Making the substrate

3. Drilling and Plating the holes

4. Creating the printed circuit pattern on the substrate

5. Attaching the contact fingers

6. Fusing the tin-lead coating

7. Sealing, stenciling, and cutting the panels

8. Quality control

9. Packaging

The future of Printed Circuit Board

The miniaturization of electronic products continues to drive printed circuit board manufacturing towards smaller and more densely packed boards with increased electronic capabilities. Advancements beyond the boards described here include three-dimensional molded plastic boards and the increased use of integrated circuit chips. These and other advancements will keep the manufacture of printed circuit boards a dynamic field for many years.
