What Is The Name Of Printed Circuit Board In Computer

What Is the Name of Printed Circuit Board in a Computer?

The printed circuit board (PCB) is one of the most important components of a computer. It is a flat, rectangular board made of fiberglass or other insulating material that is covered with a thin layer of copper. The copper traces on the PCB connect the different electronic components of the computer together. The name "printed circuit board" comes from the fact that the copper traces are printed onto the board using a process called photolithography. This process involves exposing a light-sensitive chemical to a pattern of light, which then transfers the pattern to the copper. The PCB is an essential part of the computer because it allows the different components to be connected together. Without the PCB, the computer would not be able to function. ### History of the Printed Circuit Board The first printed circuit boards were developed in the early 1900s. These boards were made of paper or cloth and were coated with a thin layer of metal. The metal traces were then etched onto the board using a chemical process. In the 1940s, the first plastic PCBs were developed. These boards were made of a material called phenolic resin, which was resistant to heat and chemicals. Phenolic resin PCBs were used in the early computers, such as the ENIAC and the UNIVAC. In the 1950s, the first copper-clad PCBs were developed. These boards were made of a material called fiberglass, which was stronger and more durable than phenolic resin. Copper-clad PCBs are the type of PCBs that are used in most computers today. ### Types of Printed Circuit Boards There are many different types of printed circuit boards, each with its own set of features and applications. Some of the most common types of PCBs include: *

Single-sided PCBs:

These PCBs have copper traces on one side of the board only. Single-sided PCBs are the simplest and least expensive type of PCB. *

Double-sided PCBs:

These PCBs have copper traces on both sides of the board. Double-sided PCBs are more complex and expensive than single-sided PCBs, but they can also be more compact. *

Multilayer PCBs:

These PCBs have multiple layers of copper traces. Multilayer PCBs are the most complex and expensive type of PCB, but they can also be the most compact and efficient. ### The Importance of the Printed Circuit Board The printed circuit board is an essential part of the computer. It allows the different components of the computer to be connected together and it provides a platform for the components to be mounted. Without the PCB, the computer would not be able to function. ### Conclusion The printed circuit board is one of the most important components of a computer.
