Impact of Printed Circuit Boards in India 2021

Impact of the Advent of Printed Circuit Boards

The printed circuit board is one of the most amazing creations in the world of electronics. Imagine that many large machines today could be controlled by a very small integrated circuit. Before, electronic circuits fill spaces as large as a room.

Printed Circuit Boards

Due to technological advancements, the circuits were reduced to become as high as a door, and then became as small as a chair. With the advent of printed circuit boards, electronic circuits were reduced to as small as 3-5 inches or even smaller.

Computer technology benefits the most from the advent of printed circuit boards. Due to integrated circuits, logic, arithmetic, and computer memory can now be handled with a single chip called a microprocessor. Modern microprocessors can be made to be no larger than a finger. This is surprising, considering that computer memories are formerly stored in a room where the components are larger than a human.

Reduction in size of integrated electronic circuits and machines has interconnected benefits.

One is the introduction of mobile machines like laptops, cell phones, and other smart devices. Data can also be stored on USB flash drives, which are no bigger than a finger. SD cards inserted in smartphones are as small as nails.

The increased processing speed is also attributed to the reduced size of the circuit. This is due to the decrease in the distance that the electric current travels. The components of traditional electrical circuits are connected via cables. Each electrical component is separated from other components by the meter.

That means that the currents reach the other components more slowly, but not more slowly than most would think. In an integrated circuit, on the other hand, current travels from one component to another by micrometers. Taking this distance into account, the speed at which the signals are transmitted from component to component increases considerably.

Finally, the decrease in energy consumption is a major benefit brought about by developments in integrated circuits. The components of traditional circuits are maintained by high voltages, while integrated Printer circuits Boards only require low voltages (not enough to impact a human).

To understand the efficiency of printed circuit boards versus traditional wiring system, take a look at a simple electrical circuit. A simple electrical circuit is made up of a battery, cables, and a light bulb. The negative charge flows from one side of the battery.

This charge flows through the wires and reaches the light bulb. Once the charge reaches the filament (a thin wire) of the bulb, it heats up and lights up. The charge continues to flow down the other wire until it reaches the other side of the battery. The same principle could apply to a more complex circuit, although the current may not flow one way.

In traditional circuits, the components (not a light bulb but diodes, capacitors, resistors, transistors, etc.) have distances from each other, but are also connected by cables. On the other hand, in integrated circuits, the distance between components and cables is totally absent. Each component is mechanically and electronically connected by the printed circuit board.

Most of a printed circuit board, called a substrate, is made of non-conductive materials like cotton paper, plastic, or fiberglass. The substrate can firmly hold the components, each at a very close distance from each other. As a non-conductive material, the substrate does not allow current to flow freely within it.

Copper tracks or tracks are etched on top of the substrate. These tracks serve as conductive metal pathways through which electric current flows. This replaces the role of cables in an integrated circuit.

The components in an integrated printed circuit boards are very small. The redesign and downsizing of these components are once again attributed to the advent of the printed circuit board. Each component has metal or lead tabs that are used to connect to the copper traces.

Today it is almost impossible to think of a more efficient wiring system than printed circuit boards.

Electronic gadgets these days use printed circuit sheets, or Printed circuit board, in performing their assigned capacities.
