Compact Size and Saving of Wire. A characteristic PCB includes a large number of electronic components. On a Printed circuit board, the interconnection between the components is made through copper tracks instead of using a number of current carrying wires.


A basic PCB circuit consists of a very large number of passive and active components. All the components are connected from side to side with traces on the board.

Compact Size and Saving of Wire
PCB includes a large number of electronic components. On a Printed circuit board, the interconnection between the components is made through copper tracks instead of using a number of current carrying wires. It makes the interconnections less bulky.
Most of these components are very small in size. It would be close to impossible to connect these components together with wires without the aid of printed circuit boards.
Printed circuit board offers a simple platform to arrange the electronic components in a compressed and efficient way. This compactness allows the creation of big and complicated electronic circuits in small form factors. This, in turn, takes less space in devices.

Ease of Repair and Diagnostic
If in case of any damage, it’s very easy to check and replace the particular failure components. The electronic components and their polarities on a properly designed, printed circuit boards are clearly labeled on the board.

Saving of Time
The conventional method of circuit connections takes much time to connect the components. Whereas the printed circuit board takes less time in assembling a circuit as compared to conventional method.

Movement of components
The most important thing to notice is that all the components on a printed circuit board held fixed to the board. This is done by solder flux which does not allow them to move irrespective of the movement of the board itself.

Tight connections and Short Circuits Avoided
As the connections are made automatically through copper tracks, there is no chance of loose connections or short circuit.

Low Cost
Mass production can be achieved at lower cost.

Reliability
All the above factors bring reliability in the performance of the circuit.
At the heart of each of electronics is a printed circuit board (PCB). It is the foundation of a majority of electronic products today. There are a massive number of applications for PCBs.
A printed circuit board is used to connect electronic components. These are essential parts of all the electronics products that people use at home and work each day.
