The following are the advantages and disadvantages of printed circuit boards.
Advantages
- Compact size
Because of technological advances, VLSI (Very Large-Scale Integration), GSI (Giga Scale Integration), and ULSI (Ultra Large-Scale Integration), lakhs and crores of components can be put into one single IC, which can be used on a PCB.
- Lightweight
Materials used for PCBs are very lightweight, and even the weight of components is very low. When you use SMD (Surface Mounting devices), this weight goes even lower.
- Cost-effective
In the mass production of a PCB, it becomes super cheap and affordable
Disadvantage
- Repairing the problem
PCB cannot be repaired to the root level because of the complexity involved. You can use new components to change older ones, but deep troubleshooting is very difficult, and not everyone can do that. It requires a high level of expertise.
- The initial machinery cost is high
The cost of PCB manufacturing machines is very high, so the initial cost is very high.
- Low modification possibilities
PCB designs are very rigid and have very little possibility of modification as such. On the other hand, if you have made something on a breadboard, you can modify the design very easily.
