Electrical and Electronics Engineering feature image

In this post, we are going to study,

  • What are the advantages of printed circuit board over conventional wiring, breadboard, and components mounting techniques?
  • What are the major disadvantages of printed circuit board (PCB)?

Let’s dive into the explanation,

Advantages (or Pros) of PCB

  1. Printed circuit board finds in compact size. So, this is very easy for the transfortation.
  2. There are very few chances of connected components getting disconnected in the PCB, than in conventional wiring.
  3. PCB designing and fabrication takes less time than making wire connection.
  4. The electronic components are fixed in PCB through the soldering. So, it is easy to simplify components over the PCBA.
  5. The less wiring is required for PCB designing.
  6. The PCB gives good flexibility to place required components and fix them at specific position.
  7. This board is very economical than the PCBA due to less requirements of PCB wiring and components.
  8. It creates less electronics noise.
  9. The troubleshooting, inspection, and replacement of faulty components or connections on PCB is very easy over regular wiring.
  10. Under the short circuit or fault condition, the failure components on PCB can be easily checked through the multimeter. So, it requires less maintanance.
  11. You can get PCB board very easily in the market at an affordable cost.

All these are benefits and reasons for using PCB instead of the conventional wiring, breadboard, and components mounting techniques (such as printed circuit board assembly i.e. PCBA).

Further, read the PCB vs PCBA. You will find a few more advantages.

Disadvantages (or Cons) of PCB

Here are some of the disadvantages of PCB as compared to the PCBA and regular wiring.

  1. Once you prints the cirucit on the PCB board, you can not modify it.
  2. The soldering is a required (must) to connect or fix the electronic components on PCB.
  3. Again for soldering, thermal shock is required.
  4. PCBs contain more amount of lead.
  5. The etching process is very harmful which is required for manufacturing of PCB.
  6. This circuit can be used only for the specific function and feature of devices or systems.

These are the limitations and disadvantages of the PCB as compared to the conventional wiring.
