PCB advantages and disadvantages

The PCB stands for the printed circuit board. This board is a very vital part of modern electronic equipment. Printed circuit board consists of a very large number of passive as well as active components required. The components are connected from side to side with traces on the board. It is absolutely to develop very large circuits on small printed circuit boards with the availability of very small-sized electronic components. Let us have a deep insight into the advantages and disadvantages of the printed circuit board to know more about it. 

Advantages of PCB :

  • PCBs has a low cost, mass production can be achieved at a lower cost.
  • It is Re-workable.
  • Widely available.
  • Excellent shelf life
  • This board gives low electronics noise.
  • Compact size and saving of wire.
  • Inspection time is reduced because PCBs eliminates the probability of error.
  • This board takes less time in assembling a circuit as compared to the conventional method.
  • In this design, there is no chance of loose connections or short circuit.
  • If in case of any damage, it is very easy to check and replace the particular failure components.
  • Printed circuit board design to offer uniformity of electrical characteristics from assembly to assembly.
  • The location of the electronic part is fixed and it is easy to simplify components identification and maintenance of equipment.
  • Component wiring and assembly both can be mechanized in a circuit board manufacturing facility.
  • All of the above factors bring reliability in the performance of the circuit.

Disadvantages of PCB :

  • Uneven PCB surfaces finish.
  • Not good for fine-pitch.
  • It contains lead.
  • Thermal shock.
  • Solder bridging.
  • Not easy to repair once damaged.
  • It can be used for a specific circuit.
  • We cannot be updated, once printed.
  • Plugged or reduced.
  • Redesigning is required for one type of circuit operation.
  • The etching process generates chemicals which are a harmful effect on the environment.
