WHAT IS BENEFIT OF GROUND PLANE IN PCB DESIGN ?

In this tutorial we are going to learn about WHAT IS BENEFIT OF GROUND PLANE IN PCB DESIGN ?

· Low inductance

· High capacitance

· Low EMI susceptibility

· Low EMI radiation

· Large PCB land area

· Always try to make design double and multi layer

· Signal track routing can be difficult

A ground plane provides several benefits:

• GND is frequently the most common connection in the circuit. Having it continuous on the bottom layer usually makes the most sense for circuit routing.

• It increases the mechanical strength of the board.

• It lowers the impedance of all GND connections in the circuit, which reduces undesirable conducted noise.

• It adds a distributed capacitance to every net in the circuit, helping to suppress radiated noise.

• It acts as a shield to radiated noise coming from underneath the board.
