High Voltage PCB Applications

What is the Clearance in a High Voltage PCB?

Clearance is the minimum distance between two conductor traces.

This distance is not taken by measurements but through the line of sight (visibility through the air).

Usually, the clearance value varies according to the materials used in high voltage PCB.

Clearance is kept as per structural and design requirements of the printed circuit board.

How High Voltage PCB is Designed?

As the name suggests, a high voltage PCB is designed according to the principles of the high voltage supply.

Some of the most common attributes that should be present in its design are as follows:
