India, May 4 -- What Is A Printed Circuit Board (PCB)?

A printed circuit board (PCB), also called a printed wiring board (PWB), is a thin board made of insulating material that has thin layers of metal (usually copper) bonded to it.

These metal layers have etched patterns creating electrical pathways connecting electronic components soldered onto the board. The insulating material keeps the electrical traces from touching each other and causing short circuits.

Ideated by Paul Eisler in 1936, PCBs are essential in all modern electronic devices and have caused a paradigm shift in electronics ever since mass usage began post-World War II.
