Printed Circuit Board

A Printed Circuit Board (PCB) is a flat board made of insulating material with conductive copper traces etched or printed onto its surface to create electrical pathways. It serves as the foundation for mounting and interconnecting electronic components like resistors, capacitors, and integrated circuits in a compact, organized manner. PCBs eliminate the need for complex point-to-point wiring by providing predetermined electrical connections between components. They are essential in virtually all modern electronic devices, from smartphones to industrial equipment.
