A PCB (Printed Circuit Board) is a flat board made of non-conductive material, such as fiberglass or plastic, on which electronic components such as microchips, resistors, capacitors, and transistors are mounted and connected by thin copper traces that are etched onto the surface of the board.
PCBs are widely used in electronic devices, ranging from simple devices such as calculators and remote controls to complex systems such as computers and smartphones. They provide a compact and efficie
