Printed Circuit Board (PCB)

A Printed Circuit Board (PCB) is a flat, green (or sometimes other color) board that connects electronic components using tiny, precisely placed metal traces. These traces act like electrical highways, enabling signals and power to flow between components such as resistors, chips, and connectors. PCBs provide a sturdy platform for assembling and organizing electronic parts in devices like computers, smartphones, and appliances, ensuring reliable communication and operation. They are essential for compact, efficient, and durable electronic systems, simplifying manufacturing and repair processes through a standardized, integrated design.
