PCB (Printed Circuit Board)

A Printed Circuit Board (PCB) is a flat, rigid surface that connects electronic components like chips, resistors, and capacitors using thin lines of conductive material, typically copper. It serves as the foundation for assembling electronic devices, providing both physical support and electrical pathways to ensure components work together correctly. Think of it as a specialized map that guides electrical signals between parts, allowing complex devices like smartphones, computers, and appliances to function reliably and efficiently without messy wires. PCBs are essential for compact, durable, and organized electronic systems.
