Printed Circuit Boards (PCBs) are foundational components in electronic devices, serving as the mechanical support and electrical connection platform for various electronic components. They are flat, rigid boards made of non-conductive materials like fiberglass or composite epoxy laminate, with thin layers of conductive material (usually copper) etched or printed onto the surface.

PCBs facilitate the assembly and interconnection of electronic components by providing conductive pathways or "traces" that carry electrical signals between different parts of the circuit. These traces are typically created using a process called etching, where unwanted copper is removed from the board, leaving behind the desired pattern of conductive pathways.

PCBs come in various types, including single-layer, double-layer, and multi-layer boards, depending on the complexity of the circuitry and the number of layers of conductive material used. They are essential in modern electronics, used in everything from smartphones and computers to medical devices and automotive systems.

Overall, PCBs play a crucial role in enabling the functionality of electronic devices by providing a reliable and compact platform for connecting and integrating electronic components.
