what is a pcb

A PCB, or printed circuit board, is a fundamental component in electronic devices that provides mechanical support and electrical connections between electronic components. It is a thin board made from non-conductive material, such as fiberglass, and features conductive pathways, usually copper, that allow electricity to flow between the different components on the board. PCBs are essential in the functioning of almost all electronic devices, including smartphones, computers, and medical equipment. They enable the seamless integration of complex electrical systems and provide a stable platform for electronic components to be mounted on. PCBs also offer great flexibility for circuit designs, allowing for intricate and compact layouts that maximize efficiency and performance. In summary, PCBs play a crucial role in the design and manufacturing of modern electronics, providing a reliable and efficient way to connect and support electronic components.
