what is a printed circuit board

A printed circuit board (PCB) is a crucial component in electronic devices that serves as a mechanical support and electrical connection for various electronic components. It is a thin board made of non-conductive material, such as fiberglass, with electrical pathways printed or etched onto its surface to connect the different components on the board. PCBs are essential in a wide range of electronics, including smartphones, computers, medical devices, and automotive systems. They are designed to provide a reliable and efficient platform for the assembly and interconnection of electronic components, ensuring proper functioning of the device. PCBs also contribute to the miniaturization and integration of electronic circuits, making them a vital part of modern technology. With their versatility and functionality, PCBs have become an integral part of electronic manufacturing, allowing for the creation of more advanced and complex electronic devices. They play a critical role in enabling the development of innovative and high-performance electronic products.
