Printed Circuit Boards, or PCBs, are essential components in most electronic devices. They provide a platform for connecting various electronic parts, such as resistors, capacitors, and microchips. Made from materials like fiberglass and copper, PCBs have intricate pathways that allow electricity to flow between components, ensuring the device functions properly. The design of a PCB is crucial for the performance of electronic devices, from simple gadgets like calculators to complex systems like computers. Engineers use specialized software to create these designs, which are then manufactured to precise specifications. This technology enables the compact and efficient assembly of electronic circuits, making modern electronics possible.
