One example of a multilayer PCB is a computer motherboard. A computer motherboard is a complex electronic circuit board that serves as the central hub for connecting various components in a computer system. It typically consists of multiple layers of conductive traces, power and ground planes, and signal layers.

A computer motherboard requires a multilayer PCB design to accommodate the numerous components and their interconnections. The motherboard incorporates various layers for different purposes, such as routing high-speed signals, providing power and ground distribution, and isolating sensitive circuitry.

The signal layers of a motherboard carry the electrical connections between the CPU (Central Processing Unit), memory modules, expansion slots, storage devices, and other peripherals. The power and ground planes provide stable power distribution and serve as a reference for signal integrity.

Additionally, the motherboard may include internal layers for specific functions, such as impedance-controlled traces for high-speed interfaces like PCIe (Peripheral Component Interconnect Express) or SATA (Serial ATA). These internal layers are carefully designed to meet the specific requirements of the computer system.

Overall, a computer motherboard is an excellent example of a multilayer PCB due to its complex circuitry, high component density, and the need for reliable signal transmission, power distribution, and noise reduction.
