While PCBs for simple electronics with limited functions are usually composed of a single layer, more sophisticated electronics, like computer motherboards, consist of multiple layers. These are what are called multilayer PCBs. With the increasing complexity of modern electronics, these multilayer PCBs have become more widespread than ever before, while manufacturing techniques have enabled them to size down significantly.
