Multilayer PCB is a circuit board that has more than two layers.
Unlike Double Side PCB which has only two conductive layers of material, multilayer PCB have at least three layers of conductive materials which are buried in the center of material. Each substrate layer in a multilayer board has a conductive metal on both sides of it. Multilayer board typically appear in more complex devices that require a high number of connections. If the device is on the more complex end of the spectrum, then they will require multilayer boards. As technology has become more advanced, multilayer PCB has become more common.
