Multi-layer PCBs further increase the complexity and density of PCB designs by adding additional layers beyond the top and bottom layers seen in a double-sided configuration. They can be regarded as expansion of double-layer PCBs. With the availability of over thirty layers in multilayer PCBs configurations, multi-layer PCBs allow designers to produce very dense and highly complex designs. Quite often the extra layers in these designs are used as power planes, which supply the circuit with power also reduce the electromagnetic interference levels emitted by designs. Lower EMI levels are achieved by placing signal levels in between power planes. It’s also of note that increasing the number of power planes in a PCB design with increase the level of thermal dissipation a PCB can provide, which is important in high power designs. Similar to double-layer PCBs, components on multi-layer PCBs are interconnected with each other through holes or vias as well.
