Multilayer
Multilayer PCBs are the PCB types that have 3 or more layers. They are preferred when the design demands can not be fulfilled by double-sided PCBs. Devices with more computing power such as PC mainboards, cell phones, telecommunication devices, etc., require multilayer PCB designs that allow running complex ICs and processors.
