Multilayer PCB is a type of circuit board that contains three or more layers of conductive material. These boards increase the available area for wiring. Whenever we talk about a number of layers, it means we are considering a number of conducting patterns on the board. Multilayer PCBs are normally Rigid PCB. It is because it is very difficult to create it in a flexible format.
The number of layers depends on your needs. So layers could be up to 100. However, 4 to 8 layer PCBs have common usage in various applications. Circuitry gets complex when layers increase. So you can customize different numbers of layers according to your needs.
