What are the multi layers on a pcb?
Statement: This post is only the personal view of the author and does not represent the opinions of


Multilayer PCBs consist of three types of layers: 1. the core on which the copper is attached, 2. the prepreg layers which insulate the different copper layers from each other, 3. the copper itself. So the multi layers on a pcb usually refers to the core layer,prepreg and copper layer.


For a multilayer PCB, the additional layers are stacked inside the plastic. The vias cross all the layers or just some of them, like buried vias.
