PCB knowledge: Layer Stackup

The purpose of stackup is to interleave the thin laminates and the prepreg sheets in correct sequence and ensure correct layer-to-layer registration. The stackup of multilayer boards can be done in many different ways.

Among multilayer PCB's, 12- layer is the largest number of layers that can be produced easily in 1.6mm thick.
