Multi-layer PCBs
A multilayer PCB will, by definition, have 3 or more conductive copper layers, each separated from the others using either fully cured core material, or partially cured prepreg material. The application of heat and pressure in the bonding press fully cures the prepreg material to create the finished multilayer. PTHs take connections from layer to layer in the same manner as a double-sided PCB.
