A Buried Via hole connects layers inside a multi-layer PCB. These vias cannot be seen on the surface of a Printed Circuit Board. Buried vias are difficult to construct, as they need to be created in layers within the PCB. Designers like to use these vias, as they do not take up board space on every layer, thereby enabling smaller PCBs.

High-density PCBs usually use buried vias.
