A PTH is a drilled hole whose barrel is intentionally coated with a conductive layer of copper. The plating electrically connects the pad(s) on the top layer to pad(s) on the bottom layer and to any internal copper layers.NPTHs are mechanical holes without copper plating in the barrel. No electrical connection exists between layers.
