Plated Through Hole (PTH) Design

Plated through-holes (PTH) connect together the top, bottom, and any required internal conductor layers. PTHs are drilled oversize to accommodate the thickness of the copper plating that will cover the entire barrel of the hole as well as the surface of the outer pads. Exterior pads maybe plated along with the entire foil surface or selectively plated just at the PTH side.
