Product Description

Double sided printed circuit boards are made with a substrate of non-conductive material, over which a layer of copper is placed
on top and the bottom of it, and in the case of double sided boards, the copper is also layered on the bottom side of the substrate.
The circuits on top and bottom layers are connected by a "bridges" called the guide hole (via), which is also called plated through
hole (PTH), and the hole without connecting function is called NPTH holes because there is no metal in hole.
