Plated Through Hole
A Plated Through Hole (PTH) is a hole in a PCB that is coated with a conductive material, typically copper, to allow electrical connection between different layers of the board. The process of creating PTHs involves drilling holes in the PCB and then plating the interior walls of the holes with a conductive material to form an electrical connection.
PTHs provide reliable interconnections between layers of a multilayer PCBA and they are also used for mounting through-hole components, such as resistors, capacitors, and integrated circuits, by inserting their leads through the holes and soldering them on the opposite side.
