	A via is a galvanized through hole (plated). It is used only in the layout for connecting top and bottom layer of a PCB at a certain point.[[File:pad.jpg\|left\|padding=20px]] It is used for bringing a track and it's signal to the opposite layer. The image shows the construction principle of a galvanized through hole. It arises when a copper pad gets a drilling with a smaller diameter than the copper itself so that a rest of a copper remains. Then it will be galvanized through. We call the remaining copper a "rest ring".		A via is a galvanized through hole (plated).

	'''Remark:''' If the drill hole is bigger than the copper around there will remain no copper rest ring. Thus no galvanizing and no contacting will happen. It will come out as a bare hole. So whether a galvanizing through will happen or not is dependant on the existance of a copper rest ring.<br><br><br>		'''Remark:''' If the drill hole is bigger than the copper around there will remain no copper rest ring.
