ABSTRACT:
Disclosed is a printed circuit board and a method of preparing the printed circuit board. The printed circuit board has two types of plated through holes. The first type of plated through holes extend to and through an exterior surface of the printed circuit board for receipt of a pin-in-through-hole module or component pin. The second type of plated through holes are for surface mount technology and terminate below the exterior surface of the printed circuit board. These plated through holes contain a fill composition.
