An improvement is presented for connecting conductive components of a built-up circuit board. Rather than using vias or micro vias to connect a conductive layer to a conductive component separated by an insulating layer, an elongated via is used. In one embodiment, the elongated via has a length that is sufficient to directly coupled a first layer to the edge of a via in a lower layer. Thus, it can be said that the elongated via "self-aligns" with the via in the lower layer. In doing so, electrical connections from one side of a circuit board to a component coupled to the other side of the circuit board are more direct leading to a reduction in parasitic induction.
