Abstract:
A circuitized substrate comprising:a substrate having a substantially planar upper surface; a conductive layer positioned on the upper surface including of the substrate, said conductive layer including a bottom surface that is in direct mechanical contact with the upper surface of the substrate, said conductive layer including a top surface above and separated from the upper surface of said substrate, said conductive layer including a first opening extending from the top surface of the conductive layer to the bottom surface of the conductive layer, said conductive layer including a first conductive segment, said first conductive segment having a first end surface and second end surface, said first end surface coinciding with a side wall of the first opening, said side wall being substantially perpendicular to the upper surface of the substrate, said second end surface comprising a first point on the bottom surface of the conductive layer and a second point on the top surface of the conductive layer, said first point being direct mechanical contact with the upper surface of the substrate, wherein a straight line through the first point and the second point forms an acute angle with the upper surface of the substrate.
