Abstract:
A plurality of coaxial leads is made within a single via in a circuit substrate to enhance the density of vertical interconnection so as to match the demand for higher density multi-layers circuit interconnection between top circuit layer and bottom circuit layer of the substrate. Coaxial leads provide electromagnetic interference shielding among the plurality of coaxial leads in a single via.
