    摘要: A device and/or apparatus having plated through holes (PTHs) which are coated to reduce impedance discontinuity in electronic packages. PTH vias are imbedded in the core of a printed circuit board comprising a core layer, a plurality of buildup layers, a plurality of micro-vias, and a plurality of traces. Traces electrically interconnect each of the micro-vias to PTH vias, forming an electrically conductive path. PTHs are coated with a magnetic metal material, such as nickel, to increase the internal and external conductance of the PTHs, thereby providing decreased impedance discontinuity of the signals in electronic packages.

    摘要: An electrically optimized and structurally protected micro via structure for high speed signals in multilayer interconnection substrates is provided. The via structure eliminates the overlap of a contact with the reference planes to thereby reduce the via capacitance and thus, the via impedance mismatch in the via structure. As a result, the via structure is electrically optimized. The via structure further comprises one or more floating support members placed in close proximity to the via within a via clearance area between the via and the reference planes. The floating support members are “floating” in the sense that they are not in electrical contact with either the via or the reference planes. Thus, they are not provided for purposes of signal propagation but only for structural support. The floating support members may be connected to one another by way of one or more microvia structures.
