    摘要: A carrier for an electronic device such as an integrated circuit chip is designed by assigning two different voltage domains to two separate areas of the contact surface of the carrier, while providing a common electrical ground for both voltage domains. The integrated circuit chip may be a microprocessor having a nominal operating voltage, and the different voltages of the two voltage domains are both within the tolerance range of the nominal operating voltage but one of the voltage domains is aligned with a high power density area of the microprocessor (e.g., the microprocessor core) and provides a slightly greater voltage. The higher power voltage domain preferably has a ratio of voltage pins to ground pins that is greater than one.

    摘要: An integrated circuit substrate is designed and fabricated with a selectively applied transmission line reference plane metal layer to achieve signal path shielding and isolation, while avoiding drops in impedance due to capacitance between large diameter vias and the transmission line reference plane metal layer. The transmission line reference plane defines voids above (or below) the signal-bearing plated-through holes (PTHs) that pass through a rigid substrate core, so that the signals are not degraded by an impedance mismatch that would otherwise be caused by shunt capacitance from the top (or bottom) of the signal-bearing PTHs to the transmission line reference plane. For voltage-plane bearing PTHs, no voids are introduced, so that signal path conductors can be routed above or adjacent to the voltage-plane bearing PTHs, with the transmission line reference plane preventing shunt capacitance between the signal path conductors and the PTHs.

    摘要: Manufacturing circuits with reference plane voids over vias with a strip segment interconnect permits routing critical signal paths over vias, while increasing via insertion capacitance only slightly. The transmission line reference plane defines voids above (or below) signal-bearing plated-through holes (PTHs) that pass through a rigid substrate core, so that the signals are not degraded by an impedance mismatch that would otherwise be caused by shunt capacitance from the top (or bottom) of the signal-bearing PTHs to the transmission line reference plane. In order to provide increased routing density, signal paths are routed over the voids, but disruption of the signal paths by the voids is prevented by including a conductive strip through the voids that reduces the coupling to the signal-bearing PTHs and maintains the impedance of the signal path conductor.

    摘要: A method reduces coupling noise and controls impedance discontinuity in ceramic packages by: providing at least one reference mesh layer; providing a plurality of signal trace layers, with each signal layer having one or more signal lines and the reference mesh layer being adjacent to one or more of the signal layers; disposing a plurality of vias through the at least one reference mesh layer, with each via providing a voltage (Vdd) power connection or a ground (Gnd) connection; selectively placing via-connected coplanar-type shield (VCS) lines relative to the signal lines, with a first VCS line extended along a first side of a first signal line and a second VCS line extended along a second, opposing side of said first signal line. Each of the VCS lines interconnect with and extend past one or more vias located within a directional path along which the VCS lines extends.
