Abstract:
1. In a fabrication system for a ceramic package, a method for reducing coupling noise and controlling impedance discontinuity in ceramic packages, the method comprising: providing at least one reference mesh layer; providing a plurality of signal trace layers, each signal layer having one or more signal lines; wherein the at least one reference mesh layer is adjacent to one or more signal layers of the plurality of signal layers; disposing a plurality of vias through sections of the at least one reference mesh layer with each via of the plurality of vias providing one of a voltage (Vdd) power connection or a ground (Gnd) connection; selectively placing a plurality of via-connected coplanar-type shield (VCS) lines relative to the one or more signal lines, with a first VCS line extended along a first side of a first signal line within the plurality of signal layers and a second VCS line extended along a second opposing side of said first signal line; wherein the plurality of VCS lines extend only between two adjacent signal lines wherein each of the plurality of VCS lines interconnect with and extend past one or more vias of the plurality of vias that is located within a directional path along which the VCS lines extends.
