Abstract

A method for fabricating a microstrip package to optimize signal trace impedance control is disclosed. The method includes patterning a plurality of signal traces on a multilayer substrate, and patterning a plurality of guard traces on the multilayer substrate, that are interspersed alternately among the signal traces to provide noise shielding between the signal traces. In a further embodiment, the traces are patterned on the substrate with a width that is adjusted at different locations based on the presence the guard traces to enable the package to meet a particular impedance requirement.
