1. An electronic device, comprising:
a substrate having a surface;
functional metallic traces on a first portion of the surface, the functional metallic traces electrically connected to carry current in the electronic device;
first dummy metallic traces on a second portion of the surface, the first dummy metallic traces electrically isolated from the functional metallic traces, wherein the first dummy metallic traces have a first density; and
second dummy metallic traces on a third portion of the surface, the second dummy metallic traces electrically isolated from the functional metallic traces, wherein the second dummy metallic traces have a second density, the second density different than the first density.
