    Abstract: Embodiments disclosed herein include electronic packages with a ground plate embedded in the solder resist that extends over signal traces. In an embodiment, the electronic package comprises a substrate layer, a trace over the substrate layer, and a first pad over the substrate layer. In an embodiment, a solder resist is disposed over the trace and the first pad. In an embodiment a trench is formed into the solder resist, and the trench extends over the trace. In an embodiment, a conductive plate is disposed in the trench, and is electrically coupled to the first pad by a via that extends from a bottom surface of the trench through the solder resist.
