    Abstract: Embodiments herein disclose techniques for electronic apparatuses including a printed circuit board (PCB) and an electromagnetic interference (EMI) shield for the PCB. An electronic apparatus may include a PCB with a plurality of layers including a ground layer. The PCB may include a cutout through the plurality of layers of the PCB. An EMI shield may be mounted to a bottom side of the PCB along an edge of the cutout, where the EMI shield may be coupled to the ground layer through an ohmic contact. The EMI shield may be flat. Other embodiments may also be described and claimed.

    Abstract: Particular embodiments described herein provide for an electronic device that can be configured to include a substrate, a radiation source on the substrate, a ground on the substrate, where the ground is located around the radiation source, and a heat spreader over the radiation source, where the heat spreader includes one or more ground coupling mechanisms that are in contact with the ground on the substrate. The one or more ground coupling mechanisms in contact with the ground on the substrate create a radiation shield that at least partially keeps radiation from the radiation source from extending past the substrate.

    Abstract: A semiconductor package and a packaged electronic device are described. The semiconductor package has a foundation layer and a planar filtering circuit. The circuit is formed in the foundation layer to provide EMI/RFI mitigation. The circuit has one or more conductive traces that are patterned to form an equivalent circuit of inductors and capacitors. The one or more conductive traces include planar metal shapes, such as meanders, loops, inter-digital fingers, and patterned shapes, to reduce the z-height of the package. The packaged electronic device has a semiconductor die, a foundation layer, a motherboard, a package, and the circuit. The circuit removes undesirable interferences generated from the semiconductor die. The circuit has a z-height that is less than a z-height of solder balls used to attach the foundation layer to the motherboard. A method of forming a planar filtering circuit in a foundation layer is also described.
