Abstract:
A printed circuit board (PCB) assembly is provided that includes a PCB, an integrated circuit package, an electromagnetic interference (EMI) shield ring, and a heat sink lid. A first surface of the package is mounted to a first surface of the PCB. The EMI shield ring is mounted to the first surface of the PCB in a ring around the package. A first surface of the heat sink lid includes a recessed region and first and second supporting portions separated by the recessed region. The heat sink lid is mated with the EMI shield ring such that the package is positioned in an enclosure formed by the EMI shield ring and the recessed region of the heat sink lid. A second surface of the package may interface with a surface of the recessed region.
