Systems and methods of providing a bare circuit integrated circuit package with a containment ring are described. The bare circuit integrated circuit package may be provided with a substrate connected to a printed circuit board. An integrated circuit may be connected to the substrate. A stiffener ring that surrounds the integrated circuit may be attached to the substrate. A heat sink may be positioned on the stiffener ring and over the integrated circuit such that there is a space between a top of the integrated circuit and a bottom surface of the heat sink. A thermal interface material may be provided to thermally connect the integrated circuit and the heat sink. A containment ring may be positioned between the stiffener ring and the integrated circuit, the containment ring sized and positioned to prevent pumping and/or displacement of the thermal interface material.
