Abstract: This application provides a stiffener ring and a surface packaging assembly. The stiffener ring is configured to correct warpage of a substrate of the surface packaging assembly. The stiffener ring includes an annular stiffener ring body and an adjustment block that is disposed at a same layer as the stiffener ring body and that is fastened to at least one corner of the stiffener ring body. A coefficient of thermal expansion of the adjustment block is less than a coefficient of thermal expansion of the stiffener ring body. Coordination between the adjustment block and the stiffener ring body alleviates an “M-shape” overpressure phenomenon of a warpage deformation caused by the stiffener ring to the substrate at a high temperature, reduces warpage of the substrate, and improves flatness of the surface packaging assembly.

Abstract: A metal-foam structure is used to shield or reduce harmful electromagnetic waves that are generated by electronic devices. A metal-foam material has regulated pores and is incorporated in an electronic device. The metal foam structure shields, prevents, or reduces harmful electromagnetic waves generated by the electronic device from reaching the human body or interfering with a sensitive electronic component. This metal foam is a relatively lightweight material having regulated microscale pore structure. The pores in the metal foam can also form directionality relative to the direction of incoming electromagnetic waves for more effective reflection or absorption of electromagnetic waves. The metal foam can also be used as both an electromagnetic-shielding and a heat-dissipating component for electronics including popular consumer electronics such as mobile phones, notebooks, and high-power desktop computers.
