Problems solved by technology

[0004] In the existing mobile phone radiation protection technology, for example, gaskets containing ferrite or wave absorbers are pasted on the surface of the chip or inside the circuit board and the casing, so that the electromagnetic wave is partially controlled, because the wave absorbing material converts the electromagnetic energy into Heat energy, thus aggravating the difficulty of heat dissipation inside electronic products; and the low thermal conductivity of ferrite, it is not suitable to transfer the converted heat to the outside of the device, which requires a new heat dissipation solution with high thermal conductivity and electromagnetic wave absorption performance

Abstract

Aiming at the problems existing in the present cooling and radiation protection technologies of electronic products, the invention provides an SMD (surface mounted device) with cooling and electromagnetic wave absorption functions, which is applied to electronic equipment. The SMD comprises a decoration layer, a cooling and electromagnetic wave absorption layer for cooling and electromagnetic wave absorption and a mounting layer, wherein the cooling and electromagnetic wave absorption layer is arranged between the decoration layer and the mounting layer. The SMD further comprises a protective stripping layer which is arranged below the mounting layer and used for protecting the adhesiveness of the mounting layer, and the stripping layer is taken off before the SMD is used, and then the SMD is mounted at a position needing cooling and electromagnetic wave absorption. Furthermore, the cooling and electromagnetic wave absorption layer is of a structure consisting of more than two layers, including a cooling layer and an electromagnetic wave absorption layer which are independent from each other; accordingly, the cooling and electromagnetic wave absorption layer can be a single-layer structure and is made of a material with cooling and cooling and electromagnetic wave absorption functions. The invention also provides the preparation and application methods of the SMD. The SMD with cooling and electromagnetic wave absorption functions is applied to a shell of electronic equipment, and the shell of the electronic equipment includes but is not limited to a mobile phone shell, a network card, a panel personal computer shell hot spot, a netbook shell hot spot, notebook computer shell hot spot, game equipment and other consumer mobile equipment can improve cooling effect, reduce temperature and weaken electromagnetic wave radiation.
