Problems solved by technology

However, the metal shielding frame 101 increases the overall height of the plastic package module, and the plastic sealant can only penetrate into the metal shield frame 101 through the through hole 102 on the metal shield frame 101, and the fluidity of the plastic sealant is poor.
Therefore, the effect of shielding electronic components through metal shielding frames is not good

Abstract

Provided are an electronic device and a manufacturing method thereof. An electronic device comprises a base plate (201), with a ground layer provided in the base plate (201); a first electronic element (202) and a second electronic element (203) provided on the base plate (201); a metallic shield wall (204) provided between the first electronic element (202) and the second electronic element (203); a plastic packaging glue (205) covering the first electronic element (202), the second electronic element (203) and the metallic shield wall (204), wherein there is an opening on the plastic packaging glue (205) and only the metallic face on the top of the shield wall (204) is exposed from the opening; and a conductive thin film (206) covering the metallic face on the top of the shield wall (204) and the plastic packaging glue (205), and being electrically connected to the ground layer of the base plate (201). The electronic device and the manufacturing method thereof can provide a better effect for shielding electromagnetic interference and save packaging costs for shielding an electronic device from electromagnetic interference.

Description

technical field [0001] Embodiments of the present invention relate to electromagnetic interference shielding technologies, and in particular to an electronic device and a method for manufacturing the electronic device. Background technique [0002] The electromagnetic interference shielding design can reduce the external radiation interference of electronic components, and can also reduce the interference of external radiation on electronic components. Many electronic components require electromagnetic interference shielding design. For example, in IC design, it is necessary to separate the radio frequency electronic components from the surrounding electronic components. [0003] In the prior art, a commonly used shielding method for electronic components is mainly to realize the shielding of electronic components through a metal shielding frame. [0004] figure 1 It is a schematic structural diagram of a metal shielding frame in the prior art, such as figure 1 As shown, ...
