CIRCUIT BOARD ASSEMBLY AND ELECTRONIC DEVICES

Abstract

The invention relates to a shielding enclosure, circuit board assembly, and electronic device, wherein the enclosure comprises a housing, a casing, and a circuit board surrounding the shielded area, and at least part of the elements on the circuit board are enclosed within the enclosure. The elements within the housing comprise a first element, wherein the first element has a stepped surface facing the housing. A reinforcement is provided in the area on the housing corresponding to the stepped surface of the first element, wherein at least part of the structure of the reinforcement is located in the area on the housing directly opposite the stepped surface, so that the space formed above the stepped surface of the first element can be utilized. The reinforcement is added to increase the strength of the housing, prevent the area on the housing around the location corresponding to the stepped surface from collapsing, and improve the stability and reliability of the enclosure. In addition...The gap between the first and second molecules remains unchanged or increases only slightly, so a densely packed layout is maintained on the circuit board, saving space for the first four components of the circuit board, and improving the utilization of circuit board space.
