Problems solved by technology

[0003] The structure of the traditional shielding box is a container structure, including the upper cover and the lower frame. Although the lower frame in contact with the printed circuit board can already be used as a Surface Mounted Device (SMD), the lower frame is often due to The material is too soft, the structure is too slender, and it is easy to deform or twist during transportation
Even if the degree of deformation or distortion is slight, the SMD production line is still prone to problems such as poor tin intake and drift, and in severe cases, it will even cause a decline in the product qualification rate
In addition, the upper cover part still has to be covered manually by the assembly line, resulting in longer product assembly time

Abstract

The invention discloses an electronic device and a method for manufacturing the same. The electronic device comprises a substrate, a first element, a second element and a barrier shield. The first element and the second element are both arranged on the substrate. The barrier shield is independently arranged between the first element and the second element for inhibiting the electromagnetic interference that the second element has on the first element.

Description

technical field [0001] The present invention relates to an electronic device, and in particular to an electronic device with a shielding wall. Background technique [0002] In recent years, due to the advancement of various communication technologies, manufacturers generally pay attention to the problem of Electromagnetic Interference (EMI) when developing and manufacturing electronic devices. To put it simply, chips, radio frequency components, or metal lines placed on a printed circuit board may be affected by electromagnetic interference from other electronic components placed on the same circuit board, resulting in problems with the overall circuit operation. The traditional method for preventing electromagnetic interference is usually to set a shielding box to cover the chips, radio frequency components, or metal lines to be protected, so as to completely block electromagnetic interference from all directions. [0003] The structure of the traditional shielding box is ...
