Problems solved by technology

[0003] However, during use, dirt, oil stains, acid and alkali impurities, etc. penetrate into the joint between the plastic and the metal, which will lead to poor bonding between the plastic and the metal
Furthermore, there is a large difference in color and gloss between the plastic part and the metal part of the electronic device prepared by the above method, which affects the appearance of the electronic device

Abstract

A housing, suitable for an electronic device with an antenna, the housing includes a base body, the base body is provided with a slot corresponding to the antenna, a non-conductive film is formed on the surface of the base body surrounding the slot, and the non-conductive film is physically connected And the housings on both sides are electrically isolated. The invention also provides an electronic device using the casing and a manufacturing method of the casing. In the case of the electronic device provided by the present invention, at least one groove is opened on the substrate, and a non-conductive film is formed on the surface surrounding the groove, and the non-conductive film is physically connected and electrically isolated from the substrates on both sides thereof, so that , the signal of the antenna corresponding to the slot can pass through smoothly. At the same time, the non-conductive film and the base have similar appearances, and there will be no large color difference between the base and the non-conductive film. In this way, the housing can achieve Better appearance effect.

Description

technical field [0001] The invention relates to a casing, an electronic device using the casing and a manufacturing method of the casing. Background technique [0002] Due to the advantages of metal shells in terms of appearance, structural strength, heat dissipation effect, etc., more and more manufacturers design electronic devices with metal shells to meet the needs of consumers. However, the metal casing easily interferes with the reception and transmission of signals by the antenna disposed therein, resulting in poor performance of the antenna. To solve this problem, designers often cut the part of the metal shell close to the antenna into small pieces, and then connect the metal pieces by injecting plastic between the metal pieces. The antenna signal can be transmitted from the plastic between the metal pieces. Pass through, so that the electronic device has better radiation efficiency. [0003] However, in the process of use, after dirt, oil stains, acid-base impuri...
