A kind of preparation method of housing with built-in antenna

Abstract

The invention discloses a preparation method of a casing with a built-in antenna. The casing includes a first injection molding layer and a hardware piece. The first injection molding layer is formed on the outer edge of the hardware piece by injection molding. The first injection molding layer includes an outer The surface and the inner surface, the first injection layer is provided with a communication structure, the outer end surface of the communication structure and the outer surface of the first injection layer around the outer end surface are provided with a first roughening treatment layer. A first conductive layer is provided on the treatment layer, a first conductive layer is formed by metal spraying on the first roughened treatment layer, and a second conductive layer is provided on the outer surface of the first conductive layer and the first injection molding layer around the first conductive layer. The injection layer is provided with a contact structure on the inner end face of the communication structure. The invention has the advantages of ensuring the yield rate, low defective rate, low cost, easy processing and operation, stable structure, resistance to beating and falling, and the like.

Description

technical field [0001] The invention belongs to the technical field of electronic equipment, and in particular relates to a method for preparing a casing with a built-in antenna. Background technique [0002] The antennas of existing electronic devices such as mobile phones are usually installed inside the mobile phone. As the functions of mobile phones increase, there are more and more corresponding electronic components. The utilization rate of the internal space of mobile phones has reached the limit. The number of antennas has increased significantly. In order to meet the requirements of antenna design, it is necessary to place the antennas as far away as possible from the internal metal parts. The interior of the mobile phone will become the mainstream, and the method of preparing the antenna on the casing has appeared on the market. The casing prepared by this method needs to be polished before painting the exterior surface of the casing. In the process of repainting,...

The interior of the mobile phone will become the mainstream, and the method of preparing the antenna on the casing has appeared on the market. The casing prepared by this method needs to be polished before painting the exterior surface of the casing. In the process of repainting, the yield rate cannot be guaranteed, and it is easy to cause increased defects and high costs
