Mobile terminal, antenna assembly of mobile terminal and manufacturing method thereof

Abstract

The invention relates to a mobile terminal, an antenna assembly of the mobile terminal and a manufacturing method thereof. The antenna assembly of the mobile terminal comprises a metal shell and an antenna bonding pad, the metal shell is further used as an antenna, and the antenna bonding pad and the metal shell form a whole through a 3D printing process. The technical scheme provided by the invention has the following advantages: firstly, surface contact between the antenna bonding pad and the metal shell is realized, and the surface contact is firmer and more reliable than a point contact mode in the prior art; secondly, a liquid metal alloy material is sprayed through the 3D printing process, the antenna bonding pad is directly printed on the metal shell, and compared with a spot welding process in the prior art, the operation is convenient, and manpower is saved; and thirdly, the metal alloy material replaces gold in the prior art, so that the material cost is saved.

Description

technical field [0001] The present disclosure relates to the technical field of electronic equipment, and in particular to a mobile terminal, an antenna assembly of the mobile terminal and a manufacturing method thereof. Background technique [0002] The mobile terminal has an antenna assembly for sending and receiving signals. The antenna assembly generally includes an antenna and an antenna pad (also referred to as an antenna PAD). The antenna pad serves as a medium to connect the main board and the antenna. [0003] The following takes a mobile phone as an example to illustrate the technical solution of the antenna assembly of the existing mobile terminal. [0004] Such as figure 1 and figure 2 As shown, the metal battery case 100 of the mobile phone can function as an antenna. The metal battery case 100 (such as an aluminum alloy battery case) is welded with gold foil inside, and the gold foil serves as the antenna pad 200 . The gold foil is formed into a sheet struc...

AI Technical Summary

Problems solved by technology

[0006] First, the gold foil and the battery case are connected by spot welding, and the connection method of point contact is unstable, which may easily lead to the separation of the battery case and the gold foil, resulting in poor contact between the gold foil and the battery case;

[0007] Second, manufacturing the antenna assembly requires at least the following steps: placing the gold foil in place; and welding the gold foil and the battery case, which is a cumbersome process and inefficient;

[0008] Third, the cost of gold leaf is high
