Surface metallization process of 5G antenna oscillator

Abstract

The invention discloses a surface metallization process of a 5G antenna oscillator. The surface metallization process comprises the following steps that (1) an oscillator body with a preset structureis manufactured through injection molding; (2) laser carving treatment is carried out on an electroplating area on the surface of the oscillator body, the area, needing to be metalized, of the surfaceof the oscillator body is deeply activated through laser carving, and electroplating can be achieved; (3) the surface of the oscillator body subjected to laser carving is ultrasonically cleaned; (4)the electroplating area of the surface of the oscillator body is subjected to copper electroplating treatment, and a copper plated layer is formed on the electroplating area of the surface of the oscillator body; (5) the oscillator body is subjected to mist tin electroplating treatment, and a tin plated layer is formed on the surface of the copper plated layer; and (6) the oscillator body is subjected to tin protection treatment, and a tin protection agent is sprayed onto the tin plated layer. In the surface metallization process, the procedures of nickel chemical plating and nickel deplatingare omitted, the procedure of surface metallization of the antenna oscillator is simplified, the time taken by the metallization process is reduced, production efficiency is improved, material waste is avoided, and the production cost of enterprises is reduced.

Description

technical field [0001] The invention relates to the field of mobile phone antenna preparation, in particular to a surface metallization process of a 5G antenna vibrator. Background technique [0002] In recent years, with the continuous development of the 4G / 5G wireless communication industry and network upgrades, the frequency of wireless communication is getting higher and higher, and the demand is increasing. The structural design, material selection, manufacturing method and assembly process of the antenna are the guarantee of the reliability, stability and durability of the antenna performance. The antenna vibrator is the most important functional component inside the antenna, and its general structural design is relatively complicated. The traditional antenna vibrator manufacturing process is die-casting of metal materials (aluminum alloy or zinc alloy), or a combination of sheet metal parts, plastic fixing parts and circuits. [0003] At present, the plastic vibrato...

Problems solved by technology

[0003] At present, the plastic vibrator in the antenna industry has introduced the mass-produced LDS process. The main processes include: injection molding, mechanical roughening, ultrasonic cleaning, integral nickel plating on the surface of the antenna vibrator body, and laser engraved dividing lines to separate the surface of the antenna vibrator body from each other. Insulated metallized areas and non-metallized areas, copper plating on metallized areas, nickel stripping on non-metallized areas, etc. However, the existing LDS process has the following disadvantages: copper plating can only be performed after electroless nickel plating, and plating After copper, the nickel plating layer on the non-electroplated area must be removed. The process is complex, time-consuming, and inefficient. It is not convenient for product quality control, not conducive to mass production of antenna vibrators, and requires more materials, resulting in material waste. , leading to high production costs
