Embodiment Construction

[0013] The process steps of the antenna manufacturing method of the present invention are as follows:

[0014] (1) Design the mold of the product according to the figure of the antenna, and inject the plastic blank;

[0015] (2) Design and make the jig according to the figure of the antenna, and then install the jig on the blank;

[0016] (3) Vacuum coating, put the cleaned blanks into the vacuum chamber, turn on the mechanical pump to pump to 500Pa, then turn on the Roots pump to pump to 3 Pa, close the bottom valve, open the high valve, use a molecular pump and The trap is pumped to a background vacuum of 5.0E-3Pa; adjust the grating to 0 degrees, add 1700sccm argon, keep the vacuum at 1.5Pa, turn on the turntable, turn on the bias power supply, adjust the parameters to 350V, and continue glow discharge for 4 minutes. Perform ion bombardment to activate the surface; after glow discharge, close the gas circuit, turn off the power, adjust the grating 90 degrees, and pump to 5.0E-3Pa...

Abstract

The invention provides a manufacturing method for an antenna. A plurality of built-in antennas having laminated structures are arranged on an antenna pedestal surface or a mobile phone housing back surface, wherein the surfaces are in an injection-molded state; the laminated structure comprises the following parts from inside to outside: a vacuum coating layer as a first layer; a chemical copper coating layer as a second layer; a chemical nickel coating layer as a third layer; and a chemical gold coating layer as a fourth layer. Beneficial effects of the method are as follows: the antenna hasantioxidation and anticorrosion performances; chemical performances are stable; the antenna surface is fine and smooth and has metal luster; besides, the antenna surface does not discolor and shed; and the antenna highly stands wear and tear. Moreover, the manufacturing cost is low and the yield is high; and therefore, the antenna provided in the invention is suitable for mass production.

Description

Technical field [0001] The invention relates to a method for manufacturing an antenna. Background technique [0002] Existing mobile phone antennas use three-dimensional printing or three-dimensional lasers on plastic blanks. Due to the high process difficulty, slow production speed, and low yield, mass production is difficult and the production cost is high. Summary of the invention [0003] The purpose of the present invention is to provide a method for manufacturing an antenna, which has simple process, low manufacturing cost, and high yield, and is suitable for mass production. [0004] In the antenna manufacturing method of the present invention, a number of built-in antennas with a layered structure are arranged on the surface of the injection-molded antenna base or the back surface of the mobile phone shell. The layered structure is from the inside to the outside, and the first layer is a vacuum coating layer. The second layer is an electroless copper plating layer, ...
