Embodiment 1

[0031] The manufacturing method of the 5G three-dimensional laser engraved mobile phone antenna on the surface of the glass substrate, the process includes: laser, water washing, minhua, water washing, activation, water washing, electroless Cu plating, water washing, electroless Ni plating, drying, and post-plating treatment. The main steps are as follows:

[0032] (1) Laser: After cleaning the smooth surface of the glass substrate, use ND:YVO 4 The ultraviolet laser is used for lasing. During the lasing process, the glass substrate needs to be reversed to etch the wiring and shape of the main communication antenna. The diameter of the laser engraving spot is 0.05mm, forming a radium engraving area with a rough texture on the frosted surface.

[0033] The setting parameters of the laser engraving machine are: wavelength 355nm, light output power 20KHz, pulse width 2us, spot moving speed 100mm / s, scanning line spacing 0.07mm, light output power 3W.

[0034] (2) Washing: Put th...

experiment example 2

[0047] The manufacturing method of the 5G three-dimensional laser engraved mobile phone antenna on the surface of the glass substrate, the process includes: laser, water washing, sensitization + activation, water washing, electroless Cu plating, water washing, electroless Ni plating, water washing, electroless gold plating, drying, post-plating treatment, specifically Proceed as follows:

[0048] Steps (1) and (2) in this embodiment are the same as in Embodiment 1.

[0049] (3) Sensitization + activation: in the collagen palladium acidic solution, the Pd in ​​the collagen palladium activation solution 2+ and Sn 2+ It will react to generate adsorptive colloidal palladium particles, and absorb excess Sn in the solution 2+ , exists in colloidal form. The glass substrate with water film completed in the previous step is immersed in the collagen palladium activation solution. The radium engraved area first absorbs the divalent tin ions in the solution, and then absorbs the chlor...

Abstract

The invention aims to provide a manufacturing method for an inorganic non-metallic material 5G three-dimensional mobile phone antenna through laser engraving. On an inorganic non-metallic surface, a laser machine conducts laser engraving on distribution wiring of the 5G three-dimensional mobile phone antenna, a dense surface metal layer is precipitated in a laser engraving area through sensitization and activation, through chemical plating, the laser engraving area is covered with a chemical plating metal layer, the 5G three-dimensional mobile phone antenna is chemically plated on a substrateafter laser engraving, and thus performance indexes required by 5G for the mobile phone antenna are reached.

Description

technical field [0001] The invention relates to a method for manufacturing a 5G mobile phone antenna, in particular to a method for manufacturing a 5G three-dimensional radium-carved mobile phone antenna made of inorganic non-metallic materials. The activation of the activator solution, combined with the method of electroless metal plating, causes physical and chemical changes in the lasered areas of the inorganic non-metallic surface, thereby changing its properties to achieve the purpose of making electronic wiring on the inorganic non-metallic surface. The conductive circuit can be made on the smooth inorganic non-metallic surface by this method, and this method is applicable to all electronic wiring components of the inorganic non-metallic substrate. Background technique [0002] With the development of communication technology, the number of antennas on terminal equipment is increasing; due to the shielding of antenna signals by metal materials, the design of all-metal ...
