An Antenna Preparation Method Alternative to Laser Direct Structuring Technology

Abstract

The invention discloses an antenna preparation method which replaces the laser direct forming technology. The matrix sample enters the preparation room through a conveyor belt, and a drying system is installed in the preparation room to ensure the cleanness and drying of the sample; the matrix sample enters the pre-extraction room through the conveyor belt after drying; After the gas is completed, it enters the buffer chamber through the conveyor belt, and the buffer chamber is subjected to high vacuum pumping by a molecular pump; finally enters the processing chamber, where high-energy ion implantation and low-energy ion beam deposition operations are performed, and finally samples are collected to complete the processing process. The invention provides an antenna preparation method that replaces the laser direct forming technology. The method is based on high-energy ion beam technology, low-energy ion beam technology and related mask technology to form a metal antenna with certain functions. The antenna prepared by the method has the characteristics of low cost, no need for laser powder, good corrosion resistance, high bonding strength, good film consistency, low surface roughness, and environmental protection.

Description

technical field [0001] The invention relates to the technical field of antenna preparation, and more specifically relates to an antenna preparation method that replaces laser direct forming technology. Background technique [0002] As people pay more and more attention to the appearance of smart phones, all mobile phone manufacturers are constantly innovating in the appearance of mobile phones. Mobile phones are becoming thinner and thinner, and more and more metals are used, which brings great challenges to the debugging of mobile phone antennas. Since the current smartphones use more than 5 frequency bands, the difficulty of antenna design is even greater. The commonly used antenna implementation technology is the LDS antenna. The LDS antenna is formed on the formed plastic bracket, and the metal antenna pattern is formed directly on the bracket by using laser laser technology. There are three key factors for the realization of LDS technology. First, LDS special material...

AI Technical Summary

Problems solved by technology

The current LDS antenna technology has three major shortcomings: first, it needs to coat or dope laser powder on the surface of the polymer, and metal nuclei can be formed during the laser scanning process, and the technology of doping laser powder is relatively difficult; second, the formed The surface roughness of the line is too large, which seriously affects the transmission of the signal and increases the loss; the third is that after the metal core is formed, it needs to be thickened by electroless plating, which is poor in environmental protection
