Water-based paint coating process after metallization and silver plating of common material antenna

Abstract

The invention discloses a water-based paint coating process after metallization and silver plating of a common material antenna. The water-based paint coating process comprises the following steps that S1, a 5G frequency band standard is set for a terminal client, the frequency band, the antenna layout and the requirements are met by the terminal client, and an antenna line is designed for a product covered under a mainboard; and S2, according to the line mold design in the step S1, the punching and shutting off requirement is met, burrs generated by mold punching are optimized through laser punching, the glue thickness of a punched hole is controlled to be 0.03 mm, and the product with the thickness being 0.1 mm touches the punching burrs; and injection molding is carried out according to the designed content. According to the water-based paint coating process after metallization and silver plating of the common material antenna, the appearance surface of the common material is subjected to chemical plating to generate the metallized antenna, the bottleneck of the LDS raw material is broken through, the chemical plating antenna metallization process is optimized, metalized chemical plating antenna can be completed by using any shape of the common material as reserved size, so that the internal clearance space of a mobile phone can be effectively improved, and the radio frequency signal of the mobile phone can be improved; and the silver plating mode meets the nickel-containing standard, and the surface flatness of the chemical silver plating layer is high.

Description

technical field [0001] The invention relates to the technical field of radio frequency antenna manufacturing for mobile phones, in particular to a water-based paint coating process after metallization and silver plating of common material antennas. Background technique [0002] Since electromagnetic waves are extremely susceptible to interference during propagation, mobile phone terminals need to isolate components such as metals, batteries, motors, shields, and cameras when designing antennas, and reserve clearance for the antenna to ensure mobile phone signals. Among them, the metal shell, decoration, and conductive spraying should be more than 20mm away from the antenna, and the distance between the battery (including the electrical connector) and the antenna should be more than 5mm. [0003] The ordinary antenna in the prior art, in the process of painting and processing, the raw materials are relatively restrictive, and the paint is easy to affect the signal strength of...

Problems solved by technology

[0003] The ordinary antenna in the prior art, in the process of painting and processing, the raw materials are relatively restrictive, and the paint is easy to affect the signal strength of the antenna; at the same time, the flatness of the antenna surface is poor, so a common material antenna is designed Water-based paint coating process is necessary after metallized silver plating
