Production method of antenna assembly and antenna assembly

Abstract

The invention discloses a production method of an antenna assembly and an antenna assembly. The production method is characterized in that a plurality of grooves are disposed in a surface of a base material, and the surface of the base material is provided with a metal antenna coating, which is used to cover the grooves to form a plurality of tin accommodation grooves; the tin pastes can be disposed in the tin accommodation grooves in a filled manner; a metal elastic sheet is disposed on the metal antenna coating in an adhesive manner by a conductive double-sided adhesive tape; the conductive double-sided adhesive tape is provided with a plurality of first through holes corresponding to the tin accommodation grooves, and the metal elastic sheet is provided with a plurality of second through holes corresponding to the first through holes; the first through holes and the second through holes are aligned with each other in a penetrating manner, and are aligned with the tin accommodation grooves; the single-point heating of the tin pastes in the tin accommodation grooves can be carried out to melt the tin pastes, and then the metal elastic sheet can be conducted with the metal antenna coating to complete the production. The production method is advantageous in that the antenna assembly can be produced in a way of combining the adhesive connection using the conductive double-sided adhesive tape with the single-point welding, and therefore the overflowing of the soldering paste and the flux can be prevented, the consistency of the elastic sheet assembly height can be improved, the good conduction between the antenna coating and the elastic sheet can be realized, and the quality of the tin pastes can be observed directly.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a manufacturing method of an antenna component and an antenna component. Background technique [0002] At present, with the continuous development of electronic products and the advent of the SMART era, wireless networks are used more and more frequently, and the antenna requirements for consumer electronic products such as mobile phones, laptops, PADs, stereos, smart watches, and routers are getting higher and higher. [0003] Such as figure 1 As shown, the assembly method of the antenna assembly 100 of the existing product is that the shrapnel 130 is directly welded on the plastic antenna 110 through the solder paste layer 120. There are many problems in this assembly structure. After the shrapnel 130 is welded to the plastic antenna 110 through the solder paste layer 120 , will cause solder paste overflow, flux overflow, etc., which will affect the appearance of the product;...

AI Technical Summary

Problems solved by technology

[0003] like figure 1 As shown, the assembly method of the antenna assembly 100 of the existing product is that the shrapnel 130 is directly welded on the plastic antenna 110 through the solder paste layer 120. There are many problems in this assembly structure. After the shrapnel 130 is welded to the plastic antenna 110 through the solder paste layer 120 , will cause solder paste overflow, flux overflow, etc., which will affect the appearance of the product; the solder paste layer 120 is located at the bottom of the spring 130 and covered by the spring 130, and its melting condition is not intuitive, the detection is poor, and the assembly quality is difficult to guarantee; after the solder paste layer 120 is melted, The assembly height of the shrapnel 130 will have a height difference due to the coating and flow of solder paste, and the height consistency is poor; in order to melt the solder paste layer 120, the entire bottom area of ​​the shrapnel 130 needs to be heated, which will easily cause the large area of ​​plastic of the plastic antenna 110 to be heated and deformed , affecting product quality
