A method for realizing electroless plating antenna with a plastic shell embedded with metal

Abstract

The invention discloses a method for realizing an electroless plating antenna with a plastic case embedded with metal. The method includes: performing electrophoretic coating on the metal part for the first time; designing a mold according to the required structural appearance; The metal part and the plastic shell are subjected to in-mold injection molding, so that the metal part is embedded in the plastic shell to form a metal-embedded plastic shell; an antenna pattern for depositing metal is formed on the plastic shell; the metal-embedded plastic shell placed in an electroless plating solution containing metal ions, so that the metal ions are reduced and deposited on the antenna pattern. Compared with the prior art, the present invention can realize the chemical plating antenna on the plastic shell with embedded metal, thereby improving the strength or decoration of the plastic shell, enhancing the user experience, and using electrophoretic coating technology to have environmental safety. It is economical and practical to improve the yield rate of in-mold injection molding.

Description

Technical field [0001] The present invention relates to the technical field of antenna manufacturing, in particular to a method for electroless plating an antenna with a plastic shell embedded with metal. Background technique [0002] Laser Direct Structuring (LDS) is a 3D-MID (three-dimensional molded interconnection device or electronic component) production technology of professional laser processing and electroless plating (or chemical plating for short). It has the advantages of making ordinary plastics The electrical interconnection of components / circuit boards, the support and protection of components and plastic shells, and the combination of mechanical entities and conductive patterns to form antennas. It has been widely used in antenna circuits on plastic shells. Make. [0003] The manufacturing process of laser direct structuring technology is to first use thermoplastic materials to inject a shell; secondly, irradiate the surface of the shell with a laser to form an ant...

Problems solved by technology

[0005] Since the chemical plating process needs to soak the plastic shell in a strong alkaline solution and a strong acidic solution to achieve the effect of electroless plating on the metal film of the antenna, the current laser direct forming technology chemical plating antenna is used on the plastic shell , and for the plastic shell embedded with metal parts, the metal parts will be corroded during the electroless plating process, and the role of the metal parts cannot be achieved.
