Method for realizing chemical plated antenna on plastic housing embedded with metal

Abstract

The invention discloses a method for realizing a chemical plated antenna on a plastic housing embedded with metal. The method comprises: performing first electrophoretic coating of a metal piece; designing a mold according to a required structural appearance; performing intra-mold injection of the metal piece after the first electrophoretic coating and a plastic housing to enable the metal piece to be embedded into the plastic housing to form the plastic housing embedded with metal; forming an antenna pattern for depositing metal on the plastic housing; and putting the plastic housing embedded with metal into a chemical plating liquid containing metal ions to enable the metal ions to be reduced and deposited on the antenna. Compared with the prior art, the method enables the chemical plated antenna to be realized on the plastic housing embedded with metal, so that effects, such as strength or decoration, of the plastic housing are improved, and a user's experience is enhanced. At the same time, the method using electrophoretic coating technology has environmental security, and the yield of qualified products of intra-mold injection is increased, so that the method has economical practicability.

Description

technical field [0001] The invention relates to the technical field of antenna production, in particular to a method for implementing an electroless plating antenna with a metal-embedded plastic case. Background technique [0002] Laser Direct Structuring (LDS) is a 3D-MID (three-dimensional molded interconnect device or electronic component) production technology of professional laser processing and chemical plating (or electroless plating) process, which has the ability to make ordinary plastic Component / circuit board electrical interconnection, support and protection of components and plastic shells, etc. It also has the functions of combining mechanical entities and conductive patterns to form antennas. It has been widely used in the antenna lines on plastic shells. make. [0003] The manufacturing process of laser direct structuring technology is to firstly use thermoplastic materials to injection mold a shell; secondly, the laser is irradiated on the surface of the sh...

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.
