Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with specific embodiments.

[0021] The integrated manufacturing method of mobile terminal equipment casing and antenna disclosed by the present invention is to combine the traditional two-color injection molding process with LDS technology, and use the way of secondary injection to ensure the structural strength of the casing (antenna bracket) and to ensure the structural strength of the casing (antenna bracket). The steps of antenna installation and fixing, and the resulting assembly and performance consistency problems are omitted.

[0022] The invention includes two parts: the manufacturing step of the casing and the manufacturing step of the antenna.

[0023] Among them, the production steps of the casing are as follows: (1) Using a double-material injection molding machine, inject PC or a mixture of PC and glass fiber or a mixture of PC and ABS into the first plastic inlet, and open the...

Abstract

The invention relates to a mobile terminal case and antenna integrated manufacture method which comprises a case manufacture step and an antenna manufacture step. The case manufacture step includes that a dual-material injection molding machine is used, a case plastic material is injected from a first glue inlet, a mold is opened and ejection is not performed after molding, and the mold is closed after the mold is rotated 180 degrees; and then second injection is performed, resins special for laser direct structuring (LDS) are injected and adhered to the case material, the mold is opened, and ejection is performed to manufacture the complete case. The antenna manufacture step includes that by means of laser energy of a laser machine, metal ions in an antenna area are activated and electroplated to form a circuit structure, and finally a protective film is covered. Compared with traditional LDS antenna manufacture methods, the mobile terminal case and antenna integrated manufacture method has the advantages that areas except an antenna area on the case are made of materials which meet case manufacture intensity, installation and connection levels are reduced, installation procedures are simplified, and defects that case installation procedures are large in labor intensity and low in production efficiency in later periods of normal LDS antenna projects are overcome.

Description

technical field [0001] The invention relates to the field of antenna manufacture. Background technique [0002] Mobile communication terminal products such as mobile phones, notebooks, etc., all need radio frequency antennas to transmit and receive electromagnetic wave signals. As the size of these communication terminals continues to shrink and the cost pressure continues to increase, radio frequency antennas require good radiation performance and greater The use of space volume and low production and material costs put forward higher requirements for manufacturers of radio frequency antennas. [0003] Laser Direct Structuring (LDS) technology is a patented technology developed by LPKF, which provides high flexibility for the production of mobile terminal antennas such as mobile phones, and provides great flexibility for three-dimensional design of products. LDS technology uses a laser to irradiate and shape antenna circuits on the surface of complex three-dimensional part...
