Field of the Invention The present invention relates to an electronic device housing and a method of fabricating the same, and more particularly to an electronic device housing having a three-dimensional antenna and a method of fabricating the same. [Prior Art] Antennas are important components in electronic devices (such as mobile phones, computers, PDAs, etc.). The setting and quality of the antenna directly determine the communication performance of the electronic device. Among the conventional methods for fabricating an antenna for an electronic device, there is a laser direct structuring (LDS) technology. LDS technology refers to the use of laser to form an antenna or conductive pattern on the surface of a substrate. It generally consists of three steps: plastic molding, that is, using laser-activated modified plastic as raw material 201112911 to make plastic parts; laser activation, using focused lightning The projection of the beam onto the plastic part requires the fabrication of an antenna or a conductive pattern to cause a physical chemical reaction of the plastic material to precipitate a metal crystal nucleus on the surface of the plastic part; metallization, even if a portion projected by the laser is deposited with a conductive metal layer . Compared with flexible circuit board antennas and metal plate antennas, LDS antennas can be made into any shape that they actually need, with full three-dimensional functions; and because of laser forming, changing antennas or circuit patterns can be achieved without changing the mold, technical efficiency Extremely high and short product production cycle. • However, the preparation of LDS antennas requires the use of relatively expensive modified plastics, resulting in high product costs and impediment to their use.

A manufacturing method of an electronic device housing, comprising the steps of: providing a molding die having a primary molding cavity and a secondary molding cavity communicating with the primary molding cavity; 201112911 Injection molding plastic in a molding cavity to form a primary molded body of the electronic device casing; molding the plastic containing the laser activator into the secondary molding cavity to form a secondary molded body of the electronic device casing, the secondary molded body Bonding to the primary molded body; laser activating a preselected surface of the secondary molded body; metallizing the preselected surface of the activated secondary molded body to form a three-dimensional antenna. • Compared with the prior art, the manufacturing method of the electronic device casing of the present invention is divided into two injection molding shells, and the primary molding body can use ordinary plastic materials, so that the laser activating material of the secondary molding body can be greatly reduced. The amount of use, which reduces the cost of the product.
