Description:
PRIORITY 
     This application claims priority under 35 §119(a) to Korean Patent Application Serial No. 10-2015-0015402, which was filed in the Korean Intellectual Property Office on Jan. 30, 2015, the entire content of which is incorporated herein by reference. 
     BACKGROUND 
     1. Field of the Disclosure 
     The present disclosure generally relates to an electronic device, and more particularly, to a housing, a method of manufacturing the housing, and an electronic device including the housing. 
     2. Description of the Related Art 
     Recently, with the development of electronic communication technologies, electronic devices having various functions have appeared on the market. These electronic devices generally have a convergence function for complexly performing one or more functions. 
     In recent years, as the functional gaps between the manufacturers have been significantly reduced, considerable effort has been made to increase the strength of electronic devices, which are becoming gradually slimmer to satisfy consumer demand and to reinforce design aspects of the electronic devices. Such efforts have led to the manufacturing of electronic devices with at least a portion of the electronic device being realized in a metal material to make the electronic device luxurious and appealing. Additionally, the use of a metal material in the electronic device, also serves to solve other problems, such as vulnerability in the strength of the device, grounding problems (for example, preventing a user of the electronic device from receiving an electric shock), and antenna radiation performance reduction problems. 
     Conventionally, housings for such electronic devices, are manufactured by coupling two members of dissimilar materials, and then laminating, on the border surface of the coupled part of the two members, multiple primer layers of different colors to overcome a sense of difference of the border surface of the coupled part, and to minimize a transmissivity difference between the dissimilar materials of the coupled parts. However, with the conventional method, it is difficult to implement an appealing painting surface, and as a result, the value of the design of the electronic device is lowered due to clustering of the primer layers and a resulting low glossiness; and manufacturing process costs also increase. 
     SUMMARY 
     The present disclosure has been made to address at least the problems and disadvantages described above, and to provide at least the advantages described below. 
     Accordingly, an aspect of the present disclosure is to provide a housing for an electronic device that can prevent degradation of design by applying a single primer layer. 
     Accordingly, another aspect of the present disclosure is to provide a housing for an electronic device that contributes to an appealing external appearance by minimizing a difference between transmissivities of a border surface due to coupling of two members of dissimilar materials. 
     Accordingly, another aspect of the present disclosure is to provide a housing for an electronic device that contributes to the slimness of the device by excluding a plurality of primer layers. 
     In accordance with an aspect of the present disclosure, there is provided a method of manufacturing a housing of an electronic device. The method includes forming a basic material of the housing by coupling members of the housing composed of dissimilar materials, planarizing a coupling surface of the basic material of the housing, forming at least one deposition film on the planarized surface, and forming a painting film on the at least one deposition film. 
     In accordance with another aspect of the present disclosure, there is provided a housing of an electronic device. The housing includes a basic material formed by coupling members of the housing composed of dissimilar materials, wherein a coupling surface of the basic material of the housing is planarized, at least one deposition film formed on the planarized surface, and a painting film on the at least one deposition film. 
     In accordance with another aspect of the present disclosure, there is provided an electronic device. The electronic device includes a housing forming at least a portion of an external surface of the electronic device, wherein the housing includes a first member, a second member coupled to the first member to form a basic material of the housing, a primer layer laminated on the basic material of the housing, at least one deposition film laminated on the primer layer, and a painting film laminated on the at least one deposition film.

     Hereinafter, various embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that there is no intent to limit the present disclosure to the particular forms disclosed herein; rather, the present disclosure should be construed to cover various modifications, equivalents, and/or alternatives of embodiments of the present disclosure. In describing the drawings, similar reference numerals may be used to designate similar constituent elements. 
     As used herein, the expressions “have”, “may have”, “include”, or “may include” refer to the existence of a corresponding feature (e.g., numeral, function, operation, or constituent element, such as component), and do not exclude one or more additional features. 
     In the present disclosure, the expressions “A or B”, “at least one of A or/and B”, and “one or more of A or/and B” may include all possible combinations of the items listed. For example, the expressions “A or B”, “at least one of A and B”, and “at least one of A or B” refer to all of (1) including A, (2) including B, or (3) including all of A and B. 
     Expressions, such as “a first”, “a second”, “the first”, or “the second”, used herein may modify various components regardless of the order and/or the importance, but does not limit the corresponding components. For example, a first user device and a second user device indicate different user devices although both of them are user devices.

The memory  130  stores software and/or a program  140 . The program  140  includes, for example, a kernel  141 , a middleware  143 , an Application Programming interface (API)  145 , and/or an application (or an “application program”)  147 . At least one of the kernel  141 , the middleware  143 , and the API  145  may be referred to as an Operating System (OS). 
     The kernel  141  controls or manages system resources (e.g., the bus  110 , the processor  120 , or the memory  130 ) that are used for executing operations or functions implemented in the other programs (e.g., the middleware  143 , the API  145 , or the application programs  147 ). In addition, the kernel  141  may provide an interface that allows the middleware  143 , the API  145 , or the application program  147  to access individual components of the electronic device  101  so as to control or manage the system resources. 
     The middleware  143  plays an intermediary role such that the API  145  or the application programs  147  may communicate with the kernel  141  so as to exchange data. 
     In addition, the middleware  143  processes one or more task requests received from the program  147  according to a priority. For example, the middleware  143  may assign, to at least one of the application programs  147 , a priority for using a system resource of the electronic device  101  (e.g., the bus  110 , the processor  120 , or the memory  130 ). For example, the middleware  143  processes task requests so as to perform scheduling, load balancing, or the like for the task requests, according to the priority assigned to the at least one of the application programs  147 . 
     The API  145  is an interface for allowing the application  147  to control functions provided by the kernel  141  or the middleware  143  and may include at least one interface or function (e.g., commands) for a file control, a window control, an image processing, or a character control. 
     The input/output interface  150  serves as an interface that is capable of delivering commands or data, entered from a user or an external device, such as a first external electronic device  102 , a second external electronic device  104 , or a server  106 , to the other components of the electronic device  101 . Also, the input/output interface  150  outputs commands or data received from the other components of the electronic device  101  to the user or the external device, such as a first external electronic device  102 , a second external electronic device  104 , or a server  106 . 
     The display  160  includes, for example, a Liquid Crystal Display (LCD), a Light Emitting Diode (LED) display, an Organic Light Emitting Diode (OLED) display, or a MicroElectroMechanical systems (MEMS) display, or an electronic paper display. The display  110  displays various contents (e.g., text, image, video, icon, or symbol) to, for example, the user. The display  110  includes a touch screen, and receives a touch input, a gesture input, a proximity input, or a hovering input using, for example, an electronic pen or a part of a user&#39;s body. 
     The communication interface  170  sets communication between the electronic device  101  and the first external electronic device  102 , the second external device  104 , and the server  106 . For example, the communication interface  170  communicates with the second external electronic device  104  and the server  106  by being connected with a network  162  through wired or wireless communication. 
     The wireless communication may use at least one of, for example, LTE (Long-Term evolution), LTE-A (LTE Advance), CDMA (Code Division Multiple Access), WCDMA (Wideband CDMA), UNITS (Universal Mobile Telecommunication System), WiBro (Wireless Broadband), or GSM (Global System for Mobile communication).

     The components may include one or more sensor modules  204 , a camera unit  205 , and an LED indicator  206 . 
     The sensor module  204  includes at least one of, for example, an illumination intensity sensor (for example, a light sensor), a proximity sensor, an infrared ray sensor, and an ultrasonic wave sensor. 
     The LED indicator  206  is for allowing a user of the electronic device  200  to recognize state information of the electronic device  200 . 
     The electronic device  200  includes a metal member  210  (for example, may contribute to at least a portion of the dually injection-molded housing as a metal bezel). The metal member  210  is arranged along a periphery of the electronic device  200 , and extends to the periphery and at least a portion of the rear surface of the electronic device  200 . The metal member  210  defines the thickness of the electronic device  200  along the periphery of the electronic device  200 , and is formed in a loop. However, the present disclosure is not limited thereto, and the metal member  210  may contribute to at least a portion of the thickness of the electronic device  200 . The metal member  210  may be arranged only in at least an area of the periphery of the electronic device  200 . The metal member  210  includes one or more segmental parts  215  and  216 , and the unit metal members, i.e. the lower metal member  214  and the upper metal member  213  separated by the segmental parts  215  and  216  may be utilized as antenna radiation bodies. 
     The metal member  210  has a loop shape along the periphery, and contributes to the entire thickness of the electronic device  200 . When the electronic device  200  is viewed from the front side, the metal member  210  may have a right metal member  211 , a left metal member  212 , an upper metal member  213 , and a lower metal member  214 . Here, the above-described lower metal member  214  and upper metal member  213  may contribute as unit metal members formed by the segmental parts  215  and  216 . 
       FIG. 2B  is a perspective view illustrating a rear surface of an electronic device, according to an embodiment of the present disclosure. 
     Referring to  FIG. 2B , a cover member  220  is arranged on the rear surface of the electronic device  200 . At least a portion of the cover member  220  is integrally formed with the metal member  210  to contribute as a housing of the electronic device  200 . However, the present disclosure is not limited thereto, and the cover member  220  may be a battery cover for protecting a battery pack detachably installed in the electronic device  200  and making the external appearance of the electronic device  200  appealing. A camera unit  217  and a flash  218  are arranged on the rear surface of the electronic device  200 . 
     The housing may extend to at least some portions of the metal member  210  and the cover member  220 . The housing may be formed by coupling the two members having dissimilar materials. The members of dissimilar materials includes the metal member  210 , and the cover member  220  composed of various materials, such as glass, composite materials (GFRP, CFRP), a synthetic resin, and ceramic, which is coupled to the metal member  210 . The metal member  210  and the cover member  220 , composed of dissimilar materials, may form one housing through various methods. For example, the metal member  210  and the cover member  220  may be coupled to each other through various methods such as dual injection-molding, insert injection-molding, and mechanical coupling. 
     Because the housing formed of dissimilar materials has different transmissivities, a visual sense of difference can be removed by forming a deposition film and laminating a painting film on the deposition film. Because a plurality of primer layers for removing the visual sense of difference are excluded by forming a deposition film on the housing formed of dissimilar materials, a manufacturing process becomes simplified and manufacturing costs are reduced. 
       FIG. 3  is a flowchart of a method of manufacturing a housing of an electronic device, according to an embodiment of the present disclosure.  FIG. 4A  is a view illustrating a metal member of a housing of an electronic device, according to an embodiment of the present disclosure.  FIG. 4B  is a view illustrating a state in which a non-metal member and a metal member of a housing of an electronic device are dually injection-molded together, according to an embodiment of the present disclosure.  FIGS. 5A to 5E  are diagrams illustrating a procedure of manufacturing a housing of an electronic device, according to an embodiment of the present disclosure. Referring to  FIGS. 3, 4A to 4B, and 5A to 5E , a process for manufacturing the housing of electronic device  200 , as shown with reference to  FIGS. 4A to 5B , will be described with reference to  FIG. 3 .  FIGS. 5A to 5E  are sectional views taken along line A of  FIG. 4B . 
     Referring to  FIG. 3 , in step  301 , as illustrated in  FIG. 4A , a metal member  410  having a predetermined shape may be manufactured. The metal member  410  may be formed of various materials such as aluminum, magnesium, and Steel Use Stainless (SUS). The metal member  410  may be finished as a desired product through casting or pressing. The metal member  410  includes a left metal member  412 , a right metal member  411 , an upper metal member  413 , and a lower metal member  414  that contribute to the periphery of the electronic device  200 , and one or more of the metal member  410  extends to a cover member area  415 . The metal member  410  includes an opening area  416  into which the non-metal member  420  (shown in  FIG. 4B ) is injection-molded. 
     Thereafter, in step  303 , as illustrated in  FIG. 4B , the metal member  410  and the non-metal member  420  are coupled to each other. The metal member  410  and the non-metal member  420  may be coupled to each other through dual injection-molding or insert injection-molding. 
     Thereafter, in step  305 , as illustrated in  FIGS. 5A and 5B , planarization is performed on a border surface where the metal member  410  and the non-metal member  420  are coupled. The planarization includes buffing for eliminating a step  4201  formed on the border surface of the metal member  410  and the non-metal member  420 . The planarization of the metal member  410  and the non-metal member  420  may be performed on the entire surface as well as on the border surface. 
     Thereafter, in step  307 , as illustrated in  FIG. 5C , a primer layer  510  is formed on the planarized surfaces of the metal member  410  and the non-metal member  420 . The primer layer  510  may be formed of one or more of olefin-based, acryl-based, and urethane-based materials. 
     The primer layer  510  is formed by painting a solvent, such as glass, an acryl-based material, or an SiO2-based material, such as urethane. However, the present disclosure is not limited thereto, and the primer layer  5110  may be formed by a transparent urethane paint. The process of forming the primer layer  510  involves performing a deposition process, which functions to uniformly and smoothly apply and stick a deposition material to the surface of the housing. The housing coated with the primer layer  510  may be cured through a drying process by an oven or through a natural drying process. 
     Thereafter, in step  309 , as illustrated in  FIG. 5D , after the primer layer  510  is cured, a deposition film  520  is applied on the primer layer  510 . According The deposition method includes Physical Vapor Deposition (Ph D) and Chemical Vapor Deposition (CVD). The deposition film  520  is formed of at least one of Ti-based, Sn-based, and Cr-based materials. The deposition film  520  includes at least one of TiO 2 , TiN, TiCN, and SiO 2 . The deposition film  520  is formed by depositing at least one of a silicon oxide (SiO 2 ) film, a titanium oxide (TiO 2 ) film, an aluminum oxide (Al 2 O 3 ) film, a zirconium oxide film, and (ZrO 2 ) tantalum oxide (Ta 2 O 5 ) film. The deposition film  520  is formed by alternately forming two or more materials, for example, SiO 2 —TiO 2 , Al 2 O 3 —TiO 2 , SiO 2 —ZrO 2 , Al 2 O 3 —ZrO 2 , and SiO 2 —Ta 2 O 5 . 
     Thereafter, in step  311 , as illustrated in  FIG. 5E , a second primer layer  531  (for example, a urethane-based material) may be formed and cured on the disposition film  520  for forming a painting film  530  thereon. 
     In step  313 , the painting film  530  is formed on the second primer layer  531  cured in step  311 . The painting film  530  includes a base coating layer and a clear coating layer. 
     Buffing is formed immediately after the metal member  410  and the non-metal member  420 , composed of dissimilar materials, are coupled to each other, but the present disclosure is not limited thereto. After the metal member  410  and the non-metal member  420  are coupled to each other and the primer layer is applied and cured on the coupled members as the concept of putty, buffing may be performed and then a deposition film may be formed on the huffed portion. 
       FIGS. 6A and 6B  are sectional views of a housing of an electronic device, according to an embodiment of the present disclosure. 
     Referring to  FIG. 6A , a first primer layer  510  is formed on the surface where the two members of dissimilar materials, for example, the metal member  410  and the non-metal member  420 , are coupled through dual injection-molding. The first primer layer  510  is formed to have a thickness in a range of 30 μm to 40 μm. The deposition film  520  is formed on the first primer layer  510 . The deposition film  520  may be formed to have a thickness in a range of 100 Å to 700 Å. The deposition film  520  may be formed of a metallic material to minimize reflectivity between the dissimilar materials and conceal the border portion. A second primer layer  531  for forming a painting film  530  is formed on the deposition layer  520 . The painting film  530  includes a base coating layer  532  and a clear coating layer  533  which is formed on the second primer layer  531 . The painting film  530  including the second primary layer  531  may be formed to have a thickness in a range of 30 μm to 40 μm. 
     The painting film  530  includes a basic color painting film coated on the second primer layer  531 . A transparent film may be formed on the basic color painting film. The transparent film may be formed by ejecting a transparent urethane paint to protect the basic color painting film A Soft Feel (SF) paint may be applied on the transparent film to naturally express a color of the basic color paint film. 
     Accordingly, in the present disclosure, because the thickness from the first primer layer  510  which is initially applied to the outer surface of the metal member  410  and the non-metal member  420  to the final painting film  530  may have a range of 70 μm to 80 μm, the thickness of the electronic device may be significantly reduced, as compared to that of the related art where the thickness from a primer layer formed on the upper surface of a housing to the final painting film is an average of 120 μm. Thus, the method of manufacturing the housing of an electronic device, according to the various embodiments of the present disclosure, contributes to an increased slimness of the electronic device and reduces the number of manufacturing processes. 
     Referring to  FIG. 6B , the deposition film  520  has a plurality of layers, such as a first deposition film  521  and a second deposition film  522 . The first deposition film  521  and the second deposition film  522  may be formed of different materials. The deposition film  520  may be deposited by alternately using two or more deposition materials. For example, the deposition film  520  may be formed by alternately depositing a first deposition material that achieves a first desired refractivity by mixing two or more deposition materials, and a second deposition material that achieves a second desired refractivity different from the first refractivity. 
     For example, the refractivity of the silicon oxide (SiO 2 ) film is 1.4, the refractivity of the titanium oxide (TiO 2 ) film is 2.4, and the refractivity of the aluminum oxide (Al 2 O 3 ) film is 1.7. Accordingly, if the silicon oxide (SiO 2 ) film and the titanium oxide (TiO 2 ) film, having a large refractivity difference, are alternately deposited, it is very advantageous for a ceramic pearl texture effect and an anisotropic color reproduction effect. 
       FIG. 7  is a view illustrating a pattern shape of a deposition film formed in a non-metal member of a housing of an electronic device, according to an embodiment of the present disclosure. 
     Referring to  FIG. 7 , illustrates a housing  700  having a metal member  710  and a non-metal member  720  is provided. The upper surface of the housing  700  is huffed and a deposition material is applied on the buffed surface to form a deposition film. 
     Non-metal member  720  is exposed to the upper and lower sides of the metal member  710 . When the housing  700  is applied to a communication electronic device, at least one antenna radiation body may be arranged in an area of the metal member  710  in which the non-metal member  720  is exposed from the metal member  710 . The deposition film may be coated with a metal material to lower radiation performance of the antenna radiation body. Accordingly, the deposition film of the metal member  710  formed in the area of the non-metal member  720  may include a pattern in the form of a mesh. However, the present disclosure is not limited thereto, and the deposition film may include various patterns having regular or irregular repeated periods. A signal of an operation band of the antenna radiation body may be radiated through the non-metal member  720  by the pattern. 
     According to various embodiments of the present disclosure, by coupling the members of dissimilar materials and forming a deposition film on the upper surface of the coupled members, a sense of difference between the dissimilar materials can be minimized and the difference between the transmissivities can be minimized, which can contribute to an appealing design and reduce manufacturing time and manufacturing cost with a relatively small number of processes.
