To address the above-discussed deficiencies, it is a primary object to provide a case that can provide waterproof, dustproof, and insulation effects by properly arranging an aperture of an electronic device that uses an area of the case as an antenna, and an electronic device including the same.

Those skilled in the art will understand that the principles of the present disclosure may be implemented in any suitably arranged electronic device and corresponding case for the electronic device.

Various embodiments of the present disclosure may be described with reference to accompanying drawings. With regard to description of drawings, similar elements may be marked by similar reference numerals.

In the disclosure disclosed herein, the expressions "have", "may have", "include" and "comprise", or "may include" and "may comprise" used herein indicate existence of corresponding features (e.g., elements such as numeric values, functions, operations, or components) but do not exclude presence of additional features.

In the disclosure disclosed herein, the expressions "A or B", "at least one of A or/and B", or "one or more of A or/and B", and the like used herein may include any and all combinations of one or more of the associated listed items. For example, the term "A or B", "at least one of A and B", or "at least one of A or B" may refer to all of the case (<NUM>) where at least one A is included, the case (<NUM>) where at least one B is included, or the case (<NUM>) where both of at least one A and at least one B are included.

The terms, such as "first", "second", and the like used herein may refer to various elements of various embodiments, but do not limit the elements. Furthermore, such terms may be used to distinguish one element from another element. For example, "a first user device" and "a second user device" may indicate different user devices regardless of the order or priority thereof. For example, "a first user device" and "a second user device" indicate different user devices.

It will be understood that when an element (e.g., a first element) is referred to as being "(operatively or communicatively) coupled with/to" or "connected to" another element (e.g., a second element), it may be directly coupled with/to or connected to the other element or an intervening element (e.g., a third element) may be present. In contrast, when an element (e.g., a first element) is referred to as being "directly coupled with/to" or "directly connected to" another element (e.g., a second element), it should be understood that there are no intervening element (e.g., a third element).

According to the situation, the expression "configured to" used herein may be used as, for example, the expression "suitable for", "having the capacity to", "designed to", "adapted to", "made to", or "capable of". The term "configured to" must not mean only "specifically designed to" in hardware. Instead, the expression "a device configured to" may mean that the device is "capable of" operating together with another device or other components. CPU, for example, a "processor configured to perform A, B, and C" may mean a dedicated processor (e.g., an embedded processor) for performing a corresponding operation or a generic-purpose processor (e.g., a central processing unit (CPU) or an application processor) which may perform corresponding operations by executing one or more software programs which are stored in a memory device.

Terms used in the present disclosure are used to describe specified embodiments and are not intended to limit the scope of the present disclosure. The terms of a singular form may include plural forms unless otherwise specified. Unless otherwise defined herein, all the terms used herein, which include technical or scientific terms, may have the same meaning that is generally understood by a person skilled in the art.

<FIG> is a flow chart that illustrates a method for manufacturing a case according to an embodiment of the present disclosure. <FIG> is a view illustrating a shape of a case in a case manufacturing process according to an embodiment of the present disclosure.

Referring to <FIG>, the method for manufacturing a case, for example, may include a preform preparing operation <NUM>, an adhesive coating operation <NUM>, an insert injection-molding operation <NUM>, a bonding layer washing and removing operation <NUM>, and a final machining and surface-processing operation <NUM>. The bonding layer washing and removing operation <NUM> may be omitted depending on a condition of the manufacturing process. Further, the bonding layer washing and removing operation may be included in the surface-processing operation <NUM>.

The preform preparing operation <NUM>, for example, may be an operation of preparing a preform that will be utilized as a case of an electronic device <NUM>. In the preform preparing operation <NUM>, a preform, at least a portion of which is metallic, may be provided. The preform preparing operation <NUM>, for example, may include a process of machining a metal that will be used as a case. The metal machining process may be a process of machining a mold into a specific form by inserting a metallic preform into an injection-molding mold of a specific size, and may include a processing operation of forming a space into which an insulation member (for example, the insulation member <NUM>) (for example, a polymer resin) may be inserted. The preform preparing operation <NUM> may include at least one process of casting, rolling, extrusion, forging, full CNC, pressing, or a combination thereof.

The preform preparing operation <NUM>, for example, may include a machining process of forming an auxiliary body (for example, the auxiliary bodies <NUM>, <NUM>, <NUM>, and <NUM>) (for example, an antenna) and a main body (for example, the main bodies <NUM>, <NUM>, and <NUM>) such that the surface roughness of the auxiliary body and the surface roughness of the main body are Ra (average roughness) <NUM> to <NUM> or Rz (maximum roughness) <NUM> to <NUM>. Further, the preform preparing operation <NUM> may include a machining process of differently forming the roughness of the auxiliary body and the roughness of the main body depending on the locations of the facing surfaces of the auxiliary body and the main body. For example, the preform preparing operation <NUM> may include a metal machining process of making the roughness of an area that is covered by a front surface (for example, the front surface <NUM>) larger than the roughness of an area exposed to the outside, in the facing surfaces of the auxiliary body and the main body. Through this, various embodiments may improve a support strength by increasing an area in which a bonding layer and an insulation member are arranged in areas (having large Ra and Rz values) having relatively rough surfaces, and may couple the bonding layer and the insulation member to the auxiliary body or the main body firmer to show waterproof, dustproof, and insulation effects in areas (having small Ra or Rz values) having relatively uniform surfaces.

The adhesive coating operation <NUM> may include a pre-processing process for removing metallic impurities, oil stains, and cutting oil that are stuck to a coating target (for example, the facing surfaces of the auxiliary body and the main body and an area of the main body). The pre-processing process, for example, may include a process of removing impurities on a surface of the coating target by complexly using a surfactant degreasing solution, an alkali degreasing solution, an acid degreasing solution, or the like. According to an embodiment, in the case of aluminum, the pre-processing process may include a surfactant processing process, an alkali processing process, and an acid processing process. The adhesive coating operation <NUM> may include a process of electro-depositing a material for a bonding layer while an electric current (<NUM> to <NUM> A/dm2) to a surface of the coating target. The material used for the bonding layer, for example, may include an organic bonding material. The organic bonding layer material may be triazine thiol, dibuty amino, dithio pirymidine, or a silane-based composition, and a thickness of the coating layer may be <NUM> to <NUM>.

Further, the bonding layer may be attached to various electrified surfaces so that it may be formed even after the coating target is plated or an anodizing layer that is thin enough to be electrified is formed. Accordingly, the adhesive coating operation <NUM> may include a surface processing process such as plating or anodizing according to a purpose of the coating. Further, the adhesive coating operation <NUM> may include a process of forming an anodizing layer and a bonding layer at the same time. For example, the adhesive coating operation <NUM> may include a process of forming an anodizing oxidation layer and a complex substance film of an adhesive at the same time.

The insert injection-molding operation <NUM> may include a process of inserting a polymer resin into a bonding layer area on which the adhesive is coated.
