Description
BACKGROUND
Field

The disclosure relates to an electronic device, and for example, to an electronic device including a conductive layer.


Description of Related Art

Electronic devices may use various wireless communication technologies, such as LTE, 5G, GPS, and/or Wi-Fi, for communication with the outside. The electronic device may include an antenna for wireless communication. The antenna may be included in the electronic device as a separate member, a portion of a housing of the electronic device may be used as the antenna, or the antenna may be formed of a conductive pattern formed on a substrate part of the electronic device. In addition, the electronic device may include a shield for blocking electromagnetic noise generated from the antenna and from a controller for wireless communication. For connection with the antenna and/or the shield, the substrate part of the electronic device may include a portion where wiring is exposed, such as a connector or an electrical contact.


The electronic device may be miniaturized to improve portability and convenience. In order to miniaturize the electronic device, components such as the substrate part, the antenna, and/or the shield disposed inside the electronic device may be reduced in size and/or omitted.


There is a certain limit to reducing the area of the substrate for miniaturization of the electronic device while maintaining the performance and stability of the electronic device. Also, because such contact points on the substrate occupy the area of the substrate in order to improve the transmission and reception performance of the antenna of the electronic device and the shielding performance of the shield, the substrate may hinder miniaturization of the electronic device.

According to an embodiment, the electronic device 101 may communicate with the electronic device 104 via the server 108. According to an embodiment, the electronic device 101 may include a processor 120, memory 130, an input module 150, a sound output module 155, a display module 160, an audio module 170, a sensor module 176, an interface 177, a connecting terminal 178, a haptic module 179, a camera module 180, a power management module 188, a battery 189, a communication module 190, a subscriber identification module (SIM) 196, or an antenna module 197. In various embodiments, at least one of the components (e.g., the connecting terminal 178) may be omitted from the electronic device 101, or one or more other components may be added in the electronic device 101. In various embodiments, some of the components (e.g., the sensor module 176, the camera module 180, or the antenna module 197) may be implemented as a single component (e.g., the display module 160).


The processor 120 may include various processing circuitry and/or multiple processors. For example, as used herein, including the claims, the term “processor” may include various processing circuitry, including at least one processor, wherein one or more of at least one processor, individually and/or collectively in a distributed manner, may be configured to perform various functions described herein. As used herein, when “a processor”, “at least one processor”, and “one or more processors” are described as being configured to perform numerous functions, these terms cover situations, for example and without limitation, in which one processor performs some of recited functions and another processor(s) performs other of recited functions, and also situations in which a single processor may perform all recited functions. Additionally, the at least one processor may include a combination of processors performing various of the recited/disclosed functions, e.g., in a distributed manner. At least one processor may execute program instructions to achieve or perform various functions.

The cross-sectional view of FIG. 5C is a cross-sectional view taken along the A-A′ direction of FIG. 5A.


With reference to FIGS. 5A, 5B and 5C (which may be referred to as FIGS. 5A to 5C), the substrate part 501 of the electronic device (e.g., the electronic device 101 in FIGS. 1 to 4) may include a printed circuit board 510 (e.g., the printed circuit board 480 in FIG. 4) and a conductive layer 520. The printed circuit board 510 may be a member having at least one surface (e.g., a surface facing the z-axis direction) on which electrical components 502 of the electronic device, such as an integrated circuit (IC) 502a and an active or passive component 502b, are arranged. The IC 502a may include, for example, an application processor (AP), a display driver IC (DDI), a power management IC (PMIC), and/or a communication chipset (e.g., a modem).

The conductive layer 520 may be a portion having a conductive material (e.g., copper, aluminum, and/or carbon black) and being electrically connected to the wiring exposure part 512. The conductive layer 520 may include a shielding member 521 that shields the electrical components 502 disposed on the printed circuit board 510 from electromagnetic interference (EMI) caused by external and/or other electrical components 502.

Therefore, the shielding member 521 can shield the electronic device from electromagnetic interference by allowing electromagnetic energy that is introduced into the electronic device from the outside or generated from the electrical components 502, such as an RF circuit, to flow through the ground circuit.


With reference to FIGS. 5A and 5C, in various embodiments, the substrate part 501 of the electronic device may include a molding part 530. The molding part 530 may be disposed to at least partially cover a surface of the printed circuit board 510 on which the electrical components 502 are arranged, and may be a member that protects the electrical components 502 of the printed circuit board 510 from external physical impact and/or improves insulation to prevent and/or reduce a failure such as a short circuit.

With reference to FIGS. 7A, 7B and 7C (which may be referred to as FIGS. 7A to 7C), in various embodiments, the conductive layer 520 of the substrate part 501 may include a conductive pattern 522. The conductive pattern 522 may be a member electrically spaced from the shielding member 521 with an insulating region 523 therebetween. In various embodiments, the conductive pattern 522 may be located on the lateral surface of the substrate part 501 and the molding part 530. In various embodiments, the conductive pattern 522 may extend from the lateral surface of the molding part 530 to the upper surface of the molding part 530.


In various embodiments, the conductive pattern 522 may include a contact pad 522a and/or an antenna pattern 522b. With reference to FIG. 7D, the contact pad 522a may be a member for connecting the printed circuit board 510 to a component, such as an antenna structure 601, disposed outside the substrate part 501. The antenna structure 601 may be electrically connected to the contact pad 522a through a mechanical member, such as a C-clip 602, or may be connected to the contact pad 522a through a bonding member, such as soldering or surface mount technology (SMT). The contact pad 522a may be electrically connected to, for example, the wiring 511 for wireless communication, thereby electrically connecting the antenna structure 601 and a wireless communication module (e.g., the wireless communication module 192 in FIG. 1).


With reference to FIG. 7E, the insulating region 523 that electrically isolates the conductive pattern 522 and the shielding member 521 may be formed by removing a portion of a conductive material 529 coated on the surface of the molding part 530. The conductive layer 520 including the conductive pattern 522 and the shielding member 521 may be formed by coating the conductive material 529 on the surface of the molding part 530. When the conductive material 529 is removed from the insulating region 523, the insulating region 523 exposes the molding part 530, and current cannot flow through the insulating region 523 because the molding part 530 has a non-conductive material (e.g., acrylic resin). Therefore, the insulating region 523 through which current cannot flow may be formed between the conductive pattern 522 and the shielding member 521. The insulating region 523 may be formed on the lateral surface and/or the upper surface of the molding part. For example, as a tool for removing the conductive material 529 to form the insulating region 523, mechanical processing such as milling, chemical removal such as etching, and/or laser cutting may be used.
