Description

Printed circuit boards and electronic devices comprising printed circuit boards

Various embodiments disclosed in this document relate to printed circuit boards and electronic devices including printed circuit boards.

As portable electronic devices become more high-performance, electronic components that perform various functions are placed inside the electronic devices. The electronic components are connected to the printed circuit board of the electronic device and can be controlled through a processor connected to the printed circuit board.

Meanwhile, electronic devices are becoming increasingly slimmer, and as a result, electronic components can be placed densely in a limited space. In such cases, noise can be generated between multiple electronic components.

The above information may be provided as related art for the purpose of assisting in understanding the present disclosure. No claim or determination is made as to whether any of the above is applicable as prior art related to the present disclosure.

A frame forming a side appearance of an electronic device may be used as an antenna that transmits or receives a communication signal by being electrically connected to a communication module. Electrical noise generated when transmitting or receiving a communication signal through the frame may be easily induced in an electronic component (e.g., a camera module) positioned adjacent to the frame. For example, when transmitting a communication signal, electrical noise generated in a printed circuit board connected to the communication module may be induced to an electronic component adjacent to the printed circuit board. Electrical noise generated when transmitting or receiving a communication signal may be induced to surrounding electronic components in various ways. In one embodiment, when a flexible printed circuit board connecting an electronic component and a printed circuit board comes into contact with or is in close proximity to the printed circuit board, electrical noise related to a communication signal may be induced from the printed circuit board to the flexible printed circuit board. As unnecessary electrical noise is induced to the flexible printed circuit board connected to the electronic component, malfunction or failure may occur in the electronic component. For example, when a camera module transmits or receives a communication signal, electrical noise generated on the printed circuit board may be transmitted to the flexible printed circuit board, which may interfere with signals related to the camera function transmitted from the printed circuit board, causing the camera function to malfunction.

The technical tasks to be achieved in this document are not limited to the technical tasks mentioned above, and other technical tasks not mentioned can be clearly understood by a person having ordinary knowledge in the technical field to which this document belongs from the description below.

An electronic device according to one embodiment disclosed in the present document may include an electronic component. In one embodiment, the electronic device may include a printed circuit board including a conductive layer. In one embodiment, the electronic device may include a flexible printed circuit board connecting the electronic component and the printed circuit board, the flexible printed circuit board including a first portion spaced apart from the printed circuit board by a first distance and a second portion spaced apart from the printed circuit board by a second distance less than the first distance. In one embodiment, the printed circuit board may include a first region that overlaps a second portion of the flexible printed circuit board in a direction perpendicular to one surface of the printed circuit board and from which the conductive layer is removed, and a second region excluding the first region.

An electronic device according to one embodiment disclosed in the present document may include an electronic component. In one embodiment, the electronic device may include a printed circuit board including a conductive layer. In one embodiment, the electronic device may include a flexible printed circuit board connecting the electronic component and the printed circuit board, the flexible printed circuit board including a first portion spaced apart from the printed circuit board by a first distance and a second portion spaced apart from the printed circuit board by a second distance smaller than the first distance. In one embodiment, the printed circuit board may include a first region (440A) overlapping a second portion of the flexible printed circuit board in a direction perpendicular to one surface of the printed circuit board, and a second region (440B) excluding the first region. In one embodiment, the first region of the printed circuit board may include a first layer region (441) and a second layer region (442) disposed between the first layer region and the second portion of the flexible printed circuit board and having the conductive layer removed.

According to one embodiment of the present disclosure, a printed circuit board can be electrically connected to an electronic component disposed in an electronic device through a flexible printed circuit board. In one embodiment, the flexible printed circuit board can include a first portion spaced apart from the printed circuit board by a first distance and a second portion spaced apart from the printed circuit board by a second distance smaller than the first distance. In one embodiment, the printed circuit board can include a first region overlapping a second portion of the flexible printed circuit board in a direction perpendicular to one surface of the printed circuit board, and a second region excluding the first region. In one embodiment, the first region of the printed circuit board can include a first layer region and a second layer region disposed between the first layer region and the second portion of the flexible printed circuit board and having a conductive layer removed.

According to various embodiments disclosed in the present document, a printed circuit board can be electrically connected to an electronic component through a flexible printed circuit board. The printed circuit board can include a fill cut structure in which a conductive layer is removed in an area overlapping the flexible printed circuit board. For example, the printed circuit board can have an area that can be in contact with the flexible printed circuit board composed only of an insulating layer. Accordingly, a phenomenon in which noise generated in the printed circuit board is induced into the flexible printed circuit board when the printed circuit board and the flexible printed circuit board come into contact or are in close proximity can be improved or reduced.

In addition, the printed circuit board may be configured such that a layer adjacent to the flexible printed circuit board among the areas that can come into contact with the flexible printed circuit board is configured as an insulating layer, and a layer relatively spaced from the flexible printed circuit board and arranged below the insulating layer is configured as a conductive layer on which signal wiring is formed. In this case, since the area where the flexible printed circuit board comes into contact with or is close to the printed circuit board is an area formed of an insulating material among areas of the printed circuit board, the phenomenon of noise generated in the printed circuit board being induced into the flexible printed circuit board can be improved or reduced.

The effects obtainable from the present disclosure are not limited to the effects mentioned above, and other effects not mentioned will be clearly understood by a person skilled in the art to which the present disclosure belongs from the description below.

In one embodiment, the antenna module (197) can form a mmWave antenna module. In one embodiment, the mmWave antenna module can include a printed circuit board, an RFIC positioned on or adjacent a first side (e.g., a bottom side) of the printed circuit board and capable of supporting a designated high-frequency band (e.g., a mmWave band), and a plurality of antennas (e.g., an array antenna) positioned on or adjacent a second side (e.g., a top side or a side) of the printed circuit board and capable of transmitting or receiving signals in the designated high-frequency band.

At least some of the above components may be interconnected and exchange signals (e.g., commands or data) with each other via a communication method between peripheral devices (e.g., a bus, a general purpose input and output (GPIO), a serial peripheral interface (SPI), or a mobile industry processor interface (MIPI)).

In one embodiment, commands or data may be transmitted or received between the electronic device (101) and an external electronic device (104) via a server (108) connected to a second network (199).

In one embodiment, all or part of the operations executed in the electronic device (101) may be executed in one or more of the external electronic devices (102, 104, or 108). For example, when the electronic device (101) is to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (101) may, instead of executing the function or service itself or in addition, request one or more external electronic devices to perform at least a part of the function or service. One or more external electronic devices that have received the request may execute at least a part of the requested function or service, or an additional function or service related to the request, and transmit the result of the execution to the electronic device (101). The electronic device (101) may provide the result, as is or additionally processed, as at least a part of a response to the request. For this purpose, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used, for example.

The electronic device (200) may further include at least one of a sensor module not shown, for example, a gesture sensor, a gyro sensor, a pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a color sensor, an infrared (IR) sensor, a biometric sensor, a temperature sensor, a humidity sensor, a proximity sensor, or an illuminance sensor.

The camera modules (205, 212) may include a first camera module (205) disposed on a first side (210A) of the electronic device (200), a second camera module (212) disposed on a second side (210B), and/or a flash (213). The camera modules (205, 212) may include one or more lenses, an image sensor, and/or an image signal processor. The flash (213) may include, for example, a light emitting diode or a xenon lamp. In some embodiments, two or more lenses (a wide-angle lens, an ultra-wide-angle lens, or a telephoto lens) and image sensors may be disposed on one side of the electronic device (200).

The key input device (217) may be positioned on a side (210C) of the housing (210). In one embodiment, the electronic device (200) may not include some or all of the above-mentioned key input devices (217), and the key input devices (217) that are not included may be implemented in another form, such as a soft key, on the display (201). In one embodiment, the key input device (217) may be implemented using a pressure sensor included in the display (201).

The indicator may be disposed, for example, on the first side (210A) of the housing (210). The indicator may provide, for example, status information of the electronic device (200) in the form of light (e.g., a light-emitting element). In one embodiment, the light-emitting element may provide, for example, a light source that is linked to the operation of the camera module (205). The indicator may include, for example, a light emitting diode (LED), an infrared (IR) LED, and/or a xenon lamp.

The connector hole (208) may include a first connector hole (208) that can accommodate a connector (e.g., a universal serial bus (USB) connector) for transmitting and receiving power and/or data with an external electronic device, and/or a second connector hole (or earphone jack) (not shown) that can accommodate a connector for transmitting and receiving audio signals with an external electronic device.

Some of the camera modules (205, 212), some of the sensor modules (204, 219), or the indicator may be arranged to be visually exposed through the display (201). For example, the camera module (205), the sensor module (204), or the indicator may be arranged to be in contact with the external environment through an opening or a transparent area perforated from the internal space of the electronic device (200) to the front plate (202) of the display (201). According to one embodiment, an area where the display (201) and the camera module (205) face each other may be formed as a transparent area having a certain transmittance as part of an area where content is displayed. According to one embodiment, the transparent area may be formed to have a transmittance in a range of about 5% to about 20%. Such a transparent area may include an area that overlaps with an effective area (e.g., a field of view area) of the camera module (205) through which light passes to be imaged by the image sensor to create an image. For example, the transparent area of the display (201) may include an area having a lower pixel density than the surrounding area. For example, the transparent area may replace the opening. For example, the camera module (205) may include an under display camera (UDC). In one embodiment, some of the sensor modules (204) may be arranged to perform their functions without being visually exposed through the front plate (202) in the internal space of the electronic device. For example, in such a case, the area of the display (201) that faces the sensor module may not require a perforated opening.

According to one embodiment, the electronic device (200) has a bar type or plate type appearance, but the present invention is not limited thereto. For example, the illustrated electronic device (200) may be a part of a foldable electronic device, a slidable electronic device, a stretchable electronic device, and/or a rollable electronic device. The terms "foldable electronic device", "slidable electronic device", "stretchable electronic device" and/or "rollable electronic device" may refer to an electronic device in which a display (e.g., a display (330) of FIG. 3) is capable of bending deformation, such that at least a portion thereof is folded, wound or rolled, at least a portion thereof is expanded, and/or the display can be housed inside a housing (e.g., a housing (210) of FIGS. 2A and 2B). The foldable electronic device, the slidable electronic device, the stretchable electronic device and/or the rollable electronic device can be used by expanding the screen display area by unfolding the display or exposing a wider area of the display to the outside, depending on the needs of the user.

In some embodiments, the electronic device (300) may omit at least one of the components (e.g., the first support member (311) or the second support member (360)) or may additionally include other components. At least one of the components of the electronic device (300) may be identical to or similar to at least one of the components of the electronic device (200) of FIG. 2A or FIG. 2B, and any redundant description will be omitted below.

The first support member (311) may be formed of, for example, a metal material and/or a non-metal (e.g., a polymer) material. The first support member (311) may have a display (330) coupled to one surface and a substrate (340) coupled to the other surface. The substrate (340) may be equipped with a processor (e.g., the processor (120) of FIG. 1), a memory (e.g., the memory (130) of FIG. 1), and/or an interface (e.g., the interface (177) of FIG. 1). The processor may include, for example, one or more of a central processing unit, an application processor, a graphic processing unit, an image signal processor, a sensor hub processor, or a communication processor.

The memory may include, for example, volatile memory or non-volatile memory.

In the description of the electronic device (400) described below, descriptions of configurations identical or similar to those described through FIGS. 1 to 3 are omitted.

According to one embodiment, as illustrated in FIGS. 4 and 5A, an electronic device (400) (e.g., the electronic device (101) of FIG. 1 , the electronic device (200) of FIG. 2A , and/or the electronic device (300) of FIG. 3 ) may include a housing (410) in which electronic components are placed (e.g., the housing (210) of FIG. 2A )) and a frame (420) (e.g., the side member (310) of FIG. 3 ) that surrounds a side surface of the housing (410). In one embodiment, the frame (420) may form an exterior surface of a side surface of the electronic device (400) (e.g., the side surface (210C) of FIG. 2A ). For example, the frame (420) may be arranged to surround a side surface of the housing (410) such that at least a portion of the frame (420) forms a portion of the side surface of the electronic device (400). In one embodiment, the housing (410) is disposed inside the frame (420), and electronic components constituting the electronic device (400) may be disposed. In one embodiment, the housing (410) and the frame (420) may be formed integrally. Alternatively, the frame (420) may be formed separately from the housing (410) and joined to the housing (410) through processing. According to one embodiment, the housing (410) and the frame (420) may be formed using various processing methods such as CNC (computer numerical control), die casting, or pressing.

According to one embodiment, the frame (420) may be formed of a conductive material (e.g., a metal material) and may be used as an antenna radiator. In one embodiment, the frame (420) may be electrically connected to a communication module (190) connected to a printed circuit board (440) of an electronic device (400) to transmit a communication signal (e.g., a radio frequency (RF) signal) to an external electronic device or receive a communication signal from an external electronic device.

In one embodiment, the frame (420) can be electrically connected to the printed circuit board (440) via an RF connecting member (not shown). In one embodiment, the frame (420) can include a conductive portion. The RF connecting member can be connected to the conductive portion of the frame (420). The communication module (190) is disposed on the printed circuit board (440) and can be electrically connected to the frame (420) via the RF connecting member. The RF connecting member can transmit a communication signal processed by the communication module (190) of the electronic device (400) to the frame (420) acting as an antenna, or transmit a communication signal received via the frame (420) to the communication module (190).

In one embodiment, the frame (420) can transmit or receive RF signals of various frequency bands. In one embodiment, the frame (420) is electrically connected to the communication module (190) to transmit or receive RF signals of 2.4 GHz, 5 GHz, and/or 6 GHz bands. In one embodiment, the frame (420) is electrically connected to the communication module (190) to transmit or receive RF signals of high frequency bands (e.g., 3.5 GHz to 28 GHz, 28 GHz to 100 GHz (mmWave)).

In one embodiment, electronic components may be positioned within the housing (410) adjacent to the frame (420). In one embodiment, referring to FIG. 4, a front camera (405) (e.g., the camera module (180) of FIG. 1 and/or the first camera module (205) of FIG. 2A) and a rear camera (412) (e.g., the camera module (180) of FIG. 1 and/or the second camera module (212) of FIG. 2A) may be positioned adjacent to the frame (420).

In one embodiment, the electronic components disposed in the housing (410) can be electrically connected to the printed circuit board (440) via the flexible printed circuit board (450). In one embodiment, the flexible printed circuit board (450) can be formed of a flexible material. In one embodiment, the flexible printed circuit board (450) can be physically and electrically connected to the printed circuit board (440) in various ways. In one embodiment, the connector (451) of the flexible printed circuit board (450) can be electrically connected to the printed circuit board (440) by an electrical connection method such as a soldering method, a clip method, a socket method, a bolt method, and/or a bonding method.

Meanwhile, in the process of transmitting or receiving a communication signal through the frame (420), electrical noise (e.g., electrical noise (N) of FIG. 4) may be induced to the surrounding electronic components through the printed circuit board (440). For example, in the process of transmitting a communication signal through the frame (420), a relatively higher level of power may be supplied to the printed circuit board (440) than in the process of receiving a communication signal. In particular, the printed circuit board (440) may transmit a communication signal at maximum output in order to communicate with an external electronic device in a weak electric field environment, and a relatively higher level of power may be supplied to the printed circuit board (440). In this case, electrical noise may be induced to electronic components positioned adjacent to the printed circuit board (440) from the printed circuit board (440). In one embodiment, the electrical noise may be induced directly to the electronic components. In one embodiment, the electrical noise may be induced to a flexible printed circuit board (450) connecting the electronic components and the printed circuit board (440). As electrical noise generated from the printed circuit board (440) is transmitted to the flexible printed circuit board (450), signals related to electronic components transmitted from the printed circuit board (440) may be interfered with by the electrical noise, causing malfunctions in the electronic components.

According to one embodiment, as illustrated in FIG. 4, in one embodiment, the flexible printed circuit board (450) may be connected adjacent to the printed circuit board (440) so as not to be separated from the printed circuit board (440) when an external impact (e.g., collision, dropping) is applied to the electronic device (400). For example, referring to FIG. 6 described below, the flexible printed circuit board (450) may be connected adjacent to the printed circuit board (440) in a state where at least a portion (e.g., the third portion (450C)) of the flexible printed circuit board (450) is bent. In this case, when an external impact is applied to the electronic device (400), the degree to which the flexible printed circuit board (450) can move relative to the printed circuit board (440) is reduced, so that the phenomenon of the flexible printed circuit board (450) being separated from the printed circuit board (440) can be reduced.

Meanwhile, when the flexible printed circuit board (450) and the printed circuit board (440) are disposed adjacently, the flexible printed circuit board (450) and the printed circuit board (440) may come into contact. As the flexible printed circuit board (450) comes into contact with or is close to the printed circuit board (440), electrical noise generated in the printed circuit board (440) may be induced. For example, when transmitting an antenna signal through the frame (420), a relatively high power may be generated in the printed circuit board (440). As the flexible printed circuit board (450) comes into contact with the printed circuit board (440), electrical noise associated with the antenna signal may be induced from the printed circuit board (440). As unnecessary electrical noise is induced in the flexible printed circuit board (440) and/or electronic components, the electronic components may malfunction or fail. For example, if the electronic component is a front camera (405), electrical noise may be induced from the printed circuit board (440) to the flexible printed circuit board (450), and thus, a signal related to the camera function transmitted from the printed circuit board (450) may be interfered with by the noise, causing the camera function to malfunction. In one embodiment, malfunctions that may occur in the front camera (405) may include malfunctions such as preview image interruption, video interruption, camera application operation abnormalities, and various other malfunctions.

According to one embodiment of the present disclosure, the printed circuit board (440) may include a fill cut structure in which a conductive layer (e.g., a layer formed of a conductive material, a copper layer) located at a portion that may come into contact with the flexible printed circuit board (450) is removed or omitted. For example, the printed circuit board (440) may have a conductive layer (e.g., a conductive layer (4403)) located at an area facing a portion (e.g., a second portion (450B)) of the flexible printed circuit board (450) omitted or removed. In this case, even if the flexible printed circuit board (450) comes into contact with the printed circuit board (440), electrical noise generated in the printed circuit board (440) may not be induced. Accordingly, electronic components (e.g., a front camera) connected to the flexible printed circuit board (450) may not malfunction. Hereinafter, the structure of the printed circuit board (440) that blocks the transmission of electrical noise to the flexible printed circuit board (450) will be described in detail. In addition, the flexible printed circuit board (450) is described on the premise that it is a configuration that connects the front camera (405) and the printed circuit board (440), but the following embodiment can be equally applied to the case of a flexible printed circuit board that connects the printed circuit board (440) and other electronic components other than the front camera (405).

FIG. 6 is a cross-sectional view taken along line A-A shown in FIG. 2b. FIG. 7a is a drawing of an embodiment in which a conductive layer is removed from a first region of a printed circuit board according to one embodiment of the present disclosure.

FIG. 7b is a drawing of an embodiment in which a conductive layer is removed from some layers of a first region of a printed circuit board according to one embodiment of the present disclosure.

According to one embodiment, as illustrated in FIG. 6, the flexible printed circuit board (450) may be formed of a flexible material and thus may electrically connect the printed circuit board (440) and the electronic component (e.g., a front camera) in a bent shape. In one embodiment, the flexible printed circuit board (450) may include a first portion (450A), a second portion (450B), a third portion (450C) (e.g., a bending portion) that connects the first portion (450A) and the second portion (450B) and is at least partially bent.

In one embodiment, referring to FIG. 6, the second portion (450B) may be a portion closer to an electronic component (e.g., a front camera (405)) than the first portion (450A). In one embodiment, the first portion (450A) of the flexible printed circuit board (450) may be a portion that is relatively spaced apart from the printed circuit board (440) than the second portion (450B). In one embodiment, the first portion (450A) of the flexible printed circuit board (450) may be spaced apart from the printed circuit board (440) by a first distance (H1). The second portion (450B) of the flexible printed circuit board (450) may be spaced apart from the printed circuit board (440) by a second distance (H2) that is smaller than the first distance (H1). In summary, when looking at the printed circuit board (440) in a direction perpendicular to one surface of the printed circuit board (440) (e.g., the Z-axis direction of FIG. 6), the second portion (450B) of the flexible printed circuit board (450) may be a portion that is relatively closer to the printed circuit board (440) than the first portion (450A).

According to one embodiment, the flexible printed circuit board (450) may have a higher frequency of contact with the printed circuit board (440) in the second portion (450B) than in the first portion (450A). The printed circuit board (440) may have a conductive layer (e.g., the conductive layer (4403)) used as a ground layer or a signal layer removed or omitted in a region (e.g., the first region (440A)) that overlaps the second portion (450B) of the flexible printed circuit board (450) in a direction perpendicular to one surface of the printed circuit board (440) (e.g., the +Z direction of FIG. 6) so that unnecessary electrical connections with the flexible printed circuit board (450) can be blocked. For example, referring to FIGS. 7A and 7B, the printed circuit board (440) may include a region (4403') in which the conductive layer is removed in the first region (440A). In one embodiment, the area (4403') from which the conductive layer is removed may be replaced with an insulating layer (4402). Hereinafter, as illustrated in FIGS. 5A and 6 described above, an area of the printed circuit board (440) that overlaps with a second portion (450B) of the flexible printed circuit board (450) in a direction perpendicular to one surface of the printed circuit board (440) is defined as a first area (440A), and an area remaining except for the first area (440A) is defined as a second area (440B). The first area (440A) of the printed circuit board (440) may be an area that may be in contact with the flexible printed circuit board (450).

In one embodiment, referring to FIG. 5A, the first region (440A) may be adjacent to the region where the front camera (405) is arranged, rather than the second region (440B). In one embodiment, referring to FIGS. 5A, 5B, and 5C described above, the first region (440A) may be located between fixing holes (443) into which a fixing member (e.g., the fixing member (F) of FIG. 4) for fixing the printed circuit board (440) to the housing (410) is inserted. In one embodiment, the second region (440B) of the printed circuit board (440) may be at least partially facing the first portion (450A) of the flexible printed circuit board (450).

According to one embodiment, the printed circuit board (440) may include a structure in which a plurality of layers (e.g., the first layer region (441) and the second layer region (442) of FIGS. 7A and 7B) are laminated. In one embodiment, the printed circuit board (440) may include a conductive layer (4403) (e.g., a copper layer) made of a conductive material used for power supply and ground, a solder mask (4401) (e.g., a coating layer) laminated on the upper and lower surfaces of the printed circuit board (440) to protect the conductive layer (4403), and an insulating layer (4402) formed of an insulating material (e.g., a prepreg (preimpregnated materials) layer). In one embodiment, the printed circuit board (440) may include a CCL (copper clad laminate) positioned between the plurality of prepregs.

In one embodiment, as illustrated in FIG. 5C, a sensor (501) (e.g., a proximity sensor and/or a light sensor) may be positioned adjacent to a first region (440A) of a printed circuit board (440) and positioned around a front camera (405). In one embodiment, the printed circuit board (440) may not physically remove the first region (440A) so as to secure an area where the sensor (501) is mounted, but may remove/omit at least some of the conductive layers (4403) positioned in the first region (440A).

In one embodiment, referring to FIGS. 7A and 7B, a first region (440A) of a printed circuit board (440) may include a first layer region (441) and a second layer region (442). In one embodiment, the first layer region (441) and the second layer region (442) may include a plurality of layers constituting the printed circuit board (440). In one embodiment, the second layer region (442) may be located between the first layer region (441) and a second portion (450B) of the flexible printed circuit board (450). In the following description, multiple layers (e.g., conductive layer (4403), insulating layer (4402), and/or solder mask (4401)) included in a printed circuit board (440) are divided into a first layer region (441) and a second layer region (442), but this is merely an example, and the multiple layers included in the printed circuit board (440) may be divided into various layer regions.

In one embodiment, referring to FIGS. 6 and 7A, a first region (440A) of a printed circuit board (440) may have a conductive layer (e.g., a conductive layer (4403)) removed or omitted. For example, the first region (440A) of the printed circuit board (440) may include a region (4403') from which the conductive layer is removed. In other words, the first region (440A) of the printed circuit board (440) may be composed only of an insulating material (e.g., an insulating layer (4402), a solder mask (4401)) and may not include the conductive layer (4403). For example, a first layer region (441) and a second layer region (442) of the first region (440A) may be composed only of an insulating material (e.g., an insulating layer (4402), a solder mask (4401)). In this case, the conductive layer (4403) may be located only in the second region (440B) of the printed circuit board (440). Accordingly, when the second portion (450B) of the flexible printed circuit board (450) is in contact with the first region (440A) of the printed circuit board (440), electrical noise may not be induced from the printed circuit board (440) to the flexible printed circuit board (450).

In one embodiment, referring to FIG. 7B, a first region (440A) of a printed circuit board (440) may have conductive layers (e.g., conductive layer (4403)) removed or omitted that are positioned adjacent to a second portion (450B) of a flexible printed circuit board (450). In one embodiment, the first region (440A) of the printed circuit board (440) may have conductive layers (e.g., conductive layer (4403)) removed from a layer (e.g., second layer region (442)) adjacent to a second portion (450B) of the flexible printed circuit board (450) when the printed circuit board (440) is viewed in a direction perpendicular to the printed circuit board (440) (e.g., +Z direction of FIG. 6 ). In one embodiment, a first layer region (441) that is relatively spaced apart from a second portion (450B) of a flexible printed circuit board (450) relative to a second layer region (442) may include a conductive layer (4403).

In one embodiment, referring to FIG. 7B, the first layer region (441) may include a conductive layer (4403). In one embodiment, the conductive layer (4403) of the first layer region (441) may be a signal wiring or a ground layer. Accordingly, the printed circuit board (440) may have the conductive layer (4403) removed from a layer (e.g., the second layer region (442)) adjacent to the second portion (450B) of the flexible printed circuit board (450). When the second portion (450B) of the flexible printed circuit board (450) is in contact with the first region (440A) of the printed circuit board (440), electrical noise may not be induced from the printed circuit board (440) to the flexible printed circuit board (450). Meanwhile, the conductive layer (4403) disposed in the first layer region (441) of the printed circuit board (440) may be used as a signal wiring or a ground layer.

According to one embodiment, while an area for arranging a sensor (501) on the printed circuit board (440) is secured, at least a portion of the first area (440A) of the printed circuit board (440) may be physically removed. In this case, since physical contact between the second portion (450B) of the flexible printed circuit board (450) and the printed circuit board (440) is blocked, electrical noise due to contact from the printed circuit board (440) to the flexible printed circuit board (450) may not be induced.

According to one embodiment, an insulating member (e.g., an insulating tape) formed of an insulating material may be placed between a first region (440A) of a printed circuit board (440) and a second portion (450B) of a flexible printed circuit board (450). In one embodiment, the insulating member may be attached to a surface of the first region (440A) of the printed circuit board (440) that faces the second portion (450B) of the flexible printed circuit board (450). The insulating member may block electrical noise induced from the printed circuit board (440) to the flexible printed circuit board (450).

According to one embodiment, as illustrated in FIG. 8, the flexible printed circuit board (450) may be covered by a cover member (430) (e.g., the back plate (380) of FIG. 3). In one embodiment, the flexible printed circuit board (450) may be disposed between the printed circuit board (440) and the cover member (430).
