[0028] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the scope of the claims.

[0029] As the application scenarios for electronic devices increase, users' performance demands for electronic products are also becoming increasingly diversified. To meet these demands, more and more electronic products are beginning to improve their camera functions. However, to satisfy users' ever-growing requirements for camera capabilities, the number of components needed for camera modules has increased, which contradicts the pursuit of thinner and lighter electronic products.

[0030] To overcome the problems existing in related technologies, this disclosure provides a circuit board, a circuit board assembly, a camera assembly, an assembly method thereof, and a terminal.

[0031] This disclosure provides a circuit board, including: a plurality of first parts connected in sequence, the plurality of first parts being located on different planes, the first parts being used to connect to components; and a second part being used to connect to a power supply; wherein the first parts and the second parts are electrically connected, and the planes where the first parts are located intersect the planes where the second parts are located.

[0032] In this disclosure, multiple first parts for mounting components are configured and connected sequentially, with the multiple first parts located on different planes, and the plane of the first parts intersecting with the plane of the second part for connecting power. This configuration facilitates mounting various components on the first part of the circuit board without occupying extra space in the thickness direction of the second part.

[0033] In this disclosure, the circuit board may be a flexible printed circuit board (FPC). However, this disclosure is not limited to this; in some embodiments, it may also be a printed circuit board (PCB).

[0034] Figure 1 This is a schematic diagram illustrating the structure of a circuit board according to an exemplary embodiment. For example... Figure 1 As shown, the circuit board 10 of this disclosure may include a plurality of first parts 110 and second parts 120. The first parts 110 may be used to set up components such as capacitors and resistors.

[0035] In this disclosure, the second part 120 can be used to connect to a power source. Specifically, the second part 120 can be electrically connected to a motherboard or a small board. The motherboard or small board can be a circuit board with various functional modules inside the terminal, such as a power control module for managing the terminal's charging and discharging operations. By electrically connecting the second part 120 to the motherboard or small board, the second part 120 can be electrically connected to the power source.

[0036] In this disclosure, the second part 120 is electrically connected to the motherboard or the small board, and can transmit electrical signals with the motherboard or the small board, thereby realizing the operation of the camera component.

[0037] like Figure 1 As shown in this disclosure, the circuit board 10 may include four first parts 110, but this disclosure is not limited thereto. In other embodiments, the number of first parts 110 in the circuit board 10 may be less than four or more than four.

[0038] like Figure 1 As shown, in this disclosure, the four first parts 110 are connected sequentially and are perpendicular to each other. However, this disclosure is not limited to this; the first parts 110 connected to each other can also be at other angles, as long as they are on different planes.

[0039] In an exemplary embodiment of this disclosure, a plurality of first parts 110 are sequentially connected to form a closed loop. In this disclosure, the sequential connection of the plurality of first parts 110 to form a closed loop is beneficial for enhancing the strength of the circuit board 10 and improving the quality of the circuit board 10 and the terminal. Figure 1 As shown, the four first parts 110 can be connected in sequence to form a rectangle.

[0040] like Figure 1 As shown, the first surface 101 of the first part 110, located inside the closed loop, is used to connect to components such as capacitors and resistors. For example, one or more third pads 102 can be provided on the first surface 101. Components such as capacitors and resistors are soldered to the first part 110 of the circuit board 10 through the third pads 102. Specifically, laser soldering can be used for soldering.

[0041] Based on the same concept, this disclosure provides a circuit board assembly. Figure 2 This is a schematic diagram of a reinforcing plate according to an exemplary embodiment. Figure 3 This is a schematic diagram of the structure of a circuit board assembly according to an exemplary embodiment. Figure 4 This is a side view of a circuit board assembly according to an exemplary embodiment.

[0042] like Figure 2 , Figure 3 and Figure 4 As shown, the circuit board assembly of this disclosure may include: a circuit board 10 as described in any of the foregoing embodiments and a reinforcing plate 30. In this disclosure, the reinforcing plate 30 may be a metal plate, such as a steel plate, but this disclosure is not limited thereto; the reinforcing plate 30 may also be a component with a reinforcing function made of other materials.

[0043] In this disclosure, the reinforcing plate 30 can be a component for reinforcing the circuit board 10 or a component for reinforcing the terminal, such as a component for reinforcing the mid-frame of the terminal.

[0044] like Figure 3 and Figure 4 As shown, the reinforcing plate 30 can be disposed below the circuit board 10 and connected to the lower ends of the plurality of first parts 110. In this disclosure, the terms "below" and "above" are relative concepts, depending on the placement position of the component when it is used. When the corresponding component is flipped, "above" can also be "below," and "below" can also be "above."

[0045] In an exemplary embodiment of this disclosure, the circuit board assembly may include a chip 20, which may be disposed on the side of the reinforcing plate 30 connected to the first part 110, and a plurality of first parts 110 may be disposed around the chip 20. The chip 20 may be bonded to the reinforcing plate 30, for example, by means of an adhesive substance such as double-sided tape or foam adhesive.

[0046] In this disclosure, the chip 20 may generate a lot of heat during operation, and the reinforcing plate 30 formed by the steel sheet can play a role in heat dissipation, thereby protecting the chip 20.

[0047] In this disclosure, such as Figure 3As shown, the first part 110 can surround the chip 20. The first surface 101 of the first part 110 is arranged facing the chip 20. Components such as capacitors and resistors are arranged on the first surface 101. The middle position (lateral space) of the multiple first parts 110 arranged around it can be used to avoid occupying the longitudinal space of the circuit board assembly, thereby reducing the space occupied in the longitudinal direction and helping to reduce the size in the longitudinal direction.

[0048] Furthermore, the multiple first-part 110 surround settings provide more space in the horizontal direction, thereby increasing the space for setting up components in the horizontal space, which in turn allows for the setting up of more components and provides more functions for the camera assembly and the terminal.

[0049] like Figure 2 , Figure 3 and Figure 4 As shown in the exemplary embodiment of this disclosure, the reinforcing plate 30 is provided with a first connecting portion 301, and the first connecting portion 301 is provided with a circuit, for example, the circuit can be formed in the first connecting portion by processes such as printing, etching or printing.

[0050] like Figure 2 , Figure 3 and Figure 4 As shown in the exemplary embodiments of this disclosure, the chip 20 may be electrically connected to the first connection portion 301, and the first portion 110 may also be electrically connected to the first connection portion 301.

[0051] For example, such as Figure 2 , Figure 3 and Figure 4 As shown in the exemplary embodiment of this disclosure, the first connection portion 301 may be provided with a first pad, and the chip 20 may be electrically connected to the first pad by means of a metal wire, for example, by welding, specifically, by means of laser welding.

[0052] In an exemplary embodiment of this disclosure, a second pad may be provided at the lower end of the first part 110, and the first pad and the second pad are electrically connected, so that the first part 110 and the first connecting part 301 can be electrically connected.

[0053] Based on the same concept, this disclosure provides a camera assembly, including: a circuit board assembly as described in any of the foregoing embodiments and a bracket.

[0054] Figure 5 This is a schematic diagram of the structure of a bracket for a camera assembly according to an exemplary embodiment. Figure 6 This is an exploded view of a camera assembly according to an exemplary embodiment. Figure 5 and Figure 6As shown, the first part 110 can be disposed on the side 502 of the bracket 50.

[0055] like Figure 5 As shown, the side 502 of the bracket 50 can be the side that intersects with the upper surface 501 of the bracket 50. The circuit board 10 can be disposed around the side 502 of the bracket 50, for example, it can be disposed on the outer side 502 of the bracket 50.

[0056] like Figure 5 As shown in the exemplary embodiment of this disclosure, at least one side 502 of the support 50 where the first part 110 is provided has a cutout portion 503. The cutout portion 503 facilitates heat dissipation of the circuit board 10. Specifically, the first part 110 is provided with multiple components such as capacitors and resistors, which dissipate a large amount of heat during operation. If the temperature on the circuit board is too high, it can cause damage such as component malfunction. The cutout portion 503 can dissipate heat, thus reducing damage to the components on the circuit board caused by temperature rise.

[0057] In the exemplary embodiment of this disclosure, a protrusion 505 protruding from the side edge 502 of the bracket 50 is provided. The length of the protrusion 505 in the protruding direction can be greater than the thickness of the first part 110. This arrangement can use the protrusion 505 to limit the first part 110 of the circuit board 10, preventing the circuit board 10 from being unstable on the bracket 50, thereby improving the quality of the camera assembly.

[0058] The configuration disclosed herein, in which the first part 110 is arranged around the side of the bracket 50, can reduce the thickness of the camera assembly. A protrusion 505 is provided at the lower end of the side 502 of the bracket 50. The specific length of the protrusion 505 in the protruding direction can be specifically set according to the height of the components set on the first part 110, thereby meeting the setting requirements of various components and facilitating the realization of multiple functions of the camera assembly.

[0059] like Figure 5 As shown in the exemplary embodiment of this disclosure, a notch 504 may be provided in the protrusion 505, and a second connecting portion 103 is provided at the lower end of the first portion 110 protruding downward, and the second connecting portion 103 may be adapted to the notch 504.

[0060] This configuration facilitates the assembly of the camera components. For example, the assembly method for the camera components may include the following steps:

[0061] S11: Place the chip on the reinforcement plate;

[0062] In step S11, it can be achieved through SMT (Surface Mount Technology) process. For example, it can be a circuit assembly technology that mounts leadless or short-lead surface mount components (SMC / SMD, chip components) on the surface of a circuit board or other substrate and then solders them by reflow soldering or dip soldering.

[0063] S12: Place the first part of the circuit board on the side of the bracket;

[0064] S13: Connect the first part to the reinforcing plate.

[0065] In this disclosure, steps S11 and S12 can be performed simultaneously, which can reduce the overall assembly time of the camera assembly and improve the manufacturing efficiency of the camera assembly and the terminal.

[0066] In exemplary embodiments of this disclosure, such as Figure 6 As shown, the reinforcing plate 30 can be disposed below the bracket 50, and the second connecting part 103 is electrically connected to the reinforcing plate 30. Specifically, the second connecting part 103 can be electrically connected to the first connecting part 301 of the reinforcing plate 30.

[0067] like Figure 2 , Figure 3 and Figure 4 As shown in the exemplary embodiments of this disclosure, the chip 20 may be electrically connected to the first connection portion 301, and the first portion 110 may also be electrically connected to the first connection portion 301.

[0068] For example, such as Figure 2 , Figure 3 and Figure 4 As shown in the exemplary embodiment of this disclosure, the first connection part 301 may be provided with a first pad, and the chip 20 may be electrically connected to the first pad via a metal wire, for example, by soldering, specifically, by using laser soldering.

[0069] like Figure 6 As shown in the exemplary embodiment of this disclosure, a second pad may be provided at the lower end of the first part 110, and the first pad and the second pad are electrically connected, so that the first part 110 and the first connecting part 301 can be electrically connected.

[0070] In an exemplary embodiment of this disclosure, the camera assembly includes an infrared (IR) filter 40 disposed below the bracket 50 and above the reinforcing plate 30. For example, if the chip 20 is disposed above the reinforcing plate 30, the IR filter 40 may be disposed above the chip 20. In this disclosure, the IR filter 40 may be an infrared cut-off filter, which can prevent infrared light from passing through the camera lens and causing image distortion.

[0071] In this disclosure, the camera assembly may include a motor 60, disposed above the bracket 50. In this disclosure, the motor 60 may be a VCM (Voice Coil Motor), which is characterized by high frequency response and high precision. When applied to a terminal, the terminal can utilize the VCM to achieve autofocus, and the position of the lens can be adjusted via the VCM to present a clear image. However, this disclosure is not limited to this; in other possible embodiments, the motor may be other types of motors.

[0072] In this disclosure, the camera assembly may include a camera 70 located above the motor 60. In this disclosure, the camera may be a front-facing camera or a rear-facing camera; no specific limitation is made.

[0073] Based on the same concept, this disclosure provides a terminal. Figure 7 This is a schematic diagram of the structure of a terminal according to an exemplary embodiment, such as... Figure 7 As shown, the terminal 80 of this disclosure may include a camera component as described in any of the foregoing embodiments.

[0074] In this disclosure, multiple first parts for mounting components are configured and connected sequentially, with the multiple first parts located on different planes, and the plane of the first parts intersecting with the plane of the second part for connecting power. This configuration facilitates mounting various components on the first part of the circuit board without occupying extra space in the thickness direction of the second part.
