Description

Technical Field

[0001] The present disclosure relates to the field of terminal technology, and in particular to a circuit board and an electronic device. Background Art

[0002] Some current electronic devices are equipped with antennas for receiving signals.

[0003] For example, in a mobile phone, the antenna and the middle frame of the mobile phone are usually an integrally formed structure, and the matching circuit and antenna connector corresponding to the antenna are integrated on the circuit board. When the circuit board and the middle frame are assembled, the antenna on the middle frame is electrically connected to the antenna connector set at the corresponding position, thereby realizing the electrical connection between the antenna and the matching circuit through the antenna connector.

[0004] For some electronic devices currently produced that have similar configurations but different sizes, the configurations on the circuit board except for the antenna connector are similar or the same. However, due to the different sizes of the middle frames of electronic devices of different sizes, the positions of the antennas of electronic devices of different sizes are also different, and thus the positions of the antenna connectors corresponding to the antenna positions are also different. Therefore, due to the antennas, electronic devices of different sizes need to be provided with their own corresponding circuit boards so that the antenna connectors on the circuit board correspond to the positions of the antennas. However, this consumes a lot of R&D time, R&D resources and R&D costs, and reduces the development efficiency of electronic equipment. Summary of the invention

[0056] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0057] The present disclosure provides a circuit board, such as Figure 1 As shown, the circuit board 100 includes a substrate 11 , a first connector pad 12 , a second connector pad 13 and a matching circuit pad 14 .

[0058] The first connector pad 12 , the second connector pad 13 and the matching circuit pad 14 are all located on the surface of the substrate 11 and connected to the substrate 11 .

[0059] The substrate 11, the first connector pad 12, the second connector pad 13 and the matching circuit pad 14 are introduced below respectively:

[0060] Substrate 11

[0061] The substrate 11 includes a first plate portion 111 and a second plate portion 112, and the side of the first plate portion 111 is connected to the side of the second plate portion 112, wherein the first plate portion 111 and the second plate portion 112 can be an integrally formed structure, and the first plate portion 111 and the second plate portion 112 can form a plate-like structure with an irregular shape.

[0062] The first plate portion 111 and the second plate portion 112 may be of any reasonable shape, and the shapes of the first plate portion 111 and the second plate portion 112 may be set according to the shape of the terminal and the shape of the mounting area of ​​the circuit board, which is not limited in the embodiments of the present disclosure.

[0063] For example, the first board portion 111 and the second board portion 112 may both be rectangular, and the substrate 11 including the first board portion 111 and the second board portion 112 may be a spliced ​​shape of rectangles of different sizes. The first board portion 111 is used to connect the first connector pad 12, the matching circuit pad 14, and other devices provided in the terminal where the circuit board 100 is located, and the second board portion 112 is used to connect the second connector pad 13, which is described later. Compared with the first board portion 111, the area of ​​the second board portion 112 can be set relatively small.

[0064] In a possible implementation, in order to facilitate the staff to divide the area of ​​the first plate portion 111 and the second plate portion 112 included in the substrate 11, a cutoff line can be drawn or etched at the boundary of the first plate portion 111 and the second plate portion 112 to facilitate the staff to distinguish, for example, Figure 1 In the circuit board 100 shown, the dotted line between the first board portion 111 and the second board portion 112 may be the cutoff line.

[0065] The first connector pad 12 and the second connector pad 13

[0066] The first connector pad 12 is connected to a region of the first board portion 111 close to the second board portion 112 , and is configured to be electrically connected to the first antenna connector 200 .

[0067] That is, the first connector pad 12 is fixed to the first board portion 111 at a position close to the second board portion 112, for example, Figure 1 As shown, the first connector pad 12 is located on the right side of the cutoff line and in an area closer to the second board portion 112 .

[0068] The second connector pad 13 is connected to a region of the second board portion 112 close to the first connector pad 12 , and is configured to be electrically connected to the second antenna connector 300 .

[0069] That is, the second connector pad 13 is fixed to the second board portion 112 at a position close to the first board portion 111, for example, Figure 1 As shown, the second connector pad 13 is located on the left side of the cutoff line and in an area closer to the first board portion 111 .

[0070] When it is necessary to produce two electronic devices with similar product configurations but different sizes, the circuit board 100 provided in the embodiment of the present disclosure may be used.

[0071] When it is necessary to produce an electronic device of smaller size, in order to make the circuit board 100 more adaptable to the antenna set on the middle frame of the electronic device, the circuit board 100 can be cut along the position of the cut-off line, and the second board portion 112 can be milled off from the circuit board 100 to reduce the size of the circuit board 100. The size of the obtained first board portion 111 is adapted to the middle frame of the electronic device.

[0072] It is understandable that, after the second board portion 112 is milled off from the circuit board 100 , the second connector pad 13 provided on the second board portion 112 is also removed from the circuit board 100 along with the second board portion 112 .

[0073] After obtaining the circuit board 100 with the second board portion 112 milled off, the first connector pad 12 can be electrically connected to the first antenna connector 200 , that is, the first antenna connector 200 is attached to the first connector pad 12 .

[0074] It can be understood that the first antenna connector 200 installed at this time is an antenna connector adapted to the antenna provided on the middle frame of the electronic device of smaller size. After the circuit board 100 with the first antenna connector 200 installed is installed at a relative position of the middle frame of the electronic device, the first antenna connector 200 contacts the antenna provided on the middle frame to achieve electrical connection.

[0075] When a larger electronic device needs to be produced, the size of the circuit board 100 including the first board portion 111 and the second board portion 112 is just the size that fits the middle frame of the electronic device, so it is not necessary to mill off the second board portion 112. The second connector pad 13 can be directly electrically connected to the second antenna connector 300, that is, the second antenna connector 300 is attached to the second connector pad 13.

[0076] It is understandable that the second antenna connector 300 installed at this time is an antenna connector adapted to the antenna provided on the middle frame of the electronic device of larger size. After the circuit board 100 with the second antenna connector 300 installed is installed at a relative position of the middle frame of the electronic device, the second antenna connector 300 contacts the antenna provided on the middle frame to achieve electrical connection.

[0077] When the type of antenna on the middle frame of an electronic device with smaller size and corresponding to the first antenna connector 200 is the same as the type of antenna on the middle frame of an electronic device with larger size and corresponding to the second antenna connector 300, the types of the first antenna connector 200 and the second antenna connector 300 may be the same or different, and the embodiments of the present disclosure are not limited to this.

[0078] When the type of antenna on the middle frame of an electronic device with a smaller size and corresponding to the first antenna connector 200 is different from the type of antenna on the middle frame of an electronic device with a larger size and corresponding to the second antenna connector 300, usually, the types of the first antenna connector 200 and the second antenna connector 300 are also different. Of course, if different types of antennas on two electronic devices of different sizes can share an antenna connector, the types of the first antenna connector 200 and the second antenna connector 300 can be the same, and the types of the first antenna connector 200 and the second antenna connector 300 can be selected according to needs, and the embodiments of the present disclosure are not limited to this.

[0079] When it is necessary to produce multiple electronic devices with similar product configurations but different sizes, the substrate 11 may include other board portions in addition to the first board portion 111 and the second board portion 112. The other board portions are located on a side of the second board portion 112 away from the first board portion 111 and are connected to the second board portion 112.

[0080] For example, when it is necessary to produce three electronic devices with similar product configurations but different sizes, the substrate 11 may include a first board portion 111, a second board portion 112 and a third board portion, wherein the first board portion 111 and the third board portion are located on both sides of the second board portion 112, and their sides are connected to the sides of the second board portion 112. Among them, a first connector pad 12 is provided in the area of ​​the first board portion 111 close to the second board portion 112, a second connector pad 13 is provided on the second board portion 112, and a third connector pad is provided in the area of ​​the third board portion close to the second board portion 112, which are respectively used to connect antenna connectors corresponding to antennas provided on the middle frames of electronic devices of different sizes.

[0081] Matching circuit pad 14

[0082] The matching circuit pad 14 is connected to the first board portion 111 , and may be located in a region of the first board portion 111 close to the first connector pad 12 and the second connector pad 13 , so as to be electrically connected to the first connector pad 12 and the second connector pad 13 .

[0083] The matching circuit pad 14 can be electrically connected to the first connector pad 12 and / or the second connector pad 13, that is, the matching circuit pad 14 can be electrically connected to the first connector pad 12 and not electrically connected to the second connector pad 13, or, the matching circuit pad 14 can be not electrically connected to the first connector pad 12 and be electrically connected to the second connector pad 13, or, the matching circuit pad 14 is electrically connected to both the first connector pad 12 and the second connector pad 13.

[0084] The matching circuit pad 14 is used to be electrically connected to the first matching circuit 400 corresponding to the first connector pad 12 or the second matching circuit 500 corresponding to the second connector pad 13 .

[0085] When it is necessary to produce two electronic devices with similar product configurations but different sizes, the circuit board 100 provided in the embodiment of the present disclosure may be used.

[0086] When it is necessary to produce an electronic device of smaller size, in addition to setting the substrate 11 and the first connector pad 12 introduced above, it is also necessary to electrically connect the matching circuit pad 14 with the first matching circuit 400 corresponding to the first connector pad 12 (the first matching circuit 400 corresponds to the first connector pad 12, the first antenna connector 200, and the antenna arranged on the middle frame of the electronic device of smaller size). In this way, the first matching circuit 400, the first antenna connector 200 and the antenna on the middle frame of the electronic device are all electrically connected, thereby realizing the function of the antenna.

[0087] When it is necessary to produce an electronic device of a larger size, in addition to setting the substrate 11 and the second connector pad 13 introduced above, it is also necessary to electrically connect the matching circuit pad 14 with the second matching circuit 500 corresponding to the second connector pad 13 (the second matching circuit 500 corresponds to the second connector pad 13, the second antenna connector 300, and the antenna set on the middle frame of the larger electronic device). In this way, the second matching circuit 500, the second antenna connector 300 and the antenna on the middle frame of the electronic device are all electrically connected, thereby realizing the function of the antenna.

[0088] It is understandable that the matching circuit pad 14 needs to be compatible with the first matching circuit 400 and the second matching circuit 500 , that is, the compatible circuit corresponding to the matching circuit pad 14 needs to be compatible with the first matching circuit 400 and the second matching circuit 500 .

[0089] Among the devices in the compatible circuit, some devices may be shared by the first matching circuit 400 and the second matching circuit 500 , some devices may be unique to the first matching circuit 400 , and some devices may be unique to the second matching circuit 500 .

[0090] The compatible circuit corresponding to the matching circuit pad 14 includes multiple lines, and the devices on each line are connected in series. The multiple lines can be connected in series or in parallel. When the matching circuit pad 14 is electrically connected to the first matching circuit 400 or the second matching circuit 500, the electrical connection with the first matching circuit 400 or the second matching circuit 500 can be achieved by controlling the conduction or disconnection of the lines in the compatible circuit and whether the devices are used.

[0091] For example, when the first matching circuit 400 needs to be implemented, the pads corresponding to the unnecessary devices in the series circuit of the compatible circuit (devices unique to the second matching circuit 500 and not shared with the first matching circuit 400) can be electrically connected to the zero-ohm resistor, and the pads corresponding to the unnecessary lines in the parallel circuit of the compatible circuit are not electrically connected to the corresponding devices, so that the unnecessary lines cannot be turned on. The operation when the second matching circuit 500 needs to be implemented is similar to the above, and the embodiments of the present disclosure will not be repeated.

[0092] In summary, the embodiment of the present disclosure provides a circuit board 100 , which can provide connector pads at at least two different positions, namely, a first connector pad 12 and a second connector pad 13 .

[0093] like Figure 2As shown, when the size of the electronic device is small, the second board portion 112 on the circuit board 100 can be milled off, and then the first connector pad 12 set on the first board portion 111 is used to connect the first antenna connector 200, so that the first antenna connector 200 corresponds to the position of the antenna on the middle frame, and the matching circuit pad 14 is electrically connected to the first matching circuit 400 corresponding to the first antenna connector 200, so that the electrical connection between the antenna on the middle frame and the first matching circuit 400 is achieved through the matching circuit pad 14, the first connector pad 12 and the first antenna connector 200.

[0094] like Figure 3 As shown, when the size of the electronic device is larger, the second connector pad 13 set on the second board portion 112 can be used to connect the second antenna connector 300, so that the second antenna connector 300 corresponds to the position of the antenna on the middle frame, and the matching circuit pad 14 is electrically connected to the second matching circuit 500 corresponding to the second antenna connector 300, so that the electrical connection between the antenna on the middle frame and the second matching circuit 500 is achieved through the matching circuit pad 14, the second connector pad 13 and the second antenna connector 300.

[0095] By using the circuit board 100 provided in the present disclosure, the requirement of using a common circuit board for electronic devices of at least two sizes can be met, thereby reducing the consumption of R&D time, R&D resources and R&D costs, and improving the development efficiency of electronic devices.

[0096] In the circuit board 100 provided in the embodiment of the present disclosure, there are many possible electrical connection settings between the matching circuit pad 14 and the first connector pad 12 and the second connector pad 13, and several possible implementations are introduced below:

[0097] The first circuit board 100

[0098] like Figure 4 As shown, the circuit board 100 may include a first connection terminal pad 15, which is connected to an area of ​​the first board portion 111 close to the second board portion 112, and the first connection terminal pad 15 is electrically connected to the matching circuit pad 14, and is used to be electrically connected to the first connector pad 12 or the second connector pad 13 through the first jumper matching component 600.

[0099] In a possible implementation, the circuit board 100 may further include a second connection terminal pad 16 and a third connection terminal pad 17 .

[0100] The second connection terminal pad 16 is connected to the area of ​​the first board portion 111 close to the first connection terminal pad 15, and the second connection terminal pad 16 is electrically connected to the first connector pad 12. The second connection terminal pad 16 can be electrically connected to the first connection terminal pad 15 through the first jumper matching component 600, thereby realizing the electrical connection between the first connector pad 12 and the matching circuit pad 14.

[0101] The third connection terminal pad 17 is connected to the area of ​​the second board portion 112 close to the first connection terminal pad 15, and the third connection terminal pad 17 is electrically connected to the second connector pad 13. The third connection terminal pad 17 can be electrically connected to the first connection terminal pad 15 through the first jumper matching component 600, thereby realizing the electrical connection between the second connector pad 13 and the matching circuit pad 14.

[0102] In a possible implementation, the first jumper matching component 600 may be any reasonable device, for example, it may be any one of a capacitor, a resistor, and an inductor, which is not limited in the embodiment of the present disclosure.

[0103] When it is necessary to produce two electronic devices with similar product configurations but different sizes, the circuit board 100 described above can be set as follows:

[0104] like Figure 5 As shown, when it is necessary to produce an electronic device of smaller size, the second board portion 112 in the substrate 11 is milled off, the first connector pad 12 is electrically connected to the first antenna connector 200, the matching circuit pad 14 is electrically connected to the first matching circuit 400, and the first connection end pad 15 is electrically connected to the second connection end pad 16 using the first jumper matching component 600, thereby realizing the electrical connection between the first antenna connector 200 and the first matching circuit 400, thereby forming a circuit board assembly. In this way, after the circuit board assembly is installed on the middle frame of the electronic device, the first antenna connector 200 contacts the antenna at the corresponding position on the middle frame to realize electrical connection, thereby realizing the electrical connection between the first matching circuit 400 and the antenna.

[0105] like Figure 6As shown, when it is necessary to produce an electronic device of smaller size, the substrate 11 can be used directly without milling off the second board portion 112 on the substrate 11, and the second connector pad 13 is electrically connected to the second antenna connector 300, the matching circuit pad 14 is electrically connected to the second matching circuit 500, and the first jumper matching component 600 is used to electrically connect the first connection end pad 15 to the third connection end pad 17, thereby realizing the electrical connection between the second antenna connector 300 and the second matching circuit 500, thereby forming a circuit board assembly. In this way, after the circuit board assembly is installed on the middle frame of the electronic device, the second antenna connector 300 contacts the antenna at the corresponding position on the middle frame to realize electrical connection, thereby realizing the electrical connection between the second matching circuit 500 and the antenna.

[0106] In this circuit board 100, the matching circuit pad 14 is not electrically connected to the first connector pad 12 and the second connector pad 13, but the electrical connection is subsequently achieved through the first jumper matching component 600. This structure is more convenient for controlling the electrical connection between the matching circuit pad 14 and the first connector pad 12 and the second connector pad 13, and the arranged routing is shorter, and the loss and impedance can be controlled within a smaller range, thereby improving the signal quality of the antenna.

[0107] Second circuit board 100

[0108] like Figure 7 As shown, the circuit board may further include a connecting wire 18 , the two ends of the connecting wire 18 are electrically connected to the matching circuit pad 14 and the second connector pad 13 respectively, and the middle portion between the two ends of the connecting wire 18 is electrically connected to the first connector pad 12 .

[0109] In the embodiment of the present disclosure, the connector pad (first connector pad 12 or second connector pad 13) may include one pad or two sub-pads, and may be configured differently according to the type of the antenna connector (first antenna connector 200 or second antenna connector 300). When the connector pad includes two sub-pads, after the connector pad is electrically connected to the antenna connector, both sub-pads may be electrically connected to the antenna connector.

[0110] In one possible implementation, Figure 8 As shown, the first connector pad 12 includes two sub-pads 121, and the connecting wire 18 is electrically connected to both sub-pads 121. In this way, when the second connector pad 13 is electrically connected to the second antenna connector 300, the connecting wire 18 is electrically connected to both sub-pads 121 in the first connector pad 12, which can avoid the adverse effect of the other sub-pad on the antenna signal when the connecting wire 18 is electrically connected to only one of the sub-pads.

[0111] In one possible implementation, Figure 8 As shown, there is a first gap between the two sub-pads 121, and the orthographic projection of the connecting line 18 on the substrate 11 at least partially overlaps with the orthographic projection of the first gap on the substrate 11 and the orthographic projection of the two sub-pads 121 on the substrate 11. This arrangement reduces the length of the connecting line 18, thereby improving the signal quality of the antenna.

[0112] It is understandable that, in order to facilitate display of the overlapping portion between the orthographic projection of the connection line 18 on the substrate 11 and the orthographic projection of the first gap on the substrate 11 and the orthographic projection of the two sub-pads 121 on the substrate 11 , the connection line 18 is not pattern-filled.

[0113] When it is necessary to produce two electronic devices with similar product configurations but different sizes, the circuit board 100 described above can be set as follows:

[0114] like Fig. 9 As shown, when it is necessary to produce an electronic device of smaller size, the second board portion 112 in the substrate 11 is milled off, and the second board portion 112 and part of the line segments of the connecting line 18 set on the second board portion 112 are also milled off together. Then, the first connector pad 12 is electrically connected to the first antenna connector 200, and the matching circuit pad 14 is electrically connected to the first matching circuit 400, so that the electrical connection between the first antenna connector 200 and the first matching circuit 400 can be achieved, thereby forming a circuit board assembly. In this way, after the circuit board assembly is installed on the middle frame of the electronic device, the first antenna connector 200 contacts the antenna at the corresponding position on the middle frame to achieve electrical connection, thereby achieving electrical connection between the first matching circuit 400 and the antenna.

[0115] like Fig.10 As shown, when it is necessary to produce an electronic device of smaller size, the substrate 11 can be used directly without milling off the second board portion 112 on the substrate 11. The second connector pad 13 is electrically connected to the second antenna connector 300, and the matching circuit pad 14 is electrically connected to the second matching circuit 500, thereby realizing the electrical connection between the second antenna connector 300 and the second matching circuit 500, thereby forming a circuit board assembly. In this way, after the circuit board assembly is installed on the middle frame of the electronic device, the second antenna connector 300 contacts the antenna at the corresponding position on the middle frame to realize electrical connection, thereby realizing the electrical connection between the second matching circuit 500 and the antenna.

[0116] In this circuit board 100 , no connection terminal pad is provided, and the distance between the first connector pad 12 and the second connector pad 13 is relatively large, so the first connector pad 12 is not easily affected when the second board portion 112 is milled off.

[0117] The third circuit board 100

[0118] like Fig.11 As shown, the circuit board further includes a fourth connection terminal pad 19 and a fifth connection terminal pad 20 .

[0119] The fourth connection terminal pad 19 is connected to a region of the first board portion 111 close to the second board portion 112 , and the fourth connection terminal pad 19 is electrically connected to both the first connector pad 12 and the matching circuit pad 14 .

[0120] The fifth connection terminal pad 20 is connected to the area of ​​the second board portion 112 close to the fourth connection terminal pad 19, the fifth connection terminal pad 20 is electrically connected to the second connector pad 13, there is a second gap between the fifth connection terminal pad 20 and the fourth connection terminal pad 19, and the fifth connection terminal pad 20 can be electrically connected to the fourth connection terminal pad 19 through a second jumper matching component 700.

[0121] When it is necessary to produce two electronic devices with similar product configurations but different sizes, the circuit board 100 described above can be set as follows:

[0122] like Fig.12 As shown, when it is necessary to produce an electronic device of smaller size, the second board portion 112 in the substrate 11 is milled off, the first connector pad 12 is electrically connected to the first antenna connector 200, and the matching circuit pad 14 is electrically connected to the first matching circuit 400, thereby realizing the electrical connection between the first antenna connector 200 and the first matching circuit 400, thereby forming a circuit board assembly. In this way, after the circuit board assembly is installed on the middle frame of the electronic device, the first antenna connector 200 contacts the antenna at the corresponding position on the middle frame to realize electrical connection, thereby realizing the electrical connection between the first matching circuit 400 and the antenna.

[0123] like Fig.13 As shown, when it is necessary to produce an electronic device of smaller size, the substrate 11 can be used directly without milling off the second board portion 112 on the substrate 11, and the second connector pad 13 is electrically connected to the second antenna connector 300, the matching circuit pad 14 is electrically connected to the second matching circuit 500, and the fourth connection terminal pad 19 and the fifth connection terminal pad 20 are electrically connected using the second jumper matching component 700, thereby realizing the electrical connection between the second antenna connector 300 and the second matching circuit 500, thereby forming a circuit board assembly. In this way, after the circuit board assembly is installed on the middle frame of the electronic device, the second antenna connector 300 contacts the antenna at the corresponding position on the middle frame to realize electrical connection, thereby realizing the electrical connection between the second matching circuit 500 and the antenna.

[0124] In this circuit board 100, no connection terminal pad is provided, and the matching circuit pad 14 is not electrically connected to the second connector pad 13. Instead, the electrical connection is subsequently realized through the second jumper matching component 700. This structure makes it easier to control the electrical connection between the matching circuit pad 14 and the first connector pad 12 and the second connector pad 13.

[0125] In a possible implementation, the second gap is greater than or equal to a preset distance, which needs to cover the sum of the cutoff line and the processing tolerance to avoid affecting the fourth connection terminal pad 19 and the fifth connection terminal pad 20 when milling off the second plate portion 112 .

[0126] In a possible implementation, the second jumper matching member 700 may be packaged in 0603 or 0402, and the second gap corresponds to the second jumper matching member 700. For example, Fig.11 The second jumper matching component 700 in the circuit board 100 shown is packaged in 0402. Fig.14 The second jumper matching component 700 in the circuit board 100 shown adopts the 0603 package. It can be obviously seen that the gap between the fourth connection terminal pad 19 and the fifth connection terminal pad 20 using the 0603 package is larger and the occupied area is also larger, and the gap between the fourth connection terminal pad 19 and the fifth connection terminal pad 20 using the 0402 package is smaller and the occupied area is also smaller. Different selections can be made according to needs, and the embodiments of the present disclosure are not limited to this.

[0127] The embodiment of the present disclosure further provides a processing method of a circuit board assembly, the processing method is applied to the circuit board assembly, the circuit board assembly includes a first antenna connector 200, a second antenna connector 300, a first matching circuit 400 corresponding to the first antenna connector 200, a second matching circuit 500 corresponding to the second antenna connector 300, and the circuit board 100 described in any one of the above items, the processing method includes:

[0128] When it is necessary to process a circuit board assembly corresponding to an electronic device of smaller size, the second board portion 112 in the circuit board 100 can be milled off, the first connector pad 12 can be electrically connected to the first antenna connector 200 and the matching circuit pad 14, and the matching circuit pad 14 can be electrically connected to the first matching circuit 400.

[0129] When a circuit board assembly corresponding to an electronic device of larger size needs to be processed, there is no need to mill off the second board portion 112. The second connector pad 13 can be directly electrically connected to the second antenna connector 300 and the matching circuit pad 14, and the matching circuit pad 14 can be electrically connected to the second matching circuit 500.

[0130] The embodiment of the present disclosure further provides an electronic device, which includes any of the above-mentioned circuit boards 100. For example, the electronic device may be a mobile phone, a laptop computer, etc., which is not limited in the embodiment of the present disclosure.

[0131] The circuit board 100 provided in the embodiment of the present disclosure can adapt to electronic devices of different sizes. When the size of the electronic device is small, the second plate portion 112 on the circuit board 100 can be milled off to adapt it to the size of the electronic device. When the size of the electronic device is large, the circuit board 100 can be used directly to adapt to its larger size. In this way, the need for electronic devices of at least two sizes to share the circuit board is met, thereby reducing the consumption of R&D time, R&D resources and R&D costs, and improving the development efficiency of electronic devices.

[0132] The technical solution provided by the embodiments of the present disclosure includes at least the following beneficial effects:

[0133] The embodiment of the present disclosure provides a circuit board 100 , which can provide connector pads at at least two different positions, namely, a first connector pad 12 and a second connector pad 13 .

[0134] When the size of the electronic device is small, the second board portion 112 on the circuit board 100 can be milled off, and then the first connector pad 12 set on the first board portion 111 can be used to connect the first antenna connector 200, so that the position of the first antenna connector 200 corresponds to the antenna on the middle frame, and the matching circuit pad 14 is electrically connected to the first matching circuit 400 corresponding to the first antenna connector 200, so that the electrical connection between the antenna on the middle frame and the first matching circuit 400 is achieved through the matching circuit pad 14, the first connector pad 12 and the first antenna connector 200.

[0135] When the size of the electronic device is larger, the second connector pad 13 set on the second board portion 112 can be used to connect the second antenna connector 300, so that the second antenna connector 300 corresponds to the position of the antenna on the middle frame, and the matching circuit pad 14 is electrically connected to the second matching circuit 500 corresponding to the second antenna connector 300, so that the electrical connection between the antenna on the middle frame and the second matching circuit 500 is achieved through the matching circuit pad 14, the second connector pad 13 and the second antenna connector 300.

[0136] By using the circuit board 100 provided in the present disclosure, the requirement of using a common circuit board for electronic devices of at least two sizes can be met, thereby reducing the consumption of R&D time, R&D resources and R&D costs, and improving the development efficiency of electronic devices.
