Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to a chip component and a consumables box. Background Art

[0002] Printing information in a printer is partially stored within the printer itself, while the remaining information is stored in a chip within the consumable cartridge. Taking the ink cartridge as an example, conventional inkjet manufacturers incorporate a piezoelectric sensor circuit into the cartridge to measure the remaining ink level. The piezoelectric sensor consists of a cavity within the cartridge and a piezoelectric ceramic adhered to the cartridge. When the ink level needs to be detected, the inkjet printer sends a high-voltage current pulse signal to the piezoelectric sensor within the cartridge. This high-voltage DC pulse signal mechanically deforms the piezoelectric ceramic within the sensor circuit. The vibration of the piezoelectric ceramic resonates with the ink and air within the cartridge, generating a specific resonant frequency and charge-discharge resistance characteristics. These resonant frequency and charge-discharge resistance characteristics represent information about the ink within the cartridge and can be transmitted as sensor signals via the sensor contact terminals to the cartridge chip. From there, these signals can be sent to the printer, allowing the printer to determine the current ink level based on the different resonant frequencies and charge-discharge resistance characteristics, prompting the user to replace the cartridge when the ink level is low.

[0003] If the ink quality in the ink cartridge is poor, or the piezoelectric ceramic reed is in poor contact with the sensor contact terminal, the ink cartridge chip cannot detect the sensor signal through the sensor contact terminal, and the printer cannot receive the correct sensor signal feedback. The printer cannot obtain the ink remaining information of the ink cartridge, making the ink cartridge chip unable to be used normally on the machine and requiring a new ink cartridge to be replaced, causing unnecessary economic and time losses to consumers.

[0056] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

[0057] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0058] An embodiment of the present invention provides a chip assembly, which is applied to a consumables box. The consumables box may be, for example, printer consumables such as an ink cartridge, a toner cartridge, or a toner cartridge.

[0059] Figure 1 This is a schematic diagram of a chip assembly structure provided by an embodiment of the present utility model. Figure 2 This is a schematic structural diagram of a consumable chip provided by an embodiment of the present utility model. Figure 3 This is a schematic diagram of the structure of another chip assembly provided by the embodiment of the utility model, combined with reference Figure 1 、 Figure 2 and Figure 3The chip assembly 100 includes a consumable chip 10 and a regeneration chip 20. The consumable chip 10 includes a first surface S1 and a second surface S2. The consumable chip 10 also includes: a first controller 11 and a sensor contact terminal 12. The first controller 11 and the sensor contact terminal 12 are both disposed on the first surface S1. The regeneration chip 20 is attached to the first surface S1, and the regeneration chip 20 covers the sensor contact terminal 12. The regeneration chip 20 is electrically connected to the sensor contact terminal 12.

[0060] Specifically, the sensor contact terminal 12 is used to obtain the sensing signal, and the sensor contact terminal 12 can be electrically connected to the printer controller (not shown in the figure) to send the sensing signal to the printer controller. The sensor contact terminal 12 can be set on the same surface of the consumable chip 10 (i.e., the first surface S1) as the first controller 11. In addition, the regeneration chip 20 can be attached to the first surface S1 of the consumable chip 10, so that the regeneration chip 20 is in direct contact with the sensor contact terminal 12 to achieve a stable and reliable electrical connection. The sensing signal can be stably transmitted to the sensor contact terminal 12 through the regeneration chip 20, so that the sensor contact terminal 12 of the consumable chip 10 can always receive a relatively stable sensing signal, and the sensor contact terminal 12 will not be unable to send the sensing signal to the printer controller due to the lack of receiving the sensing signal. Therefore, when the quality of the consumables in the consumable box is poor or when the reed of the piezoelectric ceramic is in poor contact with the sensor contact terminal, the consumable box can also be put into use without having to replace a new consumable box, which can avoid unnecessary economic losses and time losses. When the regeneration chip 20 is attached to the first surface S1, the regeneration chip 20 covers the sensor contact terminal 12, allowing the regeneration chip 20 to achieve electrical connection with the sensor contact terminal 12 through direct contact without the need for additional conductive wires. This can reduce the area occupied by the consumable chip 10 and facilitate miniaturization of the consumable chip 10. The sensing signal provided by the regeneration chip 20 to the sensor contact terminal 12 can be a fixed signal with a specific resonant frequency and charge-discharge impedance characteristics simulated by a circuit. This allows the sensing signal received by the sensor contact terminal 12 to be a signal representing that the remaining consumables in the consumable box are always sufficient. This allows the consumable box to be put into use even when the consumables are of poor quality, and avoids the problem of the consumable box being unusable due to poor contact between the piezoelectric ceramic reed and the sensor contact terminal. The first controller 11 is provided with a control module and a storage module, which can implement related control functions and information storage functions.

[0061] The chip assembly provided by the embodiment of the present utility model includes a consumable chip and a regeneration chip, wherein the first controller and the sensor contact terminal in the consumable chip are both arranged on the first surface of the consumable chip. By setting an electrical connection between the sensor contact terminal and the printer controller, the first printer controller can obtain a sensing signal through the sensor contact terminal, so that the printer controller can control the printing process according to the sensing signal. By setting the regeneration chip to be attached to the first surface and setting the regeneration chip to be electrically connected to the sensor contact terminal, the sensing signal can be output to the sensor contact terminal through the regeneration chip, so that the printer controller can always obtain the sensing signal through the sensor contact terminal, so that the consumable box can be put into use even when the quality of the consumables in the consumable box is poor. It can also avoid the problem that the consumables cannot be used due to poor contact between the reed of the piezoelectric ceramic and the sensor contact terminal, and can avoid unnecessary economic losses and time losses. By setting the regeneration chip to cover the sensor contact terminal, the regeneration chip and the sensor contact terminal can be electrically connected through direct contact without having to set up a conductive wire separately, which can reduce the occupied area of ​​the consumable chip and is conducive to the miniaturization of the consumable chip.

[0062] Exemplarily, the sensor contact terminal 12 and the first controller 11 are arranged at different positions of the first surface S1 of the consumable chip 10. After the regeneration chip 20 is attached to the first surface S1 of the consumable chip 10, the orthographic projection of the regeneration chip 20 on the consumable chip 10 and the orthographic projection of the first controller 11 on the consumable chip 10 do not overlap with each other.

[0063] Exemplarily, there may be two sensor contact terminals 12, namely a first sensor contact terminal 121 and a second sensor contact terminal 122. In the prior art, a sensor is usually set between the first sensor contact terminal 121 and the second sensor contact terminal 122, so that the sensor is electrically connected to the first sensor contact terminal 121 and the second sensor contact terminal 122. The sensor obtains the sensing signal and sends it to the printer controller. This may cause the consumables in the consumable box to be of poor quality or when the reed of the piezoelectric ceramic is in poor contact with the sensor contact terminal, resulting in the inability to obtain the sensing signal or the obtained sensing signal is inaccurate, causing the consumable box to be unable to be used normally. In the embodiment of the utility model, by setting the first sensor contact terminal 121 and the second sensor contact terminal 122 of the consumable chip 10 to achieve a stable electrical connection with the regeneration chip 20, the stable sensing signal provided by the regeneration chip 20 can be always received, so that the consumable box can still be put into use when the consumables are of poor quality, and the problem of the consumable box being unusable due to poor contact between the reed of the piezoelectric ceramic and the sensor contact terminal can be avoided. Optionally, Figure 4 This is a schematic diagram of the structure of another consumable chip provided by the embodiment of the present invention, such as Figure 4As shown, the consumable chip 10 also includes: a sensing signal transmission contact 13, which is arranged on the second surface S2 and is electrically connected to the sensor contact terminal 12 through a via and / or a conductive line; a chip signal transmission contact 14, which is arranged on the second surface S2 and is electrically connected to the corresponding pin of the first controller 11 through a via and / or a conductive line; the sensing signal transmission contact 13 and the chip signal transmission contact 14 are both electrically connected to the printer controller.

[0064] Specifically, the second surface S2 of the consumable chip 10 may further be provided with a contact sensing signal transmission contact 13 corresponding to the sensor contact terminal 12. The sensing signal transmission contact 13 may include a first sensing signal transmission contact 131 and a second sensing signal transmission contact 132. Since the sensor contact terminal 12 and the sensing signal transmission contact 13 are respectively provided on two opposite sides of the consumable chip 10, the first sensing signal transmission contact 131 may be electrically connected to the first sensor contact terminal 121 through a via and / or a conductive line, and the second sensing signal transmission contact 132 may be electrically connected to the second sensor contact terminal 122 through a via and / or a conductive line. The orthographic projection of the sensor contact terminal 12 on the consumable chip 10 may be arranged to overlap with the orthographic projection of the corresponding input contact on the consumable chip 10. For example, the orthographic projection of the first sensor contact terminal 121 on the consumable chip 10 may overlap with the orthographic projection of the first sensor signal transmission contact 131 on the consumable chip 10, and the orthographic projection of the second sensor contact terminal 122 on the consumable chip 10 may overlap with the orthographic projection of the second sensor signal transmission contact 132 on the consumable chip 10. The first sensor contact terminal 121 and the first sensor signal transmission contact 131 may be electrically connected by providing a via and / or a conductive line at the overlap, and the second sensor contact terminal 122 and the second sensor signal transmission contact 132 may be electrically connected by providing a via and / or a conductive line at the overlap. In addition, the sensing signal transmission contacts 13 can also be electrically connected to the contact pins of the printer controller respectively. In this way, the sensing signal received by the first sensor contact terminal 121 can be transmitted to the printer controller through the first sensing signal transmission contact 131, and the signal received by the second sensor contact terminal 122 can be transmitted to the printer controller through the second sensing signal transmission contact 132, so that the printer controller can obtain the sensing signal.

[0065] For example, the sensor signal output by the regeneration chip 20 to the sensor contact terminal 12 can be a fixed signal to ensure that the sensor contact terminal 12 always receives a valid sensor signal, ensuring the normal operation of the ink cartridge. Since the signal received by the printer controller via the sensor contact terminal 12 is a fixed signal, the printer controller can automatically rewrite the consumable data in the consumable cartridge to control the printing process based on the rewritten consumable data. For example, if the consumable cartridge is an ink cartridge, the printer controller can detect the number of printed sheets and obtain ink level data based on the number of sheets. This allows for a relatively accurate determination of the remaining ink level to control the printing process. Similarly, ink level data can be recorded by calculating the number of ink drops. When the ink level data meets the ink-out condition, the printer reports an error and promptly stops operation. Therefore, while maintaining the consumable chip's sensor function, the present consumable chip 10 and regeneration chip 20 provide ink level data to record ink levels, enabling operation even when ink levels are low. This avoids the problem of the ink cartridge being rendered inoperable due to poor contact between the piezoelectric ceramic reed and the sensor contact terminal.

[0066] The first controller 11 may include multiple functional pins, such as a power supply pin a, a command enable pin b, a ground pin c, a communication clock pin d, and a communication data pin e. The power supply pin a receives a power signal to power the first controller 11, the ground pin g receives a ground signal, and the communication data pin i, command enable pin f, and communication clock pin h may be electrically and / or communicatively connected to the printer controller to implement data transmission, enable signal transmission, and clock signal transmission, respectively.

[0067] Corresponding to the above-mentioned functional pins, the second surface S2 of the consumable chip 10 can also be provided with corresponding chip signal transmission contacts, namely, a power supply contact 141, a command enable contact 142, a ground contact 143, a communication clock contact 144, and a communication data contact 145. The power supply contact 141 is electrically connected to the power supply pin a through a via and / or a conductive wire, the command enable contact 142 is electrically connected to the command enable pin b through a via and / or a metal wire, the ground contact 143 is electrically connected to the ground pin c through a via and / or a conductive wire, the communication clock contact 144 is electrically connected to the communication clock pin d through a via and / or a conductive wire, and the communication data contact 145 is electrically connected to the communication data pin e through a via and / or a conductive wire. Among them, the power supply contact 141 is set to be connected to the power supply contact pin on the printer side to receive the power supply voltage, and the grounding contact 143 is connected to the grounding contact pin on the printer side to receive the ground signal, and the command enable contact 142, the communication clock contact 144 and the communication data contact 145 are set to be electrically connected to the contact pins corresponding to the printer controller, so that the first controller 11 and the printer controller can realize the transmission of corresponding signals.

[0068] Optional, continue to refer to Figure 4 The consumable chip 10 also includes: a first short circuit detection contact 151 and a second short circuit detection contact 152; the first short circuit detection contact 151 and the second short circuit detection contact 152 are both arranged on the second surface S2, and the first short circuit detection contact 151 and the second short circuit detection contact 152 are electrically connected through a conductive wire.

[0069] Specifically, a conductive wire can be set on the second surface S2 to electrically connect the first short circuit detection contact 151 with the second short circuit detection contact 152. When performing a short circuit detection, the printer controller can contact the first short circuit detection contact 151 and the second short circuit detection contact 152 through a contact pin to achieve a short circuit connection of the consumable chip 10.

[0070] Optional, Figure 5 This is a schematic diagram of the structure of a regeneration chip provided by the embodiment of the utility model, combined with reference Figure 1 、 Figure 3 and Figure 5 The regeneration chip 20 includes: a third surface S3 and a fourth surface S4; the regeneration chip 20 also includes a second controller 21 and a sensor contact 22 corresponding to the sensor contact terminal 12; the sensor contact 22 is arranged on the third surface S3; the third surface S3 is in contact with the first surface S1, and the sensor contact 22 is in contact with the corresponding sensor contact terminal 12; the second controller 21 is arranged on the fourth surface S4, and the sensor contact 22 is also electrically connected to the second controller 21.

[0071] Specifically, the sensor contact 22 and the second controller 21 can be set on different surfaces of the regeneration chip 20, and the sensor contact 22 and the second controller 21 can be electrically connected through vias and / or conductive wires. The third surface S3 of the sensor contact 22 is bonded to the first surface S1 of the consumable chip 10, so that the sensor contact 22 is in direct contact with the corresponding sensor contact terminal 12 to achieve electrical connection, so that the second controller 21 can stably transmit the sensing signal to the sensor contact terminal 12 through the sensor contact 22, which can effectively avoid the situation where the sensor contact terminal 12 obtains the sensing signal from the piezoelectric ceramic sensor due to poor contact, resulting in unstable signal and inability to transmit normal data. It can ensure that the sensor contact terminal 12 always obtains a stable sensing signal, thereby not affecting the use of the consumable box. Among them, solder paste can be brushed on the sensor contact 22 of the regeneration chip 20 using the SMT process, and then the sensor contact 22 is bonded to the corresponding sensor contact terminal 12. Among them, a control module and a storage module can also be set in the second controller 21 to realize related control functions and information storage functions.

[0072] Optional, continue with reference Figure 1 、 Figure 3 and Figure 5 The regeneration chip 20 further includes: sensor connection terminals 23 corresponding to the sensor contacts 22, disposed on the fourth surface S4 and electrically connected to the output terminals of the second controller 21; the sensor connection terminals 23 are further electrically connected to the corresponding sensor contacts 22 via vias and / or conductive wires. Thus, the sensor signals output by the second controller 21 can be transmitted via the sensor connection terminals 23 to the corresponding sensor contacts 22, and then transmitted via the sensor contacts 22 to the corresponding sensor contact terminals 12 in the consumable chip 10, and then transmitted to the printer controller via the sensor signal transmission contacts 13.

[0073] Optional, continue with reference Figure 1 、 Figure 3 and Figure 5 The sensor contact 22 includes a first sensor contact 221 and a second sensor contact 222; the sensor connection terminal 23 includes a first connection terminal 231 and a second connection terminal 232; the first sensor contact 221 is electrically connected to the first connection terminal 231 through a via and / or a conductive wire; the second sensor contact 222 is electrically connected to the second connection terminal 232 through a via and / or a conductive wire.

[0074] Specifically, the second controller 21 may be provided with two corresponding signal transmission pins, one of which is connected to the first connection terminal 231 via a first conductive line L1, and the other is connected to the second connection terminal 232 via a second conductive line L2. A first via Q1 may be provided on the first conductive line L1, so that the first connection terminal 231 of the fourth surface S4 and the first sensor contact 221 of the third surface S3 can be electrically connected to the conductive line via the first via Q1. A second via Q2 may be provided on the second conductive line L2, so that the second connection terminal 232 of the fourth surface S4 and the second sensor contact 222 of the third surface S3 can be electrically connected to the conductive line via the second via Q2.

[0075] Optional, continue with reference Figure 1 、 Figure 3 and Figure 5 The orthographic projection of the first sensor contact 221 on the regeneration chip 20 is a first orthographic projection, and the orthographic projection of the second controller 21 on the regeneration chip 20 is a second orthographic projection; the first orthographic projection and the second orthographic projection at least partially overlap.

[0076] Specifically, by arranging for the first orthographic projection to at least partially overlap with the second orthographic projection, the area occupied by the first sensor contacts 221 and the second controller 21 on the regeneration chip 20 can be reduced, thereby facilitating the miniaturization of the regeneration chip 20. Furthermore, due to the provision of an insulating layer in the regeneration chip 20, when the first orthographic projection and the second orthographic projection at least partially overlap, the first sensor contacts 221 and the second controller 21 located on opposite surfaces of the regeneration chip 20 will not directly contact each other, thereby achieving insulation and preventing signal interference caused by accidental contact.

[0077] Optional, continue with reference Figure 1 、 Figure 3 and Figure 5 The orthographic projection of the second sensor contact 222 on the regeneration chip 20 is the third orthographic projection, the orthographic projection of the first connection terminal 231 on the regeneration chip 20 is the fourth orthographic projection, and the orthographic projection of the second connection terminal 232 on the regeneration chip 20 is the fifth orthographic projection; the third orthographic projection and the fourth orthographic projection at least partially overlap, and / or the third orthographic projection and the fifth orthographic projection at least partially overlap.

[0078] Specifically, the third orthographic projection can overlap with both the fourth and fifth orthographic projections, or with either the fourth orthographic projection or the fifth orthographic projection. This can reduce the area occupied by the second sensor contact 222, the first connection terminal 231, and the second connection terminal 232 of the regeneration chip 20, thereby facilitating miniaturization of the regeneration chip 20. Furthermore, due to the provision of an insulating layer in the regeneration chip 20, when the third orthographic projection overlaps with both the fourth and fifth orthographic projections, or when the third orthographic projection overlaps with either the fourth orthographic projection or the fifth orthographic projection, the second sensor contact 222 and the first connection terminal 231 will not directly contact each other, achieving insulation and thus preventing issues such as erroneous contact and signal transmission errors.

[0079] Optional, combined with reference Figure 3 and Figure 5 The regeneration chip 20 further includes: a first ground terminal 24, disposed on the fourth surface S4, electrically connected to the ground pin of the second controller 21; a second ground terminal 25, disposed on the third surface S3, electrically connected to the first ground terminal 24 through a via and a conductive wire.

[0080] Among them, the first ground terminal 24 can be electrically connected to the ground pin of the second chip 21 through the third conductive line L3, and a third via Q3 can be set on the third conductive line L3, then the second ground terminal 25 of the fourth surface S4 can be electrically connected to the first ground terminal 24 through the third via Q3 and the conductive line.

[0081] Optional, combined with reference Figure 3 and Figure 5The consumable chip 10 further includes a grounding conductor LG located on the first surface S1 and electrically connected to the ground pin c of the first controller 11; a first grounding terminal 24 electrically connected to the grounding conductor LG via a conductive line (such as the fourth conductive line L4 shown). Thus, when the printer controller provides a grounding signal to the grounding conductor of the consumable chip 10, the grounding signal is simultaneously provided to the first grounding terminal 24 and the second grounding terminal 25 of the regeneration chip 20, thereby grounding the regeneration chip 20.

[0082] Optional, reference Figure 2 and Figure 5 Alternatively, the second ground terminal 25 and the ground conductor LG may be arranged to contact each other. Specifically, when the third surface S3 of the regeneration chip 20 is attached to the consumable chip 10, the second ground terminal 25 and the ground conductor LG are positioned opposite each other, thereby directly contacting each other and achieving electrical connection between the second ground terminal 25 and the ground conductor LG. In this manner, when the printer controller provides a ground signal to the ground conductor LG of the consumable chip 10, the ground signal is simultaneously provided to both the second ground terminal 25 and the first ground terminal 24 of the regeneration chip 20, thereby grounding the regeneration chip 20.

[0083] Among them, reference Figure 2 The grounding wire LG is partially covered by an insulating layer (usually protective green oil) (as shown by the dotted line in the figure). Therefore, before attaching the regeneration chip 20 to the first surface S1 of the consumable chip 10, the insulating layer covering the portion of the grounding wire LG that will contact the second grounding terminal 25 can be removed. This ensures that after the regeneration chip 20 is attached to the first surface S1 of the consumable chip 10, the second grounding terminal 25 and the grounding wire LG are in direct contact and electrically connected. Alternatively, the second grounding terminal 25 can be directly in contact with the exposed grounding wire LG on the consumable chip 10 to form an electrical connection.

[0084] Optional, continue with reference Figure 3 and Figure 5 The regeneration chip 20 further includes: a first capacitor C1 ; the first capacitor C1 is disposed on the fourth surface S4 and electrically connected between the first connection terminal 231 and the second connection terminal 232 .

[0085] Optional, continue with reference Figure 3 and Figure 5 The regeneration chip 20 further includes: a second capacitor C2 : the second capacitor C2 is electrically connected between the power transmission pin of the second chip 21 and the first ground terminal 24 .

[0086] Figure 6 This is a schematic diagram of the circuit structure of a regeneration chip provided by the embodiment of the utility model, combined with reference Figure 3 、 Figure 5 and Figure 6 The first capacitor C1 is electrically connected between the first connection terminal 231 and the second connection terminal 232, which is equivalent to being electrically connected between the first transmission pin A1 and the second transmission pin A2 of the second controller 21. It can filter, smooth, and delay the signals transmitted by the first transmission pin A1 and the second transmission pin A2 of the second controller 21, thereby improving signal quality. Similarly, the second capacitor C2 is electrically connected between the power transmission pin HVDD of the second controller 21 and the first ground terminal 24, and can filter and stabilize the voltage of the power transmission pin HVDD.

[0087] Optional, combined with reference Figures 1 to 5 In the example, consumable chip 10 includes a first positioning hole H1 that extends through the consumable chip 10; regeneration chip 20 includes a second positioning hole H2 that extends through the regeneration chip 20. The first and second positioning holes H1 and H2 at least partially overlap. This allows positioning elements to penetrate the first and second positioning holes H1 and H2 to secure the chip assembly 100 to the consumable box, further strengthening the stable mounting of the consumable chip 10 and regeneration chip 20 and improving signal transmission stability.

[0088] Based on the same inventive concept, an embodiment of the present invention further provides a consumable box, which includes the chip assembly provided by any embodiment of the present invention. Therefore, the consumable box provided by an embodiment of the present invention includes the technical features of the chip assembly provided by any embodiment of the present invention, and can achieve the beneficial effects of the chip assembly provided by any embodiment of the present invention. The similarities can be referred to the above description of the chip assembly provided by the embodiment of the present invention, and will not be repeated here.

[0089] Illustratively, the consumables box provided in the embodiment of the present invention may be a printer consumables box, including but not limited to ink cartridges, toner cartridges, toner cartridges, and the like. Figure 7 This is a schematic diagram of the structure of a consumables box provided by an embodiment of the present invention. Figure 7 As shown, the consumable box 200 includes: a consumable box body 210 ; a chip assembly 100 fixed on a side wall 211 of the consumable box body 210 ; and a regeneration chip 20 located between the consumable chip 10 and the side wall 211 of the consumable box body 210 .

[0090] Specifically, the chip assembly 100 is preferably fixed on the outer side wall 211 of the consumable box body 210. When the chip assembly 100 is fixed on the outer side wall 211 of the consumable box body 210, the regeneration chip 20 is preferably arranged between the consumable chip 10 and the side wall 211 of the consumable box body 210, so that the regeneration chip 20 can be more stably attached to the consumable chip 10, thereby improving the stability of signal transmission.
