CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This non-provisional application claims priority under 35 U.S.C. §119(a) on Patent Application No(s). 201210505402.8 filed in China, P.R.C. on Nov. 30, 2012, the entire contents of which are hereby incorporated by reference. 
       BACKGROUND OF THE DISCLOSURE 
       [0002]    1. Technical Field of the Disclosure 
         [0003]    The disclosure relates to a printed circuit board (PCB), and more particularly to a PCB capable of performing wireless transmission and a server using the same. 
         [0004]    2. Description of the Related Art 
         [0005]    In the manufacturing of a PCB, circuit layout is generally performed first to generate an electronic file of a layout chart. That is, a layout engineer places electronic components at predetermined positions on the PCB, connects the electronic components with wires to complete the design of the layout chart, and proceed to Gerber out according to the electronic file of the layout chart to generate a mask picture. Finally, the PCB manufacturer manufactures the PCB through the mask picture. 
         [0006]      FIG. 1  is a block diagram of an ordinary PCB. To implement a signal transmission and related operations between the components, the layout engineer needs to perform wiring of components  110 ,  120 ,  130 ,  140  on the PCB  100  by using wires, so as to connect the components  110 ,  120 ,  130 ,  140 . In the layout of the PCB  100 , since the distances between the components  110 ,  120 ,  130 ,  140  are not the same, the layout engineer needs to set the wires of the same length between the components  110 ,  120 ,  130 ,  140 , to achieve a time sequence synchronization of signals. Additionally, since diversified components are disposed on the PCB  100  and the space is limited, when the component  110  needs to be moved, the layout engineer needs to modify the length of the wires, which takes more time for modification. 
         [0007]    The above layout manner may increase the design complexity of the layout, prolong the layout time, lower the layout efficiency, and waste the utilization space of the PCB. Therefore, the design of the PCB needs to be improved. 
       SUMMARY OF THE DISCLOSURE 
       [0008]    In an embodiment, the disclosure provides a printed circuit board (PCB) comprising a plurality of receiving components and a sending component. Each of the receiving components comprises a receiving unit and a first control unit. The receiving unit is configured for receiving a radio signal. The first control unit is coupled to the receiving unit and is configured with a first comparison table storing related information of the receiving component. The first control unit is configured for decoding the radio signal according to the first comparison table, so as to obtain a corresponding control signal. The sending component comprises a sending unit and a second control unit. The sending unit is configured for sending the radio signals. The second control unit is coupled to the sending unit and is configured with a second comparison table storing the related information of the receiving components. When the sending component outputs the control signals through the second control unit, the second control unit generates the control signals according to the related information of the receiving components, and encodes the control signals to generate the radio signals.

     DETAILED DESCRIPTION 
       [0015]    In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosed embodiments. It will be apparent, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are schematically shown in order to simplify the drawing. 
         [0016]    In the following embodiments, the same or similar components are marked by the same symbols. 
         [0017]      FIG. 2A  is a block diagram of a PCB of the disclosure. The PCB  200  in this embodiment is a mainboard of a server. The PCB  200  comprises receiving components  210 ,  220 ,  230  and a sending component  240 . 
         [0018]    For ease of description, three receiving components (that is, the receiving components  210 ,  220 ,  230 ) are used in this embodiment as an example for illustration, but the disclosure is not limited thereto. Moreover, the user may adjust the number of the receiving components to be three or more upon requirements. The receiving components  210 ,  220 ,  230  are, for example, central processing units (CPUs), hard disks or other circuit components, such as resistors, inductors or capacitors. 
         [0019]    The receiving components  210 ,  220 ,  230  respectively have receiving units  211 ,  221 ,  231  and first control units  212 ,  222 ,  232 . The receiving units  211 ,  221 ,  231  are used for receiving radio signals. 
         [0020]    The first control units  212 ,  222 ,  232  are coupled to the receiving units  211 ,  221 ,  231 , and are respectively configured with a first comparison table, the first comparison tables respectively storing related information of the receiving components  210 ,  220 ,  230 . The first control units  212 ,  222 ,  232  receive the radio signals, and decode the radio signals according to the related information of the receiving components  210 ,  220 ,  230  in the first comparison tables, to obtain corresponding control signals and proceed to perform related operations. 
         [0021]    The sending component  240  comprises a sending unit  241  and a second control unit  242 . The sending unit  241  is used for sending the radio signals. The second control unit  242  is coupled to the sending unit  241  and configured with a second comparison table storing the related information of the receiving components  210 ,  220 ,  230 . When the sending component  240  is used for outputting the control signals through the second control unit  242 , the second control unit  242  generates the corresponding control signals according to the related information of the receiving components  210 ,  220 ,  230 . The second control unit  242  further encodes the control signals to generate the corresponding radio signals to be sent by the sending unit  241 . 
         [0022]    In this embodiment, the related information of the receiving components  210 ,  220 ,  230  comprises names and part numbers of the receiving components  210 ,  220 ,  230 . The first comparison table of the first control unit  212  stores the name and the part number of the receiving component  210 . The first comparison table of the first control unit  222  stores the name and the part number of the receiving component  220 . The first comparison table of the first control unit  232  stores the name and the part number of the receiving component  230 . The second comparison table of the second control unit  242  stores the names and the part numbers of the receiving components  210 ,  220 ,  230 . 
         [0023]    Since the second control unit  242  is capable of acquiring the corresponding part numbers and names of the receiving components  210 ,  220 ,  230  by looking up the second comparison table, the second control unit  242  generates the control signals, adds the names and the part numbers of the receiving components  210 ,  220 ,  230  into the corresponding control signals, and encodes the control signals into the radio signals to be sent by the sending unit  241  to the receiving components  210 ,  220 ,  230 . 
         [0024]    For example, assume that the name of the receiving component  210  is “resistor” and the part number thereof is “R 1 ”, the name of the receiving component  220  is “inductor” and the part number thereof is “L 2 ”, and the name of the receiving component  230  is “CPU” and the part number thereof is “CPU 3 ”. The second control unit  242 , for example, adds the serial number of “resistor_R 1 ” into the control signal to be transmitted to the receiving component  210 , the second control unit  242 , for example, adds the serial number of “inductor_L 2 ” into the control signal to be transmitted to the receiving component  220 , and the second control unit  242 , for example, adds the serial number of “CPU_CPU 3 ” into the control signal to be transmitted to the receiving component  230 . 
         [0025]    When the receiving component  210  receives the radio signal having the serial number of “resistor_R 1 ” through the receiving unit  211 , the first control unit  212  decodes the radio signal having the serial number of “resistor_R 1 ”, to obtain the control signal having the serial number of “resistor_R 1 ”. The first control unit  212 , subsequently is configured for confirming that the serial number of “resistor_R 1 ” is consistent with the related information (that is, the name and the part number) of the receiving component  210  that is stored in the first comparison table, by looking up the first comparison table, so as to determine that the control signal is transmitted to the receiving component  210 . Therefore, the receiving component  210  performs related operations according to the control signal. 
         [0026]    When the receiving component  210  receives the radio signal having the serial number of “inductor_L 2 ” through the receiving unit  211 , the first control unit  212  decodes the radio signal having the serial number of “inductor_L 2 ”, to obtain the control signal having the serial number of “inductor_L 2 ”. The first control unit  212 , subsequently, is configured for confirming that the serial number of “inductor_L 2 ” is inconsistent with the related information (that is, the name and the part number) of the receiving component  210  that is stored in the first comparison table, by looking up the first comparison table, so as to determine that the control signal is not transmitted to the receiving component  210 . Therefore, the receiving component  210  does not perform related operations. 
         [0027]    When the receiving component  210  receives the radio signal having the serial number of “CPU_CPU 3 ” through the receiving unit  211 , the first control unit  212  decodes the radio signal having the serial number of “CPU_CPU 3 ”, to obtain the control signal having the serial number of “CPU_CPU 3 ”. Then, the first control unit  212  is configured for confirming that the serial number of “CPU_CPU 3 ” is inconsistent with the related information (that is, the name and the part number) of the receiving component  210  that is stored in the first comparison table, by looking up the first comparison table, so as to determine that the control signal is not transmitted to the receiving component  210 . Therefore, the receiving component  210  does not perform related operations. 
         [0028]    Reference can be made to the implementation and description of the receiving component  210  for the related operations of the receiving components  220 ,  230 , and the details are not repeated herein. The receiving components  210 ,  220 ,  230  respectively decode the received radio signals to obtain the control signals transmitted thereto, so as to perform related operations. Therefore, signal transmission errors can be avoided, and the wiring between the sending component  240  and the receiving components  210 ,  220 ,  230  is saved, so that the design and layout complexity of the PCB  200  is reduced. 
         [0029]    In an embodiment, assume that the receiving components  220  and  230  are of the same type. For instance, the names of the receiving components  220  and  230  are “resistor” and the part numbers thereof are respectively “R 1 ” and “R 2 ”. The second control unit  242 , for example, adds the serial numbers of “resistor_R 1 ” and “resistor_R 2 ” into the control signals to be transmitted to the receiving components  220  and  230 , encodes the two control signals into two corresponding radio signals, and sets the radio signals into a group of radio signals to be sent by the sending unit  241 . Therefore, the sending unit  241  is capable of sending the control signals to the receiving components  220  and  230  at the same time, to achieve time sequence control of time synchronization of the signals. 
         [0030]      FIG. 2B  is another block diagram of a PCB of the disclosure. The PCB  201  in this embodiment is different from the PCB  200  in  FIG. 2A  in that, in addition to the receiving units  211 ,  221 ,  231  and the first control units  212 ,  222 ,  232 , the receiving components  210 ,  220 ,  230  of the PCB  201  further comprises subsidiary receiving components  213 ,  214 ,  223 ,  224 ,  233 ,  234 . 
         [0031]    The first control units  212 ,  222 ,  232  respectively store related information of the subsidiary receiving components  213 ,  214 ,  223 ,  224 ,  233 ,  234 . The related information of the subsidiary receiving components  213 ,  214 ,  223 ,  224 ,  233 ,  234 , for example, comprises names and part numbers of the subsidiary receiving components  213 ,  214 ,  223 ,  224 ,  233 ,  234 . 
         [0032]    The second comparison table of the second control unit  242  further stores the related information of the subsidiary receiving components  213 ,  214 ,  223 ,  224 ,  233 ,  234 . When the sending component  240  is used for outputting the control signals through the second control unit  242 , the second control unit  242  generates the control signals according to the related information of the receiving components  210 ,  220 ,  230  and the related information of the subsidiary receiving components  213 ,  214 ,  223 ,  224 ,  233 ,  234 . 
         [0033]    Then, the second control unit  242  further sets the control signals corresponding to the subsidiary receiving components  213 ,  214 ,  223 ,  224 ,  233 ,  234  of the receiving components  210 ,  220 ,  230  into a group of signals respectively, and encodes the groups of signals to generate the corresponding radio signals to be sent by the sending unit  241  to the first control units  212 ,  222 ,  232  of the receiving components  210 ,  220 ,  230 . 
         [0034]    The first control units  212 ,  222 ,  232  decode the radio signals having the groups of signals according to the related information of the subsidiary receiving components  213 ,  214 ,  223 ,  224 ,  233 ,  234 , to obtain the control signals corresponding to the subsidiary receiving components  213 ,  214 ,  223 ,  224 ,  233 ,  234 . Thereby, the subsidiary receiving components  213 ,  214 ,  223 ,  224 ,  233 ,  234  may perform related operations according to the corresponding control signals. 
         [0035]    For example, assume that the name of the receiving component  210  is “functional component (FC)” and the part number thereof is “FC 1 ”, the name of the subsidiary receiving component  213  is “resistor” and the part number thereof is “R 2 ”, and the name of the subsidiary receiving component  214  is “baseboard management controller (BMC)” and the part number thereof is “BMC 1 ”. The second control unit  242 , for example, adds the serial numbers of “FC_FC 1 ” and “resistor R 2 ” as well as “FC_FC 1 ” and “BMC_BMC 1 ” into the control signals to be transmitted to the subsidiary receiving components  213 ,  214  of the receiving component  210  respectively. 
         [0036]    The second control unit further sets the control signals to be transmitted to the subsidiary receiving components  213 ,  214  into a group of signals, and encodes the group of signals into the radio signals to be sent by the sending unit  241 . The group of signals comprises the serial numbers of “FC_FC 1 ” and “resistor_R 2 ” as well as “FC_FC 1 ” and “BMC_BMC 1 ”. 
         [0037]    When the receiving component  210  receives the radio signals having the serial numbers of “FC_FC 1 ” and “resistor_R 2 ” as well as “FC_FC 1 ” and “BMC_BMC 1 ” through the receiving unit  211 , the first control unit  212  decodes the radio signals having the serial numbers of “FC_FC 1 ” and “resistor_R 2 ” as well as “FC_FC 1 ” and “BMC_BMC 1 ”, to obtain the control signals having the serial numbers of “FC_FC 1 ” and “resistor_R 2 ” as well as “FC_FC 1 ” and “BMC_BMC 1 ”. 
         [0038]    The first control unit  212  is configured for confirming that the serial numbers of “FC_FC 1 ” and “resistor_R 2 ” as well as “FC_FC 1 ” and “BMC_BMC 1 ” are consistent with the related information (that is, the names and the part numbers) of the receiving component  210  and the subsidiary receiving components  213 ,  214  that is stored in the first comparison table, by looking up the first comparison table, so as to determine that the control signals are transmitted to the receiving component  210 . The first control unit  212  transmits the corresponding “resistor_R 2 ” and “BMC_BMC 1 ” respectively to the subsidiary receiving components  213 ,  214 , so that the subsidiary receiving components  213 ,  214  perform related operations accordingly. 
         [0039]    When the first control unit  212  confirms, through comparison, that the decoded control signals are inconsistent with the related information (that is, the name and the part number) of the receiving component  210  that is stored in the first comparison table, it is determined that the control signals are not transmitted to the receiving component  210 . Therefore, the receiving component  210  and the subsidiary receiving components  213 ,  214  do not perform related operations. 
         [0040]    Reference can be made to the implementation and description of the receiving component  210  and the subsidiary receiving components  213 ,  214  for the related operations of the receiving components  220 ,  230  and the subsidiary receiving components  223 ,  224 ,  233 ,  234 , and the details are not repeated herein. The receiving components  210 ,  220 ,  230  and the subsidiary receiving components  213 ,  214 ,  223 ,  224 ,  233 ,  234  respectively decode the received radio signals to obtain the control signals transmitted thereto, so as to perform related operations. 
         [0041]    Therefore, signal transmission errors can be avoided, and the wiring between the sending component  240  and the receiving components  210 ,  220 ,  230  is saved, so that the design and layout complexity of the PCB  201  is reduced. Further, the control signals to be sent to the subsidiary receiving components of the same receiving component are set into a group of signals, so as to be sent to the receiving component at the same time. Therefore, the subsidiary receiving components are capable of receiving the control signals at the same time and performing related operations accordingly, to achieve time sequence control of time synchronization of the signals. 
         [0042]      FIG. 3A  is a block diagram of a server of the disclosure. The server  300  comprises PCBs  302  and  304 . In this embodiment, the PCBs  302  and  304  in this embodiment are mainboards or riser cards of the server  300 . 
         [0043]    For ease of description, two PCBs (that is, the PCBs  302  and  304 ) are used in this embodiment as an example for illustration, but the disclosure is not limited thereto. Therefore, the user may adjust the number of the PCBs to be two or more upon requirements. 
         [0044]    In this embodiment, the PCB  302  comprises receiving components  310 ,  320 ,  330  and a sending component  340 . The receiving components  310 ,  320 ,  330  respectively comprise receiving units  311 ,  321 ,  331  and first control units  312 ,  322 ,  332 . The sending component  340  comprises a sending unit  341  and a second control unit  342 . 
         [0045]    The PCB  304  comprises receiving components  350 ,  360 ,  370  and a sending component  380 . The receiving components  350 ,  360 ,  370  respectively comprise receiving units  351 ,  361 ,  371  and first control units  352 ,  362 ,  372 . The sending component  380  comprises a sending unit  381  and a second control unit  382 . Reference can be made to the implementation of the PCB  200  in  FIG. 2A  for the internal components and implementation of the PCBs  302  and  304 , and the details are not repeated herein. 
         [0046]    The PCBs  302  and  304  in this embodiment are different from the PCB  200  in  FIG. 2A  in that, in addition to the related information of all the receiving components  310 ,  320 ,  330 ,  350 ,  360 ,  370 , the second comparison tables in the second control units  342  and  382  of the PCBs  302  and  304  further store the related information of the PCBs  302  and  304 . 
         [0047]    Therefore, when the sending components  340 ,  380  are used for outputting the control signals through the second control units  342 ,  382 , the second control units  342 ,  382  generate the corresponding control signals according to the related information of the receiving components  310 ,  320 ,  330 ,  350 ,  360 ,  370  and the related information of the PCBs  302 ,  304 , and further encode the control signals to generate the corresponding radio signals to be sent by the sending units  341 ,  381 . 
         [0048]    In addition to the related information of the receiving components  310 ,  320 ,  330 ,  350 ,  360 ,  370 , the first comparison tables in the first control units  312 ,  322 ,  332 ,  352 ,  362 ,  372  of the PCBs  302  and  304  further store the related information of the PCBs  302 ,  304 . That is, the first comparison table in the first control unit  312  stores the related information of the receiving component  310  and the related information of the corresponding PCB  302 . The implementation of the remaining first control units  322 ,  332 ,  352 ,  362 ,  372  can be deduced by analogy. 
         [0049]    In this embodiment, the related information of the receiving components  310 ,  320 ,  330 ,  350 ,  360 ,  370  comprises the names and the part numbers of the receiving components  310 ,  320 ,  330 ,  350 ,  360 ,  370 . The first comparison tables in the first control units  312 ,  322 ,  332 ,  352 ,  362 ,  372  of the receiving components  310 ,  320 ,  330 ,  350 ,  360 ,  370  respectively store the names and the part numbers of the receiving components  310 ,  320 ,  330 ,  350 ,  360 ,  370 . 
         [0050]    The related information of the PCBs  302  and  304 , for example, comprises the names and the part numbers of the PCBs  302  and  304 . The second comparison tables in the second control units  342  and  382  respectively store the names and the part numbers of the receiving components  310 ,  320 ,  330 ,  350 ,  360 ,  370  and the names and the part numbers of the PCBs  302  and  304 . 
         [0051]    The second control units  342  and  382  acquire, by looking up the second comparison tables, the corresponding part numbers and names of the receiving components  310 ,  320 ,  330 ,  350 ,  360 ,  370  and the PCBs  302 ,  304 , so that the second control units  342  and  382  generate the control signals, add the names and the part numbers of the receiving components  310 ,  320 ,  330 ,  350 ,  360 ,  370  and the PCBs  302 ,  304  into the corresponding control signals, and encode the control signals into the radio signals to be sent by the sending units  341  and  381  to the receiving components  310 ,  320 ,  330 ,  350 ,  360 ,  370 . 
         [0052]    For example, assume that the name of the receiving component  310  is “resistor” and the part number thereof is “R 1 ”, the name of the receiving component  320  is “inductor” and the part number thereof is “L 2 ”, the name of the receiving component  330  is “CPU” and the part number thereof is “CPU 3 ”, the name of the receiving component  350  is “resistor” and the part number thereof is “R 2 ”, the name of the receiving component  360  is “inductor” and the part number thereof is “L 4 ”, the name of the receiving component  370  is “capacitor” and the part number thereof is “C 3 ”, the name of the PCB  302  is “PCB 1 ” and the part number thereof is “ 001 ”, and the name of the PCB  304  is “PCB 2 ” and the part number thereof is “ 003 ”. 
         [0053]    The second control unit  342 , for example, adds the serial numbers of “resistor_R 1 ” and “PCB 1 _ 001 ” into the control signal to be transmitted to the receiving component  310 , the second control unit  342 , for example, adds the serial numbers of “inductor_L 2 ” and “PCB 1 _ 001 ” into the control signal to be transmitted to the receiving component  320 , the second control unit  342 , for example, adds the serial numbers of “CPU_CPU 3 ” and “PCB 1 _ 001 ” into the control signal to be transmitted to the receiving component  330 , the second control unit  342 , for example, adds the serial numbers of “resistor_R 2 ” and “PCB 2 _ 003 ” into the control signal to be transmitted to the receiving component  350 , the second control unit  342 , for example, adds the serial numbers of “inductor_L 4 ” and “PCB 2 _ 003 ” into the control signal to be transmitted to the receiving component  360 , and the second control unit  342 , for example, adds the serial numbers of “capacitor_C 3 ” and “PCB 2 _ 003 ” into the control signal to be transmitted to the receiving component  370 . The implementation of the second control unit  382  can be deduced by analogy, and the details are not repeated herein. 
         [0054]    When the receiving component  310  receives the radio signal having the serial numbers of “resistor_R 1 ” and “PCB 1 _ 001 ” through the receiving unit  311 , the first control unit  312  decodes the radio signal having the serial numbers of “resistor_R 1 ” and “PCB 1 _ 001 ”, to obtain the control signal having the serial numbers of “resistor_R 1 ” and “PCB 1 _ 001 ”. Then, The first control unit  312  is configured for confirming that the serial numbers of “resistor_R 1 ” and “PCB 1 _ 001 ” are consistent with the related information (that is, the name and the part number) of the receiving component  310  that is stored in the first comparison table, by looking up the first comparison table, so as to determine that the control signal is transmitted to the receiving component  310 . Therefore, the receiving component  310  performs related operations according to the control signal. 
         [0055]    When the receiving component  310  receives the radio signal having the serial numbers of “inductor_L 2 ” and “PCB 1 _ 001 ” through the receiving unit  311 , the first control unit  312  decodes the radio signal having the serial numbers of “inductor_L 2 ” and “PCB 1 _ 001 ”, to obtain the control signal having the serial numbers of “inductor_L 2 ” and “PCB 1 _ 001 ”. Then, the first control unit  312 is configured for confirming that the serial numbers of “inductor_L 2 ” and “PCB 1 _ 001 ” are inconsistent with the related information (that is, the name and the part number) of the receiving component  310  that is stored in the first comparison table, by looking up the first comparison table, so as to determine that the control signal is not transmitted to the receiving component  310 . Therefore, the receiving component  310  does not perform related operations. 
         [0056]    When the receiving component  310  receives the radio signal having the serial numbers of “CPU_CPU 3 ” and “PCB 1 _ 001 ” through the receiving unit  311 , the first control unit  212  decodes the radio signal having the serial numbers of “CPU_CPU 3 ” and “PCB 1 _ 001 ”, to obtain the control signal having the serial numbers of “CPU_CPU 3 ” and “PCB 1 _ 001 ”, and is configured for confirming that the serial numbers of “CPU_CPU 3 ” and “PCB 1 _ 001 ” are inconsistent with the related information (that is, the name and the part number) of the receiving component  310  that is stored in the first comparison table, by looking up the first comparison table, so as to determine that the control signal is not transmitted to the receiving component  310 . Therefore, the receiving component  310  does not perform related operations. 
         [0057]    When the receiving component  310  receives the radio signal having the serial numbers of “resistor_R 2 ” and “PCB 2 _ 003 ” through the receiving unit  311 , the first control unit  212  decodes the radio signal having the serial numbers of “resistor_R 2 ” and “PCB 2 _ 003 ”, to obtain the control signal having the serial numbers of “resistor_R 2 ” and “PCB 2 _ 003 ”, and is configured for confirming that the serial numbers of “resistor_R 2 ” and “PCB 2 _ 003 ” are inconsistent with the related information (that is, the name and the part number) of the receiving component  310  that is stored in the first comparison table, by looking up the first comparison table, so as to determine that the control signal is not transmitted to the receiving component  310 . Therefore, the receiving component  310  does not perform related operations. The rest can be deduced by analogy. 
         [0058]    Reference can be made to the implementation and description of the receiving component  310  for the related operations of the receiving components  320 ,  330 ,  350 ,  360 ,  370 , and the details are not repeated herein. The receiving components  320 ,  330 ,  350 ,  360 ,  370  are configured for respectively decoding the received radio signals to obtain the control signals transmitted thereto, so as to perform related operations. Therefore, signal transmission errors can be avoided, and the wiring between the sending components  340 ,  380  and the receiving components  310 ,  320 ,  330 ,  350 ,  360 ,  370  is saved. Thereby, the design and layout complexity of the PCBs  302 ,  304  in the server  300  is reduced. 
         [0059]    In an embodiment, assume that the receiving components  320  and  330  are of the same type. For example, the names of the receiving components  320  and  330  are “resistor” and the part numbers thereof are respectively “R 1 ” and “R 2 ”. The second control unit  342 , for example, adds the serial numbers of “resistor_R 1 ” and “resistor_R 2 ” into the control signals to be transmitted to the receiving components  320  and  330 , encodes the two control signals into two corresponding radio signals, and sets the radio signals into a group of radio signals to be sent by the sending unit  341 . Therefore, the sending unit  341  is capable of sending the control signals to the receiving components  320  and  330  at the same time, to achieve time sequence control of time synchronization of the signals. 
         [0060]      FIG. 3B  is another block diagram of a server of the disclosure. The PCBs  303  and  305  of the server  301  in this embodiment are different from the PCBs  302 ,  304  in  FIG. 3A  in that, in addition to the receiving units  311 ,  321 ,  331 ,  351 ,  361 ,  371  and the first control units  312 ,  322 ,  332 ,  352 ,  362 ,  372 , the receiving components  310 ,  320 ,  330 ,  350 ,  360 ,  370  of the PCBs  302 ,  304  further comprise subsidiary receiving components  313 ,  314 ,  323 ,  324 ,  333 ,  334 ,  353 ,  354 ,  363 ,  364 ,  373 ,  374 . 
         [0061]    The first control units  312 ,  322 ,  332 ,  352 ,  362 ,  372  respectively store related information of the subsidiary receiving components  313 ,  314 ,  323 ,  324 ,  333 ,  334 ,  353 ,  354 ,  363 ,  364 ,  373 ,  374 .

         [0062]    The second comparison tables in the second control units  342  and  382  further store the related information of the subsidiary receiving components  313 ,  314 ,  323 ,  324 ,  333 ,  334 ,  353 ,  354 ,  363 ,  364 ,  373 ,  374 . When the sending components  340  and  380  are used for outputting the control signals through the second control units  342  and  382 , the second control units  342  and  382  generate the control signals according to the related information of the receiving components  310 ,  320 ,  330 ,  350 ,  360 ,  370  and the related information of the subsidiary receiving components  313 ,  314 ,  323 ,  324 ,  333 ,  334 ,  353 ,  354 ,  363 ,  364 ,  373 ,  374 . 
         [0063]    The second control units  342  and  382  further set the control signals corresponding to the subsidiary receiving components  313 ,  314 ,  323 ,  324 ,  333 ,  334 ,  353 ,  354 ,  363 ,  364 ,  373 ,  374  of the receiving components  310 ,  320 ,  330 ,  350 ,  360 ,  370  into a group of signals respectively, and encode the groups of signals to generate the corresponding radio signals to be sent by the sending units  341  and  381  to the first control units  311 ,  321 ,  331 ,  351 ,  361 ,  371  of the receiving components  310 ,  320 ,  330 ,  350 ,  360 ,  370 . 
         [0064]    Then, the first control units  311 ,  321 ,  331 ,  351 ,  361 ,  371  decode the radio signals having the groups of signals according to the related information of the subsidiary receiving components  313 ,  314 ,  323 ,  324 ,  333 ,  334 ,  353 ,  354 ,  363 ,  364 ,  373 ,  374 , to obtain the control signals corresponding to the subsidiary receiving components  313 ,  314 ,  323 ,  324 ,  333 ,  334 ,  353 ,  354 ,  363 ,  364 ,  373 ,  374 . Thereby, the subsidiary receiving components  313 ,  314 ,  323 ,  324 ,  333 ,  334 ,  353 ,  354 ,  363 ,  364 ,  373 ,  374  may perform related operations according to the corresponding control signals. 
         [0065]    Reference can be made to the implementation of the PCB  201  in  FIG. 2B  for the implementation of the PCBs  302 ,  304 , and the details are not repeated herein. Therefore, this embodiment is able to reduce the design and layout complexity of the PCBs  302 ,  304 , to achieve time sequence control of time sequence synchronization of the signals. 
         [0066]    According to the PCB and the server using the same provided by the embodiments of the disclosure, the sending component is configured with the sending unit and the receiving components are configured with the receiving units, and the second control unit generates the control signals to be output to the receiving components according to the related information of the receiving components, encodes the control signals to generate the radio signals, and transmits the radio signals to the receiving units in a wireless manner. The receiving units decode the radio signals, and the first control units of the receiving units obtain the corresponding control signals according to the related information of the receiving components, so as to perform related operations. 
         [0067]    In addition to the related information of the receiving components, the second control unit may also generate the corresponding control signals according to the related information of the PCBs. Thereby, false actions of the receiving components on different PCBs can be prevented. When the receiving components are of the same type, the second control unit encodes the control signals into the radio signals, and sets the radio signals into a group of radio signals to be sent by the sending unit. Furthermore, the control signals to be sent to the subsidiary receiving components of the same receiving component are set into a group of signals, so that the subsidiary receiving components are capable of receiving the control signals at the same time and performing related operations accordingly. Therefore, the design complexity of the layout is effectively reduced, the layout efficiency and utilization space of the PCB are improved, and time sequence control of time synchronization of the signals is achieved.
