The technical scheme of the invention will be further described with reference to the examples and the accompanying drawings.

Referring to fig. 1 to 3, the present application discloses a circuit board circuit detection system 100, which includes a circuit board 10, a second rf circuit 11, and a second ground circuit 12 spaced apart from the second rf circuit 11, where the rf circuit may include a first rf circuit 101 spaced apart from the second rf circuit, a first ground circuit 102, and an electronic device 103 connected to the first rf circuit 101, where the first ground circuit 102 is configured to enable transmission of an rf signal along the first rf circuit 101, and the electronic device 103 is configured to receive the rf signal sent by the first rf circuit 101. The second rf circuit 11 is provided with a first conductive portion 111 and a second conductive portion 112, the first conductive portion 111 and the second conductive portion 112 are both used for electrically connecting with the first rf circuit 101, the second ground circuit 12 is provided with a third conductive portion 121 and a fourth conductive portion 122, and the third conductive portion 121 and the fourth conductive portion 122 are both used for electrically connecting with the first ground circuit 102.

The circuit board line detection system 100 provided by the application enables the second radio frequency line 11 to transmit radio frequency signals by electrically connecting the first conductive part 111 and the second conductive part 112 arranged on the second radio frequency line 11 with two ends of the detection area of the first radio frequency line 101 and electrically connecting the third conductive part 121 and the fourth conductive part 122 arranged on the second grounding line 12 with two ends of the detection area of the first grounding line 102. When the detection area has a circuit breaking problem, the second radio frequency circuit 11 can connect the first radio frequency circuits 101 at two ends of the circuit breaking position, so that the radio frequency signal can be continuously transmitted to the electronic device 103 on the first radio frequency channel, and the electronic device 103 can be normally used at this time. That is, when the first rf circuit 101 or the first ground circuit 102 has a disconnection problem, the first conductive part 111 and the second conductive part 112 on the second rf circuit 11 of the circuit board circuit detection system 100 are connected to two ends of the detection area of the first rf circuit 101, and the third conductive part 121 and the fourth conductive part 122 on the second ground circuit 12 are connected to two ends of the detection area of the first ground circuit 102. Thus, when the detection area has a circuit breaking problem, the radio frequency signal on the first radio frequency circuit 101 can be transmitted to the second radio frequency circuit 11 from one end of the circuit breaking position, and then transmitted back to the other end of the circuit breaking position through the second radio frequency circuit 11 to be conveyed back to the first radio frequency circuit 101 again, so that the electronic device 103 can receive the radio frequency signal on the first radio frequency circuit 101, and the electronic device 103 can be used normally. In addition, after detecting the open circuit position on the first rf circuit 101 or the first ground circuit 102, the circuit board circuit detection system 100 may be electrically connected to the open circuit position, that is, two ends of the open circuit position are electrically connected to the second ground circuit 12 through the second rf circuit 11, so as to achieve the purpose of repairing the first rf circuit 101 or the first ground circuit 102. In addition, since the circuit board line detection system 100 provided by the application can detect and repair the first radio frequency line 101 or the first grounding line 102, the first radio frequency line 101 or the first grounding line 102 with faults and the electronic device 103 connected with the first radio frequency line or the first grounding line 102 are not required to be replaced, which is beneficial to reducing the production cost of the circuit board 10.

Alternatively, the electronic device 103 may be a light bulb or an alarm, or the like. Illustratively, when the electronic device 103 is a light bulb, the light bulb cannot be turned on if there is a disconnection problem of the first radio frequency line 101 connected to the electronic device 103; if the first conductive part 111 and the second conductive part 112 of the second rf circuit 11 are electrically connected to two ends of the open circuit position of the first rf circuit 101, respectively, when the third conductive part 121 and the fourth conductive part 122 of the second ground circuit 12 are electrically connected to two ends of the open circuit position of the first ground circuit 102, respectively, the rf signal on the first rf circuit 101 can be transmitted to the lamp bead through the second rf circuit 11, and the lamp bead can be turned on.

It should be noted that, three conditions exist in the open state of the rf circuit, the first is that the first rf circuit 101 has an open problem, and the first ground circuit 102 is normal, at this time, the rf circuit cannot realize the function of transmitting the rf signal, at this time, the electronic device 103 cannot work, for example, the lamp bead cannot be turned on; the second is that the first rf circuit 101 and the first ground circuit 102 have a circuit breaking problem, at this time, the rf circuit cannot realize the function of transmitting rf signals, at this time, the electronic device 103 cannot work, for example, the lamp bead cannot be turned on; the third type of the first rf circuit 101 is normal, and the first ground circuit 102 has a disconnection problem, so that the rf circuit has poor rf signal transmission effect, and the electronic device 103 cannot work or cannot work normally, for example, the lamp bead cannot be turned on or the brightness of the lamp bead cannot reach the expected brightness.

The specific structure of the circuit board line detection system 100 will be described in detail below taking the case where the first rf line 101 is broken and the first ground line 102 is normal as an example. I.e. the first rf line 101 has a break 1011 (see in particular fig. 2).

In some embodiments, to ensure that the transmission effect of the rf signal on the first rf line 101 and the second rf line 11 is the same, the impedance of the second rf line 11 needs to be equal to the impedance of the first rf line 101. In this way, the transmission effect of the radio frequency signals on the first radio frequency circuit 101 and the second radio frequency circuit 11 is the same, so that the accuracy of detecting the open circuit position of the radio frequency circuit by the circuit board circuit detection system 100 can be improved, and the repaired radio frequency circuit is ensured not to influence the transmission of the radio frequency signals.

Alternatively, the first conductive portion 111, the second conductive portion 112, the third conductive portion 121, and the fourth conductive portion 122 may be conductive materials such as probes or wires, and may be specifically determined according to practical situations.

As an alternative embodiment, the first conductive part 111 and/or the second conductive part 112 may be slidably disposed on the second radio frequency circuit 11, and/or the third conductive part 121 and/or the fourth conductive part 122 may be slidably disposed on the second ground circuit 12. I.e. the following is present: first, the first conductive part 111 is slidably disposed on the second rf circuit 11, and the third conductive part 121 is slidably disposed on the second ground circuit 12; second, the first conductive portion 111 is slidably disposed on the second rf circuit 11, and the fourth conductive portion 122 is slidably disposed on the second ground circuit 12; third, the first conductive portion 111 is slidably disposed on the second rf circuit 11, and the third conductive portion 121 and the fourth conductive portion 122 are both slidably disposed on the second ground circuit 12; fourth, the second conductive portion 112 is slidably disposed on the second rf circuit 11, and the third conductive portion 121 is slidably disposed on the second ground circuit 12; fifth, the second conductive portion 112 is slidably disposed on the second rf circuit 11, and the fourth conductive portion 122 is slidably disposed on the second ground circuit 12; sixth, the second conductive portion 112 is slidably disposed on the second rf circuit 11, and the third conductive portion 121 and the fourth conductive portion 122 are both slidably disposed on the second ground circuit 12; seventh, the first conductive portion 111 and the second conductive portion 112 are both slidably disposed on the second rf circuit 11, and the third conductive portion 121 is slidably disposed on the second ground circuit 12; eighth, the first conductive portion 111 and the second conductive portion 112 are both slidably disposed on the second rf circuit 11, and the fourth conductive portion 122 is slidably disposed on the second ground circuit 12; ninth, the first conductive portion 111 and the second conductive portion 112 are both slidably disposed on the second rf circuit 11, and the third conductive portion 121 and the fourth conductive portion 122 are both slidably disposed on the second ground circuit 12. This arrangement can facilitate adjustment of the length of the second radio frequency line 11 between the first conductive portion 111 and the second conductive portion 112, and adjustment of the length of the second ground line 12 between the third conductive portion 121 and the fourth conductive portion 122, so that the length of the second radio frequency line 11 between the first conductive portion 111 and the second conductive portion 112 and the length of the second ground line 12 between the third conductive portion 121 and the fourth conductive portion 122 can be adapted to the size of the break 1011, so that the first conductive portion 111 and the second conductive portion 112 can be connected to the first radio frequency line 101, and the third conductive portion 121 and the fourth conductive portion 122 can be connected to the first ground line 102.

In this embodiment, when the first conductive portion 111 is slidably disposed on the second rf circuit 11 and the third conductive portion 121 is slidably disposed on the second ground circuit 12, the circuit board circuit detection system 100 further includes a first connecting component 13, and the first connecting component 13 is connected to the first conductive portion 111 and the third conductive portion 121. Thus, the first connecting member 13 can be slid by the inspector to simultaneously slide the first conductive portion 111 and the second conductive portion 112, which is advantageous for simplifying the inspection steps of the inspector.

When the second conductive portion 112 is slidably disposed on the second rf circuit 11 and the fourth conductive portion 122 is slidably disposed on the second ground circuit 12, the circuit board trace detection system 100 further includes a second connection member 14, and the second connection member 14 is connected to the second conductive portion 112 and the fourth conductive portion 122. Thus, the detection personnel can slide the second connecting member 14 to simultaneously slide the second conductive portion 112 and the fourth conductive portion 122, which is beneficial to simplifying the detection steps of the detection personnel.

As another alternative embodiment, the circuit board line inspection system 100 further includes a first conductive connector 15, a second conductive connector 16, a third conductive connector 17, and a fourth conductive connector 18. The first conductive connecting piece 15 and/or the second conductive connecting piece 16 are slidably disposed on the second radio frequency circuit 11, and the first conductive portion 111 is disposed on the first conductive connecting piece 15 and electrically connected to the second radio frequency circuit 11 through the first conductive connecting piece 15, and the second conductive portion 112 is disposed on the second conductive connecting piece 16 and electrically connected to the second radio frequency circuit 11 through the second conductive connecting piece 16, that is, the first conductive connecting piece 15 is slidably disposed on the second radio frequency circuit 11, or the second conductive connecting piece 16 is slidably disposed on the second radio frequency circuit 11, or both the first conductive connecting piece 15 and the second conductive connecting piece 16 are slidably disposed on the second radio frequency circuit 11. Thus, the inspector can slide the first conductive connecting piece 15 and/or the second conductive connecting piece 16 according to the size of the break 1011 of the radio frequency circuit, that is, slide the first conductive connecting piece 15, or slide the second conductive connecting piece 16, or slide the first conductive connecting piece 15 and the second conductive connecting piece 16 at the same time, so as to adjust the length of the second radio frequency circuit 11 between the first conductive connecting piece 15 and the second conductive connecting piece 16, so that the first conductive part 111 on the first conductive connecting piece 15 and the second conductive part 112 on the second conductive connecting piece 16 can be connected to the first radio frequency circuit 101 at two ends of the break 1011.

Similarly, the third conductive connecting piece 17 and/or the fourth conductive connecting piece 18 are slidably disposed on the second grounding circuit 12, and the third conductive portion 121 is disposed on the third conductive connecting piece 17 and electrically connected to the third conductive connecting piece 17, and the fourth conductive portion 122 is disposed on the fourth conductive connecting piece 18 and electrically connected to the fourth conductive connecting piece 18. That is, the third conductive connecting piece 17 is slidably disposed on the second grounding circuit 12, or the fourth conductive connecting piece 18 is slidably disposed on the second injection grounding circuit, or both the third conductive connecting piece 17 and the fourth conductive connecting piece 18 are slidably disposed on the second grounding circuit 12. Thus, the inspector can slide the third conductive connecting piece 17 and/or the fourth conductive connecting piece 18 according to the size of the break 1011 of the radio frequency circuit, that is, slide the third conductive connecting piece 17, or slide the fourth conductive connecting piece 18, or slide the third conductive connecting piece 17 and the fourth conductive connecting piece 18 at the same time, so as to adjust the length of the second grounding circuit 12 between the third conductive connecting piece 17 and the fourth conductive connecting piece 18, so that the third conductive part 121 on the third conductive connecting piece 17 and the fourth conductive part 122 on the fourth conductive connecting piece 18 can be connected to the first grounding circuit 102 at both ends of the break 1011.

In summary, the first conductive connecting piece 15, the second conductive connecting piece 16, the third conductive connecting piece 17 and the fourth conductive connecting piece 18 have the following various conditions, the first conductive connecting piece 15 is slidably disposed on the second rf circuit 11, and the third conductive connecting piece 17 is slidably disposed on the second ground circuit 12; second, the first conductive connecting piece 15 is slidably disposed on the second rf circuit 11, and the fourth conductive connecting piece 18 is slidably disposed on the second ground circuit 12; third, the first conductive connecting piece 15 is slidably disposed on the second radio frequency circuit 11, and the third conductive connecting piece 17 and the fourth conductive connecting piece 18 are both slidably disposed on the second grounding circuit 12; fourth, the second conductive connecting piece 16 is slidably disposed on the second rf circuit 11, and the third conductive connecting piece 17 is slidably disposed on the second ground circuit 12; fifth, the second conductive connecting piece 16 is slidably disposed on the second rf circuit 11, and the fourth conductive connecting piece 18 is slidably disposed on the second ground circuit 12; sixth, the second conductive connecting piece 16 is slidably disposed on the second rf circuit 11, and the third conductive connecting piece 17 and the fourth conductive connecting piece 18 are both slidably disposed on the second ground circuit 12; seventh, the first conductive connecting piece 15 and the second conductive connecting piece 16 are both slidably disposed on the second radio frequency circuit 11, and the third conductive connecting piece 17 is slidably disposed on the second grounding circuit 12; eighth, the first conductive connecting piece 15 and the second conductive connecting piece 16 are both slidably disposed on the second radio frequency circuit 11, and the fourth conductive connecting piece 18 is slidably disposed on the second grounding circuit 12; ninth, the first conductive connecting piece 15 and the second conductive connecting piece 16 are both slidably disposed on the second radio frequency circuit 11, and the third conductive connecting piece 17 and the fourth conductive connecting piece 18 are both slidably disposed on the second grounding circuit 12.

Since the first conductive portion 111, the second conductive portion 112, the third conductive portion 121 and the fourth conductive portion 122 are generally made as relatively thin wires in order to facilitate detection of the break 1011 of the first rf circuit 101. This facilitates control of the contact positions of the first conductive portion 111 and the second conductive portion 112 with the first radio frequency circuit 101, and control of the contact positions of the third conductive portion 121 and the fourth conductive portion 122 with the first ground circuit 102. In addition, the first conductive part 111, the second conductive part 112, the third conductive part 121 and the fourth conductive part 122 are too thick, so that the first conductive part 111, the second conductive part 112, the third conductive part 121 or the fourth conductive part 122 is simultaneously communicated with a plurality of lines when the first radio frequency line 101 is detected, and the problem of short circuit of the first radio frequency line 101 or the problem of short circuit damage of the first grounding line 102 can be prevented, thereby causing the problem of short circuit damage of the circuit board 10.

However, when the first conductive part 111, the second conductive part 112, the third conductive part 121 and the fourth conductive part 122 are all thin wires, if the first conductive part 111 is directly electrically connected to the second rf circuit 11, so that the contact area between the first conductive part 111 and the second rf circuit 11 is very small, there may be electrical connection stability of the first conductive part 111 and the second rf circuit 11, electrical connection stability of the second conductive part 112 and the second rf circuit 11, electrical connection stability of the third conductive part 121 and the second ground circuit 12, and electrical connection stability of the fourth conductive part 122 and the second ground circuit 12, which are poor, so that the first conductive part 111 and the second conductive part 112 are easily separated from the second rf circuit 11, or the third conductive part 121 and the fourth conductive part 122 are easily separated from the second ground circuit 12.

By providing the first conductive connection 15, the first conductive part 111 can be connected to the first conductive connection 15 by soldering, and thus to the second radio frequency line 11. In the welding process, the contact area between the first conductive part 111 and the first conductive connecting piece 15 can be increased by welding the solder on the first conductive part 111, so that the welding stability of the first conductive part 111 and the first conductive connecting piece 15 is improved, and the connection stability of the first conductive part 111 and the second radio frequency circuit 11 is further improved. The reason why the second conductive connecting member 16, the third conductive connecting member 17, and the fourth conductive connecting member 18 are provided is similar to that of the first conductive connecting member 15, and will not be described in detail here.

The materials of the first conductive connecting piece 15, the second conductive connecting piece 16, the third conductive connecting piece 17 and the fourth conductive connecting piece 18 are all conductive materials such as copper, copper alloy or silver. And the first conductive connecting member 15, the second conductive connecting member 16, the third conductive connecting member 17 and the fourth conductive connecting member 18 may each be a sleeve-like structure, such as a square sleeve, a circular sleeve, or the like.

In this embodiment, when the first conductive connecting piece 15 is slidably disposed on the second rf circuit 11 and the third conductive connecting piece 17 is slidably disposed on the second ground circuit 12, the circuit board circuit detection system 100 further includes a first connecting component 13, and the first connecting component 13 is connected to the first conductive connecting piece 15 and the third conductive connecting piece 17. Thus, the inspector can slide the first connecting part 13 to simultaneously slide the first conductive connecting part 15 and the third conductive connecting part 17, which is beneficial to simplifying the inspection steps.

When the second conductive connecting member 16 is slidably disposed on the second rf circuit 11 and the fourth conductive connecting member 18 is slidably disposed on the second ground circuit 12, the circuit board trace inspection system 100 further includes a second connecting member 14, and the second connecting member 14 is connected to the second conductive connecting member 16 and the fourth conductive connecting member 18. Thus, the inspector can slide the second connecting part 14 to simultaneously slide the second conductive connecting part 16 and the fourth conductive connecting part, which is beneficial to simplifying the inspection steps.

For convenience of operation of the inspector, the first conductive connector 15 and the second conductive connector 16 are preferably slidably disposed on the second rf circuit 11, and the third conductive connector 17 and the fourth conductive connector 18 are preferably slidably disposed on the second ground circuit 12. In this way, the inspector can simultaneously adjust the length of the second radio frequency circuit 11 between the first conductive connecting piece 15 and the second conductive connecting piece 16 and the length of the second grounding circuit 12 between the third conductive connecting piece 17 and the fourth conductive connecting piece 18 by sliding the first connecting piece 13 alone, or sliding the second connecting piece 14 alone, or sliding the first connecting piece 13 and the second connecting piece 14 simultaneously, so as to improve the inspection efficiency of the radio frequency circuit; while ensuring that the length of the second radio frequency line 11 between the first conductive connector 15 and the second conductive connector 16 is equal to the length of the second ground line 12 between the third conductive connector 17 and the fourth conductive connector 18, thereby enabling a clean appearance of the radio frequency line when the circuit board line detection system 100 is used to repair the break 1011 on the radio frequency line. The following will describe the first conductive connecting member 15 and the second conductive connecting member 16 slidably disposed on the second rf circuit 11, and the third conductive connecting member 17 and the fourth conductive connecting member 18 slidably disposed on the second ground circuit 12.

It is understood that the first connecting member 13 may be connected between the first conductive connecting member 15 and the third conductive connecting member 17, or sleeved on the outer peripheries of the first conductive connecting member 15 and the third conductive connecting member 17, that is, the first connecting member 13 is wrapped around the first conductive connecting member 15 and the third conductive connecting member 17. Similarly, the second connecting member 14 may be connected between the second conductive connecting member 16 and the fourth conductive connecting member 18, or may be sleeved on the outer peripheries of the second conductive connecting member 16 and the fourth conductive connecting member 18, that is, the second connecting member 14 is wrapped around the second conductive connecting member 16 and the fourth conductive connecting member 18. The embodiment is not particularly limited as long as the first connecting component 13 can simultaneously drive the first conductive connecting piece 15 and the third conductive connecting piece 17 to slide relative to the second radio frequency circuit 11 or the second grounding circuit 12, and the second connecting component 14 can simultaneously drive the second conductive connecting piece 16 and the fourth conductive connecting piece 18 to slide relative to the second radio frequency circuit 11 or the second grounding circuit 12.

Alternatively, the first and second connection members 13 and 14 may be square, oval, cylindrical, or the like, and the present embodiment is not particularly limited.

In addition, when the first connection member 13 and the second connection member 14 are provided, the first connection member 13 may be provided after the first conductive portion 111, the second conductive portion 112, the third conductive portion 121, and the fourth conductive portion 122 are connected to the first conductive connector 15, the second conductive connector 16, the third conductive connector 17, and the fourth conductive connector 18, respectively, so that the first connection member 13 can connect the first conductive connector 15 and the third conductive connector 17, and the second connection member 14 may be provided so that the second connection member 14 can connect the second conductive connector 16 and the fourth conductive connector 18. Or the first connecting part 13 is arranged so that the first connecting part 13 can connect the first conductive connecting piece 15 and the third conductive connecting piece 17, the second connecting part 14 is arranged so that the second connecting part 14 can connect the second conductive connecting piece 16 and the fourth conductive connecting piece 18, and then the first conductive part 111, the second conductive part 112, the third conductive part 121 and the fourth conductive part 122 are respectively connected to the first conductive connecting piece 15, the second conductive connecting piece 16, the third conductive connecting piece 17 and the fourth conductive connecting piece 18. To avoid the first conductive portion 111, the second conductive portion 112, the third conductive portion 121, and the fourth conductive portion 122 from affecting the connection of the first connection member 13 and the second connection member 14. The first mounting mode is preferably adopted in this embodiment.

It is to be noted that, when a structure is adopted in which the first connecting member 13 is connected between the first conductive connecting member 15 and the third conductive connecting member 17, and a structure is adopted in which the second connecting member 14 is connected between the second conductive connecting member 16 and the fourth conductive connecting member 18, the first connecting member 13 and the second connecting member 14 are made of an insulating material. Thereby ensuring that the second radio frequency circuit 11 and the second ground circuit 12 are in insulated connection, and avoiding the circuit board 10 from being broken due to the electric connection between the second radio frequency circuit 11 and the second ground circuit 12.

When the first connecting member 13 is sleeved on the outer periphery of the first conductive connecting member 15 and the third conductive connecting member 17, and the second connecting member 14 is sleeved on the outer periphery of the second conductive connecting member 16 and the fourth conductive connecting member 18, the first connecting member 13 and the second connecting member 14 are sleeved to ensure that the second radio frequency line 11 and the second ground line 12 are in insulating connection, if the first connecting member 13 and the second connecting member 14 are sleeved to electrically connect the second radio frequency line 11 and the second ground line 12, short circuit is caused, and the circuit board line detection system 100 loses the function of detecting the open circuit position of the radio frequency line.

The first connecting part 13 may be an insulating sleeve made of an insulating material, and a first hollowed-out portion 131 is provided at a position of the first connecting part 13 corresponding to the first conductive connecting part 15 to expose the first conductive connecting part 15, and a second hollowed-out portion 132 is provided at a position corresponding to the third conductive connecting part 17 to expose the third conductive connecting part 17, so that when the first connecting part 13 is sleeved on the outer circumferences of the first conductive connecting part 15 and the third conductive connecting part 17, the first conductive connecting part 15 and the third conductive connecting part 17 can be provided at the first hollowed-out portion 131 and the second hollowed-out portion 132, preventing the first connecting part 13 from shielding the first conductive connecting part 15 and the third conductive connecting part 17, making it difficult for the first conductive part 111 to be electrically connected to the first conductive connecting part 15 and the third conductive part 121 to be electrically connected to the third conductive connecting part 17, thereby resulting in a problem that it is difficult for the first conductive part 111 to be electrically connected to the second radio frequency line 11 and the third conductive part 121 to be electrically connected to the second ground line 12. Similarly, the second connecting member 14 may also be an insulating sleeve made of an insulating material, and the second connecting member 14 is provided with a third hollow portion 141 at a position corresponding to the second conductive connecting member 16 and a fourth hollow portion 142 at a position corresponding to the fourth conductive connecting member 18, so that when the second connecting member 14 is sleeved on the outer circumferences of the second conductive connecting member 16 and the fourth conductive connecting member 18, the second conductive connecting member 16 and the fourth conductive connecting member 18 can be disposed at the third hollow portion 141 and the fourth hollow portion 142, so that the second connecting member 14 is prevented from shielding the second conductive connecting member 16 and the fourth conductive connecting member 18, and the second conductive portion 112 is difficult to be electrically connected to the second conductive connecting member 16 and the fourth conductive portion 122 is difficult to be electrically connected to the fourth conductive connecting member 18, thereby causing a problem that the second conductive portion 112 is difficult to be electrically connected to the second radio frequency circuit 11 and the fourth conductive portion 122 is difficult to be electrically connected to the second ground circuit 12.

As another example, the first connecting member 13 is made of an insulating material and a conductive material together, that is, the first connecting member 13 may include a first portion, a second portion and a third portion which are sequentially connected, the first portion is made of a conductive material and is sleeved on the outer circumference of the first conductive connecting member 15, the third portion is made of a conductive material and is sleeved on the outer circumference of the third conductive connecting member 17, the second portion is made of an insulating material and is connected between the first portion and the third portion, so that the first conductive connecting member 15 and the third conductive connecting member 17 are not electrically connected through the first connecting member 13, but are kept in an insulating arrangement, so that insulation between the second radio frequency circuit 11 and the second ground circuit 12 can be ensured, the first conductive portion 111 can be further arranged on the first portion of the first connecting member 13, so that the first conductive portion 111 can be electrically connected to the first conductive connecting member 15 through the first portion of the first connecting member 13, so that the first conductive portion 111 can be electrically connected to the second radio frequency circuit 11, and the third conductive portion 121 can be electrically connected to the third conductive portion 121 through the third conductive portion 121, so that the third conductive portion 121 can be electrically connected to the third conductive portion 121 through the third conductive connecting member 12.

Similarly, the second connecting member 14 is made of an insulating material and a conductive material, that is, the second connecting member 14 may include a fourth portion, a fifth portion and a sixth portion, which are sequentially connected, the fourth portion is made of a conductive material and is sleeved on the outer periphery of the second conductive connecting member 16, the sixth portion is made of a conductive material and is sleeved on the outer periphery of the fourth conductive connecting member 18, and the fifth portion is made of an insulating material and is connected between the fourth portion and the sixth portion, so that the second conductive connecting member 16 and the fourth conductive connecting member 18 are not electrically connected through the second connecting member 14, but are kept in an insulating arrangement, so that insulation between the second radio frequency circuit 11 and the second ground circuit 12 can be ensured, the second conductive portion 112 can be further arranged on the fourth portion of the second connecting member 14, so that the second conductive portion 112 can be electrically connected to the second conductive connecting member 16 through the fourth portion of the second connecting member 14, so that the second conductive portion 112 can be electrically connected to the second radio frequency circuit 11 through the fourth portion 122 can be electrically connected to the fourth conductive connecting member 122 through the fourth portion 122 of the fourth connecting member 14.

In some embodiments, the number of the second grounding wires 12 is two, and the two second grounding wires 12 are respectively disposed at two sides of the second rf wire 11, so that when the circuit board wire detection system 100 of the circuit board wire detection system 100 detects the open circuit position of the first rf wire 101, the second rf wire 11 and the second grounding wire 12 are respectively connected to the positions of the breaks 1011 of the first rf wire 101 and the first grounding wire 102, the transmission of the rf signal through the second rf wire 11 can be better promoted, which is beneficial to improving the transmission effect of the first rf wire 101 on the rf signal.

Of course, the number of the second grounding lines 12 may be one, three, four or more, and may be specifically determined according to the number of the first grounding lines 102 on the periphery of the first rf line 101 and the actual detection situation of the rf line, which is not specifically limited in this embodiment.

Referring to fig. 1, fig. 4 and fig. 5, the present application also discloses a detection method based on the circuit board line detection system 100, by adopting the detection method, the purposes of detecting the open circuit position of the first radio frequency line 101 or the first grounding line 102 and repairing the open circuit position can be achieved, and the production cost of the circuit board 10 can be reduced.

As an alternative embodiment, the detection method comprises the following steps (see fig. 4 for details):

step 201: a circuit board is provided.

The circuit board 10 is provided with a first radio frequency circuit 101, a first grounding circuit 102 and an electronic device 103, the first grounding circuit 102 is arranged at intervals with the first radio frequency circuit 101, the electronic device 103 is connected to the first radio frequency circuit 101, and the electronic device 103 is used for receiving radio frequency signals sent by the first radio frequency circuit 101.

Step 202: and providing a second radio frequency circuit, and electrically connecting the first conductive part and the second conductive part of the second radio frequency circuit to the first radio frequency circuit.

Step 203: and providing a second grounding circuit, and electrically connecting the third conductive part and the fourth conductive part of the second grounding circuit to the first grounding circuit.

Step 204: when the electronic device on the circuit board receives the radio frequency signal sent by the first radio frequency circuit, determining that a fracture exists in the first radio frequency circuit.

Alternatively, the electronic device 103 may be a light bulb or an alarm, or the like. Taking the electronic device 103 as a lamp bead for example, if the first radio frequency circuit 101 connected with the electronic device 103 has a circuit breaking problem, the lamp bead cannot be lightened; if the first conductive portion 111 and the second conductive portion 112 of the second rf circuit 11 are electrically connected to two ends of the detection position of the first rf circuit 101, respectively, when the third conductive portion 121 and the fourth conductive portion 122 of the second ground circuit 12 are electrically connected to two ends of the detection position of the first ground circuit 102, respectively, the rf signal on the first rf circuit 101 can be transmitted to the lamp bead through the second rf circuit 11, and at this time, the lamp bead can be turned on, which indicates that the detection position has the break 1011.

Step 205: and sliding the first conductive part and/or the second conductive part until the length of the second radio frequency circuit between the first conductive part and the second conductive part is matched with the fracture length of the first radio frequency circuit so as to determine the first target length of the second radio frequency circuit.

As can be seen from the foregoing, when the first conductive portion 111 and/or the second conductive portion 112 are slidably disposed on the second rf circuit 11, the first conductive portion 111 can be directly slid, or the second conductive portion 112 can be slid, or both the first conductive portion 111 and the second conductive portion 112 can be slid until the length of the second rf circuit 11 between the first conductive portion 111 and the second conductive portion 112 is matched with the length of the break 1011 of the first rf circuit 101, and at this time, the length of the second rf circuit 11 between the first conductive portion 111 and the second conductive portion 112 is the first target length of the second rf circuit 11.

When the circuit board line detection system 100 further includes the first conductive connecting piece 15 and the second conductive connecting piece 16, and the first conductive connecting piece 15 and the second conductive connecting piece 16 are slidably disposed on the second radio frequency line 11, the first conductive portion 111 is disposed on the first conductive connecting piece 15 and electrically connected to the second radio frequency line 11 through the first conductive connecting piece 15, and the second conductive portion 112 is disposed on the second conductive connecting piece 16 and electrically connected to the second radio frequency line 11 through the second conductive connecting piece 16, the first conductive portion 111 may be driven to slide by directly sliding the first conductive connecting piece 15, or the second conductive portion 112 may be driven to slide by directly sliding the second conductive connecting piece 16, or both the first conductive connecting piece 15 and the second conductive connecting piece 16 may be simultaneously slid to drive the first conductive portion 111 and the second conductive portion 112 until the length of the second radio frequency line 11 between the first conductive portion 111 and the second conductive portion 112 is adapted to the break length of the first radio frequency line 101, and at this time, the length of the second radio frequency line 11 between the first conductive portion 111 and the second conductive portion 112 is the first target length of the second radio frequency line 11.

It should be noted that, when the existence of the fracture 1011 at the detection position is detected, the length of the fracture 1011 may be determined by sliding the first conductive portion 111 and the second conductive portion 112, that is, by sliding the first conductive portion 111 and the second conductive portion 112 toward the center of the detection position, respectively, when the first conductive portion 111 and the second conductive portion 112 slide to the electronic device 103 from the normal operation state to the state incapable of normal operation, the critical position is the position of the fracture 1011, and at this time, the distance between the first conductive portion 111 and the second conductive portion 112 on the first radio frequency circuit 101 is the length of the fracture 1011.

Step 206: and sliding the third conductive part and/or the fourth conductive part until the length of the second grounding circuit between the third conductive part and the fourth conductive part is matched with the fracture length of the first radio frequency circuit so as to determine the second target length of the second grounding circuit.

As can be seen from the foregoing, when the third conductive portion 121 and/or the fourth conductive portion 122 are slidably disposed on the second grounding trace 12, the third conductive portion 121 may be directly slid, the fourth conductive portion 122 may be slid, or both the third conductive portion 121 and the fourth conductive portion 122 may be slid until the length of the second rf trace 11 between the third conductive portion 121 and the fourth conductive portion 122 is matched with the length of the break 1011 of the first rf trace 101, and at this time, the length of the second grounding trace 12 between the third conductive portion 121 and the fourth conductive portion 122 is the second target length of the second grounding trace 12.

When the circuit board line detection system 100 further includes the third conductive connecting piece 17 and the fourth conductive connecting piece 18, and the third conductive connecting piece 17 and the fourth conductive connecting piece 18 are slidably disposed on the second grounding line 12, the third conductive portion 121 is disposed on the third conductive connecting piece 17 and electrically connected to the second grounding line 12 through the third conductive connecting piece 17, and the fourth conductive portion 122 is disposed on the fourth conductive connecting piece 18 and electrically connected to the second grounding line 12 through the fourth conductive connecting piece 18, the third conductive portion 121 may be driven to slide by directly sliding the third conductive connecting piece 17, or the fourth conductive portion 122 may be driven to slide by directly sliding the fourth conductive connecting piece 18, or both the third conductive connecting piece 17 and the fourth conductive connecting piece 18 may be simultaneously slid to drive the third conductive portion 121 and the fourth conductive portion 122 until the length of the second grounding line 12 between the third conductive portion 121 and the fourth conductive portion 122 is adapted to the length of the break 1011 of the first radio frequency line 101 at this time, and the second grounding line 12 between the third conductive portion 121 and the fourth conductive portion 122 is the second grounding line 12, i.e. the second target length.

Step 207: and cutting off other parts of the second radio frequency circuit except the first target length.

Namely, the length of the second radio frequency circuit 11 is cut to be the first target length, so that the condition that the circuit board 10 is disconnected due to the fact that the redundant second radio frequency circuit 11 is arranged on the circuit board 10 is avoided.

Step 208: and cutting off other parts of the second grounding line except the second target length.

Namely, the length of the second grounding wire 12 is cut to be the second target length, so that the condition that the circuit board 10 is disconnected due to the fact that the redundant second grounding wire 12 is arranged on the circuit board 10 is avoided.

Step 209: and welding the first conductive part and the second conductive part at the fracture position of the first radio frequency circuit.

In the foregoing, in order to facilitate the detection of the rf circuit by the circuit board circuit detection system 100, the first conductive portion 111 and the second conductive portion 112 are preferably thin wires, for example, the first conductive portion 111 and the second conductive portion 112 are directly welded to the first rf circuit 101, and the first conductive portion 111 and the second conductive portion 112 are easily broken due to the external force, so that the first rf circuit 101 is broken. Therefore, before the first conductive portion 111 and the second conductive portion 112 are soldered to the first radio frequency circuit 101, the first conductive portion 111 and the second conductive portion 112 may be replaced with thicker wires, such as wires having the same thickness as the first radio frequency circuit 101, so as to improve the stress capability of the first conductive portion 111 and the second conductive portion 112.

Since the first conductive part 111 and the second conductive part 112 are directly welded on the first radio frequency circuit 101, the contact area between the first conductive part 111 and the second conductive part 112 and the first radio frequency circuit 101 is small, so that the connection stability between the first conductive part 111 and the second conductive part 112 and the first radio frequency circuit 101 is poor, and the first conductive part 111 and the second conductive part 112 are easy to separate from the first radio frequency circuit 101. Thus, in some embodiments, the pads 19 are soldered at the ends of the first conductive portion 111 and the second conductive portion 112 that are soldered to the first rf circuit 101 prior to electrically connecting the circuit board trace inspection system 100 to the circuit board 10 at the open circuit location. In the welding process, the welding area between the first conductive portion 111 and the bonding pad 19 can be increased by solder, so that the welding area between the first conductive portion 111 and the bonding pad 19 is larger than the welding area when the first conductive portion 111 is directly welded to the first rf circuit 101, and the principle of the second conductive portion 112 is similar, which is not repeated here. That is, the provision of the pads 19 enables the first conductive part 111 and the second conductive part 112 to be electrically connected with the first radio frequency circuit 101 through the pads 19, respectively, thereby improving the soldering stability of the first conductive part 111 and the second conductive part 112 with the first radio frequency circuit 101.

Step 210: and welding the third conductive part and the fourth conductive part at the position of the first grounding circuit corresponding to the fracture of the first radio frequency circuit.

Before the third conductive part 121 and the fourth conductive part 122 are welded at the position of the first grounding line 102 corresponding to the fracture 1011 of the first radio frequency line 101, the third conductive part 121 and the fourth conductive part 122 can be replaced by thicker wires, such as wires with the same thickness as the first radio frequency line 101, so as to improve the stress capability of the third conductive part 121 and the fourth conductive part 122; and one end bonding pad 19 bonded to the first ground line 102 at the third conductive portion 121 and the fourth conductive portion 122. The reason for this is specifically referred to step 209, and will not be described in detail here.

As another alternative embodiment, the detection method comprises the following steps (see fig. 5 for details):

Step 301: a circuit board is provided.

Step 302: and providing a second radio frequency circuit, and electrically connecting the first conductive part and the second conductive part of the second radio frequency circuit to the first radio frequency circuit.

Step 303: and providing a second grounding circuit, and electrically connecting the third conductive part and the fourth conductive part of the second grounding circuit to the first grounding circuit.

Step 304: when an electronic device on the circuit board receives a radio frequency signal sent by a first radio frequency circuit, determining that a fracture exists in the first radio frequency circuit.

Step 305: the first conductive portion and the third conductive portion are slid synchronously, and/or the second conductive portion and the fourth conductive portion are slid synchronously, until the length of the second radio frequency line 11 between the first conductive portion and the second conductive portion, and until the length of the second ground line between the third conductive portion and the fourth conductive portion, are adapted to the fracture length of the first radio frequency line to determine a first target length of the second radio frequency line, and a second target length of the second ground line is determined.

As can be seen from the foregoing, when the first connecting member 13 is connected between the first conductive portion 111 and the third conductive portion 121 and the second connecting member 14 is connected between the second conductive portion 112 and the fourth conductive portion 122, or when the circuit board line inspection system 100 further includes the first conductive connecting member 15, the second conductive connecting member 16, the third conductive connecting member 17, the fourth conductive connecting member 18, the first connecting member 13 and the second connecting member 14, the first conductive connecting member 15 and the second conductive connecting member 16 are slidably disposed on the second rf line 11, the third conductive connecting member 17 and the fourth conductive connecting member 18 are slidably disposed on the second ground line 12, the first conductive portion 111 is disposed on the first conductive connecting member 15 and electrically connected to the second rf line 11 through the first conductive connecting member 15, the second conductive portion 112 is disposed on the second conductive connecting member 16 and electrically connected to the second rf line 11 through the second conductive connecting member 16, the third conductive part 121 is disposed on the third conductive connecting piece 17 and electrically connected to the second grounding circuit 12 through the third conductive connecting piece 17, the fourth conductive part 122 is disposed on the fourth conductive connecting piece 18 and electrically connected to the second grounding circuit 12 through the fourth conductive connecting piece 18, and when the first connecting member 13 is connected to the first conductive connecting piece 15 and the third conductive connecting piece 17 and the second connecting member 14 is connected to the second conductive connecting piece 16 and the fourth conductive connecting piece 18, the first conductive part 111 and the third conductive part 121 can be synchronously slid by sliding the first connecting member 13, or the second conductive part 112 and the fourth conductive part 122 can be synchronously slid by sliding the second connecting member 14, or the first conductive part 111, the second conductive part 112, the third conductive part 121 can be synchronously slid by sliding the first connecting member 13 and the second connecting member 14, the purpose of the third conductive part 121 and the fourth conductive part 122 is to the length of the second radio frequency line 11 between the first conductive part 111 and the second conductive part 112, and the length of the second ground line 12 between the third conductive part 121 and the fourth conductive part 122 are adapted to the length of the break 1011 of the first radio frequency line 101. At this time, the length of the second rf circuit 11 between the first conductive portion 111 and the second conductive portion 112 is the first target length of the second rf circuit 11, and the length of the second ground circuit 12 between the third conductive portion 121 and the fourth conductive portion 122 is the second target length of the second ground circuit 12.

Note that the method for determining the length of the break 1011 is similar to the foregoing embodiment, and will not be described here.

Step 306: and cutting off other parts of the second radio frequency circuit except the first target length.

Step 307: and cutting off other parts of the second grounding line except the second target length.
