The technical solution of the present invention will be further described with reference to the following embodiments and the accompanying drawings.
Referring to fig. 1 to fig. 3 together, the present application discloses a circuit board line detection system, where the circuit board line detection system 100 includes a circuit board 10, a second rf line 11, and a second ground line 12 spaced apart from the second rf line 11, the rf line may include a first rf line 101, a first ground line 102, and an electronic device 103 connected to the first rf line 101, the first ground line 102 is used to enable an rf signal to be transmitted along the first rf line 101, and the electronic device 103 is used to receive an rf signal sent by the first rf line 101. The second rf line 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 line 101, the second ground line 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 line 102.
The circuit board line detection system 100 provided by the present application enables the second rf line 11 to transmit rf signals by electrically connecting the first conductive part 111 and the second conductive part 112 disposed on the second rf line 11 with two ends of the detection area of the first rf line 101, and electrically connecting the third conductive part 121 and the fourth conductive part 122 disposed on the second ground line 12 with two ends of the detection area of the first ground line 102. When the detection area has a problem of circuit breaking, the second rf line 11 can connect the first rf lines 101 at two ends of the circuit breaking position, so that the rf signal can be continuously transmitted to the electronic device 103 on the first rf channel, and at this time, the electronic device 103 can be normally used. That is, when the first rf line 101 or the first ground line 102 has an open circuit problem, the first conductive part 111 and the second conductive part 112 on the second rf line 11 of the circuit board line inspection system 100 are connected to both ends of the inspection area of the first rf line 101, and the third conductive part 121 and the fourth conductive part 122 on the second ground line 12 are connected to both ends of the inspection area of the first ground line 102. Thus, when there is a problem of open circuit in the detection area, the rf signal on the first rf line 101 can be transmitted from one end of the open circuit position to the second rf line 11, and then transmitted back to the other end of the open circuit position through the second rf line 11 to be re-transmitted back to the first rf line 101, so that the electronic device 103 can receive the rf signal on the first rf line 101, and the electronic device 103 can be normally used. In addition, after the open circuit position on the first rf line 101 or the first ground line 102 is detected, the circuit board line detection system 100 can be electrically connected to the open circuit position, that is, two ends of the open circuit position are electrically connected to the second rf line 11 and the second ground line 12, so as to achieve the purpose of repairing the first rf line 101 or the first ground line 102. In addition, since the circuit board line detection system 100 provided by the present application can detect and repair the first rf line 101 or the first ground line 102, the failed first rf line 101 or the first ground line 102 does not need to be replaced together with the electronic device 103 connected thereto, which is beneficial to reducing the production cost of the circuit board 10.
Optionally, the electronic device 103 may be a lamp bead or an alarm, etc. Illustratively, when the electronic device 103 is a lamp bead, if the first radio frequency circuit 101 connected to the electronic device 103 has a problem of open circuit, the lamp bead cannot be lit; if the first conductive part 111 and the second conductive part 112 of the second rf line 11 are electrically connected to two ends of the open position of the first rf line 101, respectively, and the third conductive part 121 and the fourth conductive part 122 of the second ground line 12 are electrically connected to two ends of the open position of the first ground line 102, respectively, the rf signal on the first rf line 101 can be transmitted to the lamp bead through the second rf line 11, and the lamp bead can be lit up at this time.
It is worth noting that there are three conditions for the open circuit state of the rf circuit, the first is that the first rf circuit 101 has an open circuit problem, and the first grounding circuit 102 is normal, at this time, the rf circuit cannot realize the function of transmitting rf signals, at this time, the electronic device 103 cannot work, if the lamp bead cannot be lighted; the second is that the first radio frequency circuit 101 and the first grounding circuit 102 both have a problem of open circuit, at this time, the radio frequency circuit cannot realize the function of transmitting radio frequency signals, at this time, the electronic device 103 cannot work, and if a lamp bead cannot be lighted; the third type of the first radio frequency circuit 101 is normal, and the first grounding circuit 102 has a problem of open circuit, at this time, the radio frequency circuit has a poor radio frequency signal transmission effect, and at this time, the electronic device 103 cannot work or cannot work normally, for example, the lamp bead cannot be lighted up or the brightness of the lamp bead cannot reach the expected brightness.
The specific structure of the circuit board trace detection system 100 will be described in detail below by taking the case where the first rf trace 101 is broken and the first ground trace 102 is normal. That is, the first rf line 101 has a break 1011 (see fig. 2 for details).
In some embodiments, to ensure that the rf signals are transmitted on the first rf line 101 and the second rf line 11 with the same effect, the impedance of the second rf line 11 needs to be equal to the impedance of the first rf line 101. Thus, the transmission effect of the radio frequency signal on the first radio frequency line 101 and the second radio frequency line 11 is the same, the accuracy of the circuit board line detection system 100 for detecting the open circuit position of the radio frequency line can be improved, and the repaired radio frequency line is ensured not to influence the transmission of the radio frequency signal.
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, which may be determined according to actual situations.
As an alternative embodiment, the first conductive part 111 and/or the second conductive part 112 may be slidably disposed on the second rf line 11, and/or the third conductive part 121 and/or the fourth conductive part 122 may be slidably disposed on the second ground line 12. That is, the following conditions exist: first, the first conductive part 111 can be slidably disposed on the second rf circuit 11, and the third conductive part 121 can be slidably disposed on the second ground circuit 12; second, the first conductive part 111 can be slidably disposed on the second rf line 11, and the fourth conductive part 122 can be slidably disposed on the second ground line 12; third, the first conductive part 111 can be slidably disposed on the second rf line 11, and both the third conductive part 121 and the fourth conductive part 122 can be slidably disposed on the second ground line 12; fourth, the second conductive part 112 is slidably disposed on the second rf line 11, and the third conductive part 121 is slidably disposed on the second ground line 12; fifth, the second conductive part 112 is slidably disposed on the second rf line 11, and the fourth conductive part 122 is slidably disposed on the second ground line 12; sixthly, the second conductive part 112 is slidably disposed on the second rf line 11, and both the third conductive part 121 and the fourth conductive part 122 are slidably disposed on the second ground line 12; seventh, the first conductive part 111 and the second conductive part 112 can be slidably disposed on the second rf line 11, and the third conductive part 121 can be slidably disposed on the second ground line 12; eighth, the first conductive part 111 and the second conductive part 112 can be slidably disposed on the second rf line 11, and the fourth conductive part 122 can be slidably disposed on the second ground line 12; ninth, the first conductive portion 111 and the second conductive portion 112 can be slidably disposed on the second rf trace 11, and the third conductive portion 121 and the fourth conductive portion 122 can be slidably disposed on the second ground trace 12. This arrangement can facilitate adjustment of the length of the second rf 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 rf 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 rf 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 part 111 is slidably disposed on the second rf trace 11 and the third conductive part 121 is slidably disposed on the second ground trace 12, the circuit board trace detection system 100 further includes a first connecting component 13, wherein the first connecting component 13 is connected to the first conductive part 111 and the third conductive part 121. Thus, the inspector can slide the first conductive part 111 and the second conductive part 112 simultaneously by sliding the first connecting member 13, which is advantageous for simplifying the inspecting process of the inspector.
When the second conductive part 112 is slidably disposed on the second rf line 11 and the fourth conductive part 122 is slidably disposed on the second ground line 12, the circuit board line inspection system 100 further includes a second connecting part 14, wherein the second connecting part 14 is connected to the second conductive part 112 and the fourth conductive part 122. Thus, the inspector can slide the second connecting member 14 to slide the second conductive part 112 and the fourth conductive part 122 at the same time, which is advantageous for simplifying the inspecting process of the inspector.
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/is slidably disposed on the second radio frequency circuit 11, the first conductive portion 111 is disposed on the first conductive connecting piece 15 and is electrically connected to the second radio frequency circuit 11 through the first conductive connecting piece 15, the second conductive portion 112 is disposed on the second conductive connecting piece 16 and is 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 fracture 1011 of the radio frequency line, 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 simultaneously, so as to adjust the length of the second radio frequency line 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 line 101 at two ends of the fracture 1011.
Similarly, the third conductive connecting element 17 and/or the fourth conductive connecting element 18 are slidably disposed on the second grounding line 12, the third conductive portion 121 is disposed on the third conductive connecting element 17 and electrically connected to the third conductive connecting element 17, and the fourth conductive portion 122 is disposed on the fourth conductive connecting element 18 and electrically connected to the fourth conductive connecting element 18. That is, the third conductive connecting element 17 can be slidably disposed on the second ground trace 12, or the fourth conductive connecting element 18 can be slidably disposed on the second ground trace, or both the third conductive connecting element 17 and the fourth conductive connecting element 18 can be slidably disposed on the second ground trace 12. Thus, the inspector can slide the third conductive connector 17 and/or the fourth conductive connector 18 according to the size of the fracture 1011 of the radio frequency line, i.e., slide the third conductive connector 17, or slide the fourth conductive connector 18, or slide the third conductive connector 17 and the fourth conductive connector 18 at the same time, thereby adjusting the length of the second ground line 12 between the third conductive connector 17 and the fourth conductive connector 18, and enabling the third conductive part 121 on the third conductive connector 17 and the fourth conductive part 122 on the fourth conductive connector 18 to be connected to the first ground lines 102 at two ends of the fracture 1011.
In summary, the first conductive connecting element 15, the second conductive connecting element 16, the third conductive connecting element 17 and the fourth conductive connecting element 18 may be arranged in a plurality of ways, the first conductive connecting element 15 may be slidably disposed on the second rf line 11, and the third conductive connecting element 17 may be slidably disposed on the second ground line 12; secondly, the first conductive connecting piece 15 can be slidably arranged on the second radio frequency circuit 11, and the fourth conductive connecting piece 18 can be slidably arranged on the second grounding circuit 12; thirdly, the first conductive connecting piece 15 is slidably disposed on the second rf line 11, and both the third conductive connecting piece 17 and the fourth conductive connecting piece 18 are slidably disposed on the second ground line 12; fourthly, the second conductive connecting piece 16 can be slidably arranged on the second radio frequency circuit 11, and the third conductive connecting piece 17 can be slidably arranged on the second grounding circuit 12; fifth, the second conductive connecting element 16 is slidably disposed on the second rf line 11, and the fourth conductive connecting element 18 is slidably disposed on the second ground line 12; sixthly, the second conductive connecting piece 16 can be slidably arranged on the second radio frequency circuit 11, and the third conductive connecting piece 17 and the fourth conductive connecting piece 18 can be slidably arranged on the second grounding circuit 12; seventh, the first conductive connecting piece 15 and the second conductive connecting piece 16 can be slidably disposed on the second rf line 11, and the third conductive connecting piece 17 can be slidably disposed on the second ground line 12; eighthly, both the first conductive connecting piece 15 and the second conductive connecting piece 16 can be slidably arranged on the second radio frequency circuit 11, and the fourth conductive connecting piece 18 can be slidably arranged on the second grounding circuit 12; ninth, the first conductive connecting element 15 and the second conductive connecting element 16 are slidably disposed on the second rf line 11, and the third conductive connecting element 17 and the fourth conductive connecting element 18 are slidably disposed on the second ground line 12.
For the convenience of detecting the fracture 1011 of the first rf line 101, the first conductive portion 111, the second conductive portion 112, the third conductive portion 121 and the fourth conductive portion 122 are generally made into relatively thin wires. This is advantageous for controlling the contact position of the first and second conductive portions 111 and 112 with the first rf line 101, and for controlling the contact position of the third and fourth conductive portions 121 and 122 with the first ground line 102. In addition, it can also prevent the problem that when the first rf circuit 101 is detected, the first conductive part 111, the second conductive part 112, the third conductive part 121, or the fourth conductive part 122 is connected to multiple lines at the same time due to the fact that the first conductive part 111, the second conductive part 112, the third conductive part 121, or the fourth conductive part 122 is too thick, which causes the problem of short circuit of the first rf circuit 101 or the first grounding circuit 102, and thus causes the short circuit damage of the circuit board 10.
However, when the first conductive portion 111, the second conductive portion 112, the third conductive portion 121, and the fourth conductive portion 122 are all thin wires, if the first conductive portion 111 is directly electrically connected to the second rf line 11, so that the contact area between the first conductive portion 111 and the second rf line 11 is very small, there may be poor electrical connection stability between the first conductive portion 111 and the second rf line 11, electrical connection stability between the second conductive portion 112 and the second rf line 11, electrical connection stability between the third conductive portion 121 and the second ground line 12, and electrical connection stability between the fourth conductive portion 122 and the second ground line 12, so that the first conductive portion 111 and the second conductive portion 112 may be easily separated from the second rf line 11, or the third conductive portion 121 and the fourth conductive portion 122 may be easily separated from the second ground line 12.
The first conductive connection 15 is provided so that the first conductive portion 111 can be connected to the first conductive connection 15 by soldering, and thus to the second rf line 11. In the soldering process, the contact area between the first conductive part 111 and the first conductive connecting piece 15 can be increased by the solder soldered on the first conductive part 111, so that the soldering stability between the first conductive part 111 and the first conductive connecting piece 15 is improved, and the connection stability between the first conductive part 111 and the second radio frequency circuit 11 is further improved. The second conductive connecting member 16, the third conductive connecting member 17 and the fourth conductive connecting member 18 are provided for the same reason as the first conductive connecting member 15, and are not described in detail herein.
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 made of 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 be sleeve-shaped structures, such as a square sleeve, a circular sleeve, etc.
In this embodiment, when the first conductive connecting element 15 is slidably disposed on the second rf trace 11 and the third conductive connecting element 17 is slidably disposed on the second ground trace 12, the circuit board trace detection system 100 further includes a first connecting element 13, wherein the first connecting element 13 is connected to the first conductive connecting element 15 and the third conductive connecting element 17. Thus, the detection personnel 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 detection steps.
When the second conductive connector 16 is slidably disposed on the second rf trace 11 and the fourth conductive connector 18 is slidably disposed on the second ground trace 12, the circuit board trace detection system 100 further includes a second connection component 14, wherein the second connection component 14 is connected to the second conductive connector 16 and the fourth conductive connector 18. Thus, the inspector can slide the second connecting member 14 to slide the second conductive connecting member 16 and the fourth conductive connecting member simultaneously, which is advantageous for simplifying the inspecting process.
For the convenience of the operation of the detecting person, in this embodiment, it is preferable that the first conductive connecting part 15 and the second conductive connecting part 16 are slidably disposed on the second rf line 11, and the third conductive connecting part 17 and the fourth conductive connecting part 18 are slidably disposed on the second ground line 12. In this way, the inspector can slide the first connecting part 13 alone, or slide the second connecting part 14 alone, or slide the first connecting part 13 and the second connecting part 14 simultaneously, so as to adjust the length of the second rf line 11 between the first conductive connecting part 15 and the second conductive connecting part 16 and the length of the second ground line 12 between the third conductive connecting part 17 and the fourth conductive connecting part 18 simultaneously, thereby improving the detection efficiency of the rf line; meanwhile, the length of the second radio frequency line 11 between the first conductive connecting piece 15 and the second conductive connecting piece 16 is equal to the length of the second grounding line 12 between the third conductive connecting piece 17 and the fourth conductive connecting piece 18, so that when the circuit board line detection system 100 is used for repairing a fracture 1011 on the radio frequency line, the appearance of the radio frequency line can be neat. The first conductive connecting element 15 and the second conductive connecting element 16 are slidably disposed on the second rf line 11, and the third conductive connecting element 17 and the fourth conductive connecting element 18 are slidably disposed on the second ground line 12.
It is understood that the first connection part 13 may be connected between the first conductive connection part 15 and the third conductive connection part 17, or may be sleeved on the outer peripheries of the first conductive connection part 15 and the third conductive connection part 17, that is, the first connection part 13 is covered around the first conductive connection part 15 and the third conductive connection part 17. Similarly, the second connection part 14 may be connected between the second conductive connection part 16 and the fourth conductive connection part 18, or sleeved around the second conductive connection part 16 and the fourth conductive connection part 18, that is, the second connection part 14 is wrapped around the second conductive connection part 16 and the fourth conductive connection part 18. As long as it is ensured that the first connecting part 13 can simultaneously drive the first conductive connecting part 15 and the third conductive connecting part 17 to slide relative to the second rf line 11 or the second ground line 12, and the second connecting part 14 can simultaneously drive the second conductive connecting part 16 and the fourth conductive connecting part 18 to slide relative to the second rf line 11 or the second ground line 12, the embodiment is not particularly limited.
Alternatively, the first and second connection parts 13 and 14 may be square, oval, cylindrical, or the like, and the embodiment is not particularly limited.
In addition, when the first connection member 13 and the second connection member 14 are provided, the first conductive portion 111, the second conductive portion 112, the third conductive portion 121, and the fourth conductive portion 122 may be connected to the first conductive connector 15, the second conductive connector 16, the third conductive connector 17, and the fourth conductive connector 18, respectively, and then the first connection member 13 may be provided 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 component 13 is first arranged so that the first connecting component 13 can connect the first conductive connecting piece 15 and the third conductive connecting piece 17, the second connecting component 14 is arranged so that the second connecting component 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. In order to avoid the first conductive part 111, the second conductive part 112, the third conductive part 121 and the fourth conductive part 122 from affecting the connection between the first connecting part 13 and the second connecting part 14. The first mounting mode is preferably adopted in the present embodiment.
It is to be noted that when a structure in which the first connection part 13 is connected between the first conductive connector 15 and the third conductive connector 17 and a structure in which the second connection part 14 is connected between the second conductive connector 16 and the fourth conductive connector 18 are employed, the first connection part 13 and the second connection part 14 are made of an insulating material. Therefore, the second radio frequency line 11 and the second grounding line 12 are ensured to be in insulated connection, and the circuit board 10 is prevented from being disconnected due to the fact that the second radio frequency line 11 and the second grounding line 12 are electrically connected.
When the first connecting part 13 is sleeved on the peripheries of the first conductive connecting part 15 and the third conductive connecting part 17, and the second connecting part 14 is sleeved on the peripheries of the second conductive connecting part 16 and the fourth conductive connecting part 18, the first connecting part 13 and the second connecting part 14 are sleeved on the first connecting part 13 and the second connecting part 14, which are required to ensure that the second rf line 11 and the second ground line 12 are connected in an insulating manner, if the first connecting part 13 and the second connecting part 14 are sleeved on the second connecting part 11 and the second ground line 12, which will cause a short circuit, the circuit board line detection system 100 loses the function of detecting the open circuit position of the rf line.
In one example, the first connecting part 13 may be an insulating sleeve made of an insulating material, and the first connecting part 13 is provided with a first hollow portion 131 at a position corresponding to the first conductive connecting part 15 to expose the first conductive connecting part 15, and a second hollow portion 132 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 circumference 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 hollow portion 131 and the second hollow portion 132 to prevent the first connecting part 13 from shielding the first conductive connecting part 15 and the third conductive connecting part 17, so that the first conductive part 111 and the third conductive part 121 are difficult to be electrically connected to the first conductive connecting part 15 and the third conductive connecting part 17, thereby causing a problem that the first conductive portion 111 is difficult to be electrically connected to the second radio frequency line 11 and the third conductive portion 121 is difficult to be electrically connected to the second ground line 12. Similarly, the second connecting part 14 may also be an insulating sleeve made of an insulating material, and a third hollow-out portion 141 is provided at a position of the second connecting part 14 corresponding to the second conductive connecting part 16, and a fourth hollow-out portion 142 is provided at a position corresponding to the fourth conductive connecting part 18, so that when the second connection part 14 is fitted around the outer circumferences of the second conductive connection 16 and the fourth conductive connection 18, so that the second conductive connecting piece 16 and the fourth conductive connecting piece 18 can be disposed at the third hollow-out portion 141 and the fourth hollow-out portion 142, and the second connecting part 14 is prevented from shielding the second conductive connecting piece 16 and the fourth conductive connecting piece 18, so that the second conductive portion 112 is difficult to be electrically connected to the second conductive connecting piece 16 and the fourth conductive portion 122 is difficult to be electrically connected to the fourth conductive connecting piece 18, thereby causing a problem that the second conductive portion 112 is difficult to be electrically connected to the second radio frequency line 11 and the fourth conductive portion 122 is difficult to be electrically connected to the second ground line 12.
Alternatively, the first connecting part 13 may be made of an insulating material and a conductive material, that is, the first connecting part 13 may include a first portion, a second portion and a third portion, which are connected in sequence, the first portion is made of a conductive material and is disposed at the outer periphery of the first conductive connecting part 15, the third portion is made of a conductive material and is disposed at the outer periphery of the third conductive connecting part 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 part 15 and the third conductive connecting part 17 are not electrically connected through the first connecting part 13, but are kept in an insulating arrangement, which can ensure the insulation between the second rf line 11 and the second ground line 12, and the first conductive part 111 can be disposed on the first portion of the first connecting part 13, so that the first conductive part 111 can be electrically connected to the first conductive connecting part 15 through the first portion of the first connecting part 13, so that the first conductive portion 111 is electrically connected to the second rf line 11, and the third conductive portion 121 can be disposed on the third portion of the first connecting member 13, so that the third conductive portion 121 can be electrically connected to the third conductive connector 17 through the third portion of the first connecting member 13, so that the third conductive portion 121 is electrically connected to the second ground line 12.
Similarly, the second connecting component 14 is made of an insulating material and a conductive material, that is, the second connecting component 14 may include a fourth portion, a fifth portion and a sixth portion, which are connected in sequence, the fourth portion is made of a conductive material and is sleeved on the outer periphery of the second conductive connecting component 16, the sixth portion is made of a conductive material and is sleeved on the outer periphery of the fourth conductive connecting component 18, 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 component 16 and the fourth conductive connecting component 18 are not electrically connected through the second connecting component 14, but are kept in an insulating arrangement, which not only can ensure the insulation between the second rf line 11 and the second ground line 12, but also can arrange the second conductive portion 112 on the fourth portion of the second connecting component 14, so that the second conductive portion 112 can be electrically connected to the second conductive connecting component 16 through the fourth portion of the second connecting component 14, so that the second conductive portion 112 is electrically connected to the second rf line 11, and the fourth conductive portion 122 can be disposed on the sixth portion of the second connecting member 14, so that the fourth conductive portion 122 can be electrically connected to the fourth conductive connector 18 through the sixth portion of the second connecting member 14, so that the fourth conductive portion 122 is electrically connected to the second ground line 12.
In some embodiments, the number of the second grounding lines 12 is two, and the two second grounding lines 12 are respectively disposed on two sides of the second rf line 11, so that when the circuit board line detection system 100 detects the open circuit position of the first rf line 101, and then the second rf line 11 and the second grounding line 12 are respectively connected to the fracture 1011 positions of the first rf line 101 and the first grounding line 102, the rf signal can be better promoted to pass through the second rf line 11, which is beneficial to improving the transmission effect of the first rf line 101 on the rf signal.
Of course, the number of the second ground lines 12 may also be one, three, four, or more, and specifically may be determined according to the number of the first ground lines 102 on the periphery of the first radio frequency line 101 and the actual detection condition of the radio frequency 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, which can detect and repair the open circuit position of the first rf line 101 or the first ground line 102, and reduce the production cost of the circuit board 10.
As an alternative embodiment, the detection method includes the following steps (see fig. 4 in particular):
step 201: a circuit board is provided.
The circuit board 10 is provided with a first rf line 101, a first ground line 102 and an electronic device 103, the first ground line 102 and the first rf line 101 are arranged at an interval, the electronic device 103 is connected to the first rf line 101, and the electronic device 103 is configured to receive an rf signal transmitted by the first rf line 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: providing a second grounding circuit, and electrically connecting a third conductive part and a fourth conductive part of the second grounding circuit to the first grounding circuit.
Step 204: when the electronic device on the circuit board receives a radio frequency signal sent by the first radio frequency line, it is determined that a fracture exists in the first radio frequency line.
Optionally, the electronic device 103 may be a lamp bead or an alarm, etc. Taking the electronic device 103 as an example of a lamp bead, if the first radio frequency circuit 101 connected to the electronic device 103 has a problem of open circuit, the lamp bead cannot be turned on; if the first conductive part 111 and the second conductive part 112 of the second rf line 11 are electrically connected to two ends of the detection position of the first rf line 101, respectively, and the third conductive part 121 and the fourth conductive part 122 of the second ground line 12 are electrically connected to two ends of the detection position of the first ground line 102, respectively, the rf signal on the first rf line 101 can be transmitted to the lamp bead through the second rf line 11, and at this time, the lamp bead can be lit up, indicating that there is a fracture 1011 at the detection position.
Step 205: and sliding the first conductive part and/or the second conductive part until the length of a second radio frequency line between the first conductive part and the second conductive part is matched with the fracture length of the first radio frequency line so as to determine a first target length of the second radio frequency line.
As can be seen from the foregoing, when the first conductive part 111 and/or the second conductive part 112 are slidably disposed on the second rf line 11, the first conductive part 111, the second conductive part 112, or both the first conductive part 111 and the second conductive part 112 may be directly slid until the length of the second rf line 11 between the first conductive part 111 and the second conductive part 112 matches the length of the fracture 1011 of the first rf line 101, where the length of the second rf line 11 between the first conductive part 111 and the second conductive part 112 is the first target length of the second rf line 11.
When the circuit board line detection system 100 further includes a first conductive connecting part 15 and a second conductive connecting part 16, and the first conductive connecting part 15 and the second conductive connecting part 16 can be slidably disposed on the second radio frequency line 11, the first conductive part 111 is disposed on the first conductive connecting part 15 and electrically connected to the second radio frequency line 11 through the first conductive connecting part 15, and the second conductive part 112 is disposed on the second conductive connecting part 16 and electrically connected to the second radio frequency line 11 through the second conductive connecting part 16, the first conductive part 111 can be driven to slide by directly sliding the first conductive connecting part 15, or the second conductive part 112 can be driven to slide by directly sliding the second conductive connecting part 16, or the first conductive connecting part 15 and the second conductive connecting part 16 are simultaneously slid to drive the first conductive part 111 and the second conductive part 112 to slide, until the length of the second radio frequency line 11 located between the first conductive part 111 and the second conductive part 112 is matched with the fracture length 1011 of the first radio frequency line 101, at this time, the length of the second rf line 11 between the first conductive part 111 and the second conductive part 112 is the first target length of the second rf line 11.
It should be noted that, when it is detected that there is a fracture 1011 at the detection position, the length of the fracture 1011 may be determined by sliding the first conductive part 111 and the second conductive part 112, that is, by sliding the first conductive part 111 and the second conductive part 112 respectively towards the center of the detection position, when the first conductive part 111 and the second conductive part 112 slide to the state where the electronic device 103 is changed from the normal operating state to the abnormal operating state, the critical point is the position of the fracture 1011, and at this time, the distance between the first conductive part 111 and the second conductive part 112 on the first rf line 101 is the fracture length 1011.
Step 206: and sliding the third conductive part and/or the fourth conductive part until the length of a 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 a second target length of the second grounding circuit.
As can be seen from the foregoing, when the third conductive part 121 and/or the fourth conductive part 122 are/is slidably disposed on the second ground line 12, the third conductive part 121, the fourth conductive part 122, or both the third conductive part 121 and the fourth conductive part 122 may be directly slid until the length of the second rf line 11 located between the third conductive part 121 and the fourth conductive part 122 matches the length of the fracture 1011 of the first rf line 101, and at this time, the length of the second ground line 12 located between the third conductive part 121 and the fourth conductive part 122 is the second target length of the second ground line 12.
When the circuit board line detection system 100 further includes a third conductive connecting part 17 and a fourth conductive connecting part 18, and the third conductive connecting part 17 and the fourth conductive connecting part 18 are slidably disposed on the second ground line 12, the third conductive part 121 is disposed on the third conductive connecting part 17 and electrically connected to the second ground line 12 through the third conductive connecting part 17, and the fourth conductive part 122 is disposed on the fourth conductive connecting part 18 and electrically connected to the second ground line 12 through the fourth conductive connecting part 18, the third conductive connecting part 121 can be driven to slide by directly sliding the third conductive connecting part 17, or the fourth conductive connecting part 122 can be driven to slide by directly sliding the fourth conductive connecting part 18, or the third conductive connecting part 17 and the fourth conductive connecting part 18 can be simultaneously slid to drive the third conductive part 121 and the fourth conductive part 122 to slide, until the length of the second ground line 12 between the third conductive part 121 and the fourth conductive part 122 is adapted to the fracture length 1011 of the first radio frequency line 101, at this time, the length of the second ground line 12 between the third conductive part 121 and the fourth conductive part 122 is the second target length of the second ground line 12.
Step 207: and cutting off the other parts of the second radio frequency circuit except the first target length.
That is, the length of the second rf line 11 is cut to the first target length, so as to avoid the situation that the circuit board 10 is disconnected due to the extra second rf line 11 disposed on the circuit board 10.
Step 208: and cutting off the other parts of the second grounding circuit except the second target length.
That is, the length of the second grounding line 12 is cut to a second target length, so as to avoid the situation that the redundant second grounding line 12 is arranged on the circuit board 10 to cause the circuit board 10 to be broken.
Step 209: and welding the first conductive part and the second conductive part at the fracture position of the first radio frequency circuit.
As can be seen from the foregoing, in order to facilitate the circuit board circuit inspection system 100 to inspect the rf circuit, it is preferable to use thin conductive wires for the first conductive part 111 and the second conductive part 112, for example, the first conductive part 111 and the second conductive part 112 are directly soldered on the first rf circuit 101, and the first conductive part 111 and the second conductive part 112 are easily broken by an external force, so that the first rf circuit 101 is broken. Therefore, before the first conductive part 111 and the second conductive part 112 are soldered to the first rf line 101, the first conductive part 111 and the second conductive part 112 may be replaced by thicker wires, such as thicker wires having the same thickness as the first rf line 101, so as to improve the force-bearing capability of the first conductive part 111 and the second conductive part 112.
Since the first conductive portion 111 and the second conductive portion 112 are directly soldered on the first rf line 101, the contact area between the first conductive portion 111 and the first rf line 101 and the contact area between the second conductive portion 112 and the first rf line 101 are small, which results in poor connection stability between the first conductive portion 111 and the first rf line 101 and the second conductive portion 112, and the first conductive portion 111 and the second conductive portion 112 are easily separated from the first rf line 101. Therefore, in some embodiments, the pads 19 are soldered at one end of the first conductive portion 111 and the second conductive portion 112 to the first rf traces 101 before the circuit board trace detection system 100 is electrically connected to the circuit board 10 at the open position.
