Abstract
Description
Technical Field
[0001] This application relates to the technical field of equipment debugging, and more specifically, to a circuit impedance matching debugging clip. Background Art
[0002] With the rapid development of communication technologies, there are more and more new communication electronic products, and the application of PCBs (Printed Circuit Boards) is becoming more and more extensive. However, affected by the PCB manufacturing process, SMT (Surface Mounted Technology) chip mounting process, the material of the PCB, and the properties of the components and devices, the impedance of the PCB frequency band after SMT chip mounting often changes, resulting in low energy efficiency when the PCB is in use.
[0003] In order to improve the energy efficiency of the PCB during use, it is necessary to perform matching debugging to make the impedance of the PCB frequency band after SMT chip mounting reach the required range. The prior art usually uses a hot air gun or a soldering iron to heat the connection points between the inductors, capacitors, and resistors in the matching circuit and the PCB to remove the inductors, capacitors, and resistors in the matching circuit, and replace them with other devices until the impedance of the PCB frequency band after SMT chip mounting reaches the required range. However, repeated soldering will cause changes in the impedance of the PCB and electronic devices, changing the existing impedance characteristics of the PCB and electronic devices, thereby increasing the matching difficulty. In addition, with the development of communication technologies, the packaging of electronic devices is getting smaller and the PCB layout is getting denser, which also increases the difficulty of matching debugging and component replacement. When replacing electronic devices, it is easy to move other devices, so frequent component replacement increases the risk of damaged boards and raises the R & D cost. Summary of the Utility Model

[0028] Please refer to Figure 1 and Figure 2 , an embodiment of the present application provides a circuit impedance matching debugging clip 100, including: an electronic regulator 110, and two first conductive sheets 120 respectively electrically connected to the input end and the output end of the electronic regulator 110. The ends of the two first conductive sheets 120 away from the electronic regulator 110 are respectively used to abut against two pads of an electronic device on a matching circuit, and the electronic regulator 110 is used to adjust its own capacitance value or inductance value.
[0029] Specifically, the electronic regulator 110 can implement a capacitance function or an inductance function, that is, it is equivalent to a capacitor or an inductor. When the electronic regulator 110 implements the capacitance function, the electronic regulator 110 can adjust its own capacitance value; when the electronic regulator 110 implements the inductance function, the electronic regulator 110 can adjust its own inductance value. The electronic regulator 110 has an input terminal and an output terminal, and first conductive sheets 120 are respectively connected to the input terminal and the output terminal. The electronic regulator 110 can be connected to the matching circuit through the two first conductive sheets 120.
[0030] During the impedance matching debugging process, the two first conductive sheets 120 of the circuit impedance matching debugging clip 100 are respectively abutted against two pads of the electronic device on the matching circuit, so that the electronic regulator 110 is connected to the matching circuit. Adjust the capacitance value or inductance value of the electronic regulator 110 until the impedance of the PCB frequency band after SMT component mounting reaches the required range. Then, remove the circuit impedance matching debugging clip 100, provide another electronic device with the same capacitance value or inductance value as the electronic regulator 110 at this time, and connect the electronic device to the matching circuit, so that the impedance of the PCB frequency band after SMT component mounting can be maintained within the required range.
[0031] The above-mentioned circuit impedance matching debugging clip 100 comes with an electronic regulator 110, and the electronic regulator 110 can be connected to the matching circuit through the first conductive sheet 120. During impedance matching debugging, there is no need to use a hot air gun or soldering iron to heat and remove the original electronic device and then replace it with other electronic devices, thereby reducing the matching difficulty. The above-mentioned circuit impedance matching debugging clip 100 can be further calibrated after being measured by a bridge to ensure accuracy.
[0032] Optionally, please refer to Figure 3 , the electronic regulator 110 includes a housing 111, a switch 112, a capacitance regulator 113 and an inductance regulator 114 arranged in the housing 111. The switch 112 is electrically connected to the capacitance regulator 113 or the inductance regulator 114, and the switch 112 is also electrically connected to the two first conductive sheets 120. The capacitance regulator 113 is used to adjust its own capacitance value, and the inductance regulator 114 is used to adjust its own inductance value.
[0033] When the switch 112 is connected to the capacitance regulator 113, the input terminal and the output terminal of the capacitance regulator 113 are respectively electrically connected to the two first conductive sheets 120. At this time, the electronic regulator 110 can implement the capacitance function and is equivalent to a capacitor. After the capacitance regulator 113 is connected to the matching circuit, by adjusting its own capacitance value, the impedance of the PCB frequency band after SMT component mounting reaches the required range.
[0034] When the switch 112 is connected to the inductance regulator 114, the input terminal and the output terminal of the inductance regulator 114 are electrically connected to two first conductive sheets 120 respectively. At this time, the electronic regulator 110 can realize the inductance function and is equivalent to an inductor. After the inductance regulator 114 is connected to the matching circuit, by adjusting its own inductance value, the impedance of the PCB frequency band passing through the SMT component mounting reaches the required range.
[0035] During the impedance matching debugging process, the user can select to connect the capacitance regulator 113 or the inductance regulator 114 to the matching circuit by adjusting the switch 112. The impedance of the PCB frequency band passing through the SMT component mounting can also reach the required range by adjusting the capacitance value of the capacitance regulator 113 or the inductance value of the inductance regulator 114.
[0036] It can be understood that when the circuit impedance matching debugging clamp 100 is not used, the switch 112 can neither be electrically connected to the capacitance regulator 113 nor to the inductance regulator 114.
[0037] Optionally, the switch 112 includes two second conductive sheets 1121. One end of one second conductive sheet 1121 is electrically connected to one first conductive sheet 120, and the other end is electrically connected to the input terminal of the capacitance regulator 113 or the input terminal of the inductance regulator 114. One end of the other second conductive sheet 1121 is electrically connected to the other first conductive sheet 120, and the other end is electrically connected to the output terminal of the capacitance regulator 113 or the output terminal of the inductance regulator 114.
[0038] When the two second conductive sheets 1121 are respectively connected to the input terminal and the output terminal of the capacitance regulator 113, the capacitance regulator 113 is connected to the matching circuit; when the two second conductive sheets 1121 are respectively connected to the input terminal and the output terminal of the inductance regulator 114, the inductance regulator 114 is connected to the matching circuit.
[0039] Optionally, a touch screen is provided on the outside of the housing 111. The touch screen is electrically connected to the switch 112, the capacitance regulator 113, and the inductance regulator 114 respectively. The touch screen is used to control the connection and opening / closing of the switch 112, the capacitance value of the capacitance regulator 113, and the inductance value of the inductance regulator 114.
[0040] The touch detection device provided on the touch screen can sense the touch position of the user on the screen and transmit the touch position information to the internal controller. After receiving the touch position information, the controller converts it into contact coordinates, judges the meaning of the touch, and sends it to the programmable logic controller. The programmable logic controller issues an instruction to the controller according to the meaning of the touch information, and the controller executes the instruction after receiving it.
[0041] The instructions sent by the programmable logic controller to the controller at least include: disconnecting switch 112, connecting switch 112 to the capacitor regulator 113, connecting switch 112 to the inductor regulator 114, adjusting the capacitance value of the capacitor regulator 113, and adjusting the inductance value of the inductor regulator 114.
[0042] Optionally, a plurality of mechanical buttons are provided on the outside of the housing 111. The plurality of mechanical buttons are electrically connected to the switch 112, the capacitor regulator 113, and the inductor regulator 114 respectively. The mechanical buttons are used to control the connection, opening, and closing of the switch 112, the capacitance value of the capacitor regulator 113, or the inductance value of the inductor regulator 114.
[0043] The user presses buttons with different functions to achieve operations such as disconnecting switch 112, connecting switch 112 to the capacitor regulator 113, connecting switch 112 to the inductor regulator 114, adjusting the capacitance value of the capacitor regulator 113, and adjusting the inductance value of the inductor regulator 114.
[0044] Optionally, please refer to Figure 1 and Figure 2 , a conductive contact 121 is formed at one end of the first conductive sheet 120 away from the electronic regulator 110.
[0045] The first conductive sheet 120 presses on the pad through the conductive contact 121. The volume of the conductive contact 121 is small. Even if the space around the electronic device is small or the area of the pad is small, the conductive contact 121 can still achieve abutment against the pad.
[0046] Optionally, the material of the first conductive sheet 120 is metal.
[0047] The metal has a relatively high hardness and can press the pad well, thereby achieving a stable electrical connection between the electronic regulator 110 and the PCB.
[0048] Optionally, an insulating layer 115 is wrapped around the outside of the first conductive sheet 120, and the conductive contact 121 is exposed from the insulating layer 115.
[0049] The insulating layer 115 isolates the first conductive sheet 120 from the outside world, and only exposes the conductive contact 121 to abut against the pad of the electronic device on the matching circuit. Such a setting can prevent the first conductive sheet 120 from accidentally contacting other electronic devices or other pads, causing short circuits or other failures.
[0050] Optionally, the material of the insulating layer 115 is elastic plastic.
[0051] Selecting elastic plastic as the material of the insulating layer 115 can make the insulating layer 115 have sufficient elasticity to adapt to the abutment and pressing of electronic devices with different packages.
[0052] As the PCB layout becomes more and more dense, the spacing between each electronic component on the PCB is small. In order to enable the conductive contact 121 to smoothly abut against the pad of the electronic device on the matching circuit, optionally, the width B of the insulating layer gradually decreases from the electronic regulator 110 to the conductive contact 121. Thus, the volume of the insulating layer 115 around the conductive contact 121 is small, so as to extend into a smaller space.
[0053] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
