[0002] Because QFN-packaged microwave switches have small pads and no pins, and the input, output, and power supply terminals are concentrated on the bottom electrode contact points, performance testing of such QFN-packaged microwave switches requires placing the switch on a PCB with its terminals aligned with the RF channels on the PCB to transmit RF signals. However, when testing the switch directly on a PCB, external factors such as vibration and impact may cause the switch to shift position, resulting in unstable signal transmission and affecting the entire test process. Summary of the Invention

[0003] In view of this, the purpose of this application is to propose a single-pole eight-throw microwave switch testing device to solve the problem that when the microwave switch is placed on a PCB board for testing, the microwave switch may be displaced due to external factors such as vibration and impact, thereby affecting the entire testing process.

[0018] The limit rod is connected to one of the vertical side surfaces of the vertical rod. The limit rod is used to abut against the lower surface of the second transverse plate when the vertical rod moves upward relative to the through slot, so as to limit the vertical rod from excessive upward movement and cause the slider to detach from the slide bar.

DETAILED DESCRIPTION

[0030] In order to make the objectives, technical solutions and advantages of this application more clear, this application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0031] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should have the usual meanings understood by people with ordinary skills in the field to which this application belongs.

When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0032] Based on the background, during the performance test of QFN packaged microwave switches, since the pads of QFN packaged microwave switches are small, there are no pins, and the input, output and power supply terminals are concentrated on the bottom electrode contact points, a series of precise and meticulous operating steps need to be taken during the performance test to ensure the accuracy and reliability of the test.

[0033] The concentrated layout of the bottom electrode contact points of a QFN-packaged microwave switch necessitates ensuring good electrical connection between these points and the RF path on the PCB during performance testing. However, in actual testing, we often find that placing the microwave switch directly on the PCB for testing can cause its position to shift due to external factors such as vibration and shock. This shift can affect the transmission stability and integrity of the RF signal, further impacting the accuracy and reliability of the test.

[0034] The following is combined with Figure 1-6 The embodiments of the present application will be described in detail.

[0035] like Figure 1 、 Figure 2 and Figure 3 As shown, a single-pole eight-throw microwave switch test device includes:

[0036] PCB board 1, used to provide a test circuit 11 for the microwave switch to be tested;

[0037] The crimping assembly 2 is used to fix the microwave switch under test on the PCB board 1. The crimping assembly 2 includes a vertical frame 21, a sliding structure 22, a driving structure 23, and a crimping member 24. The driving structure 23 is connected to the vertical frame 21, the crimping member 24 is connected to the sliding structure 22, and the sliding structure 22 is slidably connected to the vertical frame 21. The driving structure 23 is used to drive the sliding structure 22 to slide along the length direction of the vertical frame 21 so that the crimping member 24 crimps the microwave switch under test.

[0038] Specifically, the vertical frame 21 includes a first vertical frame 211 and a second vertical frame 212, which are positioned relative to each other. A sliding structure 22 is installed between the first and second vertical frames 211, 212. A driving structure 23 is installed on top of the first and second vertical frames 211, 212 to drive the sliding structure 22 to move along the length of the vertical frame 21. The PCB 1 is located below the crimping member 24, the microwave switch to be tested is located at the center of the PCB 1, and the microwave switch to be tested is located directly below the crimping member 24. The crimping member 24 is connected to the sliding structure 22, and the sliding structure 22 drives the crimping member 24 downward to press against the microwave switch to be tested.

[0039] In this embodiment, the vertical frame 21 is the basic structure of the crimping assembly 2, and the vertical frame 21 provides an installation position for the driving structure 23 and the sliding structure 22. The driving structure 23 drives the sliding structure 22 to slide up and down along the length direction of the vertical frame 21. The crimping part 24 is connected to the sliding structure 22. The sliding structure 22 drives the crimping part 24 to move up and down under the action of the driving structure 23. When the switch to be tested needs to be tested, the sliding structure 22 drives the crimping part 24 to move downward under the action of the driving structure 23 to press the microwave switch to be tested, so that the microwave switch to be tested is in close contact with the PCB board 1, ensuring good electrical connectivity between the microwave switch to be tested and the PCB board 1, and avoiding position displacement of the microwave switch on the PCB board 1 during the test, thereby ensuring stable signal transmission during the test.

[0040] In some embodiments, as Figure 1 and Figure 2 As shown, a distance measuring component 3 is provided between the crimping member 24 and the sliding structure 22, and the distance measuring component 3 includes:

[0041] A mounting member 31 connected between the sliding structure 22 and the crimping member 24;

[0042] a laser ranging light 32 mounted on the mounting member 31 for detecting the distance between the mounting member 31 and the microwave switch to be tested;

[0043] The display screen 33 is used to display the distance measured by the laser ranging light 32.

[0044] Specifically, mounting member 31 is a mounting block with a mounting hole 311 on one side of the mounting block near the crimping member 24. A laser rangefinder 32 is installed in this hole 311 to measure the distance between mounting member 31 and the microwave switch being tested. A display screen 33 is mounted on one of the vertical sides of the mounting block, allowing the user to easily view the distance information displayed by the laser rangefinder 32. It can also be used to display error codes or warning messages. If a problem occurs during the crimping process, such as the distance exceeding the preset range or a malfunction of the laser rangefinder 32, the display screen 33 immediately provides a prompt, helping the user quickly locate and resolve the issue. Based on the distance measured by the laser rangefinder 32, the drive assembly uses a built-in intelligent control system to precisely control the downward movement of the crimping member 24, ensuring that the crimping member 24 precisely presses against the microwave switch being tested. The intelligent control system ensures that the crimping member 24 reaches the required pressure during the pressing process, while also avoiding unnecessary damage to the microwave switch. In addition, in order to ensure the stability and reliability of the entire crimping process, the drive assembly may also be equipped with sensors and monitoring devices for real-time monitoring of various parameters in the crimping process, such as pressure, temperature, etc. These data will also be transmitted to the control system for intervention and adjustment when necessary. The control system can be controlled by a host computer control platform to facilitate users to issue operating instructions to the control system.

[0045] In addition, the crimping member 24 is in the shape of an inverted truncated cone, with a larger upper surface area and a smaller lower surface area. The upper surface of the crimping member 24 is fixedly connected to the mounting member 31 to increase the connection area between the crimping member 24 and the mounting member 31 and increase the stability of the connection. The lower surface of the crimping member 24 is adapted to the size of the microwave switch to be tested so that the crimping member 24 applies uniform pressure to the microwave switch to be tested, thereby achieving good electrical contact between the microwave switch to be tested and the PCB board 1.

[0046] In this embodiment, mounting member 31 is used to mount a laser rangefinder 32 and a display screen 33. The laser rangefinder 32 accurately measures the distance between mounting member 31 and the microwave switch under test in real time. The driver assembly precisely controls the downward movement of crimping member 24 based on the distance measured by the laser rangefinder 32, ensuring that crimping member 24 precisely contacts the microwave switch and achieves the required pressure while avoiding unnecessary damage to the switch. Display screen 33 allows the user to observe the distance information displayed by the laser rangefinder 32, making it easier to determine whether the laser rangefinder 32 is functioning properly. In summary, the distancefinder assembly 3 enables more accurate control of the crimping process, improving its precision and intuitiveness.

[0047] In some embodiments, as Figure 3 and Figure 4As shown, a test circuit 11 is provided on the PCB board 1, and the test circuit 11 includes multiple RF lines 111. One end of each RF line 111 is connected to a terminal of the microwave switch to be tested, and the other end extends to an edge of the PCB board 1 to connect to an external RF module.

[0048] In addition, the test circuit 11 also includes a control circuit 112. One end of the control circuit 112 is connected to the terminal of the microwave switch under test, and the other end extends to the edge of the PCB board 1 where the RF circuit 111 is not provided, so as to connect to an external control module. The PCB board 1 is a regular polygon, and one end of each of the RF circuits 111 extends to the midpoint of a different edge of the PCB board 1.

[0049] Specifically, nine RF lines 111 can be provided to respectively connect to the nine RF terminals of the single-pole eight-throw microwave switch. The PCB board 1 can be correspondingly provided in a decagonal shape. One end of each of the RF lines 111 is correspondingly connected to a terminal of the microwave switch to be tested, and the other end extends to the midpoint of an edge of the PCB board 1 to ensure that the length of each RF line 111 is relatively uniform, thereby reducing the signal loss difference caused by the difference in line length. In addition, only one RF line 111 is provided on each edge of the PCB board 1, and a control line 112 is provided on the remaining edge. This design helps to reduce signal interference between different lines and improve the accuracy of the test.

[0050] In this embodiment, the PCB board 1 is a regular polygon, and one end of the RF circuit 111 on the PCB board 1 is connected to the terminal of the microwave switch to be tested, and the other end extends to the center position of different edges of the PCB board 1. This design ensures that the length of each RF circuit 111 is relatively uniform, reduces the signal loss difference caused by the difference in circuit length, and avoids RF signal crosstalk between different RF circuits 111, thereby ensuring the accuracy of the test. One end of the control circuit 112 is connected to the terminal of the microwave switch to be tested, and the other end extends to the edge of the PCB board 1 where the RF circuit 111 is not provided. This design prevents RF signals from interfering with control signals, thereby ensuring the normal operation of the test process.

[0051] In some embodiments, as Figure 3 and Figure 4 As shown, a single-pole eight-throw microwave switch testing device also includes a base 4 adapted to the PCB board 1 for placing the PCB board 1. The base 4 is provided with a plurality of slots 41, and the PCB board 1 is connected to the external module through the slots 41.

[0052] Specifically, the PCB board 1 is a regular polygon, and the base 4 is a regular polygon that matches the PCB board 1. The upper surface of the base 4 abuts the lower surface of the PCB board 1, and the PCB board 1 and the base 4 can be fixed by fixing screws. The slots 41 include a first slot 411 and a second slot 412. Each vertical side of the base 4 is provided with multiple first slots 411. Each edge of the upper surface of the base 4 is provided with a second slot 412 downwardly extending. The second slots 412 are connected to the first slots 411 located opposite each other. SMA connectors can be installed in the first slots 411 and the second slots 412. The RF circuit 111 and the control circuit 112 on the PCB board 1 are connected to the external module via the SMA connector.

[0053] In this embodiment, the PCB 1 is designed as a regular polygon, and the base 4 is also designed to match it. This design ensures that the PCB 1 can be securely placed on the base 4, avoiding instability caused by shape mismatch. The first slot 411 and the second slot 412 provide connection locations between each test circuit 11 and an external module. SMA connectors can be installed in the first slot 411 and the second slot 412 to connect the test circuit 11 on the PCB 1 with the external module, ensuring stable testing.

[0054] In some embodiments, as Figure 1 As shown, the vertical frame 21 includes a first vertical frame 211 and a second vertical frame 212, which are arranged in opposite positions. Slide bars 5 are provided on the opposite sides of the first vertical frame 211 and the second vertical frame 212. The sliding structure 22 includes a first horizontal plate 221 and sliders 222 respectively provided at both ends of the first horizontal plate 221. The sliders 222 are slidably connected to the slide bars 5.

[0055] Specifically, the bottoms of the first and second vertical frames 211, 212 are designed with adjustable ground fixing devices, such as screw anchors or expansion plugs, to ensure that the vertical frames 21 are firmly mounted on the ground and mitigate the effects of uneven surfaces or vibrations. The sliders 222 can be made of wear-resistant, low-friction materials, and the surface of the slider bar 5 can be coated with a lubricant or a self-lubricating material to reduce sliding resistance and enhance smoothness.

[0056] In this embodiment, the first vertical frame 211 and the second vertical frame 212 are positioned opposite each other, connected by a sliding structure 22 and secured by an external connecting structure, forming a stable support structure that provides stable support for the structure loaded thereon. The first horizontal plate 221 provides a mounting position for the mounting member 31, which indirectly provides a mounting position for the crimping member 24. The slider structure guides the crimping member 24 in its vertical movement, preventing it from shifting during its vertical movement, which could hinder effective securing of the test switch under test and affect test results.

[0057] In some embodiments, as Figure 1 As shown, the crimping assembly 2 further includes a limiting structure 25 for limiting the upward movement of the crimping member 24, and the limiting structure 25 includes a second transverse plate 251, a vertical rod 252 and a limiting rod 253; wherein,

[0058] The second horizontal plate 251 is connected between the first vertical frame 211 and the second vertical frame 212 and is provided with a through slot 2511 thereon; the vertical rod 252 is connected to the upper surface of the first horizontal plate 221 and passes through the through slot 2511;

[0059] The limiting rod 253 is connected to one of the vertical side surfaces of the vertical rod 252. The limiting rod 253 is used to press against the lower surface of the second horizontal plate 251 when the vertical rod 252 moves upward relative to the through groove 2511, so as to limit the vertical rod 252 from excessively moving upward and causing the slider 222 to detach from the slide bar 5.

[0060] In this embodiment, the second transverse plate 251 connects the first vertical frame 211 and the second vertical frame 212, thereby increasing the connectivity between the first vertical frame 211 and the second vertical frame 212, thereby increasing the stability of the first vertical frame 211 and the second vertical frame 212. The second transverse plate 251 is provided with a through-slot 2511. The vertical rod 252 is connected to the upper surface of the first transverse plate 221 and passes through the through-slot 2511. The limiting rod 253 is connected to one of the vertical side surfaces of the vertical rod 252. The limiting rod 253 is used to abut against the lower surface of the second transverse plate 251 when the vertical rod 252 moves upward relative to the through-slot 2511. The above-mentioned limiting structure 25 limits the upward movement range of the vertical rod 252, preventing the slider 222 from falling off the slide bar 5 due to excessive upward movement of the vertical rod 252 during upward movement, thereby ensuring the stability and reliability of the sliding structure 22.

[0061] In some embodiments, as Figure 1 and Figure 5 As shown, both the first vertical rod 252 and the second vertical rod 252 are provided with a limited long groove 2111, and the two ends of the second cross plate 251 are threadedly connected with bolts 6, and the bolts 6 respectively pass through the limited long grooves 2111 on the first vertical rod 252 and the second vertical rod 252, and fix the second cross plate 251 by abutting the first vertical rod 252 and the second vertical rod 252. The up and down movement of the second cross plate 251 in the limited long groove 2111 is controlled by adjusting the tightness of the bolts 6.

[0062] Specifically, a plurality of limiting long grooves 2111 may be provided on the first vertical rod 252 and the second vertical rod 252, and a plurality of bolts 6 may be provided at both ends of the second horizontal plate 251. The bolts 6 correspond one-to-one to the limiting long grooves 2111, and the bolts 6 abut against the first vertical rod 252 and the second vertical rod 252 to fix the second horizontal plate 251. The second horizontal plate 251 is fixed between the first vertical rod 252 and the second vertical rod 252 by a plurality of fixing bolts 6, thereby enhancing the stability of the second horizontal plate 251.

[0063] In this embodiment, the second cross plate 251 can be moved up and down according to actual needs. When more operating space is needed, the second cross plate 251 is moved up to allow the crimping member 24 to move further up, leaving more space for operation. The design of the bolt 6 connecting the second cross plate 251 makes the installation and removal of the second cross plate 251 more convenient. When the position of the second cross plate 251 needs to be adjusted, the second cross plate 251 can be easily removed by simply loosening the bolt 6, reducing maintenance costs and time costs.

[0064] In some embodiments, the driving structure 23 is a hydraulic cylinder structure or a pneumatic cylinder structure.

[0065] Specifically, the driving structure 23 includes a third horizontal plate and a driving assembly. The driving assembly is a hydraulic cylinder assembly or a cylinder assembly. The third horizontal plate is installed on the top of the first vertical rod 252 and the second vertical frame 212. The driving assembly is installed on the third horizontal plate. The output shaft of the driving assembly passes through the third horizontal plate and is connected to the top of the vertical rod 252 to drive the vertical rod 252, the sliding structure 22, the mounting seat and the crimping part 24 to move up and down.

[0066] In this embodiment, the driving structure 23 is a hydraulic cylinder structure or a cylinder structure. Regardless of whether it is a hydraulic cylinder structure or a cylinder structure, the driving structure 23 has a strong driving force and can stably drive the vertical rod 252, the sliding structure 22, the mounting seat and the crimping part 24 to move up and down.

[0067] In some embodiments, as Figure 6 As shown, the PCB board 1 is provided with a positioning plate 7 connected to the upper surface of the PCB board 1. The positioning plate 7 is provided with a positioning groove 71 penetrating the positioning plate 7 for accommodating the microwave switch to be tested. The positioning plate 7 is also provided with a reserved hole 72 connected to the positioning groove 71 to facilitate removing the microwave switch to be tested from the positioning groove 71.

[0068] Specifically, the PCB board 1 is connected to the positioning plate 7 by bolts, which facilitates the installation and removal of the positioning plate 7.

[0069] In this embodiment, a positioning groove 71 is provided on the positioning plate 7, and the microwave switch to be tested is placed in the positioning groove 71, thereby accurately placing the microwave switch to be tested on the solder pad of the PCB board 1. Then, in conjunction with the crimping assembly 2, good electrical contact is achieved between the PCB board 1 and the microwave switch to be tested. The provision of the reserved hole 72 facilitates the tester to remove the microwave switch to be tested using tweezers.

[0070] In summary, the vertical frame 21 in the present invention is the basic structure of the crimping assembly 2, and the vertical frame 21 provides an installation position for the driving structure 23 and the sliding structure 22. The driving structure 23 drives the sliding structure 22 to slide up and down along the length of the vertical frame 21. The crimping member 24 is fixedly connected to the sliding structure 22. The sliding structure 22 drives the crimping member 24 to move up and down under the action of the driving structure 23. When it is necessary to test the switch to be tested, the sliding structure 22 drives the crimping member 24 to move downward under the action of the driving structure 23 to press the switch to be tested, so that the switch to be tested is in close contact with the PCB board 1, ensuring good electrical connectivity between the microwave switch and the PCB board 1, and preventing the microwave switch from shifting on the PCB board 1 during the test, thereby ensuring stable signal transmission during the test process;

[0071] The mounting member 31 of the present invention is used to mount a laser rangefinder light 32 and a display screen 33. The laser rangefinder light 32 can accurately measure the distance between the mounting member 31 and the microwave switch to be tested in real time. The driving assembly precisely controls the downward movement of the crimping member 24 based on the distance measured by the laser rangefinder light 32, ensuring that the crimping member 24 is precisely crimped onto the microwave switch. This ensures that the crimping member 24 achieves the required pressure during the crimping process, while avoiding unnecessary damage to the microwave switch.

[0072] The PCB board 1 in the present invention is a regular polygon, and one end of the RF circuit 111 on the PCB board 1 is connected to the terminal of the microwave switch to be tested, and the other end extends to the center position of different edges of the PCB board 1. This design ensures that the length of each RF circuit 111 is relatively uniform, reducing the signal loss caused by the difference in circuit length and avoiding RF signal crosstalk between different RF circuits 111, thereby ensuring the accuracy of the test. One end of the control circuit 112 is connected to the terminal of the microwave switch to be tested, and the other end extends to the edge of the PCB board 1 where the RF circuit 111 is not provided. This design prevents RF signals from interfering with control signals, thereby ensuring the normal operation of the test process.
