Description

Technical Field

[0001] The invention relates to the technical field of electromagnetic variable testing, and in particular to an ultra-short probe connector based on electromagnetic compatibility. Background Art

[0002] With the rapid development of technologies such as 5G and automotive radar, the operating frequency of electronic devices continues to increase, especially in the submillimeter wave and terahertz frequency bands. This trend not only promotes technological innovation in the fields of communications, sensing and imaging, but also poses higher challenges to chip testing technology. In this high-frequency environment, traditional test methods and connector designs face many problems such as signal attenuation, noise interference and electromagnetic compatibility, which directly affect the electrical performance verification and reliability evaluation of the chip. Therefore, the development of high-performance test connectors and technologies that meet the needs of emerging frequency bands has become an urgent task in the current electronic testing field to ensure that accurate and stable test results can be obtained in complex high-frequency test environments.

[0003] When the wafer probe station tests the electrical performance of the chip, a probe test component is usually connected between the probe fixture and the test instrument. The two ends of the component are generally a common connector and a probe connector. When the test instrument and the probe fixture are far apart horizontally, the cable connected by the traditional right-angle 90° connector can be directly connected to the probe fixture; when the test instrument and the probe fixture are very close horizontally, the cable connected by the ordinary right-angle 90° connector cannot be directly connected to the probe fixture. Since there is a height and angle difference between the test instrument and the probe fixture platform, if the cable is bent directly, the probe component will be squeezed and deformed, which will cause damage over time and eventually affect the probe test results. Summary of the invention

[0004] To this end, the present invention provides an ultra-short probe connector based on electromagnetic compatibility to overcome the problems in the prior art of signal loss caused by cable bending due to connector angle fixing and inaccurate test results caused by probe component damage.

[0061] Please continue reading Figure 2 As shown, it is a schematic diagram of each module in the groove of this embodiment;

[0062] This embodiment provides an ultra-short probe connector based on electromagnetic compatibility, including:

[0063] The carrier includes an input port 2 for connecting the test equipment through the tail pipe 4, an output port 3 for connecting the probe assembly, and a groove 10. The groove 10 is provided with a data acquisition module 1, a determination module 5, a first selection module 6, a second selection module 7, an adjustment module 8, and a correction module 9. The tail pipe 4 is connected to the input port 2 at a preset angle to transmit a radio frequency signal.

[0064] The data acquisition module 1 is used to respectively collect the real-time current and real-time magnetic flux at the input port 2 and the output port 3 during the chip test, and the real-time height difference between the input port 2 and the test equipment;

[0065] The determination module 5 is connected to the data acquisition module 1 and is used to determine the abnormal result of the tail pipe according to the real-time current or the real-time magnetic flux;

[0066] The first selection module 6 is connected to the determination module 5 and the data acquisition module 1 respectively, and is used to select a first adjustment mode based on the real-time height difference and the real-time current adjustment, or select a second adjustment mode based on the real-time height difference and the real-time magnetic flux adjustment according to the tail pipe abnormality result, the real-time current at the input port, and a preset standard current variation range;

[0067] The second selection module 7 is connected to the first selection module 6, and is used to select a third adjustment mode based on the real-time height difference, the real-time current and the real-time magnetic flux adjustment according to the number of times the first adjustment mode is selected within a preset selection time, the number of times the second adjustment mode is selected and a preset standard selection ratio;

[0068] The adjustment module 8 is connected to the first selection module 6, the second selection module 7 and the tail pipe 4 respectively, and is used to adjust the preset angle according to the first adjustment mode, the second adjustment mode, or the third adjustment mode to form an adjustment angle;

[0069] The correction module 9 is connected to the adjustment module 8 and the tail pipe 4 respectively, and is used to correct the preset angle according to the number of the adjustment angles within a preset correction time and a preset standard number fluctuation value.

[0070] The preset angle is the initial connection angle between the tail pipe and the test equipment, which depends on the test requirements and equipment connection requirements. It is usually set between 10 degrees and 30 degrees. In this embodiment, it is set to 20 degrees, which can ensure connection stability and reduce signal interference.

[0071] The preset standard current variation range is used to determine the variation range of abnormal current, which depends on the electromagnetic compatibility performance of the equipment and is usually set between ±5% and ±15%. In this embodiment, it is set to ±10% to identify abnormal current fluctuations while ensuring stability.

[0072] The preset selection duration is the time period for adjusting the mode selection, which depends on the periodicity of the test process and is usually set between 5 seconds and 10 seconds. In this embodiment, it is 8 seconds, which is conducive to maintaining the flexibility and responsiveness of the adjustment.

[0073] The preset standard selection ratio is used to set the selection frequency ratio of the first and second adjustment modes, which depends on the adjustment strategy and is usually set between 40% and 60%. In this embodiment, it is set to 50% to balance the usage rate of the two adjustment modes and improve the adjustment accuracy.

[0074] The preset correction duration is the time period for judging the stability of the adjustment angle and making corrections. It depends on the correction requirements and the rate of environmental change. It is usually set between 15 and 30 seconds. In this embodiment, it is set to 20 seconds to ensure stable adjustment accuracy and a fast-response correction mechanism.

[0075] The data acquisition module is used to obtain the current, magnetic flux and height difference data during the chip test in real time. The judgment module analyzes the real-time current or magnetic flux to detect whether the tail pipe is abnormal. In the case of an abnormal tail pipe, the first selection module selects the appropriate adjustment mode according to the abnormality type and the current change degree to ensure system stability. The second selection module intelligently switches to the third adjustment mode according to the number of selections of each adjustment mode and the proportion of the preset standard within the adjustment time to more accurately adjust the tail pipe angle. The adjustment module adjusts the tail pipe angle according to the selected adjustment mode, and corrects the angle according to the quantity fluctuation value under the monitoring of the correction module to achieve a highly consistent electromagnetic compatibility effect.

[0076] Through real-time data collection and tail pipe abnormality judgment functions, it can quickly identify and respond to current or magnetic flux anomalies and improve system stability. The dynamic multi-mode adjustment mechanism realizes automatic switching while adapting to real-time height difference, current and magnetic flux, effectively optimizing the tail pipe angle and reducing electromagnetic interference. The correction module monitors and corrects the fluctuation value of the adjustment angle in real time to ensure adjustment accuracy, so that the probe connector can maintain high compatibility and consistency under different test conditions, thereby greatly improving the accuracy of chip testing and the service life of the connector, and effectively solving the problem of inaccurate test results caused by signal loss caused by cable bending due to fixed connector angle and damage to probe components.

[0077] Please continue reading Figure 3 As shown, it is a determination logic diagram of the determination module of this embodiment for determining the abnormal type;

[0078] Specifically, the determination module includes:

[0079] a deviation calculation unit, used for calculating the relative deviation between the real-time current of the input port and the real-time current at the output port to obtain the real-time current deviation, and for calculating the relative deviation between the real-time magnetic flux of the input port and the real-time magnetic flux at the output port to obtain the real-time magnetic flux deviation;

[0080] a consistency calculation unit connected to the deviation calculation unit, for calculating a relative deviation between the real-time current deviation and the real-time magnetic flux deviation to form a consistency;

[0081] The abnormality determination unit is connected to the consistency calculation unit, and is used to determine the abnormality type as tail pipe angle abnormality according to the comparison result that the consistency is greater than the preset standard consistency, so as to form a tail pipe abnormality result.

[0082] The preset standard consistency is a reference value for determining tail pipe angle abnormalities, and is used to determine the relative consistency of real-time current deviation and real-time magnetic flux deviation. The consistency value depends on factors such as the test environment and equipment accuracy, and is usually set between 0.8 and 0.95. In this embodiment, it is set to 0.9, which can balance the sensitivity and stability of abnormality judgment, so that the system can accurately detect tail pipe angle abnormalities while reducing false alarms, thereby improving the reliability and accuracy of test results.

[0083] First, the deviation calculation unit calculates the relative deviation of the real-time current and magnetic flux of the input port and the output port to obtain the real-time current deviation and the real-time magnetic flux deviation; then, the consistency calculation unit calculates the relative deviation of the two deviations to form the consistency; finally, the abnormality judgment unit judges whether the tail pipe angle is abnormal according to whether the consistency exceeds the preset standard consistency value. If it exceeds, it is judged that the tail pipe angle is abnormal, forming a tail pipe abnormality result.

[0084] By calculating the current and magnetic flux deviations and their consistency, abnormal angle conditions can be quickly identified.

[0085] Please continue reading Figure 4 As shown, it is a decision logic diagram of the first selection module selecting the first adjustment mode in this embodiment;

[0086] Specifically, the first selection module includes:

[0087] A calculation start unit, used to start a change degree calculation unit according to the tail pipe abnormality result;

[0088] The change degree calculation unit is connected to the calculation start unit and is used to calculate the change speed of the real-time current at adjacent moments to form the current change degree;

[0089] A first selection unit is connected to the variation calculation unit and is used for selecting the first adjustment mode when the current variation is greater than a maximum value of the preset standard current variation range.

[0090] The first selection module, triggered by the abnormal result of the tail pipe, starts the change degree calculation unit through the calculation start unit, further calculates the change speed of the real-time current at adjacent moments, and forms the current change degree. Then, the first selection unit compares the current change degree with the maximum value of the preset standard current change degree range, and when the current change degree exceeds the range, selects the first adjustment mode for real-time adjustment.

[0091] By dynamically monitoring real-time current changes, the system can quickly determine abnormal conditions and automatically select the most suitable adjustment mode to ensure the stability and adaptability of the system in a high-precision test environment.

[0092] Specifically, the first selection unit is further configured to select the second adjustment mode when the current variation is smaller than a minimum value of the preset standard current variation range.

[0093] The first selection module starts the change calculation unit through the calculation start unit, calculates the change speed of the real-time current, and forms the current change. Subsequently, the first selection unit compares the current change with the preset standard current change range. When the current change exceeds the maximum value, the first adjustment mode is selected; when the current change is lower than the minimum value, the second adjustment mode is selected, thereby achieving accurate response to different abnormalities.

[0094] By adding the determination of the current variation being lower than the standard range, the system can flexibly switch the adjustment mode under different abnormal conditions.

[0095] Specifically, the second selection module includes:

[0096] a ratio calculation unit, used for calculating the ratio of the number of times the first adjustment mode is selected to the number of times the second adjustment mode is selected, to form a selection ratio;

[0097] A second selection unit is connected to the proportion calculation unit and is used to select the third adjustment mode according to the selection proportion and the preset standard selection proportion.

[0098] The second selection module calculates the selection ratio of the first adjustment mode and the second adjustment mode through the ratio calculation unit to form a selection ratio. Then, the second selection unit compares this selection ratio with the preset standard selection ratio. When the selection ratio reaches the preset standard selection ratio, the system selects the third adjustment mode, thereby achieving a more accurate adjustment strategy in multiple selections.

[0099] By introducing the calculation and comparison of the selection proportions, the second selection module can dynamically adjust the system operation mode according to the selection frequencies of different adjustment modes.

[0100] Specifically, the second selection unit includes:

[0101] A difference calculation subunit, used for calculating the absolute value of the difference between the selection proportion and the preset standard selection proportion to form a proportion difference;

[0102] The second selection subunit is connected to the difference calculation subunit, and is used for selecting the third adjustment mode when the proportion difference is greater than a preset standard proportion difference.

[0103] The preset standard ratio difference is used to evaluate the maximum deviation allowed between the selected ratio and the standard ratio, which depends on the stability requirements of the system and the complexity of the working environment. It is generally set between 0.05 and 0.1 to adapt to different operating conditions. In this embodiment, it is set to 0.05, which helps to ensure that the system can still effectively maintain the accuracy and stability of the adjustment strategy in the face of slight fluctuations, thereby improving the overall performance.

[0104] The second selection unit calculates the absolute value of the difference between the current selection ratio and the preset standard selection ratio through the difference calculation subunit to form a ratio difference. Then, the second selection subunit compares the ratio difference with the preset standard ratio difference. When the ratio difference exceeds the preset standard ratio difference, the system automatically selects the third adjustment mode to deal with the frequently occurring selection ratio deviation.

[0105] By monitoring the difference between the selected ratio and the preset standard selected ratio, the system is more flexible in the selection of adjustment modes. When the difference exceeds the preset range, the system switches to the third adjustment mode to quickly respond to potential unstable factors.

[0106] Specifically, the adjustment module includes:

[0107] A first calculation unit, configured to calculate a first adjustment angle value according to the first adjustment mode, the real-time height difference, the real-time current, a preset standard current, a preset standard height, a preset height coefficient, and a preset current coefficient;

[0108] a first adjustment unit connected to the first calculation unit, and configured to adjust the preset angle according to the first adjustment angle amount to form an adjustment angle;

[0109] A second calculation unit, configured to calculate a second adjustment angle value according to the second adjustment mode, the real-time height difference, the real-time magnetic flux, a preset standard magnetic flux, the preset standard height, a preset second height coefficient, and a preset magnetic flux coefficient;

[0110] The second adjustment unit is connected to the second calculation unit and is used for adjusting the preset angle according to the second adjustment angle amount to form an adjustment angle.

[0111] The first adjustment angle value and the second adjustment angle value are both calculated by weighted summation.

[0112] The preset standard current refers to the ideal current value that the input port should reach under normal working conditions, which depends on the design and test requirements of the device and is usually set between 0.1 A and 1 A. In this embodiment, it is set to 0.5 A, which can ensure the stability and reliability of the device under normal working conditions.

[0113] The preset standard height refers to the ideal height difference between the input port and the test device, which depends on the design and functional requirements of the probe connector and is usually set between 5mm and 20mm. In this embodiment, it is set to 10mm, which can ensure that the connector can be accurately aligned during the test to avoid errors.

[0114] The preset height coefficient is a coefficient used to adjust the effect of the real-time height difference on the preset angle, and depends on the specific application scenario and system design, and is usually set between 0.5 and 2. In this embodiment, it is set to 1.0 to ensure that the effect of the height difference can be reasonably reflected in actual applications.

[0115] The preset current coefficient is a coefficient used to adjust the effect of the real-time current on the preset angle. It usually depends on the current response characteristics of the system and is set in a range of 0.5 to 3. In this embodiment, the preset current coefficient is set to 1.5 so that the preset angle can be effectively adjusted when the current changes, thereby improving the stability of the system.

[0116] The preset second height coefficient is a coefficient used to adjust the second adjustment angle value calculated in the second adjustment mode. It depends on the actual test environment, equipment characteristics and design requirements. It is usually set between 0.1 and 1.0. In this embodiment, it is set to 0.5 to balance the impact of the height difference on the magnetic flux and ensure system stability.

[0117] The preset standard magnetic flux refers to the ideal magnetic flux value that the output port should reach under normal working conditions. It usually depends on the design and test requirements of the device and is usually set between 0.01Wb and 0.1Wb. In this embodiment, it is set to 0.05Wb to ensure that the device can operate under predetermined conditions and maintain electromagnetic compatibility.

[0118] The preset magnetic flux coefficient is a coefficient used to adjust the effect of the real-time magnetic flux on the preset angle, which depends on the magnetic field response characteristics of the device and is usually set between 0.5 and 3. In this embodiment, it is set to 1.2 to ensure that the preset angle can be reasonably adjusted when the magnetic flux changes, thereby optimizing the device performance.

[0119] The adjustment module calculates the adjustment angle amount based on the real-time height difference, the real-time current and the magnetic flux through the first calculation unit and the second calculation unit respectively. The first adjustment unit adjusts the preset angle according to the first adjustment angle amount to form a new adjustment angle; the second adjustment unit adjusts the preset angle according to the second adjustment angle amount to further optimize the angle setting, thereby improving the working stability and electromagnetic compatibility of the connector.

[0120] Through the flexible first and second adjustment modes, the module can respond promptly according to different real-time current and magnetic flux changes, thereby effectively reducing test errors caused by improper angles.

[0121] Specifically, the adjustment module also includes:

[0122] a third calculation unit, configured to calculate a third adjustment angle value according to the third adjustment mode, the real-time height difference, the real-time current, the real-time magnetic flux, the preset standard magnetic flux, the preset standard current, the preset standard height, a preset third height coefficient, a preset third current coefficient, and a preset third magnetic flux coefficient;

[0123] A third adjustment unit is connected to the third calculation unit and is used to adjust the preset angle according to the third adjustment angle amount to form an adjustment angle.

[0124] The third adjustment angle is calculated by weighted summation.

[0125] The preset third height coefficient is a weight factor used to adjust the preset angle, which depends on the degree of influence of height changes on connector performance in specific application scenarios, and is usually set between 0.1 and 1.0. In this embodiment, it is set to 0.5, which can appropriately pay attention to height changes during the adjustment process, thereby ensuring that the system can effectively cope with work under different height conditions and improve the stability and adaptability of the connector.

[0126] The preset third current coefficient is a weight factor for adjusting the preset angle, which indicates the degree of influence of current changes on the adjustment angle. It depends on the impact of the current on the performance of the probe connector and signal transmission. It is usually set between 0.1 and 1.0. In this embodiment, it is set to 0.4, which can effectively balance the impact of current fluctuations on angle adjustment, ensure that the connector can still work normally when the current changes, and ensure the stability of signal transmission.

[0127] The preset third magnetic flux coefficient is a weight factor for adjusting the preset angle, which represents the effect of magnetic flux changes on the adjustment angle. It depends on the degree of influence of magnetic flux changes on the test signal quality and connector performance. It is usually set between 0.1 and 1.0. In this embodiment, it is set to 0.6 to ensure that when the magnetic flux changes, the system can flexibly adjust the angle, thereby improving the accuracy of signal transmission.

[0128] In the adjustment module, the third calculation unit performs comprehensive calculation according to the third adjustment mode, the real-time height difference, the real-time current, the real-time magnetic flux, and a series of preset standard parameters (such as preset standard magnetic flux, preset standard current, preset standard height, preset third height coefficient, preset third current coefficient, and preset third magnetic flux coefficient) to obtain the third adjustment angle. Subsequently, the third adjustment unit adjusts the preset angle according to the calculation result to form the final adjustment angle, thereby ensuring the adaptability and stable performance of the connector under complex conditions.

[0129] By introducing the calculation of the third adjustment angle, the module can achieve more refined angle adjustment, optimize the connection between the probe and the test equipment, improve the stability and reliability of signal transmission, and calculate the third adjustment angle by weighted summation, so that the influence of each parameter is reasonably balanced.

[0130] Specifically, the correction module includes:

[0131] A fluctuation calculation unit, used to calculate the standard deviation of the quantity of the adjustment angle to form a quantity fluctuation value;

[0132] A correction unit is connected to the fluctuation calculation unit and is used to correct the preset angle according to the quantity fluctuation value, the preset standard quantity fluctuation value and the preset correction coefficient when the quantity fluctuation value is greater than the preset standard quantity fluctuation value.

[0133] The preset correction coefficient refers to a specific coefficient used to adjust the preset angle in the correction module, which is usually set according to system performance, working environment and actual application requirements. It is usually set between 0.1 and 0.5 to ensure the sensitivity and stability of the angle adjustment. In this embodiment, it is set to 0.3, aiming to ensure the adjustment accuracy while avoiding the instability caused by too frequent adjustments, balancing the response speed and stability of the system and improving the overall work efficiency.

[0134] The standard deviation of the preset angle adjustment times is calculated by the fluctuation calculation unit to form a quantity fluctuation value. Subsequently, the correction unit determines whether an angle correction is required based on the comparison result between the quantity fluctuation value and the preset standard quantity fluctuation value. If the quantity fluctuation value exceeds the preset standard, the correction unit will use the preset correction coefficient to adjust the preset angle accordingly, thereby ensuring that the system maintains a stable and accurate angle setting during multiple adjustments.

[0135] By real-time monitoring and correction of fluctuations in the number of angle adjustments, angle deviations caused by frequent adjustments are avoided, thereby ensuring the accuracy of the probe connector during the test process.

[0136] Specifically, the determination module further includes:

[0137] An alarm unit is used to determine the abnormality type as a connection abnormality according to the comparison result that the consistency is less than or equal to the preset standard consistency, and to issue an alarm to check the connection point.

[0138] When the consistency is less than or equal to the preset standard consistency, it means that there is a significant difference in the current or magnetic flux between the input port and the output port. This difference may indicate a problem with the connection point, such as poor contact, loose connection or failure, which affects the accuracy and reliability of the test results.

[0139] By setting up an alarm unit, the reliability and safety of the system can be significantly improved. Issuing an alarm to check the connection point can promptly remind operators to conduct inspections and maintenance, ensure the normal operation of the system, and avoid misjudgment or equipment damage due to poor connection.
