[0027] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0028] The command can be obtained by mechanical button triggering or virtual button triggering. In the mechanical button triggering method, the command can be automatically obtained after turning on the power by pressing the power button, or the current behavior information can be obtained by pressing the corresponding trigger button again after turning on the power. In the virtual button triggering method, the command can be obtained by pressing the relevant virtual trigger button in the interface of the corresponding software.

[0029] The present application embodiment discloses a high temperature reverse bias aging test method. Figure 1 , a high temperature reverse bias aging test method includes: Step S100: Get a test instruction.

[0030] Specifically, the host computer receives instructions from the tester by connecting to the test equipment. The tester can trigger the test instructions by triggering the human-computer interaction interface of the host computer. The host computer can use the eBOX560-522-FL model industrial computer, which supports high-speed data acquisition and real-time monitoring, provides powerful data recording and report generation functions, and supports interface docking with a variety of sensors and test equipment; the test equipment can use the T / 60 / V2 model high-temperature test box and the aging board placed in the high-temperature test box. The aging board is provided with multiple contact points or slots for connecting the items under test of different packaging types. These contact points usually include pads, pins, terminal blocks or quick connectors to establish electrical connections with the items under test.

[0031] Step S200: Obtain product information of the device to be tested according to the test instruction.

[0032] Specifically, according to the obtained test instructions, the host computer reads the product information stored in the database, including: product model, product material, rated withstand voltage, operating environment (such as temperature, humidity), and usage specifications (such as power and size). The data in the database can be obtained through the Internet or uploaded by the tester. The engineer enters the basic information of the device to be tested, such as product model, product material, rated withstand voltage, operating environment (such as temperature, humidity), and usage specifications (such as power and size) through the operation interface.

[0033] Step S300: Acquire test duration, test environment, and corresponding test voltage based on product information of the device to be tested.

[0034] Specifically, the test standards are defined for each product, including: test duration (e.g., several hours to several days), test environment (e.g., high temperature, humidity control), and test voltage (voltage set according to the rated withstand voltage).

[0035] Step S400: Starting testing of the device to be tested based on the test time, test environment and corresponding test voltage and obtaining test results.

[0036] Reference Figure 2 The specific steps of the test include: Step S410: adjusting the ambient temperature and ambient humidity based on the test environment and obtaining real-time environmental information; Step S420: If the real-time environment information is not synchronized with the set environment information within the set time, output a fault message and stop the test; Step S430: If the real-time environment information is synchronized with the set environment information within the set time, the test duration is set based on the test time and the input reverse voltage is set based on the test voltage; Step S440: starting to test the device to be tested under a set environment based on the set test duration and reverse voltage and obtaining real-time current information and real-time resistance information of the device to be tested; Step S450: Generate test results based on real-time current information and real-time resistance information. Specifically, the host computer automatically matches and obtains the above test standards based on the product information, automatically inputs the target environmental temperature and humidity values, and gradually adjusts the test environment by controlling the test equipment to ensure that the host computer can monitor the real-time temperature and humidity information. During this period, temperature and humidity sensors can be installed in the test environment to collect data in real time. The sensor data is regularly read through the data acquisition module (such as Arduino, Raspberry Pi, etc.) and sent to the main control system. The designer sets a time window according to the specifications of the environmental test chamber, and continuously compares the real-time temperature and humidity information with the target value within the set time. If the target value is not reached within the set time, a fault message is output and an instruction to stop the test is triggered. If the real-time environmental information meets the requirements, the system sets the test parameters according to the preset test time and voltage value, and uses the control interface of the test equipment to set the input reverse voltage to start the test. The equipment applies the reverse voltage within the set test duration. During the test, the current and resistance data are collected in real time. You can use a data acquisition card or test instrument to read real-time data, store the collected real-time current and resistance information in a database or file, analyze the current and resistance changes according to the preset calculation formula (such as Ohm's law), and finally generate a test report, including: test time, test environment information (temperature, humidity), test voltage, real-time current and resistance information, and the result compared with the standard (qualified / unqualified). The current can record the real-time current and maximum current, and the resistance can record the real-time resistance and maximum resistance.

[0037] Step S500: If the test result does not meet the high temperature aging standard conditions, a warning message is output.

[0038] Specifically, the test results are compared with the predefined high temperature aging standards, and thresholds (such as maximum allowable current, temperature, etc.) are set. If the test results do not meet the standards, a warning message is automatically generated and notified to the operator. This can be prompted through the interface, that is, a warning character with a red border is displayed on the human-computer interaction page.

[0039] For example, during the test, the item to be tested is a semiconductor diode. The tester enters the model of the product and the test command. The industrial computer automatically retrieves the product information of the device to be tested according to the input command, and determines the test duration, test environment and corresponding test voltage according to the product information (diode SF58G: test duration: 1 hour, test environment: ambient temperature: 150°C, ambient humidity: 50%, reverse voltage: 420V). By controlling the temperature in the high temperature box, the device to be tested is gradually heated to 150°C and the humidity is adjusted to 50%. During this period, the system continuously monitors the real-time environmental information. Assuming that the ambient temperature and humidity sensors deviate, within the set time range (for example, within 3 minutes), if the system fails to successfully adjust to the set environment, the system will output fault information and stop the test. The fault information may include: fault type: the environment does not meet the standard or the environment is unstable; fault time: the specific time when the fault occurs; fault description: the ambient temperature and humidity do not meet the set conditions. After ensuring that the temperature and humidity are stable, the test system begins to apply a reverse voltage of 420 to the device to be tested to simulate the electrical load under long-term high temperature. During the test, the system monitors the key parameters of the device in real time, such as the reverse current, the forward resistance and reverse resistance of the diode, temperature changes, and performance changes, collects and records these data, and the system determines these data. For example, under normal working conditions, the reverse current should be kept within a certain range (for example, less than 1μA); the resistance should remain stable without obvious drift. During the test, the system detects that the reverse current exceeds the set safety range at a certain point in time, or the resistance changes abnormally. At this time, the system will output a warning message, including: Warning type: high temperature aging test results are unqualified; Abnormal description: Out of current range / resistance drift is too large; Recommended operation: Stop the test and check the device. If it meets the high temperature aging standard conditions, it can also be tested multiple times to avoid errors.

[0040] Reference Figure 3 If the test results do not meet the high temperature aging standard conditions, retesting is required. The specific steps include: Step S510: obtaining a retest instruction; Step S520: Checking the device status based on the retest instruction and generating retest product information; Step S530: If the device status meets the retest standard, retest parameters are set based on the retest product information, and the retest parameters include test duration, test environment and test voltage; Step S540: retesting the device based on the retest parameters and outputting the retest results; Step S550: If the retest result does not meet the retest conditions, output unqualified information. Specifically, the operator inputs the retest instruction through a button or command. After receiving the retest instruction, the system queries the status of the device to be retested according to the previous test records, including: test results (qualified / unqualified), environmental conditions (temperature, humidity, etc.), and voltage information. The relevant status information is integrated into the retest product information, including the following: product ID, last test result, current environmental information, parameters required for retest, etc. The retest standard is defined according to the product standard, such as: current, voltage range; environmental condition restrictions, and the standard can be obtained from multiple experiments. The current device status is compared with the retest standard to confirm whether it meets the standard. If the device status meets the retest standard, the retest parameters are extracted and set from the retest product information, including: Test duration: set according to previous test experience or product specifications. Test environment: readjust or keep consistent as needed, which may include temperature and humidity settings (the standard can be lowered when the product ages to a certain extent). Test voltage: set the reverse voltage according to previous tests or product specifications. Connect the device to be retested to the test equipment and start the retest procedure. Apply retest voltage within the set test duration, monitor current and resistance in real time, and record real-time current and resistance information in the database. Analyze the collected data and generate retest results, including: retest current and resistance information; pass / fail judgment basis. Display the retest results through the user interface, including: retest current and resistance value, judgment result (pass / fail). If the retest results do not meet the retest conditions, the system will automatically output unqualified information, which can be notified to the operator through pop-up windows on the interface, email notifications, etc., and mark the device with the ID as unqualified in the database for subsequent distinction.

[0041] In addition, if the real-time environment information is not synchronized with the set environment information within the set time, a fault analysis is required. The specific steps include: Step SA1: If the real-time environmental information is not synchronized with the set environmental information within the set time, the temperature change curve and the humidity change curve are obtained; Step SA2: Analyze curve characteristics according to the temperature change curve and the humidity change curve; Step SA3: Determine fault information based on curve characteristics.

[0042] Specifically, monitor environmental data within a set time. If the temperature or humidity does not reach the set value, the fault handling process is triggered. When the environmental conditions do not meet the standards, the temperature and humidity data within the time window are collected. These data are organized into time series to draw curves. Use data visualization tools (such as Matplotlib or Excel) to draw the collected temperature and humidity data into a curve graph, and analyze the curve characteristics, including: peak and valley values ​​(maximum and minimum values), rising and falling trends, and time periods that continue to deviate from the set values ​​to determine whether there are abnormal conditions, such as: temperature or humidity continues to be higher or lower than the set range; sudden fluctuations or sharp changes. Machine learning algorithms (such as classification algorithms) can also be used to help determine the cause of the fault. Based on the extracted features, fault information is generated. The fault information includes the location of the damaged temperature adjustment device and humidity adjustment device and repair suggestions.

[0043] It is also possible to establish a historical database to calculate the product qualification rate. The specific steps include: Step SB1: Establish a historical database based on product information and test results; Step SB2: Calculate the qualified rate of the current device to be tested based on the historical database; Step SB3: comparing the pass rate with the set standard; Step SB4: If the pass rate does not meet the set standard, the test device is determined to be unqualified and output a quality report. Specifically, the device to be tested is tested using the corresponding test voltage at the set test time and environment. The test results of each device are collected, including the qualified or unqualified status, and a historical database is designed, which contains the following fields: product information (such as model, version, etc.), test results (qualified / unqualified), test time, test environment (such as temperature, humidity, etc.), and test voltage. The results and related information of each test are recorded in the database. A relational database (such as MySQL, PostgreSQL) or a non-relational database (such as MongoDB) can be used. A query script is written to extract all test records of the current device to be tested from the historical database, and the number of qualified and unqualified data is counted according to the extracted data. A qualified rate standard is set, which is entered in advance by the designer. Exceeding this qualified rate affects the product yield, and the calculated qualified rate is compared with the set standard. If the qualified rate is lower than the set standard, the test device is judged to be unqualified. If the qualified rate meets or exceeds the standard, it is judged to be qualified. If it is judged to be unqualified, a quality report is generated, and the content should include: product information, test results, qualified rate, comparison standard, and judgment result (qualified / unqualified). Finally, the quality report of each test is archived for subsequent query and analysis.

[0044] It also includes steps for real-time feedback, including: Step SC1: acquiring historical test data of the same product based on the product information of the device to be tested; Step SC2: Compare and analyze the historical test data and the real-time test results, and generate a comparison result; Step SC3: Based on the comparison results, dynamically generate feedback information and display the feedback information on the human-computer interaction interface. Specifically, when testing a batch of products again, query the test records of the same product in the historical database through the product information of the device to be tested (such as model, version, etc.). You can use SQL query or similar database access tools to extract relevant historical test data. Get real-time test results and format them into the same structure as historical data for easy comparison. Select appropriate comparison indicators, such as: pass rate, test result distribution (pass / fail number), performance indicators (such as voltage, power consumption, etc.). Based on the results of the comparative analysis, generate a detailed comparison report, including: real-time test results of the device to be tested, historical test results of the same product, difference analysis (such as pass rate changes, performance fluctuations, etc.), and generate feedback information based on the comparison results. The content may include: whether the performance of the test device is in line with historical trends, recommended areas for improvement (such as adjusting test parameters), and expectations for future tests (such as estimated pass rate), and display them on the human-computer interaction page in the form of tables and charts.
