Detailed Description
The present embodiments are only illustrative and not restrictive, and those skilled in the art can make modifications to the embodiments without inventive contribution as required after reading the present specification, but the technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to fig. 1 to 4 of the embodiments of the present application as long as they are protected by patent laws within the scope of the claims of the present application to make the objects, technical solutions and advantages of the embodiments of the present application clearer, and it is obvious that the described embodiments are a part of the embodiments of the present application, but not all of the embodiments.
The embodiment of the application provides a pressure control method, which can be applied to a pressure test system, wherein an execution main body can be an intelligent terminal and is realized by the assistance of a controlled solenoid valve system and a pressure reading instrument. As shown in fig. 1. The pressure testing system comprises an intelligent terminal, the intelligent terminal is in signal connection with both the controlled solenoid valve system and the pressure reading instrument, and the intelligent terminal can also acquire parameter information manually input. Specifically, when the controlled solenoid valve system works, mechanical pressure is generated and applied to a product to be tested through control over the solenoid valve, the pressure reading instrument can monitor air pressure existing in the controlled solenoid valve system, mechanical pressure borne by the product to be tested can also be monitored, the monitored data are returned to the intelligent terminal, and after the intelligent terminal receives the pressure data, the controlled solenoid valve system can be controlled according to the received pressure data.
The process flow shown in fig. 2 will be described in detail below with reference to the specific embodiments, and the contents may be as follows:
Wherein, the pressure test process at least comprises the test pressure set in a gradient manner.
In implementation, different semiconductor products have different requirements on performance due to different application environments, so that when a pressure test is performed and before pressure control is performed, the intelligent terminal first needs a pressure test flow to be executed by a current product to be tested. The pressure test flow here should include a plurality of test pressure values set during the pressure test, the test pressure should be set according to a certain pressure gradient, from low to high, and the difference between the test pressures of adjacent steps is the pressure difference.
In a specific embodiment, the pressure testing process is different for different semiconductor products, and accordingly, step 201 may be followed by the following steps: acquiring product information of the product to be detected, wherein the product information at least comprises a product size and a product model; and constructing a mapping relation between the product information and the pressure test process, and storing the mapping relation to a preset pressure test process library.
In implementation, after the pressure test system receives a batch of products to be tested, product information of the products to be tested can be entered into the intelligent terminal, the product information is used for identifying information such as the model and the size of the products, the product information can be entered by an engineer or identified by the pressure test system, for example, product codes and the like are identified by an image identification technology. After the intelligent terminal acquires the product information, the pressure test flow to be executed on the product to be tested can be acquired, and then the current product to be tested and the pressure test flow can be associated to construct the mapping relation between the product to be tested and the pressure test flow. Specifically, in the mapping relationship between the product to be tested and the pressure testing process, the product to be tested should not be limited to the current batch of products, but should be summarized as product information such as product size and product model, so as to form the association between the product information and the pressure testing process. In practical application, even the same model of product may be suitable for different quality standards, and the same pressure test process may also be suitable for testing various models of products, so the mapping relationship between the product information and the pressure test process should be many-to-many. After the mapping relation between the product information and the pressure test process is obtained, the mapping relation can be stored in a preset pressure test process library.
Therefore, the intelligent terminal can establish a mapping relation between the product and the pressure test process, is beneficial to quickly acquiring the pressure test process related to the product, replaces manual input, and is beneficial to improving the efficiency of the pressure test of the product.
In a specific embodiment, after the mapping relationship between the product information and the pressure testing process is established, the following processing may be further included: before product testing, first product information of the product to be tested is acquired; retrieving product information matched with the first product information in the pressure test process library; and if the product information matched with the first product information exists, directly calling a pressure test flow matched with the product information.
In implementation, the intelligent terminal can obtain first product information of a current product to be tested, search is carried out in the pressure test flow library based on the first product information, and if the mapping relation between the first product information and the pressure test flow can be searched, the stored pressure test flow can be directly called. In particular, when the above-mentioned product information simultaneously corresponds to a plurality of stress test procedures, an engineer is required to intervene to make the selection.
Therefore, the intelligent terminal can identify and retrieve the product information of the product, automatically match the corresponding pressure test flow, and is beneficial to replacing manual input or manual search by engineers, so that the test efficiency is improved.
In implementation, in order to perform the fuzzy operation, it is necessary to obtain a deviation value between adjacent parameters, in the pressure control described in this embodiment, the deviation value is a pressure difference between adjacent test pressures, and the intelligent terminal may make a difference between a current first test pressure and a next second test pressure, where an absolute value of the obtained difference is a pressure difference.
Therefore, the intelligent terminal can simultaneously obtain the current value and the deviation value, and calculation of the control parameters in subsequent fuzzy control is facilitated.
In a specific embodiment, each time the pressure difference needs to be detected, the calculation is performed, which results in low calculation efficiency, and accordingly, step 202 may further include the following steps: acquiring a pressure difference between the test pressures of adjacent steps based on the test pressures set by the gradient, wherein the pressure difference is acquired by making a difference between a post-jump test pressure and a pre-jump test pressure; the pressure differential is correlated with a preceding stage test pressure corresponding to the pressure differential.
In implementation, after the intelligent terminal acquires the pressure test flow, the pressure test flow can be analyzed to acquire different test pressures involved in the pressure test flow, on the basis, the pressure difference between the test pressures of adjacent steps can be acquired by making differences one by one, and in order to facilitate calculation of control parameters in fuzzy control, the pressure difference and the previous test pressure during making the differences can be associated and bound to form input parameters of current values and deviation values.
In application, the intelligent terminal only needs to acquire the current test pressure in the process of pressure test, and the pressure difference corresponding to the current test pressure can be directly acquired according to the binding relationship among the current test pressure, the pressure difference and the test pressure, so that the calculation steps are favorably reduced and avoided.
Like this, after intelligent terminal acquireed current test pressure, directly acquire the pressure differential according to test pressure, replaced all need just can obtain the pressure differential through calculating after detecting at every turn, help improving the efficiency of product pressure test work.
In implementation, after the intelligent terminal obtains a current value of the test pressure and a deviation value of the pressure difference, the test pressure and the pressure difference can be used as input parameters and input into the fuzzy controller, the fuzzy controller can call algorithm plug-in units in a Matlab library, a gravity center method fuzzy operation algorithm can be specifically selected, and control parameters are finally obtained through fuzzification, fuzzy rule inference and defuzzification processes. And finally, the control parameters output by the fuzzy controller are the pressure control flow and the control duration.
Thus, the fuzzy control parameters are used for replacing the operation of assembling and disassembling the electromagnetic valve, and the efficiency of pressure control in the pressure test is improved.
And step 204, controlling the controlled system to execute a pressure test based on the control parameters.
In implementation, in the control parameters acquired by the intelligent terminal, the pressure control flow rate can be realized by regulating and controlling the electromagnetic valves, the controlled electromagnetic valve system can comprise electromagnetic valves with different specifications, wherein the specifications of the electromagnetic valves should be based on the flow rate, and the electronic control switching operation can be realized among different electromagnetic valves through the switching valve. The control duration is the time that the pressure control flow at the current test pressure needs to last.
Therefore, the intelligent terminal can change the pressure value through the control parameter, obtain the required test pressure and contribute to improving the efficiency of the pressure test.
In a specific embodiment, the test environment is also provided with upper and lower limits of the ambient air pressure for safety, and accordingly, the pressure control method may further include the following steps: acquiring a tested third test pressure of the product to be tested; when the third test pressure is lower than a preset lower limit of the environmental pressure, increasing the pressure control flow; and when the third pressure measurement and test pressure is higher than the preset upper limit of the environmental pressure, reducing the pressure control flow.
Like this, intelligent terminal monitors test environment at the in-process of pressure test, and when pressure in the test environment exceeded the upper limit and the lower limit of safe operation, environmental pressure can be adjusted through the size of control pressure control flow, reaches the effect of guaranteeing test environment safety.
In a specific embodiment, if the test environment generates gas leakage, the test pressure may be out of order, and the test result may be inaccurate, and accordingly, the pressure control method may further include the following steps: acquiring test environment air pressure according to a preset detection period, and acquiring an environment air pressure mean value in each detection period; and if the error between the first ambient air pressure mean value in the current detection period and the second ambient air pressure mean value in the previous detection period is over the preset leakage threshold value, updating the control parameter.
In implementation, the preset detection period is used for detecting the environmental pressure, and may be set to 1 minute, 2 minutes, 5 minutes, and the like. After the intelligent terminal obtains the testing environment air pressure, the environment air pressure mean value can be calculated for the testing environment air pressure in a detection period, the environment air pressure mean values of the front period and the rear period are compared, the comparison result is compared with the leakage threshold value, and if the deviation between the front period and the rear period exceeds the leakage threshold value, the leakage fault can be judged to occur. On the basis, in order to maintain the test pressure on the product, the control parameters can be updated to meet the test pressure required by the pressure test process based on the test pressure currently suffered by the product to be tested.
Like this, intelligent terminal can monitor ambient pressure, and when ambient pressure took place obvious deviation, intelligent terminal can judge the gas leakage condition that probably exists in the test environment, and then updates control parameter, and new control parameter after the control parameter updates can keep the pressure that receives of product, helps guaranteeing the stability that the product tested in the test environment of difference.
