[0043] The present embodiment discloses a reliability calculation method, as shown in the following steps: Figure 1

[0044] Obtain the component basic information table and the reliability input table, the component basic information table includes multiple component basic information, and the reliability input table includes multiple task profiles of each component;

[0045] Select a component to be calculated based on the component basic information table;

[0046] Determine the target task profile of the component to be calculated based on the reliability input table;

[0047] Calculate the reliability data of each target task profile of each component to be calculated based on the component to be calculated and the target task profile; ​

[0048] allocating the reliability data of each target mission profile of each component to be calculated to a calculation result table;

[0049] obtaining the reliability of each component based on the calculation result table and a preset reliability allocation report.

[0050] In the embodiment, a reliability calculation method is provided. First, a component basic information table and a reliability input table are obtained. Then, a component to be calculated is selected based on the component basic information table, and a target mission profile is selected based on the component to be calculated and the reliability input table. The reliability data of each mission profile is obtained by using a reliability standard calculation formula based on the selected component to be calculated and the target mission profile. Finally, the reliability data of each mission profile is allocated to the corresponding calculation result table, and the reliability of the component is obtained based on the comparison between the calculation result table and a preset reliability allocation report.

[0051] Specifically, the component basic information table is an Excel table containing information of multiple components whose reliability needs to be calculated. Different workbooks contain information of different components, including the name or code of the component and some parameters required for reliability analysis. The types of parameters vary according to different components. For example, Table 1 shows a component basic information table of a certain component, which mainly includes parameters such as module, model, single set quantity, packaging type, pin number, gate number, maturity stage, cycle rate, quality level, and domestic and foreign environment.

[0052] Table 1 Component basic information table

[0053]

[0054]

[0055] Specifically, the reliability input table contains multiple mission profiles of each component. Mission profile refers to the working state of the component and its corresponding life process, different environmental coefficients and temperature coefficients, and even some special requirements, such as different environmental coefficients required for domestic and foreign components. Different workbooks in the same table record different working states of the same component, as well as the corresponding mission profile of the working state and the influencing factors of the mission state for other reliability analysis. As shown in Table 2, it is a mission profile of a certain component under a certain working state, which records its mission profile and the corresponding influencing factors of other reliability analysis, such as in the mission profile delivery road transportation, the corresponding influencing factors of reliability analysis include: ground environment domestic, ground environment foreign, environmental temperature, working state, time, environmental domestic calculation value, environmental foreign calculation value, etc.

[0056] Table 2 Reliability input table

[0057]

[0058] Specifically, in the calculation, the standard calculation formula is used to calculate each task profile of each component, and the reliability data of all task profiles is obtained, and then the reliability data is distributed to the calculation result table according to the name. The calculation result table records the reliability data of each task profile of each component, and the calculation result table is shown in Table 3.

[0059] Table 3 Calculation result table

[0060]

[0061]

[0062] Specifically, the reliability of the component to be calculated is obtained based on the weighted sum of the reliability data of all target task profiles of the component to be calculated. The reliability of the component is not simply the superposition of the reliability data of each task profile of the component, and the participation of each task profile in the component needs to be considered. Therefore, a weight is added to the reliability data of each task profile, and then the reliability data of each task profile after weighting is added to obtain the reliability of the component.

[0063] Specifically, the reliability of the component is distributed to the calculation report example table in order to facilitate comparison with the reliability distribution report to obtain the reliability condition of the component. The calculation report example table contains the overall reliability of the component, as shown in Table 4.

[0064] Table 4 Calculation report example table

[0065] Status ZT02 Requirement 0.9874 Forecast 0.9912 Determination Qualified Life process Section 1 Section 2 Section 3 Section 4 Section 5 Section 6 Section 7 Section 8 Time 40 8760 20 4380 60 0.0013 0.5 0.0333 Reliability Total DZ_PS (chip resistor) DR_1L (class 1 capacitor) DR_2L (class 2 capacitor) YZHD (printed board solder joint) JZ (crystal) LB_DZ (filter) DG_PS (inductor class) LJQ (connector) EJ_TZ (discrete device) XP_GN (domestic chip) XP_GW (foreign chip)

[0066] Specifically, the reliability condition of the component is obtained by comparing the calculation result table with the preset reliability distribution report. The reliability distribution report contains the reliability distribution result of the component based on the national standard or industry standard, and is used to compare the calculated result to determine whether the component meets the use requirement in the task profile. The reliability distribution report is shown in Table 5.

[0067] Table 5 Reliability distribution report

[0068]

[0069]

[0070] Specifically, the reliability condition refers to whether the calculated reliability meets the use requirement.

[0071] Specifically, by the reliability calculation method, the components to be calculated can be flexibly selected, and the target task profiles of the components to be calculated can also be flexibly selected. In addition, by comparing the reliability of each task profile with the result in the reliability allocation report, it can be known whether a certain component of the component meets the use requirement, and targeted improvement can be made.

[0072] In some embodiments, the target task profile of the component to be calculated is determined based on the reliability input table, including:

[0073] In the case of selecting a task profile from the reliability input table, the selected task profile to be calculated from the reliability input table is taken as the target task profile.

[0074] If the task profile is not selected from the reliability input table, all task profiles of the component to be calculated are taken as the target task profile.

[0075] In the embodiment, the reliability input table contains multiple target task profiles. In actual application scenarios, each component corresponds to multiple working states, and the task profiles corresponding to each working state are different. Therefore, multiple task profiles of the component are recorded in the reliability input table. When the reliability of a certain working state is calculated, the corresponding task profile may be several, and therefore needs to be selected. If the task profile is not selected, all task profiles of the component corresponding to the reliability input table are calculated, which may cause waste of computing resources to some extent.

[0076] In some embodiments, the reliability data of each target task profile of each component to be calculated is calculated based on the component to be calculated and the target task profile, including:

[0077] Based on the basic information table of the component to be calculated and the preset component reliability coefficient table, a component information feedback table is obtained, wherein the reliability coefficient table includes basic information of all components and corresponding standard reliability coefficients, and the component information feedback table contains basic information of the component to be calculated and reliability coefficients obtained from the reliability coefficient table.

[0078] Based on the component information feedback table and the reliability input table, the reliability data of each target task profile of each component to be calculated is calculated.

[0079] In the embodiment, when calculating the reliability data, the component basic information table is converted into the component information feedback table through the preset reliability coefficient table, and then the component information feedback table and the reliability input table are called to calculate the reliability data of each target task profile.

[0080] Specifically, the reliability coefficient table is a standard table based on national standards or industry standards, which contains all components and their corresponding reliability coefficients. Through the reliability coefficient table, the reliability coefficient of the component to be calculated can be obtained, and then the component information feedback table containing the basic information of the component and its corresponding reliability coefficient is used to participate in the calculation of reliability. The calculation process is to import the relevant parameters into the standard calculation formula for calculation to obtain the reliability data. The reliability coefficient table is shown in Table 6, and the component information feedback table is shown in Table 7.

[0087] The reliability data of the one component includes reliability data of all target mission profiles of the component.

[0088] In this embodiment, the calculation result table contains reliability data of a plurality of mission profiles of a plurality of components, which need to be distinguished.

[0089] Specifically, each workbook contains reliability data of one component.

[0090] Specifically, each workbook contains reliability data of all target mission profiles.

[0091] In some embodiments, the reliability condition includes:

[0092] If the reliability data of a certain mission profile in the calculation report example table is greater than or equal to the corresponding reliability allocation result in the reliability allocation table, the reliability of the mission profile meets the use requirement.

[0093] If the reliability data of a certain mission profile in the calculation report example table is less than the corresponding reliability allocation result in the reliability allocation table, the reliability of the mission profile does not meet the use requirement.

[0094] In the embodiment, if the reliability data of a task profile in the report example table is greater than or equal to the corresponding reliability allocation result in the reliability allocation table, the reliability of the task profile meets the use requirement; if the reliability data of a task profile in the report example table is less than the corresponding reliability allocation result in the reliability allocation table, the reliability of the task profile cannot meet the use requirement, and the properties of the components corresponding to the task profile need to be optimized.

[0095] In some embodiments, in response to the reliability of a task profile in the report example table not meeting the use requirement, the corresponding properties of the components corresponding to the task profile are optimized.

[0096] In the embodiment, in response to the reliability of a task profile in the report example table not meeting the use requirement, that is, the task profile is smaller than the corresponding reliability allocation result in the reliability allocation table, the properties of the components corresponding to the task profile are optimized.

[0097] Specifically, for example, if it is found that the reliability of the service life of a circuit board under high temperature of 80-100 ℃ cannot meet the use requirement during reliability calculation, the factors affecting the service life of the circuit board under high temperature of 80-100 ℃ corresponding to the task profile are improved, for example, the heat dissipation system is improved, the material quality is improved, the welding process is improved, and the like.

[0098] In some embodiments, after the corresponding properties of the components corresponding to the task profile are optimized, the reliability of the components is calculated again.

[0099] The regression calculation includes: recalculating the reliability of the components and the reliability data of the corresponding task profile, if the use requirement is still not met, the optimization is continued, the calculation is performed again, and the process is repeated until the reliability of the components meets the use requirement.

[0100] In the embodiment, the reliability of the optimized components is recalculated, if the reliability of the components meets the use requirement, the optimization is stopped; if the use requirement is still not met, the optimization is continued, and the regression calculation is performed again until the reliability of the components meets the use requirement.
