[0061] The working principle of a one-stop insertion loss strip optimization design method provided by the present invention is as follows:

[0062] During operation, first select the production of the insertion loss strip: In the operation interface of the PCB design software, find the dedicated "Coupon strip production" function module or menu option. Under this module, accurately locate and select the specific function of "insertion loss strip production" from the provided multiple types of test strip options. This step is the starting point of the entire process, clarifying that the subsequent operation goal is to create design elements and data preparation related to the insertion loss strip.

[0063] Click the (Get MI information button) to obtain the insertion loss information in the MI software: When the production of the insertion loss strip is selected, an operation button named "Get MI information button" will be displayed on the interface, usually located in the operation area related to the production of the insertion loss strip for the convenience of users to quickly find and click.

[0064] After clicking this button, the system will automatically initiate a communication connection with the MI (Manufacturing Instructions) software. Through a pre-set interface protocol, it sends a data request instruction to the MI software to obtain detailed information closely related to the production of the insertion loss strip. This information includes but is not limited to data on the physical parameters, electrical characteristics, and layer stack structure of the circuit. These data are the key basis for the subsequent design and production of the insertion loss strip.

[0065] Check against the actual data (to prevent misoperation by MI production personnel) and check the information such as the layer where the insertion loss impedance line is located, the reference layer, the line width and line pitch shown in the above figure (to prevent misoperation by MI engineers):

[0066] The system displays the insertion loss bar information obtained from the MI software in the form of intuitive charts or data lists on the operation interface, facilitating users to view and check.

[0067] For the layer where the insertion loss impedance line is located, carefully compare the layer identifier in the MI information (such as L3 in the example indicating the third layer) with the layer where this impedance line should be located as planned in the actual PCB design data to ensure they are exactly the same. This step is crucial because if there is an error in the layer where the impedance line is located, it will directly affect the electrical performance and signal transmission characteristics of the PCB.

[0068] Similarly, check the reference layer information. Reference layer 1 and reference layer 2 serve as the shielding layers of the impedance line, and their correct settings play a key role in ensuring signal integrity and reducing interference. Check whether the material, position of the reference layer, and the relative relationship with the impedance line match the actual design data to avoid signal leakage or interference problems caused by incorrect reference layer settings.

[0069] Regarding the line width and line spacing information, compare the impedance line width and line spacing values provided in the MI with the company's established process capability standards. The company's process capability standards are determined based on long-term production experience and process technology levels to ensure that the line width and line spacing are within a reasonable range for production, which can not only meet the electrical performance requirements but also ensure manufacturability during actual production. At the same time, also check whether these values match the specific requirements of the customer to prevent impedance deviation and signal transmission problems caused by inaccurate line width and line spacing.

[0070] After verification, click the (Execute Button) in the above figure to execute the data: After carefully checking the key information such as the layer where the insertion loss impedance line is located, the reference layer, and the line width and line spacing, and confirming that all information is accurate, find the "Execute Button" on the operation interface. This button is usually designed in a prominent style to highlight its importance and the irreversibility of the operation. Before clicking the execute button, the user should confirm all the verified information again to ensure there are no omissions or errors. Once the execute button is clicked, the system will start a series of automated operations based on the obtained and verified MI information, including but not limited to creating or updating relevant design elements of the insertion loss bar in the PCB design file, such as drawing accurate impedance line graphics, setting correct layer attributes and electrical parameters, etc., to convert the design intent into actual producible PCB design data.

[0071] View the final result: After the execute button is clicked, the system will enter the data execution and processing stage. This process may take a certain amount of time, and the specific duration depends on the complexity of the PCB design and the performance of the computer system.

[0072] After the system completes all operations, it will automatically switch to the result display interface, or display the final result in a specific area of the original operation interface. Users can view the detailed results of the insertion loss bar production here, including but not limited to the actual presentation effect of the insertion loss bar in the PCB design, the calculation results and display of various electrical parameters (such as ohmic values, etc.), and other auxiliary information related to the insertion loss bar (such as back drill information, hole diameter information, etc.). Users need to carefully check these results to ensure that the design of the insertion loss bar fully meets the expected requirements and standards. If any abnormalities or non-compliant points are found, they should trace back to the previous steps for investigation and correction, and if necessary, re-obtain the MI information and repeat the entire production process.

[0073] Compared with the related technologies, a one-stop insertion loss bar optimization design method provided by the present invention has the following beneficial effects:

[0074] The present invention provides a one-stop insertion loss bar optimization design method. By optimizing the production of the existing impedance bar, the process of the CAM engineer selecting the insertion loss impedance information to be produced is changed to automatically obtaining the parameters provided in the software, checking the back drill surface order, size, back drill stub depth, impedance line width and line spacing, compensation value, etc. Through automated acquisition and comparison for production, the consistency between the insertion loss bar with or without the back drill process and the indication can be improved, reducing production abnormalities caused by errors in the back drill surface order, size, and stub depth in the department, and having the advantages of improving the quality and efficiency of the department. It solves the abnormal points brought by the CAM engineer manually adding the back drill process in the insertion loss bar, and at the same time reduces manual operations. Instead of manually adding the back drill before, by one-stop grabbing the existing data in the MI software and running the production of the insertion loss bar, the mistakes of manual operations are reduced, and the quality and efficiency of the department are improved.

[0082] A12: Use data verification algorithms to perform real-time verification on the extracted information, automatically check the reasonable range of line width and line spacing and the tolerance range of the ohm value, and immediately issue an alarm if abnormal data is found, and prompt possible causes of errors and correction suggestions.

[0084] A22: The simulation software calculates the signal transmission performance indicators of the insertion loss strip under different parameter combinations, including insertion loss value, return loss and crosstalk. By analyzing and comparing the indicators, the parameter combination with the best performance is screened out and used as the recommended optimization solution.

[0085] A3 includes the following steps: A31: After determining the optimization plan, the system automatically generates an execution script to update the optimized parameters into the PCB design file. The execution script uses automated process control technology to ensure the accuracy and consistency of data updates and avoid errors that may be introduced by manual operations.

[0086] A32: During the execution process, the system monitors the execution status of each step in real time and feeds back the execution results to the user. The user can view the design modification status, execution progress and final optimization results of the insertion loss strip through the visual interface. If an error occurs during the execution process, the system will automatically roll back to the last stable state and record the error information in detail to facilitate the user to troubleshoot and solve the problem.

[0087] In another optional manner of the present embodiment, the one-stop insertion loss strip optimization design method may also not include the steps of S1: selecting insertion loss strip production; S2: clicking the Get MI Information button to obtain the insertion loss information required to be produced in the MI software; S3: verifying the layer where the insertion loss impedance line is located, the reference layer and the line width and line spacing information with the actual data; S4: clicking the Execute button to execute the data after verification; S5: checking the final result; it only needs to be satisfied and does not hinder the one-stop insertion loss strip optimization design method from running the insertion loss strip production by one-stop grabbing of the existing data in the MI software, reducing human operation errors, and improving the departmental quality effect.

[0088] In another alternative manner of this embodiment, the one-stop insertion loss bar optimization design method may also include functional modules in the prior art to replace the following steps: S1: Select the production of the insertion loss bar; S2: Click the button to obtain MI information to obtain the insertion loss information required in the MI software; S3: Check the layer where the insertion loss impedance line is located, the reference layer, and the line width and line spacing information with the actual data; S4: After verification, click the execution button to execute the data; S5: View the final result and implement the same functions of the above modules. It only needs to meet the functional modules in the prior art, and it does not prevent the one-stop insertion loss bar optimization design method from running the production of the insertion loss bar by grabbing the existing data in the MI software in one stop, reducing human operation errors and improving the quality effect of the department.

[0089] The working principle of the one-stop insertion loss bar optimization design method provided by the present invention is as follows:

The automated data acquisition and integration process greatly shortens the time to obtain the design information of the insertion loss bar. The parameter optimization and simulation analysis process can quickly screen out the optimal solution, reducing the time of manual repeated attempts and adjustments. Due to the improvement of design efficiency, the input of labor cost and time cost is reduced. At the same time, the optimized design reduces the PCB scrap rate caused by poor performance of the insertion loss bar, reducing production costs. In addition, by avoiding potential design errors and rework, the material cost and energy consumption in the production process are also saved. The software architecture design of this solution has good flexibility and scalability, and can easily integrate new design tools and technologies.
