[0023] See also Figure 1 , is a schematic flow chart of an insertion loss evaluation method provided by an embodiment of the present invention. The insertion loss evaluation method is applied in a terminal. The professional terms in this embodiment are explained below.

[0024] Insertion loss (IL): The loss of energy or gain when certain devices or branch circuits (filters, impedance matchers, etc.) are added to a circuit. Insertion loss refers to the signal loss caused by inserting cables or components between the transmitter and the receiver, usually referred to as attenuation. Insertion loss is expressed in decibels (dB) corresponding to the received signal level.

[0025] Figure 1 1 is a flow chart of an insertion loss evaluation method provided by an embodiment of the present invention. As shown in the figure, the method includes the following steps S110-S150.

[0026] S110 , receiving design parameters of a PCB to be manufactured input by a user, wherein the design parameters include an insertion loss value, wherein the design parameters include an insertion loss value.

[0027] In one embodiment, the PCB to be manufactured is a PCB newly designed by the customer, which is different from the previous PCB and has different insertion loss requirements. A software tool is pre-installed in the terminal, and the software tool displays a user input interface for the user to enter design parameters in the interface. The terminal can be a desktop computer, a laptop computer or an industrial computer. Among them, the design parameters refer to the relevant structure or model parameters of the PCB design, such as PCB material, copper foil type, copper foil thickness, semi-cured sheet model, semi-cured sheet thickness, core board model, core board thickness, line width and line width spacing, etc. Among them, the design parameters also include insertion loss values, and the insertion loss values ​​represent the customer's requirements for the PCB insertion loss capability. When it is sent to the PCB manufacturing factory based on the customer design and insertion loss requirements, the PCB manufacturing factory can input the design parameters of the corresponding design according to the design of the PCB, and use the design parameters to evaluate the insertion loss capability of the newly designed PCB.

[0028] S120: Acquire, according to the design parameters, an identical design matching the design parameters from a preset database.

[0029] In one embodiment, the preset database refers to a database pre-stored with parameters related to past PCBs, wherein the parameters related to past PCBs may be manufacturing parameters of manufactured PCBs, design parameters of PCBs obtained by simulation design, or design parameters determined based on manufacturing experience, etc. After obtaining the design parameters, the design parameters are matched one by one with all relevant parameters in the preset database. Specifically, for example, if there are two PCBs with design numbers S001 and S002 in the preset database, then the design parameters are matched with the parameters corresponding to S001, and matched with the parameters corresponding to S002. The matching process is that the parameters such as PCB material, copper foil type, copper foil thickness, prepreg model, prepreg thickness, core board model, core board thickness, line width and line width spacing are matched with each other. For example, if the thickness of the copper foil of the design parameter is 1mm and the thickness of the copper foil of S001 is 1mm, then the two are matched. If the parameters of both can match, the matched design in the preset database is the same design. It should be noted that some parameters related to the evaluation of insertion loss are directly associated with a certain parameter. For example, the roughness of the copper foil is internally packaged and associated with the type of copper foil. In addition, the material dielectric constant and loss factor are associated with the PP model and thickness, Core model and thickness through the material name. Some parameters are directly associated with a certain parameter, and do not require manual input by the user, which is more convenient and quick. Of course, it is understandable that there are other related parameters, which are not listed here one by one.

[0030] In one embodiment, if Figure 2 As shown, the step S120 may include steps S121-S122.

[0031] S121, matching the design parameters with manufacturing parameters corresponding to manufactured PCBs in a preset database.

[0032] S122: If the matching manufacturing parameters exist in the preset database, the manufactured PCB corresponding to the manufacturing parameters is obtained as the same design.

[0033] In one embodiment, the preset database in this embodiment pre-stores the manufacturing parameters of the manufactured PCB, wherein the manufacturing parameter value is the structure or model parameter of the actual manufacturing of the PCB. The design parameters are matched one by one with the manufacturing parameters of each manufactured PCB in the preset database. Specifically, for example, if there are two manufactured PCBs with design numbers P001 and P002 in the preset database, then the design parameters are matched with the parameters corresponding to P001, and matched with the parameters corresponding to P002. If both parameters can be matched, the matched manufactured PCBs in the preset database are the same design. By matching the design parameters with the manufacturing parameters of the manufactured PCB, the accuracy of the manufacturing parameters of the manufactured PCB is utilized to ensure the accuracy of the evaluated insertion loss capability.

[0034] In one embodiment, if Figure 3 As shown, the step S120 also includes steps S123-S125.

[0035] S123: If there is no matching manufactured PCB in the preset database, then calculating the matching degree between the design parameters and the manufacturing parameters corresponding to the manufactured PCB.

[0036] S124. Sort the manufactured PCBs according to the matching degree from high to low.

[0037] S125, obtaining the manufactured PCB with the highest ranking as the same design.

[0038] In one embodiment, since the preset database pre-stores the manufacturing parameters of manufactured PCBs, and the number of manufactured PCBs is limited, there may be insufficient data in the preset database, which may result in no matching identical design and no result output. In order to avoid the situation where there is no result output due to insufficient data, when the identical design is not obtained in the preset database, the matching degree between the design parameters and the manufacturing parameters is calculated. Specifically, the calculation of the matching degree is to count the specific matching results of each parameter. For example, if there are 10 parameter matches between the design parameters and P001, then the matching degree between the two is 10, and if there are 15 parameter matches between the design parameters and P002, then the matching degree between the two is 15. After the matching degree calculation is performed on all manufactured PCBs in the preset database to obtain the corresponding matching degree, all manufactured PCBs are sorted from high to low in terms of installation matching degree, and the manufactured PCB with the highest ranking is selected as the identical design, thereby ensuring that there is a result output.

[0039] S130, calling the historical insertion loss data of the same design.

[0040] In one embodiment, the historical insertion loss data refers to the insertion loss values ​​obtained by testing PCBs in the past. Each PCB will be subjected to multiple insertion loss tests after manufacturing, and an insertion loss value will be obtained in each test. The insertion loss value is associated with the corresponding PCB and stored in the database. It can be understood that it can be stored in the preset database or in other databases, as long as it can be called. Therefore, after obtaining the same design, the historical insertion loss data corresponding to the same design can be called.

[0041] S140: Process the historical insertion loss data using a preset rule to obtain an insertion loss standard value.

[0042] In one embodiment, the preset rules refer to a series of rules for evaluating the insertion loss of a PCB. The insertion loss standard value is used to indicate the insertion loss capability of the PCB to be manufactured, which is expressed in dB. After obtaining the historical insertion loss data, the historical insertion loss data is processed according to the preset rules to evaluate the insertion loss capability of the PCB to be manufactured and obtain the insertion loss standard value. There are many preset rules for evaluating the insertion loss of a PCB, and the following is a preferred embodiment.

[0043] In one embodiment, if Figure 4 As shown, the step S140 may include steps S141-S142.

[0044] S141 . Process the historical insertion loss data using a first preset algorithm to obtain an average value of the insertion loss data.

[0045] S142: Process the historical insertion loss data and the average value of the insertion loss data using a second preset algorithm to obtain an insertion loss standard value.

[0046] In one embodiment, after obtaining the historical insertion loss data, the historical insertion loss data is first input into a first preset algorithm for processing, and the first preset algorithm is as follows:

[0047]

[0048] Among them, IL n Indicates the nth historical insertion loss data, IL 均值 Represents the average value of insertion loss data. The historical insertion loss data is input into the first preset algorithm to calculate and output the average value of insertion loss data. For example, if the first historical insertion loss data is 10db and the second historical insertion loss data is 20db, then the average value of the obtained insertion loss data is 15db.

[0049] After the average value of the insertion loss data is obtained, the average value of the insertion loss data and the historical insertion loss data are input into a second preset algorithm for processing. The second preset algorithm is as follows:

[0050]

[0051] Among them, IL n Indicates the nth historical insertion loss data, IL 均值 represents the average value of insertion loss data, and σ represents the standard deviation of historical insertion loss data. The historical insertion loss data and the average value of insertion loss data are input into a second preset algorithm to calculate and output the standard deviation of the historical insertion loss data. The obtained standard deviation of the historical insertion loss data is the insertion loss standard value.

[0052] S150, judging whether the insertion loss value meets a preset condition according to the insertion loss standard value, and judging that the PCB to be manufactured meets the insertion loss requirement when the preset condition is met.

[0053] In one embodiment, after obtaining the insertion loss standard value, it is also necessary to use the insertion loss standard value to compare with the PCB insertion loss capability (i.e., insertion loss value) required by the customer. After the insertion loss capability required by the customer is met, it can be determined that the PCB to be manufactured meets the insertion loss requirements. In this way, the evaluation of the insertion loss capability of the PCB to be manufactured before production is completed, so as to evaluate whether the customer's design can meet its own manufacturing capabilities to avoid scrapping and non-delivery. Among them, the preset condition refers to the customer's insertion loss capability requirements for the newly designed PCB. There are many forms of preset conditions, such as the following preferred embodiments.

[0054] In one embodiment, if Figure 5 As shown, the step S150 may include steps S151-S153.

[0055] S151 . Processing the insertion loss standard value and the insertion loss data average value by using a third preset algorithm to obtain an insertion loss evaluation value.

[0056] S152: Determine whether the insertion loss value is less than the insertion loss assessment value.

[0057] S153: If the insertion loss value is less than the insertion loss assessment value, determine that the insertion loss value meets a preset condition.

[0058] In one embodiment, since the insertion loss standard value is a standard deviation value, the insertion loss standard value cannot be directly compared with the PCB insertion loss capability (i.e., insertion loss value) required by the customer. Therefore, the insertion loss standard value needs to be converted accordingly into a value that can be directly compared. In this embodiment, the third preset algorithm is used for conversion, and the third preset algorithm is as follows:

[0059] IL 评估值 =IL 均值 ±3σ

[0060] Among them, IL 评估值 Represents the insertion loss evaluation value. Since the mean ±3σ is usually used to judge the stability of process manufacturing in the manufacturing process, the third preset algorithm in this embodiment is designed as above. If the historical data of a design is less than the mean -3σ, it can meet customer requirements. If the customer's acceptance standard is within the mean ±3σ range, there will be a certain amount of scrap. If it is greater than the mean +3σ, it cannot meet customer needs. Therefore, there are two insertion loss evaluation values ​​in this embodiment, one is the mean +3σ, and the other is the mean -3σ. After obtaining the insertion loss evaluation value, the insertion loss value is compared with the insertion loss evaluation value. If the insertion loss value is less than the insertion loss evaluation value, for example, less than the mean -3σ, it indicates that it can meet customer requirements and meet the preset conditions; for example, if it is less than the mean +3σ, it indicates that it falls within the mean ±3σ range. Although there will be certain defective products in the manufacturing process, it is within an acceptable range and can meet customer requirements and meet the preset conditions; for example, if it is greater than the mean +3σ, it cannot meet customer requirements and cannot meet the preset conditions.

[0061] An insertion loss evaluation method provided by an embodiment of the present invention pre-sets a database for storing relevant parameters of past PCBs, and installs a software tool for users to input design parameters of the PCB to be manufactured. The input design parameters are used to obtain the same design that matches it in the preset database, and the historical insertion loss data of the same design is called to obtain its insertion loss standard value using preset rules. Therefore, whether the PCB to be manufactured meets the insertion loss requirements can be evaluated based on the insertion loss standard value and the insertion loss value. The insertion loss capability of the PCB to be manufactured can be evaluated before its production, so as to avoid unqualified situations when manufacturing the PCB, improve the yield rate of the PCB, and reduce the production cost.
