Specifically, after the first matching process is not successfully matched, the package name of the element to be created is used as a matching condition to search in the existing standard library, and if an element which is completely the same as the package name of the element to be created is found in the existing standard library, it is indicated that the data corresponding to the element in the existing standard library can be directly copied to be the data of the element to be created, so that the data of the element which is the same as the package name in the existing standard library can be directly copied to be the data of the element to be created, and the material code of the element which is the same as the package name in the existing standard library is modified to be the material code of the element to be created, so that the creation of the data of the element to be created is completed; in addition, if the second matching result is not matched, a third matching process needs to be performed on the element to be created.
On the basis of the foregoing embodiment, this embodiment will specifically describe step 4 in the first embodiment, where step 4 may specifically include:
and 4.1, obtaining parameter data of the element to be created, wherein the parameter data comprises the pin number, the pin interval, the length and the width of the element to be created.

Further, step 4.2 of this embodiment can be implemented, for example, by the following method:
step 4.21, firstly obtaining the pin number of the element to be created;
step 4.22, searching and screening the first element to be screened with the same pin number as the element to be created in the existing standard library, wherein the first element to be screened comprises all elements with the same pin number as the element to be created in the existing standard library;
step 4.23, searching and screening a second element to be screened matched with the pin pitch of the element to be created in the first element to be screened according to the first preset range;
specifically, a first preset range is set first, then an element with a pin pitch meeting the first preset range is selected from the first elements to be screened as a second element to be screened based on the pin pitch of the element to be created, the second element to be screened includes all the elements meeting the first preset range in the first elements to be screened, for example, the first preset range f1 meets-0.1% ≦ f1 ≦ 0.1%, and the pin pitch s of the element to be created is set to 1.27mm, then all the elements between 1.269-1.271mm in the first elements to be screened belong to the second element to be screened, it should be understood that the first preset range can be set according to actual requirements, and this embodiment is not limited in particular.

It should be understood that the first sub-preset range and the second sub-preset range may be set according to actual requirements, and this embodiment does not specifically limit this. In addition, if no element satisfying the second preset range is screened out from the second element to be screened, the element in the second element to be screened needs to be subjected to collision processing based on the second element to be screened.
On the basis of the foregoing embodiment, this embodiment will specifically describe step 5 in the first embodiment, where step 5 may specifically include:
step 5.1, performing angle transformation on the graph of the second element to be screened according to a preset angle to obtain an angle transformation graph, wherein the angle transformation value may be 0 °, 90 °, 180 °, 270 °, for example, please refer to fig. 5a and 5b, fig. 5a is a graph of an original angle of a certain element in the second element to be screened, and fig. 5b is a graph of fig. 5a after the angle transformation of 90 °.
And 5.2, judging whether the pins corresponding to the angle conversion graph and the pad graph of the element to be created collide one by one and obtaining a collision result, if the collision result is one-to-one collision, correspondingly copying data information of the element in the existing standard library as the data information of the element to be created, simultaneously using the material code and the packaging name of the element to be created, if the collision result is not one-to-one collision, extracting a template from the existing standard library, replacing the pin data of the template with the pad data of the element to be created, and simultaneously using the material code and the packaging name of the element to be created.
Specifically, in this embodiment, the positions of the pins in the angle transformation graph and the positions corresponding to the pad graphs of the elements to be created are collided one by one, and if there is an element in the second element to be screened after the angle transformation that can satisfy the effect of collision one by one, it is described that the data of the element can be applied to the data of the element to be created, the data of the element can be directly copied as the data of the element to be created, and meanwhile, the material code of the element is modified into the material code of the element to be created, and the package name of the element is modified into the package name of the element to be created, so that the creation of the data of the element to be created is completed. For example, referring to fig. 5b and fig. 6, if the pin positions marked with the positions a1-a8 in fig. 5b are partially or fully contacted with the positions b1-b8 in fig. 6 in a one-to-one correspondence, the collision success is indicated. In addition, if the components which can be suitable for the components to be created are not screened out from the existing standard library after the processing, a template can be directly extracted from the existing standard library, the size of the pad is obtained from the pad data in the basic database, the pin data of the template is replaced by the pad data, the material code and the package name are modified to be the material code and the package name of the components to be created, and the creation of the data of the components to be created is completed.
In addition, after the creation of the material data of the component to be created is completed each time, the data creation of the next component is performed, and the creation of the component material data is performed through the above steps. And simultaneously, after all the elements on the PCB are established, updating the existing standard library.

| Material coding | Description information | Name of package |
| PN11130 | IC SOP8 | SOP8 |
| PN11131 | CAP_SMC_0805_.085X.055B_MILSPEC | C0805 |

And a second result: if no component with exactly the same package name as the component to be created is found in the existing standard library, step 5 is performed.
Step 5, obtaining pad data of the element to be created from the basic data, and calculating a pin Pitch (Pitch) value of the element to be created, the pin number of the element to be created, and the length and width of the element to be created according to the pad data;
calculating by the pad data of the element to be created: the number of leads of the component to be created was 8, the Pitch (Pitch) of the leads was 1.27mm, and the length and width of the component to be created were 4.9mm and 3.9mm, respectively.
Step 5.1, firstly, taking the pin number 8 of the element to be created as a search condition, searching and screening in the existing standard library, finding out the element with the pin number of 8 in the existing standard library as a first element to be screened,
and 5.2, setting the first preset range f1 to meet the requirements of-0.1% ≦ f1 ≦ 0.1%, and searching the first element to be screened for the element meeting the pin spacing value of 1.269mm-1.271mm according to the pin spacing of the element to be created being 1.27mm, and taking the element in the first element to be screened which is between 1.269mm-1.271mm as the second element to be screened.
And 5.3, setting the first sub-preset range f2 to meet-0.1% ≦ f2 ≦ 0.1%, setting the second sub-preset range f3 to meet-0.1% ≦ f3 ≦ 0.1%, searching for elements meeting the length of 4.899-4.901mm and the width of 3.899mm-3.901mm in the second element to be screened according to the length and the width of the element to be created being 4.9mm and 3.9mm respectively, selecting the element with the length and the width closest to the length and the width of the element to be created as the element for final screening if the element meeting the requirements exists in the second element to be screened, copying the data of the element to be added into the existing standard library, modifying the material code PN11130 and the package name of the element to be created into the SOP8, and creating the data of the element to be created in the existing standard library. If no element with a length and width satisfying the requirements is searched in the second element to be screened, step 6 is performed.
Step 6, after the screening of step 5, obtaining the pattern data of the component in the second component to be screened, for example, as shown in fig. 5a, and the pin Pitch (Pitch) of the component, the length and the width of the component are marked in fig. 5a, and performing an angle transformation of 90 ° on the component pattern, for example, as shown in fig. 5b, and obtaining the pad data pattern of the component to be created, and colliding the angle transformation pattern with the pad data pattern, the result is two types:
