technical field

The invention belongs to the field of component package model data management, and discloses a component package model data management method based on a security strategy.

Background technique

Packaging is the basic unit of PCB design. All PCB components have their own packaging, and a little packaging error may cause problems in the entire design or even scrap the product, wasting a lot of cost.

The PCB packaging model data management method in the industry is generally linear structure management, that is, the first-level index maps a package library, and the first-level index is the library information record. This management method may cause unverified packages to be used by multiple products, which has greater security. Hidden dangers, and the data management of the package model integrated into the system also needs to be filled in manually, and the information is not directly extracted from the entity library, which is prone to human negligence. .

With the development of the electronics industry, components are becoming more and more integrated and miniaturized. There are also various types of components and huge data types. The traditional one index plus one package library management method has a greatly increased error rate, and manual management is very difficult. Packaging The way model data is managed is in dire need of improvement.

Upload the updated temporary packaging resume;

Update the original official packaging resume with the updated temporary packaging resume to obtain a new official packaging resume;

According to the library life cycle of the new official package resume, judge whether there are PCB packages in the PCB temporary library that need to be added to the PCB official library or PCB unverified library, and determine whether there are PCB packages that need to be added to the PCB official library in the PCB unverified library.

Update the original official packaging resume with the updated temporary packaging resume, and get the new formal packaging resume including:

Determine whether the index of each PCB package in the new official package resume is correct;

If any information in the index of a certain PCB package is wrong, add the error to the error report, prompting that the information of the PCB package is wrong, and replace the new official package resume with the index of the PCB package in the original official package resume The index of the PCB package;

If the PCB package is a newly added PCB package, delete the entry where the PCB package is located in the new official package resume.

The method also includes:

A query instruction for querying a certain library information or a certain life cycle of the target PCB package is received; the target PCB package is a PCB package of a formal PCB library or a PCB unverified library;

According to the query command, query the corresponding information of the target PCB in the latest official package resume.
