Method and device for obtaining device packaging types

Abstract

The invention discloses a method for acquiring the encapsulation types of a device. The method comprises acquiring the types of technology of a printed circuit board (PCB), and searching and determining the encapsulation types of the device arranged on the PCB in the corresponding relation of the types of technology and the encapsulation types of the device according to the acquired types of technology. The invention also discloses a device for acquiring the encapsulation types of the device. By adopting the invention, the process route of the PCB can be acquired in the process of designing the schematic diagram and the encapsulation types of the device can be determined according to the acquired process route, thus satisfying the need of PCB process design and improving the efficiency and the quality of the PCB process design.

Description

technical field [0001] The invention relates to printed circuit board technology, in particular to a method and device for obtaining device packaging types. Background technique [0002] Traditional electronic design automation (EDA, Electronic Design Automatic) software tools do not consider the process requirements of printed circuit board (PCB, printed circuit board) when acquiring the package type of the device. With the increasingly complex PCB processing technology, when designing and developing electronic products, it is necessary to determine the PCB process route according to the PCB processing process, and then determine the packaging type of the device according to the determined process route. The process route can also be called the process type. . [0003] At present, using BS, an electronic design software of MENTOR company, combined with a data management system (DMS, Data Manager System), the package type of the device can be determined according to the PCB...

AI Technical Summary

Problems solved by technology

[0004] In PCB design, devices often need to change different package types according to the requirements of the process route, including changing the relative position between the pads, etc. Through the design method of BS and DMS combination, although the size and shape of the pads can be obtained according to the process route Different package types, but other factors in the device package type cannot be changed, such as the relative position between pads, etc., which cannot fully meet the needs of PCB design

[0005] In addition, in the existing EDA software tools, usually the same package type is saved in the same file path, while in the combined software tool of BS and DMS, pads with the same package but different sizes and shapes need to be saved in different file paths In , the device package type is obtained through different file paths, this method is not applicable to other EDA software tools

Therefore, the existing methods for designing process routes for PCBs have a small scope of application.
