Problems solved by technology

For the simulation of more complex structures such as vias on the board, wire routing and cross-segmentation, high-precision 3D modeling and simulation methods are usually used to obtain their passive parameters, but this usually takes a lot of time to build. In terms of modeling and simulation, and if you encounter a similar structure, you can only get their passive parameters through modeling and simulation again, which is inefficient

Description

technical field [0001] The embodiments of the present invention relate to a modeling technology of a printed circuit board, and in particular to a method and device for modeling a printed circuit board. Background technique [0002] Printed circuit board (Printed Circuit Board, PCB), also known as printed circuit board, printed circuit board, is an important part of the physical support and signal transmission of electronic products. On the PCB board, there are various wiring forms, such as over Holes, wire wraps and connectors etc. For the simulation of more complex structures such as vias on the board, wire routing and cross-segmentation, high-precision 3D modeling and simulation methods are usually used to obtain their passive parameters, but this usually takes a lot of time to build. In terms of modeling and simulation, and if similar structures are encountered, their passive parameters can only be obtained through modeling and simulation again, which is inefficient. ...
