Wiring system and wiring method of ground protection line in pcb board

Abstract

The invention provides a wiring system and a wiring method for ground protection lines in a PCB board. The wiring method includes: selecting the signal line to be protected; reading the design specification of the signal line, which includes the line width and safety of the signal line Spacing; widen the line width and safe spacing of the signal lines in the design specifications; lay out the signal lines according to the design specifications and widening settings; after the wiring is completed, set the callback settings for the signal lines to restore the line width and Safe spacing; automatically lay ground wires so that the signal wires are surrounded by ground wires. Compared with the prior art, the present invention sets certain characteristics of the signal line before wiring, and finally automatically lays the ground line, which can ensure that the surrounding of the signal line can be surrounded by the ground line, and implement good ground protection for the signal line , the entire wiring is automatically completed without rework, simple, fast and efficient, which can save the time of board making and design, and significantly improve the work efficiency of designers.

Description

technical field [0001] The invention belongs to the field of printed circuit boards, in particular to a wiring system and a wiring method for ground protection lines in a PCB board. Background technique [0002] With the development of technology, the lines on the PCB are getting thinner and denser. [0003] When designing a PCB, some important signal lines, such as clock lines, radio frequency lines, reset lines, etc., often need to be ground-covered. At present, HDI boards, especially mobile phone motherboards, have a high density and squeeze space, and many important signal lines are routed by the way. There are two ground wires on both sides, in case the ground wire cannot be wrapped after the final board design is completed, but in many cases due to space reasons, the ground wire will be squeezed out during the drawing process of the board, and it needs to be redrawn, even if the ground wire is locked in advance Finally, due to the high density and insufficient space, ...
