Abstract

The present application discloses a layout design method of a gold finger of a board and a server board. The design method includes: according to the type of the GND pin on the gold finger of the board, the space between the gold finger and the GND via on the board, Set the number of GND vias interconnected with GND pins to maximize the number of GND vias interconnected with GND pins; combine and interconnect GND pins and all GND vias that match GND pins to form a signal return path ;In a signal return path, place all GND vias close to their matching GND pins, so that the length of a signal return path is the shortest. Through the design method in this application, the degree of attenuation during high-speed signal transmission can be greatly reduced, and the signal return path can be effectively optimized, thereby avoiding signal insertion loss waveforms, near-end crosstalk frequency domain waveforms, and far-end crosstalk frequency domain waveforms at high A resonance point is generated in the frequency range, which is conducive to improving the quality of signal transmission, thereby improving the stability of the entire system operation.

Description

technical field

[0001] The present application relates to the technical field of server board design, in particular to a design method of a gold finger layout of a board and a server board. Background technique

[0002] In the field of server board design, with the increase of the high-speed interface rate, the transmission quality of high-speed signals in the channel link has attracted people's attention, and the layout design of the golden finger of the server board closely affects the transmission of high-speed signals Therefore, it is an important issue to study the wiring design of the layout at the golden finger of the server board.

[0003] For the current wiring design method of the golden finger of the server board, please refer to figure 1 . Depend on figure 1 It can be seen that the current layout design method for the gold finger of the server board is mainly: each GND pin of the gold finger corresponds to a GND pin, and the GND pin of the gold finger and the ...
