Problems solved by technology

The daughter card is usually an x8 or x16 gold finger board. When designing such a daughter card adapter board, due to the placement of the SMA, it is often impossible to achieve all the short trace lengths.
[0003] In the existing technology, for X8 and X16 Goldfinger sub-card adapter boards, it is usually designed with a longer wiring length, such as 5 inches, but the actual wiring is often around 3 inches; system passive channel test, this type of sub-card adapter board The wiring cannot achieve full coverage of 3 inches, and the length is inaccurate, which affects the SI analysis results

Abstract

The invention provides a golden finger switch board-adopted routing path traversal method, a switch board and terminal equipment. According to the method, board cards designed in blocks are put through an SMA, so that 16 pairs of differential lines of an X8 golden finger are all led out via 3inch; and meanwhile, 16 pairs of differential lines are added to be all led out via 4.5inch, so that more test verification conditions are covered. Through the SMA, the putting is switched between top and bottom, so that full coverage of relatively short routing of folder finger type sub-card switch boardsis realized, the length is correct and SI analysis results are not influenced.

Description

technical field [0001] The invention relates to the technical field of server systems, and in particular to a method for traversing the length of wires using a golden finger adapter board, an adapter board and a terminal device. Background technique [0002] In the server system, when performing full-link channel performance analysis on the main board through the riser card and then to the sub-cards such as SAS card / Raid card / network card, it is necessary to design the main board adapter board and the sub-card adapter board. The daughter card is usually an x8 or x16 gold finger board. When designing such a daughter card adapter board, due to the placement of the SMA, it is often impossible to achieve all the short trace lengths. [0003] In the existing technology, for X8 and X16 Goldfinger sub-card adapter boards, it is usually designed with a longer wiring length, such as 5 inches, but the actual wiring is often around 3 inches; system passive channel test, this type of su...
