Problems solved by technology

[0005] The staggered parallel wiring method can only eliminate the crosstalk between the two pairs of differential lines facing the upper and lower signal layers, but it cannot eliminate the crosstalk between the other pairs of differential lines on the adjacent signal layer. Therefore, for high-density parallel wiring , this routing method cannot reduce the crosstalk between signal lines

Abstract

The invention provides a main board and a server. The main board adopts a lamination design in a Dual Stripline mode. Two pairs of differential signal lines corresponding to upper and lower two signallayers of the main board adopt an arc ZigZag wiring mode; and a set included angle and separation distance are formed between the two pairs of differential signal lines. The main board and the servercan reduce signal crosstalk between high-density parallel lines in the two signal layers.

Description

technical field [0001] The invention relates to the technical field of printed circuit boards, in particular to a main board and a server. Background technique [0002] With the rise of cloud computing, the development of servers has risen rapidly. In the design of servers, the signal rate is getting higher and higher, and the space design requirements and costs of high-speed signals for motherboards are constantly increasing. In order to reduce the development cost, the Dual Stripline (Dual Stripline) mode is favored by designers in the stacked design. Different from the conventional Stripline (stripline) mode, the characteristics of the laminated design of the Stripline mode are: there is a GND or PWR layer between the signal layer and the signal layer, and the 12-layer board has 6 layers of wiring layers; while the Dual Stripline mode's The characteristics of the stack design are: the two signal layers are designed as adjacent layers, one side of the signal layer is the ...
