Abstract

The invention discloses a circuit board and an electric connector with the same. The circuit board is provided with a first circuit layer, a first insulating layer, a second circuit layer, an insulating substrate, a third circuit layer, a second insulating layer and a fourth circuit layer sequentially from top to bottom in a stacked mode. A first metal route and a second metal route are formed onthe first circuit layer and the second circuit layer correspondingly, and a first differential route pair is constituted. A third metal route and a fourth metal route are formed on the third circuit layer and the fourth circuit layer correspondingly, and a second differential route pair is constituted; and the two metal routes constituting each differential route pair correspond in the up-down direction and are different in width, and thus crosstalk between signals of the adjacent differential pairs can be lowered.

Description

technical field [0001] The invention relates to the technical field of connectors, in particular to a circuit board capable of transmitting differential signals and an electrical connector with the circuit board. Background technique [0002] Differential Signal (Differential Signal) is a signal transmission technology, which is more and more widely used in high-speed circuit design. The most critical signal in the circuit often adopts a differential structure design, and the pair carrying the differential signal The lines are called differential traces. [0003] In the actual circuit board (PCB) layout, the traditional differential routing structure cannot effectively reduce the crosstalk noise between adjacent differential pairs, which will affect the signal integrity of the high-speed system. [0004] Therefore, it is necessary to provide a new circuit board, which adopts a new wiring method to solve the problems existing in the prior art. Contents of the invention ...
