Abstract
The invention provides a printed circuit board and a coupling subassembly of the printed circuit board. The coupling subassembly comprises at least one printed circuit board and a connector. The printed circuit board comprises a hard plate body, at least one connection section and a signal wire, wherein the connection section is the same as the plate body in material and extends and bends outwards along the plate body, and the signal wire extends to the end part of the connection section along the plate body and is used for transmitting a high-speed signal, and the connector is correspondingly connected with the end part of the connection section. Therefore, the connection section in the printed circuit board is changed into a bent state, and the connection of the printed circuit board and the other circuit boards is facilitated. Meanwhile, a connector with a long signal pin is avoided, and therefore, the problems of serious crosstalk and damaged signal integrity caused by an extra-short high-speed signal wire inside the connector are reduced.

Technical field
The present invention relates to a kind of printed circuit board (PCB) and printed circuit board (PCB) coupling assembling.
Background technology
Along with the time delay of data-signal is more and more less, the performance of electronic equipment promotes rapidly.For example, third generation PCI-E signal rate is 8Gbps, and third generation SAS signal rate can reach 12Gbps.Yet the transmission rate of signal is higher, and the cross-interference issue between signal is just more serious, and for fear of the cross-interference issue between high speed signal, HW High Way can keep wider spacing when wiring.Yet when high speed signal by connector the time, because the restriction of width, the spacing of HW High Way in connector must shorten, and crosstalks thereby produce.
For example, when printed circuit board (PCB) is connected with other circuit boards are vertical, need to utilize rigging-angle connector to connect.As everyone knows, holding wire length in the rigging-angle connector is greater than the holding wire length in the in-line connector, and this is so that crosstalking between the high speed signal that transmits in rigging-angle connector must be than crosstalking seriously between the high speed signal that transmits in in-line connector.Similarly, stacking connector also is like this.
Although high speed connector has in the market been considered the cross-interference issue of connector inside, between the connection pin, done the ground shielding, but along with following signal rate is more and more higher, the transmission rate of high-speed transfer holding wire may reach 20Gbps, 30Gbps, 40Gbps even higher only relies on the ground shielding of connector inside can't better solve above-mentioned cross-interference issue.Therefore, need to improve the structure of existing printed circuit board (PCB), to reduce the cross-interference issue of high speed signal in connector.
