Server mainboard and high-speed signal equipment direct connection structure thereof

Abstract

The invention discloses a high-speed signal equipment direct connection structure which comprises a PCB, an installation frame arranged on the surface of the PCB, a plurality of contact pads arrangedon the surface of the PCB, located in the installation frame and connected with high-speed signal lines, and a high-speed signal plug arranged in the installation frame in a pluggable mode. The bottomsurface of the high-speed signal plug is provided with a plurality of signal contacts which are abutted against the corresponding contact pads. Thus, since the signal contacts are installed on the bottom surface of the high-speed signal plug and vertically abut against the contact pads of the high-speed signal lines, stumps can be prevented from appearing when the high-speed signal lines are connected with high-speed signal equipment; meanwhile, the high-speed signal line can be routed in any direction on the PCB, so that the high-speed signal line can be routed in the coverage area of the installation frame, the routing flexibility of the high-speed signal line is improved, and the utilization rate of the area of the PCB is improved. The invention also discloses a server mainboard, and the beneficial effects of the server mainboard are as described above.

Description

technical field [0001] The invention relates to the technical field of PCB, in particular to a direct connection structure of high-speed signal equipment. The invention also relates to a server motherboard. Background technique [0002] With the development of electronic technology in China, more and more electronic devices have been widely used. [0003] A server is an important part of electronic equipment and a device that provides computing services. Since the server needs to respond to and process service requests, generally speaking, the server should have the ability to undertake and guarantee services. According to the different types of services provided by the server, it is divided into file server, database server, application server, WEB server, etc. [0004] IT equipment will be centrally placed in data centers, which contain various types of servers, storage, switches, and a large number of cabinets and other infrastructure. Each IT device is composed of va...

Problems solved by technology

Since the signal pins of the PCIE connector are generally designed to protrude outward, the soldering PIN is generally designed as a rectangle in the PCB, but due to the crowded wiring in the PCB board, most of the high-speed signal lines are routed inside the connector, so the connector The position where the pin is connected to the soldering PIN forms a stub (stub, that is, the redundant part without signal flow), so the high-speed signal line at the connector position in the PCB can only go outside the connector, which limits the routing direction, and the PCB area occupied by this connector position cannot be utilized, and can only be overcome by adding layers or changing the process, resulting in increased costs
