Embodiment Construction
[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0038] During the product design process of the server, the product needs to meet various conditions and various tests, including port signal conduction test, static electricity and conduction test, grounding continuity test and so on.
[0039] In the current existing products, good PCB layout design and good placement layout are usually used to reduce the influence of conducted interference on the server network port, and pass static electricity and conduction...

The application discloses a server mainboard and a design method thereof, and a device. The server mainboard comprises an external port GND, a mainboard GND and an anti-interference element, wherein the attribute of the external port GND is different from that of the mainboard GND, and a current path is formed between the external port GND and the mainboard GND through the anti-interference element; since the external port GND is different from that of the mainboard GND, the server mainboard can pass the electrostatic and conduction testing, and the server mainboard can pass the grounding continuity testing and can effectively eliminate the signal interference between the ports by using the current path formed by the anti-interference element. Compared with the prior art, the product performance of the server mainboard in the invention is greatly improved, the design cost is obviously reduced, and the product competitiveness is improved. The application further correspondingly discloses a server including the above server mainboard.
Description
technical field [0001] The invention relates to the field of server design, in particular to a server, a server mainboard and a design method and device thereof. Background technique [0002] During the product design process of the server, the product needs to meet various conditions and various tests, including port signal conduction test, static electricity and conduction test, grounding continuity test and so on. [0003] Among them, signal port conduction disturbance is a key item in our product design. The main cause of conduction interference at the signal port is the common-mode current, which is not the normal working current signal on the signal port, but caused by some "unintentional" common-mode current. Among them, the conducted interference of the signal port is consistent with the radiated emission caused by the equivalent monopole antenna or dipole antenna model produced by the cable or long-dimension conductor in the product in the radiated interference, bu...
