Embodiment Construction

[0024] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] figure 1 A schematic flow chart of the method of the present invention is shown.

[0026] According to the solution of the present invention, a method for designing a main board that reduces radiation effects is provided, such as figure 1 shown, including:

[0027] Drill a ground hole on the ground wire;

[0028] Judging if ground holes are densely arranged on the ground package, whether the ground holes split the reference ground plane or power plane;

[0029] If so, change the ground wire to the ground plane.

[0030] According to an embodiment of the present invention, the method also includes:

[0031] If not, then densely arrange and drill ground hol...

Abstract

The invention provides a main board design method for reducing the irradiation effect. The method comprises: ground holes are drilled in a ground coating wire; whether the ground holes arranged intensively on the ground coating wire segment a reference ground plane or a power plane is determined; if so, the ground coating wire is changed into a ground coating plane; and if not, ground holes are drilled on the ground coating wire intensively. With the method provided by the invention, while the EMC design quality is ensured, the functional design of the product is guaranteed, so that the quality and comprehensive competitiveness of the product are enhanced.

Description

technical field [0001] The invention relates to the field of motherboard design of electronic equipment such as servers and communication products, and in particular to a motherboard design method for reducing radiation effects. Background technique [0002] Electromagnetic Interference (EMI) is a serious and growing form of environmental pollution that can range from annoying crackling of radio reception to potentially fatal accidents caused by the breakdown of safety-critical control systems . Radiation disturbance is the most important form of interference in electromagnetic disturbance. It directly radiates electromagnetic energy in the form of electromagnetic waves, thus causing harm and interference to human body and other equipment. Optimizing the layout design of the motherboard has always been an important means to improve electromagnetic interference and ensure signal quality. [0003] In the layout design of the main board of the server, in order to prevent dire...
