Problems solved by technology

But there are also unavoidable shortcomings: the production cost is greatly increased, and the accuracy of back drilling is affected; for example, if the back drilling is not accurate, the entire circuit board may be short-circuited, which will lead to board burning.

Abstract

The invention discloses a Rack server design method based on research for an influence of stub resonance on signal integrity. The method comprises the following steps that: firstly, comparing the influence of a via hole aperture on a signal under situations that a stub is in the presence and the stub is in the absence; and then, according to a via stub influence situation which needs to be considered when a PCB (Printed Circuit Board) route needs to change layers, establishing a Rack server. By use of the method, according to a via hole equivalent circuit model under the situations that the stub is in the presence and the stub is in the absence, the influence of the stub resonance on a whole system circuit board can be accurately obtained, the judgment of the influence of Layout for the via stub in whole circuit design can be greatly lowered, and therefore, the integral operation reliability of the Rack server system can be greatly improved during the operation of the whole circuit board.

Description

technical field [0001] The invention relates to a Rack server design method based on research on the influence of stub resonance on signal integrity, and belongs to the technical field of cloud server circuit board design. Background technique [0002] With the continuous expansion of the application scope of cloud computing and the emergence of online shopping, online approval, and online banking payment, many businesses in people's work and life are showing the development trend of informationization. The computing performance requirements of network servers are increasing, and the concept of cloud computing has also emerged, and the new concepts of government affairs cloud, health cloud and taxation cloud have been initially formed. With the rise and development of cloud computing technology, as a unit-cabinet system in the traditional computer room, it is required that the data processing capabilities of the server computing nodes deployed in the cabinet are getting stro...
