PCB design method and system for improving stability of power supply connection of server, and PCB board

Abstract

The present invention proposes a PCB design method and system for improving the stability of the power supply connection of a server,, and a PCB board. The method is characterized in that: at the high-current connection of the PCB board, the power attribute of the adjacent laminated power supply surface of the PCB board is modified from the repulsion to the same, and a plurality of VIAs are arranged around the high-current connection to balance the current density and dissipate the heat; in the same stack, both the distance between the power supply surface of the PCB board at the high-currentconnection and the adjacent power supply surface, and the distance between the power supply surface of the PCB board at the high-current connection and the part are 100 mils; and the diameter of the screw gasket is smaller than the diameter of the bare copper on the power supply surface. Based on the design method, the present invention further provides a design system and a PCB board. According to the technical scheme of the present invention, the short circuit caused by the screw scratching the PCB can be effectively avoided; even if the PCB is scratched and damaged, the properties between different stacks are the same, no short-circuit current will occur, and further burnout and other problems will not occur; and product stability and quality of a high-performance server can be effectively improved.

Description

Technical field [0001] The invention belongs to the technical field of server power supply, and particularly relates to a PCB design method and system, and a PCB board for improving the stability of server power supply connection. Background technique [0002] In recent years, with the development of cloud computing, big data, artificial intelligence and deep learning technology, and the development of high-performance computing in non-scientific fields, high-performance computing servers have achieved explosive growth. With the continuous expansion of the Internet scale and the favorable era of Internet+, the research and development of key technologies of the Internet of Things and application demonstrations in key areas have been promoted, the construction of cloud computing big data service platforms has been strengthened, and the demand for high-end servers has been greatly increased. At the same time, big data technology is driven by advanced data collection technology and ...

AI Technical Summary

Problems solved by technology

However, the screws are easy to damage the PCB board. The power properties of different stacks of the PCB itself are different. After the PCB is damaged, a short circuit between different power properties will occur, resulting in PCB burnout and other problems that seriously affect the product stability and product quality of high-performance servers.
