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.
