The invention discloses a PCB for optimizing the ground plane on the basis of CPU internal wiring, and belongs to the technical field of PCB design. A CPU is provided, and comprises a first type pin and a plurality of second type pins corresponding to the same voltage value. In the CPU, the second type pins are connected with one another. The second type pins include a plurality of adjacent firstpins, a plurality of adjacent second pins and a plurality of discrete third pins. The second pins are adjacent to the first type pins. In the PCB, the first pins are connected with a power supply withthe voltage value, the second pins are connected with the first type pin, and the third pins are idled. According to the technical scheme, the PCB has the advantages that the power supply wiring of the PCB is designed according to the CPU internal wiring, the problem of power supply wiring land division caused by the complicated power supply wiring in the PCB is solved, the PCB complete in function can be easily manufactured through two layers of plates.
Description
technical field [0001] The invention relates to the technical field of PCB board design, in particular to a PCB board for optimizing ground plane based on CPU internal wiring. Background technique [0002] On the current CPU, there are usually multiple types of power supply pins corresponding to the same voltage value, each type of power supply pin has a different pin function, the number of pins for each type of power supply pin is plural, and each type of power supply pin The spacing between multiple pins on the CPU board may be large. The PCB board is provided with pads corresponding to the pins of the CPU. Through the wiring between the pads, the power pins of the CPU are connected to the corresponding power supply. . [0003] In the existing PCB board design process, in the part involving the connection of the CPU power supply, it is usually to connect all the pads corresponding to the power supply pins of the CPU to the corresponding power supply, so that the wiring i...
