Title:
CURRENT TRANSMISSION PLATE, CHIP SYSTEM, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/247485
Kind Code:
A1
Abstract:
The present application provides a current transmission plate, a chip system, and an electronic device. The chip system comprises: a motherboard, a chip, and a power supply unit. The motherboard comprises a first surface and a second surface. The chip is located on one side of the first surface of the motherboard. The power supply unit comprises a power supply module and a current transmission plate; the current transmission plate is located on one side of the second surface of the motherboard, and the current transmission plate comprises: a power input end and a power output end. The power input end is electrically connected to the power supply module; the power output end is electrically connected to a power pin of the chip by means of a power via hole of the motherboard; and the current transmission plate is used for converting the voltage output by the power supply module and transmitting current to the power pin of the chip. In the present application, the current transmission plate does not need to avoid a signal via hole and a ground via hole in the motherboard, so that the interference of a power supply path to high-speed signal transmission in a signal line can be reduced or eliminated, and the loss of the power supply path is reduced; moreover, the number of layers of the motherboard can be reduced, so that the process difficulty and cost are reduced.
