Title:
ANTI-INTERFERENCE CIRCUIT BOARD AND TERMINAL
Document Type and Number:
WIPO Patent Application WO/2020/164494
Kind Code:
A1
Abstract:
Disclosed are an anti-interference circuit board and a terminal. The circuit board specifically comprises a substrate (10), wherein the substrate (10) has a first surface, and the first surface is provided with a first area (14) for placing a magnetometer (2); the substrate (10) is provided with a plurality of circuit layers (11, 12, 15), and the plurality of circuit layers (11, 12, 15) are arranged in a stacked manner, such as the substrate (10) is at least provided with a first functional circuit (20) for generating a magnetic field generated in a first direction, and a second functional circuit (30) for generating a magnetic field generated in a second direction, which are stacked; and when positions of the first functional circuit (20) and the second functional circuit (30) are specifically provided, the following conditions are satisfied: the first area (14) is located at the first functional circuit (20) and the second functional circuit (30) is in a vertical projection of the first surface. Interference suffered by the magnetometer (2) at the first area (14) is compensated by means of the provided first functional circuit (20) and the provided second functional circuit (30), and during arrangement, the first functional circuit (20) and the second functional circuit (30) are located below the magnetometer (2), thereby reducing the occupied area of a surface of an anti-interference circuit board.
