Abstract: An anti-interference circuit board and a terminal, where the anti-interference circuit board includes a substrate having a first surface and a first region for placing a magnetometer is disposed on the first surface. A plurality of circuit layers are disposed in the substrate in a stacked manner. The first functional circuit and the second functional circuit are disposed to compensate for interference to the magnetometer in the first region, and during disposing, the first functional circuit and the second functional circuit are located below the magnetometer to reduce an occupied surface area of the anti-interference circuit board.

Abstract: An anti-interference circuit board and a terminal are provided. The circuit board specifically includes a substrate (10). The substrate (10) has a first surface, and a first region (14) for placing a magnetometer (2) is disposed on the first surface. A plurality of circuit layers (11, 12, 15) are disposed in the substrate (10), and the plurality of circuit layers (11, 12, 15) are disposed in a stacked manner. For example, at least a first functional circuit (20) that is configured to generate a magnetic field in a first direction and a second functional circuit (30) that is configured to generate a magnetic field in a second direction are disposed in a stacked manner and are disposed in the substrate (10). When positions of the first functional circuit (20) and the second functional circuit (30) are specifically disposed, the following is met: the first region (14) is located in vertical projections of the first functional circuit (20) and the second functional circuit (30) on the first surface. It can be learned from the foregoing descriptions that the first functional circuit (20) and the second functional circuit (30) are disposed to compensate for interference to the magnetometer (2) in the first region (14), and during disposing, the first functional circuit (20) and the second functional circuit (30) are located below the magnetometer (2), to reduce an occupied surface area of the anti-interference circuit board.
