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.
