Charging coil module and related product thereof, and preparation method of charging coil module

The invention provides a charging coil module, a related product thereof and a preparation method of the charging coil module. The substrate of the circuit board and the substrate of the charging coil are arranged on the same layer, the first wiring layer and the first coil are arranged on the same layer, and the second wiring layer and the second coil are arranged on the same layer, so that the charging coil and the circuit board form a structure with relatively high integrity. The first coil and the second coil can be directly and electrically connected to the wiring on the circuit board, such as the wiring of the first wiring layer or the wiring of the second wiring layer of the circuit board, so that on one hand, the charging path between the charging coil and the load can be shortened to reduce the link loss, and on the other hand, the BTB connector can be saved to reduce the cost. The structure of the charging coil module is simplified, and the cost input of the charging coil module is reduced.
