More Information
Summary:A wireless charging (WLC) (A4WP) and near field communication (NFC) dual coils PCB structure comprising at least one WLC (A4WP) coil wire having spiral shape and disposed on a printed circuit board (PCB), and a NFC coil wire having spiral shape and disposed on the PCB. At least a portion of the coil wire of the spiral WLC (A4WP) coil is located on a region between two adjacent coil wires of the spiral NFC coil. Therefore, the present invention makes use of spaces of WLC (A4WP) coil such as A4WP or other relevant standards combined with the NFC coil, so that the dual coil of the present invention can reduce the area of the PCB occupied by the electronic device.
