Abstract
The present disclosure provides a multi-function charging printed circuit board by forming a short-range antenna and multiple charging coils on multiple layers, wherein the short-range antenna and at least one charging coil is integrated on a single layer. One or more temperature-detecting units are disposed on the charging side of the charging printed circuit board for effectively dissipating heat and avoiding over-temperature accidents. A ferrite sheet is attached to the bottom side of the wireless charging printed circuit board for improving the efficiency of wireless charging.
