THIN FILM COIL, CASE ASSEMBLY, NON-CONTACT POWER RECEIVING DEVICE, AND ELECTRONIC DEVICE HAVING THE SAME

摘要

The present invention relates to a thin film coil, a case assembly, a non-contact power receiving device and an electronic device including the same. The thin film coil according to an embodiment of the present invention is a thin film coil disposed at a non-contact power transmitting device for transmitting power wirelessly or a non-contact power receiving device for wirelessly receiving the power transmitted from the non-contact power transmitting device and storing the power in a battery. The thin film coil may comprise: a substrate; a coil pattern including a first coil strip and a second coil strip arranged respectively on both surfaces of the substrate; at least one detour path having both ends connected to the first coil strip, detouring to the other surface of the substrate and partially sharing the second coil strip; contact pads arranged at both ends of the first coil strip and electrically connected to the battery; and at least one connection via arranged at the lower part of at least one among the contact pads and connecting one end of the second coil strip to the at least one contact pad.
