Abstract:
Disclosed are a wireless charging back shell assembly and an electronic device. The wireless charging back shell assembly comprises a back shell, a wireless charging coil, a first bonding pad, a second bonding pad, a first FPC transmission line and a second FPC transmission line, wherein the wireless charging coil is formed on the surface of the back shell by means of a laser engraving process; the wireless charging coil is provided with an inner port, which is located on the inner side of the coil, and an outer port, which is located on the outer side of the coil; and the inner port is electrically connected to the first bonding pad by means of the first FPC transmission line, and the outer port is electrically connected to the second bonding pad by means of the second FPC transmission line. In the wireless charging back shell assembly disclosed in the present application, the wireless charging coil is formed on the surface of the back shell by means of the laser engraving process, such that the heat dissipation effect of the assembly is good; moreover, compared with an existing wireless charging module, a TEP protective film part can be removed, such that the overall thickness of a wireless charging module is reduced; and the flexibility of connection between the wireless charging coil and a mainboard can be improved by means of the provision of the first FPC transmission line and the second FPC transmission line.
