Example Embodiment
[0041] Method embodiment 2: A method for manufacturing a wireless charging receiving terminal. In this embodiment, a planar coil is fabricated on a single-sided FPC, including the following steps:
[0042] A. Processing of receiving coil
[0043] A1. Plane coils and inner and outer lead wires are processed on the single-sided flexible circuit board FPC. The outer lead wires are directly arranged at the lead-out position and extend outward from the outermost circle of the planar coil (such as Figure 4 Shown);
[0044] A2, cut the three edges where the inner lead wire and the coil are not connected;
[0045] A3. Insulate the part of the cut inner lead wire in contact with the coil body;
[0046] A4. Fold the insulated inner lead wire to the surface of the coil. The bending angle can be any angle as needed, preferably 90° or 45°, so that the direction of the inner and outer lead wires are the same;
[0047] B. Using traditional technology to produce magnetic shielding sheet with at least o...
