The advantages of more fully understanding the embodiment of the utility model and its various aspects.Below in an example, it provides real in detail below
The purpose for applying mode is easy for becoming apparent from thorough explanation to the content of the utility model, rather than to the limit of the utility model
System.
In the present invention, it is front, i.e. first surface 11 with the surface of the setting conductive sheet of FPC plates and wiring, and
Opposite surface is the back side, i.e. second surface 12 with the front of FPC plates.
Embodiment
With reference to Fig. 2 and Fig. 3, the utility model provides a kind of FPC using composite material reinforcement, which includes being located at
Conductive sheet, electronic component and the reinforcing member for being set to FPC backs in FPC plates front 11, the conductive sheet are electrically connected with interfacing part
It connects, conductive sheet is, for example, pad, golden finger etc., and in the present embodiment, conductive sheet is mainly pad 40, and electronic component is inductance
Element 30, but electronic component can also be other electron component.
The FPC plates of the utility model provide a kind of reinforced structure, can while ensureing reinforcing support intensity not shadow
Ring the antenna performance of inductance element.Draw as shown in Fig. 2, the front of the FPC plates of the utility model, i.e. first surface 11 include plating
Line, the inductance element 30 being connect with electroplate lead wire and pad 40, wherein two inductance elements 30 are arranged side-by-side, and pad 40 surrounds
