Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.
Reference picture 1, the conducting orifice device of a kind of FPC, by first line plate 1, the base being sequentially overlapped from top to down
Material layer 2 and the second wiring board 3 are formed by press pressing, and the wiring board 3 of first line plate 1 and second is by copper or copper alloy system
Into substrate layer 2 is made up of insulating materials, and the wiring board 3 of first line plate 1 and second is double-faced flexible wiring board, the First Line
The wiring board 3 of road plate 1 and second is provided with conducting wire.It is provided with and leads on the first line plate 1, the wiring board 3 of substrate layer 2 and second
Through hole 8, metal level 9 of the inwall provided with connection first line plate 1 and the second wiring board 3 of via hole 8, the metal level 9 is copper
