[0020] figure 1 It is a schematic diagram of the side mechanism of an embodiment of the present invention.
[0021] Such as figure 1 As shown, a hollow double-sided flexible printed circuit board printed with ACP conductive glue includes a substrate 2, a surface covering film 1, a bottom covering film 3, a copper strip 4 and a copper strip covering film 5, wherein the surface covering film 1 and The bottom cover film 3 is respectively pressed on the surface of the substrate 2 and the ground, the surface cover film 1 is provided with solder joint openings (not shown in the figure), and the bottom cover film 3 is provided with a guide hole 6 to realize conduction on both sides. The strip 4 is pressed on the bottom cover film 3 at the position where wiring is required, and pure glue is pasted between it and the bottom cover film 3. The bottom cover film 3 and the copper strip 4 have a circuit pattern on the surface, and a layer of wire is pressed on the surface of the line. The...
