The peripheral electronic element is an RLC electronic element and is arranged on the second surface of each substrate; the two substrates and the respective resistance, inductance, capacitance (RLC) electronic elements, the embedded transformer and the filter are symmetrically arranged by taking a central line between the two first surfaces as an axis, so that the RLC electronic elements are far away from the central line, and signals on the respective RLC electronic elements of the two substrates are kept from interfering with each other. The RLC electronic elements are arranged at the position far away from the central line of the first surface, so that the RLC electronic elements of the two substrates are far away from each other, signals on the RLC electronic elements are not interfered with each other, and the working efficiency of the embedded device is improved.

Wherein the horizontal projections of the transformer, the filter and the RLC electronic component on the midline between the two first surfaces are completely overlapped, and the centers of the projections of the two are coincident. By arranging the transformer, the filter and the RLC electronic element to be completely overlapped in horizontal projection on the middle line between the two first surfaces, all the assemblies can be located on the same horizontal line, the arrangement rule among all the assemblies is compact, the size of the embedded device is favorably reduced, and the production cost is reduced.
