1. A method of manufacturing a plurality of embedded magnetic component devices each including a magnetic core embedded in a cavity formed in an insulating substrate and one or more electrical windings formed around the core, the method comprising:

  • a) preparing a mother base substrate including a row of cavities for respective magnetic cores, each of the cavities including a cavity floor and side walls connected by the cavity floor, and channels formed between the neighboring cavities in the mother base substrate so as to connect the cavities, each of the channels including a channel floor connected to the cavity floor;

    b) applying adhesive to the cavity floor and to one or more of the channels throughout the row of cavities;

    c) installing magnetic cores into the respective cavities so that the magnetic cores are secured in the cavities by the adhesive;

    d) applying an insulating layer to the mother base substrate to cover the magnetic cores and the cavities so as to obtain an insulated mother substrate; and

    e) forming electrical windings, passing through the mother substrate and respectively disposed around each of the magnetic cores;

    whereinthe magnetic cores are secured in the cavities by the adhesive on the cavity floor.
