1. method for packing that small pieces reconfigure is characterized in that comprising:

  • One first substrate is provided, has a upper surface and a lower surface, and configuration one polymer material layer on its upper surface;

    A plurality of small pieces are provided, and each those small pieces has an active face and a back side, and disposes a plurality of weld pads on this active face;

    Pick and place those small pieces, this active face of each these small pieces is seated on this polymer material layer to cover crystal type;

    One second substrate is provided, has a upper surface and a lower surface, and configuration one two-stage thermosetting cement material on its upper surface;

    Carry out a splice program, this second substrate and this two-stage thermosetting cement material are engaged with the upper surface of this first substrate, so that should coat each these small pieces by two-stage thermosetting cement material;

    Carry out a baking program, so that should be solidified to form a packaging body that solidifies by two-stage thermosetting cement material;

    Break away from this packaging body, this polymer material layer and this first substrate are broken away from this packaging body, with those weld pads on this active face that exposes those small pieces;

    Form the metal wire sections of many fan-outs, an end of each this metal wire sections and those weld pads electrically connect;

    Form a protective layer, with active face and each this metal wire sections that covers each these small pieces and the other end that exposes each this metal wire sections;

    Form a plurality of electric connection elements, those other ends that electrically connect element and those metal wire sections are electrically connected;

    AndCut this packaging body, to form a plurality of packaging bodies independently separately.
