package circuit structure 100, the at least onegroove 11 and the at least onegroove 13 are recessed in opposite direction and spaced from each other along the first direction X perpendicular to the thickness direction, which may improve the heat dissipation efficiency and a temperature equalization effect of thepackage circuit structure 100. Themetal board 10 is electrically connected to the ground wiring, which may avoid electromagnetic interference between the embeddedcomponents 20. Furthermore, the conductive heat sink 45 (45 a, 45 b) may improve the heat dissipation efficiency of thepackage circuit structure 100. In addition, theantenna 41 and the conductive heat sink 45 (45 a, 45 b) are alternately arranged, which may further improve the heat dissipation efficiency and a temperature equalization effect of thepackage circuit structure 100. - It is to be understood, even though information and advantages of the present embodiments have been set forth in the foregoing description, together with details of the structures and functions of the present embodiments, the disclosure is illustrative only; changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the present embodiments to the full extent indicated by the plain meaning of the terms in which the appended claims are expressed.
