Patent ID: 8619428

Claim:
An electronic package structure comprising: a substrate including a heat-dissipating plate and a circuit board partially covering the heat-dissipating plate; a first electronic element disposed on the heat-dissipating plate and coupled to the circuit board; and a second electronic element disposed on the circuit board and coupled to the circuit board, wherein the substrate further comprises a plurality of conductive nodes, the circuit board has a circuit layout and defines an opening extending from the first surface of the circuit board to the second surface of the circuit board opposite the first surface, the heat-dissipating plate is disposed on the second surface of the circuit board, and the location of the heat-dissipating plate corresponds to that of the opening so that the heat-dissipating plate covers at least a part of the opening, the conductive nodes are disposed on the circuit board, coupled to the circuit layout, and used for being coupled to an external electronic device, the first electronic element is disposed in the opening and coupled to the circuit layout, and the second electronic element is coupled to the circuit layout, wherein the amount of heat produced by the first electronic element is larger than the amount of heat produced by the second electronic element, and wherein the second electronic element is disposed on the first surface of the circuit board, and the conductive nodes are disposed on the second surface of the circuit board, and wherein the substrate further includes a plurality of the thermal vias, each thermal via comprising: a through-hole extending from the first surface of the circuit board to the second surface of the circuit board; and a heat-dissipating material being filled in the through-hole, and the electronic package structure further comprises a third electronic element disposed on the first surface and coupled to the circuit layout, wherein the amount of heat produced by the third electronic element is between the amount of heat produced by the first electronic element and the amount of heat produced by the second electronic element and, the location of the third electronic element corresponds to that of the thermal vias so that the heat from the third electronic element is conducted from the first surface to the second surface through the heat-dissipating material.
