Problems solved by technology

[0008] However, the formation of the extended portion 11a of the above-mentioned printed circuit board 11' will interfere with the airflow driven by the fan wheel 13' when it rotates. If the airflow is disturbed, noise will be generated, which will further affect the cooling fan installed. The quality of electronic products
At the same time, because the extension part 11a is extended outward, a predetermined distance needs to be maintained between the blade 132' and the control chip 110', which is not conducive to the reduction of the overall height of the existing cooling fan, and cannot meet the thinning requirements of electronic products. needs
[0009] Moreover, the aforementioned existing heat dissipation fan still needs to arrange the printed circuit board 11' between the hub 130' of the fan wheel 13' and the base 120' of the housing 12', resulting in the thickness of the printed circuit board 11' still affecting heat dissipation. The overall height of the fan, without further thinning the cooling fan

Abstract

The invention discloses a semiconductor packaging component with a cooling fan and a manufacturing method and a stacking structure thereof. The semiconductor packaging component with the cooling fan comprises a substrate, an electronic element, a packaging rubber body and a fan unit, wherein the substrate is provided with a first surface and a second surface, the first surface is provided with a fan arrangement area, the fan arrangement area of the substrate is provided with an open hole and a ventilation hole penetrating through the substrate; the electronic element is arranged on the first surface and around the fan arrangement area and is electrically connected with the substrate; the packaging rubber body is formed on the electronic element and the first surface of the substrate and is provided with a packaging rubber body opening for the exposure of the fan arrangement area; and the fan unit is arranged in the packaging rubber body opening and is electrically connected with the substrate. Since the electronic element is arranged on the part of the substrate outside the fan arrangement area, when the fan unit operates normally, heat produced by the electronic element can be effectively dissipated and can be prevented from being damaged as a result of overheating, and the overall height of the fan unit can be reduced.

Description

technical field [0001] The present invention relates to a semiconductor package and a manufacturing method thereof, in particular to a semiconductor package with a cooling fan and a manufacturing method thereof. Background technique [0002] For example, the circuit board of the main board (Main Board or Mother Board) is provided with a plurality of electronic components such as a central processing unit or a graphics card (Electronic Components) and the electrical circuits (Conductive Circuits) used to electrically connect the electronic components, The electronic components will generate heat when they function. If the generated heat is not removed from the electronic product on which the circuit board is installed, the electronic components will fail due to overheating. This problem is increasing with the increasing functional requirements and processing speed. Faster electronic products are more important, because the improvement of functions and processing speed means t...
