Abstract

Provided are a semiconductor packaging structure and a heat dissipation member thereof. The semiconductor packaging structure comprises a bearing member having a semiconductor assembly and a heat dissipation member so that an accommodation space is formed between the heat dissipation member and the bearing member to make the semiconductor assembly positioned in the accommodation space. The heat dissipation member has a guide channel which is provided with a through hole and a recessed structure. The though hole is communicated with the accommodation space. The recesses structure is connected with a hole wall of the through hole, such that if a packaging rubber body is formed in the accommodation space and the recessed structure to wrap the semiconductor assembly, excessive glue is prevented from flowing around the through hole, and the heat dissipation efficiency can be improved.

Description

technical field

[0001] The invention relates to a semiconductor package structure, in particular to a semiconductor package structure with a heat sink and the heat sink. Background technique

[0002] In the heat dissipation technology of the current semiconductor packaging structure, heat sinks are often arranged outside the structure, so that the heat sink can be used as a heat dissipation path by contacting the heat sink with air, such as figure 1 The semiconductor packaging structure 1 shown has a packaging substrate 10, a semiconductor component 11 disposed on the packaging substrate 10, a heat sink 12 disposed on the packaging substrate 10 to cover the semiconductor component 11, and covering the semiconductor component 11. The encapsulant 13 on the sides of the semiconductor component 11 and the heat sink 12 . Wherein, the heat sink 12 has a central through hole 120 , so that the encapsulant 13 can be filled into the inner side of the heat sink 12 through the central ...
