Problems solved by technology

[0002] In some occasions, the heating power of the chip causes the temperature of the chip to rise, which in turn leads to a decrease in the life of the chip. In order to reduce the temperature of the chip, people usually attach a heat sink on the surface of the chip to dissipate heat. Exposure to the air for a long time, more and more dust will accumulate on the surface of the heat sink, which will reduce the heat dissipation efficiency of the heat sink

Abstract

The invention relates to a chip packaging and radiating mode. A chip packaging structure prepared through the mode comprises a chip main body, a macromolecule packaging material layer and at least two thermal bimetallic strip assemblies. The chip packaging and radiating mode has the beneficial effects that the radiating surface area is increased when chips emit heat, and the radiating surface area is reduced when the chips do not emit heat, so that dust accumulated on the surfaces of the chips is reduced, and the radiating efficiency of the packaging structure is improved.

Description

technical field [0001] The invention relates to the technical field of chip packaging, in particular to a heat dissipation method for chip packaging. Background technique [0002] In some occasions, the heating power of the chip causes the temperature of the chip to rise, which in turn leads to a decrease in the life of the chip. In order to reduce the temperature of the chip, people usually attach a heat sink on the surface of the chip to dissipate heat. In the long-term exposure to air, more and more dust will accumulate on the surface of the heat sink, which will reduce the heat dissipation efficiency of the heat sink. Contents of the invention [0003] The invention provides a new heat dissipation mode for chip packaging, so that when the chip generates heat, the heat dissipation area increases, and when the chip stops working, the heat dissipation area decreases, thereby reducing the accumulation of dust on the surface of the heat sink. [0004] In order to achieve t...
