Abstract

The invention discloses a method for encapsulating a chip with excellent radiating performance. The method for encapsulating the chip mainly comprises the following steps of: a) installing a substrate; b) installing the chip; c) detecting the performance of the chip; d) sealing by using a sealing gum; e) coating a heat-radiating layer; and f) detecting a finished product. The invention discloses the method for encapsulating the chip with excellent radiating performance. In the process of executing the encapsulating method, two encapsulating processes are carried out on the chip; the heat radiating performance of the chip can be effectively improved while a favorable encapsulating performance is ensured; and the high-efficiency operation of the chip is ensured. Simultaneously, in the process of executing the encapsulating method, an external auxiliary radiating device does not need to be added, thus the encapsulating cost is reduced, the encapsulating process is easy to achieve, and the practicality is excellent.

Description

technical field [0001] The invention relates to a chip packaging structure, in particular to a chip packaging method for effectively improving the heat dissipation performance of a chip, and belongs to the technical field of chip packaging. Background technique [0002] Chip packaging technology is a process technology that wraps the chip to avoid contact between the chip and the outside world and prevent damage to the chip from the outside world. Impurities and bad gases in the air, and even water vapor will corrode the precision circuits on the chip, resulting in a decrease in electrical performance. Different packaging technologies differ greatly in terms of manufacturing processes and processes, and packaging also plays a vital role in the performance of the memory chip itself. With the rapid development of optoelectronic and microelectronic manufacturing technology, electronic products are always developing in the direction of smaller, lighter and cheaper, so the packa...
