Abstract

The invention provides a chip packaging method with electromagnetic shielding function, comprising the following steps: preparing a heat sink with insulating bumps, and bonding metal pins on the insulating bumps; bonding a chip module on the heat sink with The side of the insulating bump; use the wire harness to electrically connect the pins of the chip module and the metal pins on the insulating bump; solder the shielding shell to the end of the insulating bump away from the heat sink, and plastic-encapsulate the shield shell and the heat sink to obtain Chip finished product. The invention is used to improve the production and preparation process in the chip manufacturing process, so that the chip can have the electromagnetic shielding function, thereby improving the product performance, and reducing the equipment can not work normally or malfunction caused by electromagnetic interference during the working process of the chip. Case.

Description

technical field [0001] The invention relates to the technical field of chip packaging, in particular to a chip packaging structure and packaging method with electromagnetic shielding function. Background technique [0002] With the popularization of electronic equipment, the demand for chips used to realize circuit control or specific functions has increased significantly; the production volume has also increased, but the product performance is uneven; for example, the existing chips are in the actual use process. It does not have the electromagnetic shielding function, so that the chip is very prone to failure and the electronic equipment cannot work normally; therefore, there is a lack of a chip packaging process that can have the electromagnetic shielding function. SUMMARY OF THE INVENTION [0003] The invention provides a chip packaging structure and packaging method with electromagnetic shielding function, which are used to improve the production and preparation proce...
