Abstract

The invention discloses an anti-interference chip packaging structure, which mainly comprises a pin lead frame, a substrate, a chip and a packaging body. The anti-interference chip packaging structure is characterized in that the substrate is of a concave structure and arranged above the pin lead frame in an inverted mode at the time of package; and the chip is arranged on the top in the substrate in an inserted mode, and the chip is electrically connected with the substrate by adopting a soldering technology. The chip packaging structure disclosed by the invention is simple and convenient for implementation, has good electromagnetic wave radiation resisting capacity and can ensure the high-efficiency operation of the chip; and meanwhile, the chip packaging structure is low in application cost and applied to packaging chips with different specifications and powers.

Description

technical field [0001] The invention relates to a chip packaging structure, in particular to a novel chip packaging structure capable of blocking electromagnetic radiation, and belongs to the technical field of chip packaging. Background technique [0002] In the manufacture of integrated circuits, chips are obtained through the steps of wafer fabrication, forming integrated circuits, and cutting wafers. After the integrated circuit of the wafer is fabricated, the chip formed by dicing the wafer can be electrically connected to the carrier outwardly; wherein, the carrier can be a lead frame or a substrate, and the chip can be wire bonded or covered. The method of crystal bonding is electrically connected to the carrier. If the chip and the carrier are electrically connected by wire bonding, then enter into the manufacturing step of filling the encapsulant to form the chip package. Chip packaging technology is a process technology that wraps the chip to avoid contact betwee...
