Abstract

The invention relates to the technical field of a packaging structure, and discloses a lead-free integrated circuit chip packaging structure. The lead-free integrated circuit chip packaging structure comprises a chip packaging body and pins, wherein the number of the pins is twenty-six, the pins are fixedly installed on the front and rear sides of the chip packaging body, both the front and rear sides of the packaging body are provided with safety slots, the number of the safety slots is fourteen, each safety slot is located between the corresponding two pins, the rear side in each safety slot is provided with an inflation hole, and the internal part of each inflation hole is fixedly sleeved with an inflation connector. The lead-free integrated circuit chip packaging structure ensures that there will be no short circuit due to moisture during the operation process through protecting the pins. Meanwhile, rubber has insulation and can prevent a short circuit caused by static electricity generated between the two pins, and the wrapping of an air bag can have an excellent dustproof effect.

Description

technical field [0001] The invention relates to the technical field of package structures, in particular to a leadless integrated circuit chip package structure. Background technique [0002] The packaging of integrated circuit chips refers to the housing used to install semiconductor integrated circuit chips. It plays the role of placing, fixing, sealing, protecting the chips and enhancing the electrothermal performance. To establish a connection, that is to solder the pins on the circuit board, but because each circuit board has different requirements for the length of the pin welding, it is necessary to reserve a longer pin, so on the circuit board with a shorter pin requirement, it will cause The pins are exposed to the air. When working in a humid environment, the moisture in the air will adhere to the pins, causing the pins to short circuit and the chip to burn. At the same time, if the pins are too long, the chip will be suspended. When the circuit board is vibrated,...
