Description

Technical Field

[0001] The present invention relates to the technical field of carriage cleaning, in particular to a chip packaging structure. Background Art

[0002] As the core component of modern technology, chips play a key role in many fields. Chips are tiny integrated circuits made of semiconductor materials. They contain a large number of transistors, resistors, capacitors and other electronic components. Through advanced manufacturing processes, these components are integrated on an extremely small chip, achieving a high degree of functional integration and performance improvement. Chips have the advantages of small size, light weight, low power consumption and powerful performance. They are widely used in computers, communications, consumer electronics, automobiles, medical and other fields. In computers, chips are the core of processors and memory, which determines the computer's computing speed and storage capacity. In the field of communications, chips are used in mobile phones, base stations and other equipment to achieve high-speed data transmission and communication functions.

[0003] Chip packaging refers to the shell used to install semiconductor integrated circuit chips. It not only plays the role of placing, fixing, sealing, protecting the chip and enhancing thermal conductivity, but also serves as a bridge to communicate the internal world of the chip with the external circuit.

[0004] However, the existing processing equipment has the following deficiencies:

[0005] Prior art, such as CN116153868A, the present invention provides a chip packaging structure, including a chip seat, a chip, multiple pins, multiple wires and a packaging colloid, the chip seat has multiple first openings penetrating the chip seat, the chip is arranged on the chip seat through a die-bonding layer, the multiple pins are respectively arranged around the chip seat, the multiple wires electrically connect the chip and the multiple pins, the packaging colloid covers the chip, the multiple wires, the chip seat and a portion of each pin, the packaging colloid has multiple second openings, each second opening is connected to one of the multiple first openings, and the multiple first openings and the multiple second openings are located in the coverage area of ​​the chip and expose the die-bonding layer. The chip packaging structure of the present invention has the effect of reducing the interface stress between the chip and the die-bonding layer, avoiding delamination of the chip, and providing a pressure release path for water vapor evaporation to reduce the interface stress between the chip and the die-bonding layer, avoiding delamination of the chip.

[0006] In daily work, the inventors have found that in the process of fixing and packaging the pins and chips in the existing chip packaging structure, most of the packaging and fixing are done by glue and welding, which is very inconvenient to assemble and disassemble. The glue may age during long-term use, resulting in a decrease in the bonding strength, making the connection between the chip and the packaging structure unstable, which can easily cause damage to the chip. As a result, the existing chip packaging structure uses glue and welding to install the chip and pins, which makes subsequent maintenance and disassembly inconvenient, and the glue is prone to aging, affecting the stability of the packaging structure.
