As a key packaging equipment, nanosilver sintering machine plays an important role in modern semiconductor manufacturing. Its working principle and application field not only demonstrate the precision and complexity of high technology, but also reflect its unique advantages in the field of power device packaging. This article will introduce in detail the working principle, technical characteristics and application of nanosilver sintering machine in various industries.

Working Principle and Technical Characteristics

The nanosilver sintering machine realizes reliable sintering of nanosilver materials at low temperature through advanced pressure control technology and temperature management. The equipment can control the temperature uniformly and stably during the sintering process, and has a flexible atmosphere control function. The biggest highlight of the nanosilver sintering machine is that it can provide precise and stable pressure (maximum pressure can reach 20MPa), which helps to solve the problems of chip fragmentation and ceramic substrate warping that may occur during the sintering process, thereby ensuring the stability and high quality level of the silver sintering process.

Specifically, the nanosilver sintering machine realizes the sintering of nanosilver paste at a lower temperature by pressurization or non-pressurization, and finally forms a silver interconnection layer. This interconnection layer has excellent thermal and electrical conductivity and high-temperature reliability, and can meet the requirements of low-temperature connection and high-temperature service of third-generation semiconductor power module packaging interconnection.

Field of Application

Nanosilver sintering machine is especially widely used in the field of semiconductor packaging. With the increase in power density and miniaturization of devices, timely heat dissipation has become the key to ensuring the performance and reliability of power devices. As an efficient and reliable packaging interconnection technology, nanosilver sintering technology has become a research hotspot for power module packaging interconnection materials.

Nanosilver sintering machines play an important role in the packaging of wide bandgap semiconductor materials such as silicon carbide (SiC) and gallium nitride (GaN). These materials have the characteristics of high breakdown electric field, high saturation electron velocity and high thermal conductivity, which are very suitable for high frequency, high voltage and high temperature power modules. Nanosilver sintering machines ensure the bonding quality and reliability of these high-performance materials during the packaging process by providing a stable and reliable sintering process.

In addition, nanosilver sintering machines have been widely used in other fields. For example, in the precision press assembly of electronic products, nanosilver sintering machines can provide high-precision pressure control to ensure the precise assembly of various components. In the fields of LED packaging and solar panel manufacturing, nanosilver sintering machines have also played an important role in improving the reliability and service life of products.

Engineering Optimization and Innovation

To improve the bond strength and high-temperature reliability of nanosilver sintered joints, researchers have made many technical optimizations and innovations in recent years. For example, the thermal and electrical conductivity of sintered joints can be improved by adding appropriate particles (such as SiC particles, Ag-coated Ni or Mo particles). The addition of these particles can not only improve the thermal conductivity of the sintered joint, but also reduce the thermal expansion coefficient and Young’s modulus of the brazing layer, thereby improving the mechanical properties and high-temperature stability of the sintered joint.

In addition, researchers have also improved the performance of the interconnection layer after sintering by optimizing the size and shape of the silver particles. Sintering of nano-sized silver particles can achieve large-area bonding at lower temperatures, and spherical silver particles have better sintering quality and reliability than flaky silver particles.

Conclusion

As an important equipment in the field of semiconductor packaging, nanosilver sintering machines play an important role in power device packaging with their unique working principles and technical characteristics. By providing a stable and reliable sintering process, the nanosilver sintering machine ensures the bonding quality and reliability of high-performance materials during the packaging process. With the continuous development and innovation of technology, the nano-silver sintering machine will be used in a wider range of fields and make greater contributions to the development of the semiconductor industry.
