Electronic packaging materials

Tungsten copper alloys are widely used in electronic packaging, semiconductor manufacturing and microelectronic devices. It can be used to manufacture electronic packaging materials, thermally conductive components and high temperature electrical contacts because of its good thermal conductivity and high temperature stability.

First of all, tungsten copper alloy can be used as electronic packaging materials for packaging electronic components. The functions of the package mainly include mechanical support, heat dissipation channel, power distribution, signal transmission, chip sealing and environmental protection. Tungsten copper alloy has a low expansion coefficient and high thermal conductivity, making it an ideal packaging material.
In addition, the expansion coefficient and thermal conductivity of the tungsten-copper alloy can be adjusted and controlled by the component distribution ratio to meet different packaging requirements.
Second, tungsten-copper alloys are also used to manufacture thermally conductive components. Because the tungsten copper alloy has good thermal conductivity, it can effectively conduct the heat of electronic components, prevent the equipment from overheating, and improve the stability and reliability of the equipment.

In addition, tungsten copper alloys are also used in the manufacture of high temperature electrical contacts. Its characteristics of high temperature resistance and arc ablation resistance make it work stably in high temperature environment and ensure the normal operation of electronic equipment.
The application of tungsten copper alloy in the field of electronic packaging is mainly reflected in the following aspects:
High temperature stability: The high melting point and high density of tungsten ensure that the material can still maintain stable performance in high temperature environment. This is crucial for electronic packaging, as it ensures that the device will work even in extreme conditions.
Signal transmission and heat dissipation: The high electrical conductivity and high thermal conductivity of copper ensure the rapid transmission of signals and the heat dissipation efficiency of the device. This is of great significance for improving the performance and prolonging the service life of electronic equipment.
Dimensional stability: The low expansion coefficient of the tungsten-copper composite material allows it to have a small dimensional change when the temperature changes, which is essential to maintain the stability and reliability of the package structure.
Excellent processing performance: Tungsten copper alloy has excellent processing performance, which can accurately control the shape and size of the material to meet the high-precision requirements of electronic packaging.
Tungsten copper electronic packaging and heat sink materials have both the low expansion characteristics of tungsten and the high thermal conductivity characteristics of copper, and their thermal expansion coefficient and thermal conductivity can be changed by adjusting the composition of tungsten copper, thus providing a wider range of applications for tungsten copper. Tungsten copper material has high heat resistance and good thermal conductivity, and the thermal expansion coefficient of silicon wafer, gallium arsenide and ceramic materials match, so it is widely used in semiconductor materials. Suitable for high-power device packaging materials, heat sink materials, heat dissipation components, ceramics and gallium arsenide base.
