On October 8,China's leading manufacturer of tungsten copper, molybdenum copper, pure tungsten, pure molybdenum, and heat sink materials, GDRC releases tungsten copper composite materials for electronic packaging and heat sinks.
Tungsten copper composite material for electronic packaging and heat sink
Tungsten copper two-phase composite material has high thermal conductivity and low thermal expansion coefficient, and is regarded as a good heat sink material in high-power equipment. Many experts and scholars at home and abroad have conducted many discussions on tungsten copper as a heat sink material. Mainly include powder modification, adding active agent to improve the sintered density of tungsten copper, etc. With the development of high-power electronic equipment and the development of large-scale integrated circuits, the corresponding material upgrade requirements are put forward, because the tungsten copper composite material has high heat resistance and outstanding thermal conductivity, and at the same time it has the same characteristics as silicon wafers. , The thermal expansion coefficient matched by ceramic materials has been widely used as inserts, links and heat dissipation components, and has become a new important electronic packaging and heat sink material.
At present, the relative density of tungsten copper materials can be up to 99% or more, and powder materials with higher purity are used. As electronic packaging and heat sink materials, there are higher requirements for the quality and function of tungsten copper materials, not only requiring high purity but also uniform arrangement, low air leakage, good thermal conductivity and low thermal expansion coefficient.
