60Si/40Al Is Also Called Si-40%Al For Packaging Electronic Circuitry

- Jul 26, 2018-

With the rapid development of modern electronic information technology,the electronic equipment was swung in the direction from large-scale integration,miniaturization,cost-effective and high reliability.Microelectronic packaging or housing was in combination with electronic design and manufacture, had an effect on promoting the development of information society.In the light of the growing complexity and intensity in electronic devices and installations,thereby referred to an urgent requires to the development and research of high performance electronics material.Tianjin Baienwei New Material Technology Co.,Ltd has developed a new family of high silicon Si-Al alloys for electronic application.They are produced using the rapid solidification process, which achieves homogeneous and isotropic properties.Their advantageous physical characteristics, combining low thermal expansion, high thermal conductivity and low density make these alloys particularly attractive for packaging electronics.These alloys are easy to machine to tight tolerances using standard machine tools and they can be easily electroplated with gold,silver or nickel finishes.Now, Si-40%Al alloy differential round ingot of size samples are available for your choose.Our company is one of the competitive Al-60%Si alloy manufacturers and suppliers. Welcome to import customized products in stock from our factory.
