Super-fine Silver technology has been around for a long time. Due to its excellent antibacterial and antibacterial effect, nano silver is now widely used in various medical, packaging, electronics and other industries. For example, some scalpels are covered with a layer of nano-silver with a thickness of 6 atoms arranged together. Nano-silver has a good effect on killing common E. coli and gonococci.

One of the main characteristics of nano silver is low temperature sintering and high temperature service. The sintering temperature can be as low as 150 ℃, even room temperature, and the melting temperature can theoretically reach 960 ℃. This feature has obvious advantages for the integration of complex microsystem products, especially in multi-level assembly, no longer affected by temperature gradients.
