Sintered silver pressureless sintered silver pressured sintered silver

The so-called sintered silver, also known as sintered silver paste, silver solder paste, etc., is a new type of high conductivity silver material that sinters nanoscale silver particles into silver blocks. The sintered silver sintering technology is also known as low-temperature connection technology, and the product has the characteristics of low-temperature sintering, high-temperature service, high thermal conductivity, low resistance, and pollution-free. It is a key thermal and heat dissipation packaging technology in wide bandgap semiconductor modules.

Sintered silver technology and the high temperature sintered silver paste in the market are two concepts. The "sintered silver" here refers to the Silver nanoparticle paste sintered in a low temperature environment. The sintering temperature is generally below 280 degrees. Shanren New Material has developed the sintered silver AS9376 that can be sintered at 150 degrees, which is the first in the world.

The sintered silver materials used for power devices by Shanren New Materials include the following models:

AS9330 semi sintered silver: production models include AS9333; AS9335;

Two 9375 pressureless sintered silver: product models include AS9373; AS9375; AS9376; AS9377;

San 9385 pressure sintered silver: product models include AS9385; AS9386; AS9387;

Four AS9200 pressureless sintered silver adhesive: product models include AS9220; AS9221;

Five pre sintered silver film GVF9500 series: can be made into various sizes of nano sintered silver films according to customer needs;

Six DTS (Die Top System) pre sintered solder pads GVF9800 series: Pre sintered silver solder pads, also known as Die Top System, Shanren New Materials can customize various sizes of pre sintered silver solder pads and pads according to customer needs.

Sintered silver is suitable for industries such as high-power RF devices, wide bandgap semiconductor packaging, LED, IGBT, automotive electronics, power distribution, inverters, trams, UPS, etc; This series of sintered silver products, due to the small size effect of nano metal, the melting point of Silver nanoparticle is much lower than that of bulk silver, so it can be sintered at a relatively low temperature. When Silver nanoparticle is sintered, its surface melts and adjacent particles contact each other to form a sintered neck. Then, as the atoms diffuse, the sintering neck continues to grow, and the final sintered body has a melting point close to that of bulk silver. These characteristics of Silver nanoparticle enable it to meet the stringent requirements of low-temperature sintering and high-temperature service.
