| titleOfInvention | Pressureless sintering conductive silver paste and preparation method thereof |
| abstract | The invention discloses pressureless sintering conductive silver paste and a preparation method thereof, and belongs to the technical field of metal materials. The pressureless sintering conductive silver paste comprises the following components in percentage by mass: 30 to 65 percent of nano silver powder, 2 to 5 percent of carrier, 30 to 65 percent of solvent and 0.2 to 2 percent of dispersant; the nano silver powder is obtained by only performing centrifugal sedimentation and not performing high-temperature drying, and the water content of the nano silver powder is 0-20%; the particle size range D50 of the nano silver powder is 5-80 nanometers, the nano silver powder used in the invention is not dried at high temperature, the agglomeration of the nano powder is less, the sintering temperature can be low, the packaging and interconnection of the silver powder and the base material can be better realized, and the reliability of the device is improved; in the implementation process, the slurry components are added with the following components in a mass ratio of 1: 2-4 of cyclodextrin and triammonium citrate are taken as stabilizing agents, so that the shearing force of the sintered slurry is obviously improved. |
