Abstract:
1. A conductive aluminum past comprising: an organic carrier, being composed of organic solvent, resin, and thixotropic agent; an aluminum powder; a glass frit; and a nano-scale metal, selecting from gold, silver, copper, zinc, lead, or any combination thereof, wherein a weight percentage of the nano-scale metal associated with the conductive aluminum paste is around 0.1 through 10 wt %, wherein a particle size distribution D50 of the nano-scale metal is in the range from 10 nanometers to 300 nanometers, wherein the organic carrier, the aluminum powder, the glass frit, and the nano-scale metal are mixed to form the conductive aluminum paste, and addition of the nano-scale metal is used to reduce a sheet resistance value of the conductive aluminum paste, and to increase adhesion of the conductive aluminum paste.
