Its main components are aluminum powder and silver powder, along with additives and dispersants, and are prepared through a series of production processes. Mixing is the first step in aluminum-silver paste production, aiming to evenly blend the aluminum powder, silver powder, dispersant, and additives to form a homogeneous paste. The various raw materials are added to a container according to the formulated ratio and mixed using a stirrer to ensure thorough mixing.

[0003] In the prior art, when aluminum powder, silver powder, dispersant, additives, etc. are uniformly mixed, stirring is performed by existing stirring blades.
