Components Of Conductive Silver Paste

The conductive silver paste is mainly composed of conductive materials, adhesives, solvents and additives.

1), conductive material factory

Conductive materials can be divided into conductors and semiconductors according to their electrical conductivity. Conductive materials can be divided into inorganic and organic systems. Among the inorganic systems, there are metallic materials Ag, Cu, etc .; non-metals include amorphous carbon and tin oxide.

2), adhesives, solvents

Adhesives are the main film-forming substances that make up conductive inks. There are natural resin, synthetic resin, alkali metal silicon salt and so on.

The solvent is used to dissolve the binder resin. Therefore, the solvent must have the ability to dissolve the binder resin. On the other hand, the solvent cannot make the conductivity of the conductive material unstable and reduce the physical and chemical properties of the ink film. The choice of solvent should also consider the effect of solvent evaporation rate on printability.
