The importance of carrier resin in low-temperature conductive silver paste for thin-film switch touch screen keyboards
Low-temperature halogen-free conductive silver paste is a light asset manufacturing industry, primarily depending on carrier resin, silver powder, and formula elements.
Low-temperature halogen-free silver paste is a material for preparing conductive functional components in flexible electronic circuits such as film switches, touch screens, and keyboards. The quality of the carrier resin is a critical factor determining the paste's excellent film-forming properties.
The carrier resin in conductive silver paste must first meet the requirements of thixotropy, conductivity, adhesion, flexibility resistance, printability, resistance to sweat, antioxidant properties, and hardness, all in line with the electronics circuit manufacturing standards.
Next, the leveling, volatility, and rheological behavior of the silver paste carrier resin are crucial for ensuring that the paste transfers from the silk screen mesh to the workpiece surface during the printing process, forming conductive patterns on the film switch touch screen keyboard.
Classic saying in the paste industry: Only superior carrier resins can produce high-performance conductive silver paste.
