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 belongs to the dry light industry, primarily depending on carrier resin, silver powder, and formula elements.

Low-temperature halogen-free silver paste is a conductive functional material used in the preparation of flexible electronic circuits such as membrane switches, touchscreens, and keyboards, with the quality of the carrier resin being a crucial factor in determining the paste's excellent film-forming properties.

The carrier resin in conductive silver paste must first meet the requirements for thixotropy, conductivity, adhesion, flexibility, printability, resistance to hand sweat, oxidation resistance, and hardness, all at the same time, as required for electronic circuit manufacturing.

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 membrane switch touch screen keyboard.

Classic quote in the paste industry: Only high-performance carrier resins can produce superior conductive silver paste.
