Silver conductive paste

Nano conductive silver paste

Nano conductive silver paste is a conductive paste developed for precision printing electronic manufacturing needs, composed of nano silver powder, organic carriers, and dispersing agents. The product is coated on the surface of flexible substrates or silicon wafers through screen printing or inkjet printing, and then sintered at low temperature to form a dense silver conductive pattern, which is used for conductive interconnection of components such as flexible circuits, wearable sensors, RFID antennas, and photovoltaic electrodes.

In principle, nano silver particles have extremely high surface energy due to size effects, and can achieve metallurgical bonding between particles through surface diffusion at temperatures far below the melting point of bulk silver, forming a continuous and dense conductive network. Organic carriers endow the slurry with suitable rheological properties during the printing stage, ensuring high-precision forming of micro lines and complete decomposition and discharge during the initial sintering stage. This low-temperature densification feature effectively avoids thermal damage to flexible substrates such as PET at high temperatures, while the silver layer obtains excellent conductivity and adhesion.

The core advantage of this product lies in the low-temperature sintering and high-resolution printing of nano silver powder, which balances ultra-high conductivity and process compatibility; The ultra-thin circuit capability adapts to the trend of miniaturization and integration of wearable devices and flexible electronic products; Excellent conductivity stability, providing reliable interconnect solutions for high-precision electronic manufacturing.
