Abstract :
A kind of new silver paste with silver content about 50wt%, nano-silver paste, significantly different with normal silver paste in roasting temperature, was prepared using nano-silver powder, ethanol, n-butyl alcohol, n-hexyl alcohol and low polymer fibre. The nano-silver paste shows weight loss and volatilization with different levels on thermogravimetric (TG) analyzing curve. Field emission scanning electron microscope (FESEM) analysis indicates when roasting temperature is controlled at 200°C, the surface of finished silver film has already been compact and smooth. And finished silver film has stronger adhesive with ceramic and mental substrates, while the adhesive is poor with slippery glass. The minimal square resistor of obtained silver film can reach 7.8mΩ/□.
