Silver Sintering Paste

QLAg1110 are nano-silver pastes designed for pressure sintering processes. It utilizes a self-developed paste formulation with excellent electrical and thermal conductivity and high shear strength. These pastes enable highly reliable sintered connections on gold, silver, and copper substrates, providing a high-reliability packaging solution for high-power devices.

QLAg1110 Silver Sintering PasteAdvantages

The porosity of the sintered structure is as low as 7%~9%.

Applicable to Au, Ag, Cu surfaces. The shear strength can be greater than 60 MPa with Ag surface.

High electrical and thermal conductivity, longer lifespan, and higher reliability.

Supporting low pressure sintering process, the temperature can be as low as 230℃ and the pressure can be as low as 10 MPa.
