Features of Ag Sintering Paste

High bonding strength by metal sintering with nano Ag and micron Ag powders

・Low electrical resistance
・High thermal conductivity
・Unique resin dispersion system for achieving high heat resistance and reliability with low stress (exhibits high bonding reliability even at 250°C)​

Comparison with Conventional Ag Paste

The bonding process of Ag sintering paste

・Utilization of existing equipment is possible
　Pressure-less bonding
　Same application method as conventional Ag paste
・Apply low temperature 200-250°C for sintering
・Curing in air or nitrogen atmosphere
