Ag paste for low temperature firing onto glass substrate
This silver paste forms dense membrane, shows low resistivity
and obtains good adhesion to glass substrate by firing at
from 430℃ to 550℃.
Silver paste for ceramic normally starts sintering around 500℃ and even LTCC needs its top temperature between 800℃ to 900℃ for sintering. But the silver paste for low temperature firing is designed to start sintering nearly 350℃ and culminate around 400℃. Besides the paste shows good adhesiveness to glass substrates by sintering around 430℃.
Characteristics comparison of silver paste for low temperature
firing and silver paste for ceramics
- It contains glass frit which is lead free.
- It can be fired at low temperature, 480 degree Celsius.
- It has low resistance value, 3.0μ Ω・cm.
- It has good bonding strength to glass substrate.
