Conductor pastes (Ag-based)

This paste has high adhesion and high reliability to alumina and glass substrates, as well as to aluminum nitride substrates, which are difficult to adhere to. Further, to prevent sulfidation and migration, which are the demerits of Ag, Ni/Au plating can be applied.
Screen printing, screen offset printing, and dip coating are also possible.
We can customize the paste and print it on the substrates according to your specifications. Please contact us if you have any other requests.
