Aluminum nitride (AlN) metallized substrates

Outline

AlN metallized substrates are made by plating nickel or gold AlN substrates after they have been burned at high temperature with special tungsten paste on their surface. They are highly reliable because of the strong joint of the circuit material and the AlN substrates, which was made by the co-fire process. AlN metallized substrates are also suitable for making multi-layered substrates that have through holes.
