96% Alumina(NA-96)
96% Alumina substrates are standard typical ceramic substrates. The stability of physical and chemical properties under high temperatures allows for high operating temperatures and high environmental temperatures, which are ideal for products that require high reliability.
Features
96% Alumina substrates offer high electrical insulation and combined with the stability of physical and chemical properties under high temperatures, are ideal for applications such as Power devices, Automotive, and heater substrates. Substrates offer excellent flatness with minimum camber and surface unevenness.
