Electronic Systems & Lighting

Ceramic electronic substrates and components provide high-reliability performance for aerospace and aviation applications across a range of temperature, fluids, and environmental conditions. Engineered technical ceramics excel in high-temperature, vibration, and extreme mechanical conditions where lesser materials fail. 

Aerospace-Grade Electronic Substrates
Alumina nitride substrates for aerospace electronic applications. Alumina thick- and thin-film substrates are used to produce durable hybrid circuits for airborne and spaceborne electronic systems. In hot zones with rapid thermal gradients, aluminum nitride (AlN) substrates deliver superior performance — dissipating heat with thermal conductivity 4-6 times that of alumina.
