Al2O3 Ceramic Substrate for Thin/Thick Film Electronic Circuit
This ceramic material is characterized by its extremely high strength and thermal conductivity. The outstanding surface quality on both sides makes it the perfect companion for any commercial thick film paste and even makes it suitable for a number of thin film applications (sputtering). A960 Alumina offers consistently reliable and convincing performance even when subject to high thermal and electrical loads in terms of its: Thermocycling capability, Thermal shock resistance, Flexural strength, Surface quality, Thermal conductivity. This makes A960 Alumina Ceramic Substrates ideal for power electronics in conjunction with direct copper bonding (DCB) and active metal brazing (AMB).
