Description
Al2O3 Alumina Ceramic Substrates:
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).
AlN Aluminum Nitride Ceramic Substrates:
Achieving maximum performance in the smallest possible space inevitably causes electronic components to develop increasingly high temperatures. This heat must be dissipated quickly and reliably in order to protect the valuable components. This is where UNIPRETEC's AlN(Aluminum Nitride Ceramics) sets the benchmark. With outstanding insulating properties and extremely high thermal conductivity (≥ 170 W/mK), Aluminum Nitride is perfect for the extremely high performance required in the electronics industry. AlN ceramic enables the compact, affordable construction of components and hybrid designs with high integration density. Extraordinary mechanical strength and a low thermal expansion coefficient enable seamless system integration.
