Product description
Product Description:
High Thermal Conductivity Alumina Ceramic Plate / Substrate
This Alumina ceramic Substrates 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).
With Its extremely fine surface quality, Alumina Ceramic Substrates is designed especially to meet the highest demands in thin-film technology.
Alumina Ceramic Substrates 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
We can make any thickness as you need from 0.25 to 1.2mm. Max length we can provide is 280mm.
