Sandblast Laser Scribing Zirconia Alumina Ceramics Substrate High Thermal Conductivity
Ceramic Substrate:
The ceramic substrate, is a sheet-like material which forms a supporting base for the film circuit component and the externally-applied component on the basis of the electronic ceramic.Ceramic substrates have high temperature resistance, high electrical insulation properties, low dielectric constant and dielectric loss, high thermal conductivity, good chemical stability, and similar thermal expansion coefficients of components.According to the application field of ceramic substrate, it is divided into HIC (hybrid integrated circuit) ceramic substrate, focusing potentiometer ceramic substrate, laser heating fixing ceramic substrate, chip resistor substrate, network resistor substrate, etc.; Different ways, ceramic substrates are divided into two types: molded tablets and laser scribe films.Ceramic substrate materials include Al2O3, AlN, SiC, BeO, BN, mullite, and glass ceramics. Although the thermal conductivity of Al2O3 ceramic substrate is not high (20W/m.K), it is the most widely used ceramic substrate because of its relatively simple production process, low cost and low price.
