Ceramic PCB AIO203 Material 3

Aluminum Oxide(AI203) is the most popular ceramic material for the Ceramic PCB, as the high thermal conductivity, low roughness, low expansion. Meanwhile the cost is cheaper than the ALN and BeO. Customer used it in the communication Antenna, Automotive power control modules, AC converters, lighting system, Switch regulators, High-power LEDs, Laser, IC package and etc.
