Even the cost for ALN will be more expensive than the AIO203, ALN has the high conductivity and the expansion coefficient matching Si, which makes the customers still choose it as the material for their products, Here you can see the details for the ALN material and the Ceramic capability for FX PCB.
FX PCB use the ceramic material imported from Germany and Fujian Huaqing, all incoming material will be strictly checked for the material properties. See the capability of FX PCB for the Ceramic.
