CERAMIC PCB
FX PCB can provide the ALN(Aluminum oxide) and AIO203(Aluminum Nitride) Ceramic PCB, we can make ENEPIG, ENIG, Immerison silver surface,you can check the material datesheet and our capability from the below tables.
Ceramic PCB is actually made of electronic ceramic materials and can be made into various shapes.
The ceramic circuit board has the following characteristics: high-temperature resistance, high electrical insulation, low dielectric constant, low dielectric loss, high thermal conductivity, good chemical stability, and the thermal expansion is almost can be coefficients of components.
Description
What are the Ceramic PCB materials Properties?
FX PCB listed two Ceramic PCB material(ALN and AIO203) Properties for your reference:
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 And keep the AI203 materials properties table below:
CERAMIC PCB AIO203 Materials datesheet:
