The manufacturing of ceramics can adopt a combination of traditional and modern methods. Traditional processes use substrate preparation. Yes, ceramic substrates start with a commonly used material, such as aluminum oxide or aluminum nitride, which are in powder form. Then mix it with glass like material and add it to the liquid for bonding, and the mixture becomes a slurry. Afterwards, we will shape it according to our needs. Then laminate the copper-clad laminate onto the ceramic material. This will be used as our basic ceramic PCB material.
The rest of the ceramic PCB manufacturing is the same as what we follow for ordinary PCB substrates. Use CNC machine to drill holes on the substrate and add photoresist on the PCB. Lithography tools come from plotters and are used for exposure, development, etching, and stripping.
