Frequently Asked Questions
Double-side polishing improves flatness and surface uniformity, which is critical for thin-film deposition, metallization, and reliable circuit printing in power electronic applications.
The substrate can achieve a high-precision polished surface with controlled roughness suitable for thick-film and thin-film circuit processes.
Poor flatness can lead to uneven metallization, weak adhesion, and reliability issues in power electronic circuits, especially under thermal cycling conditions.
Yes, after proper polishing and cleaning, alumina substrates are suitable for thick-film or thin-film printing processes used in ceramic PCBs.
Alumina offers lower cost and excellent insulation, while aluminum nitride provides significantly higher thermal conductivity for high-power heat dissipation applications.
Warping is usually caused by uneven thickness, improper firing conditions, or thermal stress during processing and high-temperature cycling.
Alumina remains widely used due to its stability, mature processing technology, cost advantage, and reliable electrical insulation performance.
Yes, alumina substrates can be supplied with controlled surface finish and dimensions suitable for metallization or hybrid circuit structures.
