Ultra thick quartz substrate
Your core needs, our solutions
Q: What should be done if traditional materials are prone to deformation or damage in high temperature or corrosive environments?
A: Our ultra thick quartz substrate provides excellent thermal stability and chemical inertness, which can maintain dimensional stability at high temperatures of 1200 ℃ and strong acid and alkali environments, extending the service life of equipment.
Q: Precision instruments require extremely high dimensional accuracy and surface flatness. How can this be achieved?
A: Through advanced grinding and polishing processes, we can provide a surface roughness of Ra ≤ 0.1 μ m, with a thickness tolerance controlled within ± 0.01mm, meeting the precision requirements of semiconductor, optical and other fields.
Q: Can special projects require non-standard sizes and shapes for quick customization?
A: We support full-size customization, with a diameter range from 10mm to 2000mm and a thickness of up to 100mm. We also provide secondary processing services such as drilling, slotting, and irregular cutting.
