High-precision quartz drilling plates: A guide to the application of core special components in the field of precision manufacturing
Quartz drilling plates are core functional components made from high-purity quartz materials through precise processing. The purity of SiO₂ can reach up to 99.99%. Different from ordinary flat quartz plates, it retains the basic advantages of quartz substrate such as high-temperature resistance, high light transmittance, and chemical stability. At the same time, through ultra-fast laser and CNC precision drilling processes, it can achieve precise forming of hole diameters ranging from 0.1mm to 50mm. They are indispensable key supporting components in demanding conditions such as semiconductors, high-end optics, and medical equipment.
As a core advantageous product in the field of precision processing, quartz drilling plates exhibit particularly outstanding thermal performance. Their long-term tolerance temperature can reach 1250℃, and the short-term peak tolerance temperature can exceed 1400℃. The thermal expansion coefficient is as low as 5×10⁻⁷/℃, allowing them to withstand intense alternating cold and hot impacts without deforming or cracking, and fully meeting the long-term stable operation requirements of extreme conditions such as semiconductor vacuum chambers and high-temperature optical processing.
In the optical performance aspect, the overall light transmittance of the high-end quartz perforated sheet remains above 99% across the entire spectrum, covering the range from deep ultraviolet to near-infrared. After the surface of the holes is polished by plasma in a dust-free environment, the roughness (Ra) is less than or equal to 0.2 μm. For medical-specific models, the roughness can be reduced to less than or equal to 0.1 μm. This significantly reduces light transmission loss and avoids interference caused by the cracking at the hole edges and burrs, making it an ideal substrate for laser reference sheets, endoscope light guiding components, and optical light transmission components for lithography.
In terms of processing accuracy and scene adaptation, the leading suppliers in the current industry can stably control the aperture tolerance within ±0.01mm. Through a comprehensive precision inspection system, they conduct a full inspection of 12 indicators such as aperture tolerance, light transmittance, and thermal expansion coefficient for each batch of products, and provide a complete inspection report upon delivery. Besides the conventional semiconductor and optical scenarios, the medical-grade quartz perforating sheets that have passed ISO 10993 biocompatibility certification can withstand repeated sterilization at 134℃ high temperature and high pressure, fully meeting the clean usage requirements of medical endoscopes.
At present, the quartz drilling plate industry in China has formed a high-end industrial cluster centered in Dinghai County, Jiangsu Province. The original manufacturing entities, relying on fully autonomous heat processing, cold processing, and laser dust-free precision processing lines, can undertake all kinds of customized demands ranging from standard ready-made products to non-standard special-shaped holes and arrayed multi-pores. Regular samples can be delivered within 7-12 days. The products have been widely used in eight fields such as semiconductor equipment manufacturing, precision optical instruments, medical endoscopes, and university research, and have been exported to more than ten countries in Europe and Southeast Asia, providing stable core component support for the improvement of process yield in the high-end manufacturing field.
