Ultra thin circular quartz plate/sheet/disc is a precision optical and semiconductor basic component with extremely thin thickness and made by melting high-purity silicon dioxide. With its excellent UV transmittance, extremely low coefficient of thermal expansion, and outstanding chemical stability, this product achieves a perfect balance between high transparency and high temperature resistance in extremely limited spaces. Whether as a window for precision optical instruments, a carrier substrate for semiconductor wafer inspection, or a cover for high-end biomedical microfluidic chips, ultra-thin circular quartz sheets can provide irreplaceable stable performance and are indispensable core high transparency protection and functional components in cutting-edge technology fields.

Frequently Asked Questions (FAQ)

Q: What is the thickness range of "ultra-thin" quartz wafers defined by your factory?

A: Quartz sheets with a thickness of less than 0.5mm are usually referred to as ultra-thin sheets in the industry. The thinnest thickness that can be processed in our factory can reach 0.1mm. For circular quartz pieces with a thickness of 0.1mm-0.5mm, we have mature processing technology that can effectively control warpage and edge breakage.

Q: How do you solve the problem of ultra-thin quartz sheets being prone to breakage during processing and transportation?

A: This is a core process difficulty. We use high-precision CNC double-sided grinding and polishing equipment, combined with a special chemical strengthening cleaning process, to eliminate internal residual stress. On the packaging, customized shock-absorbing vacuum formed trays are used with single piece isolation to ensure zero damage rate in global logistics transportation.

Q: Can we specify special quartz materials (such as JGS1, JGS2)?

A: Absolutely possible. We offer full material customization, including far ultraviolet grade JGS1 (excellent UV transmission, suitable for lithography machines), ultraviolet grade JGS2, and infrared grade JGS3. You only need to provide the application scenario and wavelength requirements, and our engineers will recommend the most suitable material for you.

Q: Can you provide ultra-thin circular quartz plate/sheet/discs with micro holes or special pattern cutting?

A: Okay. In addition to standard circular shapes, we support precision secondary processing such as micro hole drilling, V-groove cutting, chamfering, etc. on ultra-thin quartz plate/sheet/discs, with tolerances controlled within ± 0.01mm.

Core values and demand resolution

Starting from your practical application, the ultra-thin circular quartz plate/sheet/disc truly solves three major pain points for you: firstly, the problem of "limited space", achieving the highest level of transparency and protection with the thinnest volume in miniaturized devices; The second issue is signal attenuation, where ultra-low impurities ensure high transmittance of ultraviolet and deep ultraviolet light, avoiding energy loss in the optical path; The third issue is "environmental interference". The extremely low coefficient of thermal expansion ensures that the optical focal length and sensing accuracy of the equipment do not shift in high temperature or sudden temperature changes.

Product advantages and comprehensive specification customization services

As a source manufacturer, we are well aware that different devices have vastly different requirements for components, so we provide "unlimited" customized services:

Size customization: The diameter can be cut as needed from 2mm to 300mm.

Thickness customization: Ultra thin range of 0.1mm to 0.5mm, with strict thickness tolerance controlled within ± 0.005mm.

Surface treatment: Provide polishing grade (roughness Ra<1nm), frosted grade according to requirements, and can be coated with anti reflective film (AR), reflective film (HR), and anti-static film.

Edge treatment: Precision chamfering (right angle, oblique angle, rounded corner) effectively prevents glass shards from falling off during assembly.

Application scenarios and customer case analysis

Ultra thin circular quartz plate/sheet/discs are widely used in semiconductor lithography, fluorescence microscopy, biosensors, lasers, and aerospace optical systems. The following is an anonymous application case of a real customer:

Customer case: A high-end biomedical equipment manufacturer in Europe

Background pain point: The customer is developing a new generation of portable point of care (POCT) microfluidic chips. The original 0.8mm thick quartz cover resulted in a larger volume of the entire detection box, and due to thickness issues, the excitation light penetration rate of the bottom LED was insufficient, leading to weak fluorescence signals and affecting detection accuracy. They urgently need to find circular quartz plate/sheet/discs with a thickness of 0.15mm and high transmittance.

Our solution:

Material matching: JGS1 far ultraviolet quartz glass is selected to ensure a transmittance greater than 93% in specific fluorescence bands (such as 450nm-680nm).

Ultimate lightweight and stress control: Successfully reduced the thickness to 0.15mm, and ensured overall flatness (TTV<3 μ m) at a thickness of 0.15mm through improved polishing process, perfectly fitting microfluidic chip channels.

Precision chamfering: A 0.05mm precision chamfering treatment was applied to the edge with a diameter of 12mm, solving the problem of edge scratching rubber seals during automated bonding and assembly for customers.

Final result: The overall thickness of the customer's new generation equipment has been reduced by 40%, the fluorescence signal capture intensity has been increased by about 15%, and the product has successfully passed CE certification and been put into mass production.
