Borofloat 33 Glass Substrate Engineered for Excellence in High-Tech Applications and Precision Operations

‌Borofloat 33® Glass Substrates: Precision, Durability, and Versatility Redefined‌

Unlock next-level performance for your high-tech applications with ‌Borofloat 33® Glass Substrates‌, the borosilicate glass engineered for extreme thermal, chemical, and mechanical resilience. Renowned for its ultra-low thermal expansion and superior surface quality, Borofloat 33® is the go-to choice for industries demanding precision under stress.

‌Why Borofloat 33® Stands Out‌

• ‌Exceptional Thermal Stability‌: Withstand rapid temperature swings (-60°C to 450°C) without distortion, thanks to its near-zero thermal expansion (CTE: 3.25 × 10⁻⁶/K).
• ‌Optical Clarity & Chemical Resistance‌: High transmission from UV to IR (280nm–2,000nm), paired with resistance to acids, alkalis, and solvents, ensures longevity in harsh environments.
• ‌Flame-Polished Surface Perfection‌: Achieve minimal surface roughness (≤1nm Ra) and pristine flatness, critical for MEMS, microfluidics, and thin-film coatings.
• ‌Customizable Solutions‌: Available in thicknesses (0.3mm to 15mm), sizes up to 1,100mm × 1,450mm, and post-processing options (chemically strengthened, etched, or drilled).

‌Applications That Demand Excellence‌
From semiconductor wafer carriers and precision optics to lab-on-a-chip devices and high-power LED encapsulation, Borofloat 33® empowers innovation across:

• ‌Electronics‌: RF/microwave substrates, hermetic packaging
• ‌Biotech‌: Microfluidic chips, biosensor platforms
• ‌Energy‌: Solar panel covers, fuel cell components
• ‌Industrial‌: High-temperature viewports, laser system optics

FAQs:

1. Q: What are the products you mainly work on?

A: We look at ourselves as the piezo wafer specialist. We are the very first to work with Single Crystal Quartz in China about 30 years ago. Then gradually we step in the field of LiNbO3, LiTaO3, Quartz glass, LGS, CTGS etc. Especially, if you are looking for a piezo quartz supplier, we are the ultimate choice! We export millions of quartz blanks each year because we master the AT, SC and IT cuts with superior angle precision.

2. Q: Can you accept product customization?

A: Yes, of course. We can fabricate as per your request. In addition, we are so experienced with piezo wafers that we can provide you relevant suggestions if you are not 100% sure about your choice. Besides, we do have some standard wafers in stock, please check with us.

3. Q: Can you deliver the goods via our courier agent?

A: Yes, we would suggest you go with the courier agent you are most familiar with (DHL, FedEX, UPS etc.). We can ship via your account. And, of course, we will pack the products safely in acceptable size to help you save the shipping cost. If you need us to take care of the freight, it’s also not a problem. We also have good discount with the international courier companies.

4. Q: How can you guarantee we get what we want safely?

A: The wafer products are fragile and sometimes expensive. The last thing, as the manufacturer, we want to see is the products we make were damaged during courier. As a result, we will pack the wafers adequately and put them in a proper carton filled with buffer sponge. However, accidents are inevitable sometimes. So, please follow the “Acceptance check” steps shown in the drawings below. If the unwanted happened, we will either give the replenishment or refund if you follow the checking steps.

5. Q: Can we visit your factory?

A: Sure. Factory inspection is important for large quantity purchase and long-term cooperation. Face to face discussion is what we mostly confident with. During the past years, big names around the world have witnessed our progress in factory build-up. These days, due to the Covid-19 pandemic, we also had the experience of videoconferencing with global buyers.

Acceptance Check

• The product is fragile. We have adequately packed it and labeled it fragile. We deliver through excellent domestic and international express companies to ensure transportation quality.

• After receiving the goods, please handle with care and check whether the outer carton is in good condition. Carefully open the outer carton and check whether the packing boxes are in alignment. Take a picture before you take them out.

• Please open the vacuum package in a clean room when the products are to be applied.

• If the products are found damaged during courier, please take a picture or record a video immediately. DO NOT take the damaged products out of the packaging box! Contact us immediately and we will solve the problem well.

Founded in 1999, Hangzhou Freqcontrol Electronic Technology Ltd. is a China leading manufacturer of piezoelectric crystal wafers, substrates, components and single crystal growth. We, known as the "CQT Group" in global market, headquartered in Hangzhou, China, empowered by its manufacturing sites in Shanghai, Jiaxing and Deqin etc.

Our products are mainly used in RF Telecom, Semiconductor, Biotech, Optical engineering and frequency control industries. The monthly production capacity: 500K single quartz blanks (SC, AT, IT, FC, etc.), 20K quartz wafers (AT, ST, X, Z, etc.), 10K LiNbO3 wafers (3~8 inch), 10K glass wafers (Fused silica, Borofloat33, Corning, etc.), 8K LiTaO3 wafers (3~6 inch), and 100K filters/oscillators (VCXO, TCXO).

Our company vision is to be a reliable primary Microelectronic substrates supplier in today's world.

The CQT Group consists of five major plants with total floor area over 10,000 m². Our production machines include crystal growth furnace, wire saw, X-ray orientation, grinding machine, polishing machine, chamfering machine, CNC, REDOX chambers etc. Inspection equipment include Flatmaster 200, AOI, profilometer, optical imager, X-ray inspector etc. We are also equipped with Class 100 and 1000 clean rooms.

The CQT group is primarily known as the expert of hexagonal crystals, We master the manufacturing process of single & doubly rotated quartz blanks, and we can provide quartz of any orientation cut whether given by IRE , Miller index, Euler angle or conventional sign.
