High-Quality B270 Glass Wafer Optical Substrates For Versatile Applications
B270 is a type of soda-lime glass that is commonly used in the production of glass wafers. It is manufactured by SCHOTT AG, a leading glass manufacturer. B270 glass wafer is known for its high optical quality, flatness, and versatility, making it suitable for a wide range of applications in industries such as electronics, optics, and MEMS (Micro-Electro-Mechanical Systems).
B270 glass wafers are known for their high surface quality and flatness. They are manufactured with precise control over the manufacturing process to ensure a smooth, uniform surface and minimal defects. This enables accurate and reliable processing and integration in various applications, including semiconductor manufacturing, microelectronics, and sensors.
B270 glass wafers are available in a range of thicknesses, typically ranging from a few micrometers to several millimeters. This allows for flexibility in selecting the appropriate wafer thickness for specific applications, accommodating the requirements of different fabrication processes and device designs.
B270 glass wafer exhibits good mechanical strength and chemical resistance. It can withstand mechanical stress and is resistant to common chemicals, making it suitable for use in environments that require durability and chemical stability.

FAQs:
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.
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.
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.
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.
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.
