Detailed Product Description

BonTek 6 Inch Polished Single Crystal Quartz Wafers

Quartz blanks are thin plates, with diameter from 4.0 up to 20 mm or even more, made from quartz crystal. Blank surface can be fine lapped, chemically etched or polished. The cut angles mostly used are: family of AT-cuts, BT-cut, CT-cut, DT-cut, X-cut and Y-cut. They are used for production of quartz crystal units, quartz crystal filters, piezoelectric transducers and for other applications.
They can be delivered as unplated or plated with metal electrodes. The thickness of blanks can be from 0.040 up to 1.0 mm or more. For AT, BT, X and Y cuts the thickness can be specified by resonant frequency and tolerance. The blanks shape can be plan-parallel (unbevelled or bevelled ), plan-convex or bi-convex with customer specified radius of convex-surface.

FAQs:

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.

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.

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.

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.

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.
