Different Angle Cuts of Single Crystal Quartz Customized Wafers used in various applications
BonTek Optoelectronics provides high quality Single Crystal Quartz wafers in both SAW grade and optical grade. We can offer various orientation options including X cut , Y cut , Z cut , AT cut, ST cut, etc. or just any cut angle you can imaging for your unique applications at reasonable price.
AT, BT, SC cut orientations are for many frequency control application which will be used for many electronic and space application, such as mobile phone and satellite etc. AT-Cut Quartz is the most common cut, particularly used for electronic instrument that require frequency range of 0.5 - 300MHz. Z cut is for some optical application, such as some windows and lens etc. meanwhile, general speaking, the polishing designations are for reducing the electronic resistance or enlarging the optical transmittance.

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.
