AT Cut Single Crystal Quartz Blank 70MHz For Frequency Control
AT SC cut Quartz Crystal Round Blanks IEEE standard Single or Double Rotation for TCXO
Cultured Crystal Quartz blanks are made of right-handed Alpha quartz crystal artificially grown bars. The cultured crystal bars are most used to fabricate piezoelectric components for applications as timing, frequency control and frequency selection.
BonTek has QSC41L EFG from Berlin to do angle control. It can work on IT, SC and FC cuts for angle measurement and sorting. We provide quartz crystal blanks in all standard formats: Round, Square, SMD, strip, plano-plano, contoured, lapped, and polished. The most used are AT-cut and SC-cut plates with very strict angle torlerance. Please check below our detailed capabilities.

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.
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.
