Frequently Asked Questions
What are the products you mainly work on?
We specialize in piezoelectric wafers, being China's first single crystal quartz manufacturer with 30 years of experience. Our expertise extends to LiNbO3, LiTaO3, quartz glass, LGS, and CTGS materials. We are the preferred supplier for piezo quartz, exporting millions of quartz blanks annually with superior angle precision in AT, SC, and IT cuts.
Can you accept product customization?
Yes, we offer complete customization capabilities. Our experienced team can fabricate to your exact specifications and provide technical guidance if needed. We also maintain standard wafer inventory for immediate availability.
Can you deliver the goods via our courier agent?
We can ship using your preferred courier service (DHL, FedEx, UPS, etc.) via your account. Our optimized packaging minimizes shipping dimensions to reduce costs. We also offer freight management with discounted international carrier rates.
How can you guarantee we get what we want safely?
We employ robust packaging with buffer sponge and proper cartoning to protect fragile wafers during transit. In case of damage, we provide replacement or refund when you follow our acceptance check procedure.
Acceptance Check Procedure
- Handle products with care upon receipt and inspect outer carton condition
- Carefully open outer carton and check packaging box alignment - photograph before removal
- Open vacuum packaging in clean room environment when ready for application
- If damage is detected during courier, photograph/video immediately without removing from packaging. Contact us for resolution.
