Frequently Asked Questions
What are the products you mainly work on?
We are piezoelectric wafer specialists with 30 years of experience. We were the first to work with single crystal quartz in China and have expanded to LiNbO3, LiTaO3, quartz glass, LGS, and CTGS. We export millions of quartz blanks annually with superior angle precision for AT, SC, and IT cuts.
Can you accept product customization?
Yes, we can fabricate according to your specifications. Our experienced team can provide technical recommendations if needed. We also maintain standard wafer inventory for immediate delivery.
Can you deliver the goods via our courier agent?
We can ship using your preferred courier (DHL, FedEx, UPS) with your account. We optimize packaging to reduce shipping costs and can also arrange freight if required.
How can you guarantee we get what we want safely?
We use adequate protective packaging with buffer sponge in proper cartons. Please follow our acceptance check procedure: inspect outer carton condition, photograph packaging before opening, open vacuum packages in clean rooms only, and immediately document any damage without removing products from packaging.
Can we visit your factory?
Factory inspections are welcome for large quantity purchases and long-term partnerships. We also offer video conferencing for remote discussions.
Acceptance Check Procedure
