Frequently Asked Questions
What is the minimum order quantity for custom flyback transformer winding?
Our standard MOQ is 500 pieces. For urgent prototypes we can produce as few as 50 units with a fast‑track surcharge.
Can you handle high‑frequency (≥ 1 MHz) winding requirements?
Yes. Our semi‑automated lines support up to 2 MHz with low‑loss Litz wire and precision layer alignment.
What certifications do your windings carry for export to the USA?
All units are FCC‑Part 15 compliant, RoHS‑restricted, and come with a CE Declaration of Conformity. ISO 9001:2015 ensures consistent quality.
How do you support OEM/ODM design collaboration?
Our 10 R&D engineers work directly with your design team via CAD exchange, virtual prototyping, and iterative testing. Design‑for‑manufacturability (DFM) reviews are included.
What are the payment terms for first‑time buyers?
We accept T/T (30 % deposit, 70 % before shipment) or L/C at sight. For qualified partners, Net 30 after inspection is available.
Michael Torres, Sr. Procurement – SolarTech Inc.
“The 48‑hour prototype saved our product launch. Pricing was 27% lower than the Chinese competitor we previously used.”
Sara Liu, Operations Manager – MedPulse Ltd.
“Consistent winding tolerance eliminated re‑work on our MRI power modules. Compliance documents arrived with the shipment, simplifying FDA filing.”
James O’Connor, Technical Director – AudioDynamics
“Xinchangda’s OEM design support let us integrate a custom 3‑layer winding that reduced EMI by 18% without extra shielding.”
