Frequently Asked Questions
What is your minimum order quantity?
No MOQ. We build from a single prototype board to full-volume production on the same quality system, so you can validate a design before committing to quantities.
How fast can I get my PCB prototypes?
Standard fast-turn prototypes ship in 5-7 working days for most 2-8 layer builds; HDI and special-material boards typically take 7-12 days. Quotes come back within 24 hours, and expedited options are available – see our PCB lead time page for details.
Which certifications do you hold?
Our quality system is certified to ISO 9001:2015 and IATF 16949, with UL, RoHS, and CQC approvals. Boards are built to IPC-6012 / IPC-A-600 Class 2 as standard, with Class 3 available on request.
Do you check my design files before production?
Yes. Every order includes a free Design for Manufacturability (DFM) review of your Gerber or ODB++ files. Our engineers report risks and fix suggestions within 24 hours, and production starts only after DFM verification.
What files do you need for a quote?
Send Gerber or ODB++ files plus the board outline (DXF preferred), target quantity, and any stack-up, impedance, or surface-finish requirements. For PCBA, include the BOM and pick-and-place files. You will receive a quote within 24 hours.
How do you protect my design files and IP?
We sign an NDA on request before you send any files. Gerber, ODB++, and BOM data are stored on access-controlled servers, used only for your production, and never shared with third parties. Files can be deleted from our system at your request after delivery.
Do you ship internationally?
Yes – we ship worldwide via DHL, FedEx, and UPS, with air and sea freight for volume orders. Express delivery typically takes 2-4 days to North America and Europe, and every shipment is vacuum-packed with moisture protection and full tracking.
