Frequently Asked Questions

There is no MOQ for prototypes — we start from 1 board. Small-batch production starts at 5–10 pieces, and mass production from 100 pieces. For your exact quantity we will confirm MOQ in the quote.

Prototypes: 1–3 working days. Small batch: 3–5 working days. Mass production: 7–15 working days, depending on stack-up and component availability. Component lead for hard-to-find parts may add 2–6 weeks — we confirm stock before you commit.

Yes. Turnkey means we source all components, assemble and test the boards — you send GERBER + BOM + firmware and receive finished, tested PCBA. We also handle box build and conformal coating in-house.

For assembly: BOM (bill of materials) and centroid/position file (XY). If we also manufacture the bare PCB, include the GERBER files and stack-up. A PCBA / placement drawing helps us verify. Missing files? We will tell you exactly what's needed within one business day.

We build to IPC-A-610 and IPC-J-STD-001 standards. Sample badges shown on this site (ISO 9001, RoHS, UL, etc.) are placeholders for layout — please ask us to confirm which certificates are currently on file.

Prototype orders: PayPal or T/T. Production orders: T/T 30% deposit, 70% before shipment, or letter of credit for long-term accounts. Standard INCOTERMS is FOB Shenzhen; EXW, CIF and DAP available on request. [PLACEHOLDER]

Within 24 hours on working days. Quotes include unit price, lead time, MOQ and a DFM review summary of any manufacturing concerns in your files.

Yes. Our sourcing team buys against your BOM from a global supplier network and multi-sources critical parts. For scarce components we check stock and give you a realistic lead time before you place the order.

Yes. We sign NDAs before receiving any files, keep designs in restricted-access systems, and wipe/sanitize data per agreement when a project ends. Tell us your requirement — standard NDA, non-circumvention, or specific data handling.

Every production batch ships with inspection reports (AOI/ICT/FCT), a certificate of conformance and first-pass yield summary. Request specific test data at ordering — we archive MES data for 10 years.

Always. We build and fully test a prototype first, get your approval, then move to volume. Sample lead time is 1–3 working days, and sample cost is credited toward production.

We stand behind every shipment. If a defect is traced to our process, we repair or replace at our cost. Send photos, failure analysis data and batch number — we provide a returned-goods analysis within 5 working days.

Small batches go DHL / FedEx / UPS (3–5 days door-to-door with tracking). Volume orders ship by air or sea freight. We provide export documents, certificate of origin and correct HS codes on every invoice. [PLACEHOLDER]
