Q: What design file formats do you accept?
A: For PCBA: Gerber files (RS-274X format), BOM, pick-and-place file. For wire harnesses: drawings (PDF, DWG) or physical samples. Our engineers can help organize incomplete files.

Q: What is the minimum order quantity (MOQ)?
A: Sample orders: a few to dozens of pieces. Small-batch orders: from 100 pieces. High-volume production: 1,000+ pieces per run for economical pricing. Lower MOQ for wire harness products – please inquire.

Q: Do you provide component sourcing services?
A: Yes. We can source complete components per your BOM – brand selection, genuine purchasing, incoming inspection. Customers may also supply their own components – we assist with verification and assembly.

Q: What is the prototyping lead time?
A: PCBA prototyping: typically 5-10 business days. Wire harness prototyping: typically 3-7 business days. Depends on product complexity and component availability. Rush orders negotiable.

Q: How do you ensure PCBA testing?
A: We develop custom test solutions per customer requirements. Standard testing includes AOI, ICT, and FCT. For specific products, we can add aging testing, thermal testing, etc. Test reports provided with each shipment.

Q: Do you offer conformal coating services?
A: Yes. We provide PCBA conformal coating – moisture-proof, mold-proof, anti-salt spray. Different protection levels available based on product operating environment.

Q: Do you support custom connector models for wire harnesses?
A: Yes. We have molds for various brand connectors (JST, Molex, TE, Hirose) and standard terminal types. For special connectors, customer can supply or we assist with sourcing.

Q: Do you accept OEM brand customization?
A: Yes. Logo printing on PCBA, customer labels, custom heat shrink tubing logos, labels, tie color options. Packaging also customizable to your brand image.
