8. Frequently Asked Questions

Q1: What exactly is included in Full BOM Procurement?
A: We manage the entire process: component selection advice, supplier qualification, purchasing, inspection, and inventory management. You simply provide the BOM.

Q2: How do you ensure components are genuine?
A: We source exclusively from authorized distributors and franchised partners, provide original certificates, and maintain full lot traceability. Our in-house lab performs incoming inspection.

Q3: What design files do you need?
A: We require Gerber files, BOM, centroid file, and schematics. Our engineering team will perform a complimentary DFM analysis and provide feedback.

Q4: Is there a minimum order quantity (MOQ)?
A: No MOQ for prototyping. Single-board orders are accepted.
