USB PCBA RFQ checklist for faster engineering review and quotation.

A clear RFQ helps engineers quote faster and avoid wrong assumptions. Use this checklist before sending USB hub, docking, converter, audio or industrial interface PCBA files.

Resource CenterProduct CategoriesTesting & QualitySend RFQ

1. Basic project information

  • Product application and market use
  • Target quantity for prototype and batch production
  • Expected delivery schedule
  • Whether NDA is required before file review

2. Engineering files

  • Gerber or PCB source file
  • BOM with manufacturer part numbers when available
  • Schematic PDF for function review
  • Assembly drawing, polarity notes and connector definition

3. USB function details

  • USB version and port count
  • Upstream and downstream connector type
  • Bus-powered or self-powered design
  • Voltage input, current budget and protection requirement

4. Testing requirements

  • USB enumeration and port detection
  • Data transfer or speed requirement
  • HDMI, Ethernet, audio or charging function checks
  • Aging test, fixture requirement and packing inspection

Practical FAQ

Questions buyers ask during USB PCBA preparation.

Can I request a quote without complete files?

Yes. You can send sample photos, port definition and rough requirements for early review, then provide Gerber and BOM for final quotation.

Why is the BOM important?

The BOM helps check component availability, alternatives, cost risk and assembly process before production.

Should I send test requirements with the RFQ?

Yes. Test requirements help define fixture needs, production time and quality control method.

Next step

Turn the checklist into a clear RFQ package.

When your files are ready, send Gerber, BOM, schematic, sample photos, quantity and function notes. If some files are missing, Weiai can still provide early engineering feedback.
