Resources

USB PCBA resource center for faster RFQ and engineering review.

Use these resources to prepare USB hub, docking, converter and audio PCBA files before sending an inquiry.

RFQ File Checklist

The more complete your files are, the faster engineering review and quotation can move.

  • Gerber or PCB source file
  • BOM with part numbers
  • Schematic PDF
  • Port definition and test requirements
  • Target quantity and delivery date

USB Design Notes

USB 3.x products need extra attention beyond ordinary PCB assembly.

  • Differential pair routing
  • Controlled impedance stack-up
  • ESD protection placement
  • Connector durability
  • EMI layout awareness

Testing Guide

Testing should match the actual product interface and customer use case.

  • USB enumeration
  • Data transfer
  • HDMI or Ethernet function
  • Audio I/O check
  • Aging test and packing inspection

Shared project support

Common USB PCBA project support for every RFQ.

Whether your project is a USB hub, docking station, converter or audio board, Weiai uses the same engineering review workflow to reduce unclear requirements before production.

File reviewGerber, BOM, schematic, PCB source file, sample photos and function notes checked by engineering.
Manufacturing planPCB stack-up, SMT/DIP process, connector assembly, programming method and fixture needs are planned early.
Testing planUSB enumeration, port-by-port transfer, voltage/current behavior, aging and packing checks can be defined by project.
