One Workflow. One Owner.

PCB fabrication, sourcing, assembly, test, and delivery stay connected under one accountable team.

If your files are ready Send Gerber, BOM, centroid, drawings, and quantity.
If your design is still moving Start with DFM, enclosure, test, or BOM questions.
If sourcing risk is high We flag alternates, lifecycle issues, and channel risk early.
If release records matter Plan FA checks, AOI/X-ray/FCT evidence, labels, and packing.
