Supplier's Category: All Box Build & System Integration: Full product assembly and final packaging
Box build and system integration assembles finished sub-components — PCBs, enclosures, cabling, mechanical hardware — into a complete, tested, ready-to-ship product. It’s the final assembly stage after individual parts have already been manufactured.
Box build quality depends on process discipline at final assembly, where a single wiring or torque error can fail an otherwise well-manufactured product.
- Ask what functional and electrical safety testing happens at the end of the line, not just visual inspection
- Confirm traceability: can a finished unit be traced back to component lots and the operator who built it
- Check whether they handle packaging and kitting, or only bare assembly

Where box build sits in production
This is the last manufacturing step before a unit ships — every upstream process (PCB assembly, machining, molding, finishing) feeds into it.
Typical inputs
- From PCB Assembly (PCBA): populated, tested boards
- From Sheet Metal Fabrication or Injection Molding: enclosures and housings
- From Cables & Wire Harnesses: pre-built interconnects
