Box Build
From tested board to finished product.
Turnkey system assembly: your PCBAs integrated with enclosures, cabling, and firmware — functionally tested, serialised, and packed so the next person to open the box is your customer.
The last mile of manufacturing
A working PCBA is not a product. Between the tested board and the unit your customer unboxes sits a chain of unglamorous, precision work: enclosures, harnesses, gaskets, torque values, firmware versions, labels, and the final test that proves the whole thing behaves as one device.
Box build puts that chain inside the same four walls that made your boards. One partner, one quality system, one accountable schedule — instead of a relay race between a board house, a cable shop, and whoever screws it all together.
How a box build runs
01
Integration planning
We turn your build documents into a station-by-station work instruction — BOM levels, torque specs, routing diagrams, test points.
02
Sub-assembly
PCBAs, harnesses, and mechanical sub-assemblies are built and tested individually before they meet the enclosure.
03
System assembly
Boards, wiring, displays, and mechanics come together in a controlled sequence with in-process checks.
04
Firmware & configuration
Units are flashed, configured, and serialised — every device leaves with a known identity and software state.
05
Final test & pack-out
Functional testing to your pass criteria, then labelling and packaging ready for your warehouse or your customer's desk.
| Scope | PCBA + enclosure + harness + firmware + final test + pack-out |
|---|---|
| Enclosures | Plastic, sheet metal, extruded — customer-supplied or sourced |
| Cabling | Harness assembly, crimping, routing, dressing |
| Firmware | Programming & configuration during assembly |
| Testing | Functional test to your procedure; burn-in on request |
| Pack-out | Serialisation, labelling, retail or bulk packaging |
Frequently asked questions
What exactly does box build include?
Everything after the bare PCBA: mounting boards into enclosures, wiring harness assembly and routing, displays and connectors, firmware programming, final functional testing, serialisation, labelling, and packaging. You define where it stops — some customers take tested sub-assemblies, others take retail-boxed product.
Can you source enclosures and mechanical parts too?
Yes. Enclosures, fasteners, cables, and mechanical parts can be customer-supplied or sourced by us through the same vetted-channel process we use for electronic components.
How do you test assembled units?
Against your functional test procedure — power-on tests, I/O checks, communication tests, calibration steps. If you don't have a formal procedure yet, we help define one during integration planning. Burn-in is available where reliability requirements call for it.
What documents do you need to quote a box build?
A full BOM (electronic and mechanical), assembly drawings or an exploded view, wiring diagrams for any harnesses, firmware and programming instructions, and your test criteria. A sample unit — even a prototype — makes quoting faster and more accurate.
