Turnkey assembly.

The distinction that matters in assembly work is whether anyone tested the thing. A kit of correct parts is not a product, and the discovery that it does not work belongs on our bench, not yours.

• Enclosure — printed or moulded, ours or supplied. See PCB enclosures.
• Wiring harness — made to a schedule, cut, crimped, sleeved and dressed.
• Board mounting — standoffs, insulation, torque where it matters.
• Mechanical integration — brackets, fasteners, seals, moving parts.
• Sealing and filtration — gaskets and vent filters cut in-house to the same drawing set.
• Labelling and serialisation — legends, ratings plates, serial numbers recorded.
• Functional test — every unit powered up and confirmed to do what it should.
• Packing — for the transit the product actually faces.

Assembly problems are rarely assembly problems. They are interface problems, and they surface on the bench because that is the first place two suppliers' work meets.

The housing from supplier A has a cable entry 3 mm from where the harness from supplier B needs it. The gasket is the right outline and the wrong thickness. The board stands 1.5 mm too tall for the lid once the connector is seated. Each of these is somebody else's tolerance, and resolving it means three parties agreeing whose drawing was wrong.

When the enclosure, the printed brackets, the gasket and the vent filter are all cut here to one drawing set, that entire category of problem largely disappears — and where it does appear, there is one team accountable rather than a chain pointing at each other.

As standard, every unit is powered up and functionally confirmed. That is a real check, and for many products it is the right level.

If your product needs more, it has to be specified before the first build rather than requested afterwards — because a test regime is a process, not an inspection:

• Recorded measurements against limits — values captured per unit rather than a pass or fail.
• Burn-in — running for a defined period to catch early-life failures before they reach a customer.
• Serialised test certificates — records tied to serial numbers and supplied with the consignment.
• Custom test fixtures — which we design and print in-house. See jigs and fixtures.

Work done to your brief is your intellectual property, including any CAD we produce, and you receive the files. We are a manufacturer rather than a licensor — holding a customer's design hostage is a poor way to earn a repeat order.

If the design is not finished, we can do that part too: see product design engineering. If it is finished and you need volume, see contract manufacturing.
