Prototyping, Assembly & Testing
From first prototype to tested small batch under one roof — our hardware lab in Chisinau, Moldova assembles, brings up and functionally tests the boards it builds, and prepares devices for FCC, CE, UL and RoHS certification testing. The fast loop between bench and design is the whole advantage.
The free 30-minute session reviews your design files or prototype and maps the path to a tested batch — including the certification route your markets need. You keep the plan either way.
The gap between design files and devices
Contract manufacturers start at quantities you have not earned
You need twenty units to learn, not twenty thousand to warehouse. Small-batch assembly with real test coverage is exactly the stage most manufacturers price away — and exactly what a lab is for.
The prototype loop takes six weeks per lesson
Design, ship files abroad, wait, receive, discover, repeat. Hardware learning speed is set by loop time — with assembly and test beside the design bench, a revision lesson costs days.
Units arrive assembled and unexplained
Boards come back from an assembler with three of ten dead and no story. Our builds come with bring-up records per unit: what was tested, what was measured, what was reworked and why.
Certification is a cliff at the end of the project
FCC, CE, UL, RoHS — discovered late, they are redesigns; planned early, they are checklists. We run pre-compliance checks at the bench and prepare the documentation as the device matures, so the lab visit confirms instead of surprises.
Small batches exist to teach: every unit tested, every failure explained, every lesson folded into the next revision.
What the lab does
Prototype builds with bring-up
Boards assembled, powered, programmed and exercised — each unit with a record of what was measured and fixed.
You get: working prototypes with a paper trail, not a bag of boards.
Small-batch assembly
Pilot runs and small series with functional test on every unit — the quantities where products learn before scaling.
You get: tens to hundreds of tested units, batch-documented.
Test fixtures and functional testing
Purpose-built fixtures that exercise each board’s real functions — power, radio, sensors, interfaces — so a pass means something.
You get: a repeatable test standard every future batch runs through.
The certification path
Pre-compliance checks at the bench, documentation packages, and preparation of devices for FCC, CE, UL and RoHS testing at accredited labs.
You get: a device that arrives at the certification lab expected to pass.
How it works
Files and feasibility
Your design package reviewed for manufacturability and test access; the batch and certification plan drafted.
First build and bring-up
Prototypes assembled and exercised in the lab, findings fed straight back to design — the fast loop.
Fixture and pilot batch
The functional test fixture built, then a pilot run through it — every unit tested, the batch documented.
Certification and scale-up
Pre-compliance, documentation, accredited-lab testing, and handover to volume manufacturing when the numbers call for it.
A functional fixture exercises what the device actually does. Green lights are earned per unit, and recorded.
Proof, not claims
The lab’s output sits inside shipped products; its discipline shows in the paper trail every batch carries.
Power-station systems experience
Years of work on a novel power station for PV systems — the systems context that keeps assembly and test honest about what devices must survive.
One roof, full loop
Design, prototyping, assembly and testing in one place, wired to our firmware and software teams — the setup page for everything on this bench.
A prototype revision that takes a contract manufacturer weeks turns around in days when design, assembly and test share one room.
Days per lesson, not weeks per shipment.
Put your files on the bench
One 30-minute session with a hardware engineer: your design package or prototype, the honest path to a tested batch, and the certification route for your markets. Fixed-price phases, in writing, before anything starts.

The questions buyers actually ask
What quantities do you assemble?
Prototypes through pilot runs to small series — tens to hundreds of units, each functionally tested. When volumes outgrow the lab, we hand a proven design package and test standard to a volume manufacturer and stay on for quality oversight.
Can you assemble a design we did elsewhere?
Yes — after a manufacturability review of the files, which regularly catches issues cheaper to fix before solder: missing test points, unsourceable parts, footprint mismatches. Findings come in writing either way.
What does "tested" actually mean here?
A purpose-built fixture exercises each unit’s real functions — power rails, radio, sensors, interfaces — against defined pass criteria, and every unit’s results are recorded. A batch from us is data plus devices, not devices alone.
How does FCC/CE/UL/RoHS certification work with you?
We design and prepare for it: pre-compliance checks at the bench, the documentation package, and devices readied for accredited-lab testing. Planned from the start, certification becomes a checklist rather than a cliff — that is the service.
Where is the lab and who runs it?
Our hardware lab in Chisinau, Moldova — run by Fluvius, working daily with our firmware and software teams. One accountable company from schematic to tested batch to the cloud the device talks to.
What does a prototype or batch run cost?
Quoted in writing from your files: component cost, assembly complexity and test depth drive the number. Phases are fixed-price, so the spend is approvable stage by stage.
From schematic to certified device — the one-page version
The Hardware & IoT Lab on one printable page: firmware, electronics, prototyping and certification testing, and how a device project moves through them. Built to be forwarded to whoever holds the budget.
