8 disciplines
in one team — from schematic to packaging
Services
Everything turnkey — or just the stage you are missing
Come with an idea, a spec or ready Gerber files — we pick up the project at any stage.
Electronics design
From the spec to the schematic: component selection, circuit design, prototype.
PCB layout
1–8 layer layout designed for assembly — ready for production from day one.
Firmware
Embedded software for microcontrollers, in-line flashing, adaptation to your tasks.
SMD and THT assembly
Automated SMD placement down to 0402, hand soldering of connectors and power parts.
Testing and inspection
Optical inspection, functional test to your test plan, a report for every batch.
3D modelling
Enclosures, mounts and parts for your board — the model is matched to the PCB layout.
3D printing
Prototypes and small series of enclosures: PLA, PETG, ABS, nylon.
Packaging design and packing
Packaging designed for your product, labelling and packing — for series and small batches.

Why ALEXO
What changes when one team runs your project
| Topic | ALEXO | Typical scenario |
|---|---|---|
| Reply to an enquiry | within 24 hours | days of waiting |
| Who replies | the engineer who runs your project | a manager who passes questions on |
| Stages | design, assembly, test, enclosure, packaging — together | each stage with a different supplier |
| Confidentiality | NDA before files; we never publish clients | NDA on request, after negotiations |
| Communication | Signal, Telegram, phone, email | email or a web form |
| Quality control | IPC-A-610, ESD protection, a test report for every batch | results without a report |
| Batteries | every cell tested, test sample available | no incoming-inspection data |
How we work
Five steps — you see the result at each one
-
01
Free review
We check your Gerber, BOM or spec for manufacturability and suggest substitutes for scarce parts.
You get: findings and a quote within 24 h
-
02
Design
If needed — schematic, PCB layout, firmware, 3D enclosure model.
You approve the design before production
-
03
Sourcing and incoming inspection
Genuine components from trusted distributors, incoming test of battery cells.
You know exactly what goes into your product
-
04
Pilot batch
Assembly, flashing and functional test of a few units.
You check the samples and green-light the series
-
05
Series and shipping
Every unit tested, packed and shipped by courier or Nova Poshta.
You receive the units and the batch report
One team — one point of responsibility
Design, firmware, 3D modelling, assembly, testing and packing happen in Kyiv under our engineers’ control. You talk directly to the people responsible for your product — no middlemen, no hand-offs between suppliers.

Need a different configuration? We build to your platform — any S/P count, form factor and connectors.
Fiber optics
Fiber-optic spools for the range you need
We match spool length and weight to your drone and mission.
- Length: 5–20 km
- Single-mode fiber G.652.D / G.657.A1/A2 — resistant to micro-bending
- Attenuation below 0.35 dB/km; SC/APC, LC/APC connectors
- 100% checked with an optical time-domain reflectometer (OTDR)
Quality and confidentiality
We answer for the result, not just the soldering
IPC-A-610 and a report per batch
Assembly and acceptance to IPC-A-610 at ESD-protected workstations. A functional test report for every batch; for batteries — capacity and internal resistance.
NDA before we start
A mutual NDA before any documents change hands; e-signature available.
Closed loop
We never publish clients, products or the production address. Only your project’s engineers see your documents. We show examples of our work in person, after an NDA is signed.
Made in Ukraine
Design and assembly in Kyiv — higher local content for your product and a shorter supply chain.
FAQ
Frequently asked questions
What is the minimum batch?
From 100 pcs; before a series we build a few samples for you to check.
What files do you need for a quote?
Gerber, BOM and a pick-and-place file for assembly; for design work a spec or task description is enough. Details on the file requirements page.
How do you protect our documentation?
We sign an NDA before files are shared; only the project team has access. We never publish clients or the production address.
Can we get a test battery?
Yes. Tell us in the form which pack and platform you need — we will agree the terms.
Do you give a warranty?
Yes, and the term depends on the product: typically a few months for UAV boards and up to 12 months for civilian electronics. The exact term is fixed in the contract. For products used in combat conditions we guarantee compliance with the test report at the time of shipment.
Why are there no photos of your work?
Most of our projects are for defence, and clients do not want their designs seen by others. We show examples in person after an NDA is signed — and we will protect your project the same way.
Who sources the components?
Whatever suits you: turnkey by us, consigned by you, or mixed. Genuine parts only, from trusted distributors.
Do you work with foreign companies?
Yes — under a contract with invoices and full shipping documents. We correspond in English and Ukrainian. Test batches from 100 pcs are invoiced by a sole proprietor (FOP) on the single tax, without VAT. Serial production contracts are signed with a VAT-registered LLC (TOV), which we set up before the series starts — while components are being sourced and stencils made.
What are the lead times?
They depend on product complexity and component availability. We state exact lead times in the quote and fix them in the contract.
How do you ship?
Nova Poshta, courier, or international delivery by agreement.
