The company
A human-scale industrial SME, specialised in R&D and manufacturing of electronic products from Langres, France.
Codium was founded on a simple observation: SMEs and mid-sized companies that need electronic boards in medium series lack suitable partners. Too small for the large EMS manufacturers, too big for craft workshops.
We created Codium to fill that gap. A design office of senior engineers, paired with an electronics production line able to compete with the best — but with the reactivity and proximity of an SME.
Based in Langres, in Haute-Marne, we are proud to manufacture 100% in France, with controlled lead times and full traceability.
Codium was founded by four partners with complementary profiles. Each brings high-level expertise — gained in industry, in a research laboratory or internationally — and oversees their domain from end to end.
Electronics engineer
6 years of experience in an electronics design office within SME subcontracting. Thomas has an in-depth understanding of the challenges and constraints of modern industrial design — from schematic capture to series industrialisation.
Electronics engineer · PhD in computer science
A dual industry and research profile: electronics engineering in an industrial setting and a PhD in a university laboratory. A specialist in sensor networks and embedded systems security — a rare combination that few SMEs can afford in-house.
Electronics engineer · RF specialist
With a background in antenna development for mobile devices, Pierre masters RF design, anechoic chamber testing and wireless product qualification from end to end. A sharp, rare expertise, available directly within Codium — with no external subcontracting.
Business engineer
A dual technical and commercial skill set, with experience in France and abroad managing high-tech projects. Mathieu acts as the interface between the engineering teams and customers, from the first conversation to series delivery.
A direct point of contact, no complex hierarchy. You speak to the engineer who designs your board or the operator who manufactures it.
Zero compromise on quality. Every board is tested, every batch is traced. Our processes are documented and repeatable.
We adapt to your constraints: variable volumes, urgent lead times, BOM changes. None of the rigidity of a large organisation.
We keep our commitments. Lead times, quality, confidentiality. You can count on Codium as a long-term partner.
Activity 01
Design, development and industrialisation of electronic boards. Our senior engineers work on your IoT, embedded, industrial or power projects — from schematic to certified prototype.

A complete industrial line. SMT and through-hole assembly, AOI/ICT testing, integration and shipping. Optimised for 1,000 to 5,000 boards per year per project — with no volume ceiling.
Learn moreOur production workshop is based in Langres, in Haute-Marne. This strong local anchoring allows us to guarantee full traceability and a short production loop — a real advantage in terms of lead times and reactivity.
We have invested in a modern production line, able to handle complex boards with the same quality rigour as the largest players in the sector.
Codium has benefited from the support of institutional partners in its development.
What customers ask us before entrusting us with a project.
Codium is an industrial SME founded and run by its four founding partners, with no outside shareholders and no group structure. No complex hierarchy: the people who make the decisions are the ones who design and manufacture your board.
Directly to an engineer. The first conversation takes place without an intermediary salesperson, with the person who will assess the feasibility of your project — and often the one who will go on to design it. This is a deliberate choice: fewer layers, greater reactivity.
Yes. Our size is precisely what lets us be responsive: quotation within 48h on a complete file, no lengthy internal approval chain, and real flexibility on volumes and urgent lead times — something a large organisation cannot offer.
The design office and the production line are under one roof, in Langres. The engineer who designs the board also follows its manufacture — which removes the usual friction between design and industrialisation. And you keep a single point of contact from the first conversation to series delivery.
Let's talk. The first conversation is always without commitment.
