Our process
From order
From order
to shipping
1
Purchasing & procurement
Sourcing and procurement of all electronic components, including specific or long lead-time parts. Stock management and batch-level traceability tracking.
2
Industrialisation
Development of PCB tooling, creation of functional test benches, definition of assembly instructions. Validation of the manufacturing file before series launch.
3
Manufacturing
SMT assembly by reflow soldering and through-hole components by wave soldering. Line equipped for BGA and QFP packages and power components.
4
Quality & Testing
AOI (automated optical inspection) after soldering, ICT (In-Circuit Test) and functional testing. No untested board ever leaves the workshop.
5
Packaging & Shipping
Anti-static packaging to your specifications, batch/serial labelling and shipping from Langres with full traceability.
Our capabilities
A complete industrial line
Through-hole components
Insertion and wave soldering of through-hole components (THT). Transformers, connectors, power components and mixed-technology components.
AOI inspection
Automated optical inspection after each soldering step. Detection of solder defects and of missing, reversed or misplaced components.
ICT & Functional testing
In-Circuit Test (ICT) to verify every component. Functional test to validate the electrical and software behaviour of the assembled board.
Integration & Wiring
Integration of boards into enclosures, wire harness assembly, electromechanical sub-assemblies. Preparation of complete sub-assemblies.
Packaging & Shipping
Anti-static packaging, boxing and labelling to your specifications. Shipping from Langres with batch/serial traceability.
Our models
How to work with us
Model 01
Design + Production
You have a project, an idea or a specification. Our engineers in the design office design your electronic board, build the prototypes, then launch production on our industrial line.
Model 02
Production only
You have a complete manufacturing file (Gerber, BOM, assembly instructions). We produce your board on our line. You retain the intellectual property of your design.

SME responsiveness
Our production line competes with the best in terms of capacity and quality. We have invested in state-of-the-art equipment that lets us produce high-value-added boards, in compliance with CE certification requirements.
The difference with large contract manufacturers: you get a direct point of contact, controlled lead times, and a flexibility that large organisations cannot offer on medium series.

FAQ
Frequently asked questions
What volumes do you produce at Codium?
Our line is designed to be competitive on projects of 1,000 to 5,000 boards per year per project — the volumes where a genuine industrial partner makes the difference. But we also produce prototypes (a few dozen boards) and series well beyond 10,000 boards/year. No ceiling: every project is open for discussion.
Can I commission production only, without the design study?
Yes. Codium offers a Production-only model: you provide the complete manufacturing file (Gerber files, BOM, assembly instructions) and we produce your board. You retain the intellectual property of your design.
What are your production lead times?
Standard production lead times are 3 to 6 weeks depending on volume and board complexity. For urgent orders, we assess expedited lead times on a case-by-case basis. Local production in France gives us great responsiveness.
What tests do you perform on the boards you produce?
Every board goes through: visual inspection, AOI (automated optical inspection), ICT (In-Circuit Test) and/or functional testing. No board leaves the workshop without having been tested.
Can you handle component procurement?
Yes. Codium handles the sourcing and procurement of all components, including specific or long lead-time parts. We can also work with your own components if you prefer to supply them.
