Imagine that you have come up with a smart meter, a scientific instrument, or an industrial control device, and you need to find the right company that will produce it for you in bulk. In this case, your partner should be EMS, a company that offers electronic manufacturing services, such as PCB assembly, assembly of a finished product, product testing, and shipping, thereby freeing you from worrying about the manufacturing process itself and allowing you to focus on designing and selling your product. At the same time, France is now among the leading countries providing EMS services and has developed a number of contract manufacturing companies.
The purpose of this website is to explain the meaning of EMS, give a brief overview of the leading companies in the industry such as Asteelflash, Lacroix Electronics, ALL Circuits, Eolane, Cofidur, and ICAPE, and provide readers with helpful tips on how to select EMS partner for their product.
Summarizing everything, Electronic manufacturing services (EMS) can be viewed as outsourcing facilities provided by an external partner engaged in assembling, testing, and delivering products on behalf of a client. The largest representatives of EMS market in France include Asteelflash, Lacroix Electronics, ALL Circuits, Eolane, Cofidur EMS, ICAPE Group, and Serma Group. French EMS companies are known for their service of high-mix medium volume products, compliance with rules and regulations, as well as proximity to their clients in Europe.
What Are Electronic Manufacturing Services (EMS)?
Services related to electronic manufacturing are sometimes referred to as manufacturing services and include PCB assembly services provided by companies that manufacture electronic products on behalf of another company. For example, when a brand designs a product, it doesn’t manufacture the product itself, but rather partners with EMS. Typically, a complete EMS includes the following services:
- Initial PCB assembler (PCBA): mounting and soldering parts on circuits and boards, including SMD, THT and mixed technologies
- Box build / system assembly: adding finished PCBA with all the necessary parts, like connectors and cable.
- Design services: designing for manufacturing (DfM), designing for testing (DfT), designing for costs, and designing for purchasing.
- Testing: ICT (In-Circuit Testing), flying probe testing, functional testing, boundary scan testing and burn-in test.
- Supply chain: From sourcing components and purchasing goods to managing inventories and disposing of stock no longer used.
- Support services at the back end: repair, refurbishment and returns from the field.
- Logistics: warehousing and packing and shipping.
There is a key differentiator between EMS companies and ODM companies: whereas an ODM produces a product using its own intellectual property, an EMS develops your design only. In France, EMS businesses often design products without their own intellectual property rights. The same technique can be applied to electrical and electronic industries as well: e.g. circuit breaker manufacturers and switchgear producers provide the certified protection component for products manufactured by EMS companies.

What Services Do EMS Companies Provide?
When comparing EMS quotes, make sure you understand which services are included, because the scope can vary dramatically:
| Service Layer | Typical Deliverables | Usually Included? |
|---|---|---|
| Component procurement | Sourcing, buying, and kitting all components | Yes, core EMS service |
| PCB fabrication | Manufacturing the bare circuit boards | Sometimes (often subcontracted or via partner) |
| PCB assembly | SMD/THT placement and soldering | Yes, the core service |
| Testing | ICT, flying probe, functional, burn-in | Yes, at basic level; advanced test design may cost extra |
| Box build | Final product assembly into enclosure | Often, at additional cost per complexity |
| Design engineering | DfM/DfT review, design changes | Usually quoted separately |
| Aftermarket | Repair, refurbishment, spares management | Optional service |
| Logistics | Warehousing, distribution, drop-ship | Optional service |
The most important principle when purchasing EMS services is to know the exact cost per unit given your specifications — low assembly cost can be deceiving when it comes alongside higher testing and NRE costs.The same discipline applies when your finished product needs power distribution components: specifying certified breakers and switchgear from the start, like the UL 489 certified breaker range from a manufacturer such as HUYU Global, avoids re-qualification costs downstream.

How to Choose the Right EMS Partner
A hardware company’s decision about the selection of its EMS provider is one of the most essential topics for discussion in its supply chain management. Below is a two-step process to follow during the choice of an EMS provider:
- Clearly define the product profile. Analyze the annual production volume, number of types of goods (whether they are high-mix or low-mix), technical difficulty of the products (number of layers, technology), and testing requirements related to the products. For example, Asteelflash and other high-mix companies are too high-profile and highly-priced for the production of easy single mixed boards, while some Asian low-mix manufacturers are not able to produce complicated medical devices.
- Check if the certifications correspond to the product’s needs. Some medical equipment may require ISO 13485 certification, aerospace technologies should be certified according to EN 9100 standard, and automotive manufacturing requires the products to meet the IATF 16949 standard. It is important to obtain relevant documents instead of taking the company’s word for it.
- Determine the buying power of the EMS providers. Nowadays, having ability to buy the components is more important than producing at a low price, therefore knowing about the availability of the preferred suppliers and the systems of management of obsolescence is essential.
- Request DfM information in advance. A good EMS conducts a design review, which allows estimating whether the manufacturer is mature enough to start producing.
- Conduct factory audit. It is obligatory to perform onsite audits in industries such as weapon building, medicine, and automobile manufacturing.
- Compare total landed cost instead of just looking at unit prices. Consider costs connected with tooling/NRE, test fixtures, freight, duties, safety stock, and yield, rather than looking at the price only. A 10% higher unit price at 99.8% yield often beats a cheap quote at 97% yield — the same reasoning that leads panel builders to balance certified component cost against rework risk when selecting MCB hardware for their distribution boards.
What Does EMS Cost?
EMS pricing is heavily project-specific, but these 2025-2026 benchmarks give a realistic sense of the market:
| Service / Scenario | Typical Cost Range |
|---|---|
| PCB assembly setup / NRE (tooling, programming) | $500 – $10,000 depending on complexity |
| Simple 2-layer board assembly (per board, at 1k-10k volume) | $1 – $8 |
| Complex 8-12 layer board assembly (per board, low volume) | $20 – $150+ |
| Box build assembly (per unit, medium volume) | $5 – $80+ depending on mechanical complexity |
| ICT / functional test fixture development | $3,000 – $30,000 |
| Component sourcing fee (percentage of BOM) | Typically 5-15% of component cost |
| Full product launch program (design to mass production) | $50,000 – $500,000+ |
French EMS providers typically charge about 30-60% more for assembly costs than Asian high-volume factories; however, French EMS providers win through faster delivery time (days instead of weeks to deliver to the EU), strong compliance, design engineering assistance, and reduced risk of regulatory issues.
Frequently Asked Questions
What is the difference between EMS and ODM?
The EMS firms create products designed by clients themselves by manufacturing, testing, and shipping them. On the other hand, ODM firms produce items based on their own technology. They may even sell these goods as a client-own product. Quite a few firms find both of them useful. Companies like Eolane and Lacroix are examples of French companies providing both options to their clients.
Which country has the largest EMS industry?
China and Taiwan produce the greatest quantity of EMS products, with global dominance going to Foxconn (Taiwan/China), Pegatron, Quanta, and USI. In Europe, the largest companies include Asteelflash (France), Zollner (Germany), and Nedap/Kitron (Northern Europe). France boasts one of the top EMS markets in Europe for complex and regulated electronics.
How much does it cost to start EMS production?
Budget an amount that ranges from $5,000-$50,000 for the first non-recurring engineering (NRE) and implementation of an average circuit board. This should include assembly programming, test equipment, tooling, and first article approval that precedes the costs of the manufactured products. A simple circuit board can be produced for less than $10,000 while an advanced regulated product can costs up to $100,000 for engineering and qualification.
How do I know if I need an EMS partner?
You probably require the services of an EMS partner if your internal team is spending all its time manufacturing instead of designing products, if your production volume has surpassed the capabilities of hand-assembly shops, if you require specialized certifications (such as ISO 13485, EN 9100), or if obtaining components is taking up too much time for your engineers. When production is at around 500 boards per year or less, and there is no need for certifications, working with a PCB assembly prototype shop tends to be less expensive than forming a partnership with an EMS provider.

Conclusion
Although the electronic manufacturing services industry of France is not large in size as compared to that of Asia, its offerings are worth it: they are flexible concerning production and meet high quality requirements compatible with those used in the aerospace area, and at the same time are very close to the market, have well-developed IP protection mechanisms, and boast very good engineering design skills – the ones many Asian companies do not have. The key player in the electronic manufacturing industry in Europe is Asteelflash.
When it comes to choosing the right EMS company, it is necessary to take into account the characteristics of your product, e.g., if your product is sensitive, it is better to select a French or EU EMS company; in case your goal is to get the lowest price, Asian EMS providers would suit you best. The most favorable solution includes a combination of the two – using a European company for prototyping and an Asian company for mass production. Whatever option you choose, you always need to define the specifics of your project, check the certificates and compare the prices for manufacturing in different countries.
