Electronic Manufacturing Systems (EMS)
As the world’s leading trade fair for electronics, electronica brings developers, decision-makers, and supply chain managers from world-leading companies together with experts from EMS companies, and provides a central platform for exchanging experiences, technologies, and market trends.
Electronic manufacturing services (EMS) are far more than just contract manufacturing for electronic devices and assemblies. Today, EMS providers also handle key tasks along the entire electronics value chain: from engineering services, prototyping, PCB assembly, series production, testing, and quality assurance, to supply chain and obsolescence management, as well as lifecycle services. As a result, they are increasingly becoming strategic partners for electronics companies and supporting them in implementing complex projects.

Electronic manufacturing services at electronica
Ever-shorter development cycles, increasingly volatile component availability, rising quality requirements, and the need for scalable production processes are increasing complexity in almost all electronics segments and across all industries. That poses major challenges for companies in the electronics industry. EMS providers have recognized this and therefore help companies reduce complexity and better manage it from a technical, organizational, and economic perspective, and implement their projects quickly, securely, and efficiently.
As the world’s leading trade fair for electronics, electronica brings developers, decision-makers, and supply chain managers from world-leading companies together with experts from EMS companies, and provides a central platform for exchanging experiences, technologies, and market trends.
What are electronic manufacturing services (EMS)?
Electronic manufacturing services refer to services related to the contract manufacturing of electronic assemblies, modules, and systems. EMS providers manufacture on behalf of electronics companies such as original equipment manufacturers (OEMs) and system manufacturers, and, depending on the project scope, handle individual production steps or entire processes.
“EMS” is often used synonymously with “E²MS,” which stands for “Electronic Engineering and Manufacturing Services.” In addition to production, it also includes developing electronics. As such, E²MS providers support their customers as early as the design and development phase, hence offering a more comprehensive range of services than pure EMS providers.
Typical projects begin as early as the development and design of new products. In this phase, service providers offer support in areas such as “design for manufacturing,” “design for testability,” prototyping, material selection, and production planning. This is followed by the series phase which involves PCB assembly, component assembly, testing, quality assurance, packaging, and logistics. Relevant fields of application can be found, among others, in the following industries:
- Industrial electronics
- Automotive
- Medical technology
- Energy technology
- Telecommunications
- Mechanical engineering
What services do EMS providers offer?
The services offered by modern EMS providers range from technical development and engineering services to prototype construction and the series production of electronic assemblies. Core competencies are, in particular:
- Procuring the materials
- Assembling the PCBs, e.g., THT and SMD/SMT
- Mounting the assemblies
- Assembling the cables
- Installing the casing
- Device integration
- Quality assurance and testing
- Logistics and after-sales support, including repairs
A reliable procurement strategy is crucial, especially when it comes to critical components such as semiconductors, microcontrollers, or power electronics. Service providers support this process by managing suppliers, handling inventory management, and ensuring transparent material planning.
Another focus is on obsolescence management. For example, EMS partners provide support in evaluating end-of-life components, qualifying alternative components, and ensuring long-term product availability. In addition, they offer logistics and after-sales support, enabling companies to benefit from cost-effective, flexible, and high-quality products. EMS providers are able to handle both small and large production volumes and support various industries with specialized applications, depending on the respective project.
What benefits do EMS services provide?
EMS services offer companies the opportunity to reduce costs and use internal resources more efficiently by strategically outsourcing production components. By outsourcing production tasks to specialized providers, companies can focus more on developing new products, marketing, and sales. Collaborating with EMS partners provides access to specific expertise and technologies that may not be available in-house. That helps companies make their production more flexible and respond faster to market changes.
An overview of the benefits:
- Cost reduction: Companies save on investments in their own production facilities and personnel
- Expertise: Access to specialized knowledge and cutting-edge technology
- Flexibility: Faster adaptation to market requirements and product changes
- Scalability: Option of low and high volume production, depending on demand
- Focus: Companies can focus on their core competencies while outsourcing production
How do companies work with EMS partners?
The collaboration usually follows the pattern of a project run in several stages:
1. Technical clarification
2. Prototyping
3. Industrialization
4. Pre-series
5. Production ramp-up
6. Ongoing production
Close coordination between development, procurement, quality assurance, production, and the supply chain is crucial. By getting involved in development processes early on, EMS providers ensure that products can be efficiently manufactured, tested, and built with the right components. That reduces the need for later adjustments, improves process stability, and shortens time to market.
For international projects, EMS providers also look after coordinating global locations, suppliers, and logistics processes, making it easier to scale production capacity, and design flexible supply chains.
How do companies choose the right EMS provider?
The choice of an EMS provider should not be based solely on unit costs. Important criteria are:
- Technical expertise
- The level of vertical integration provided
- A targeted industry focus
- Sophisticated quality management
- Comprehensive certifications
- Sufficient testing expertise
- High scalability
- Long-term delivery capability
For technical decision-makers, manufacturing processes, test coverage, traceability, process data, and comprehensive engineering support are especially relevant. For procurement and the supply chain, on the other hand, the focus is on materials strategy, procurement network, transparency, risk management, and cost control. Management and business development also check whether the EMS partner is a strategic fit, can operate internationally, and is suitable for a long-term partnership.
What challenges and trends are shaping the EMS industry?
The industry faces several structural challenges. Fragile supply chains, shortages of semiconductors and microcontrollers, volatile prices, and increasing planning complexity continue to have a significant impact on electronics projects.
At the same time, increasing automation and digitalization are transforming electronics production. Process data, connected production systems, AI-powered planning, automated optical inspection, and digital traceability are becoming more and more important. As a result, EMS providers are increasingly becoming technology and process partners, instead of just manufacturing service providers.
Today, AI-powered methods in particular can support production planning, quality control, and process optimization. They require reliable process data, appropriate interfaces, investment in technology, and employee training.
