What is Electronic Manufacturing Services

Electronic Manufacturing Services (EMS) refer to a range of services provided by companies that design, test, manufacture, distribute, and provide return/repair services for electronic components and assemblies for original equipment manufacturers (OEMs). The concept is also referred to as electronics contract manufacturing (ECM).

Electronic Manufacturing Services (EMS):

• EMS refers to companies that offer a wide range of manufacturing services including design, assembly, and testing of electronic components and PCB assembly for OEMs.
• EMS providers focus on the actual production and are often involved in the entire lifecycle of a product, including after-sales services and repair.
• They may also provide supply chain management services, helping OEMs with logistics and material procurement.
  

  Original Equipment Manufacturers (OEM):

• OEMs are companies that design and own the product. They are the ‘original’ creators and hold the intellectual property rights to the product.
• These companies may or may not have their own manufacturing facilities. When they don’t, they outsource manufacturing to EMS providers.
• OEMs are primarily responsible for the innovation, design, and branding of the product. Their core strengths lie in R&D, marketing, and product development.
  

  Electronics Contract Manufacturing (ECM):

• ECM is essentially another term for EMS. However, ECM often emphasizes the contractual nature of the relationship between the manufacturing service provider and the OEM.
• Like EMS providers, ECM companies manufacture, test, distribute, and provide return/repair services for electronic parts and assemblies for the OEMs.
• The term ECM may be used more specifically to denote the contract or agreement aspect of the manufacturing services, highlighting the service-level agreements, terms, and conditions between the OEM and the service provider.

• Market Growth:

The electronic contract manufacturing and design services market was valued at USD 515.1 billion in 2022 and is expected to grow at a CAGR of 9.7% from 2023 to 2030​​​​.

• Outsourcing Trends:

Original Equipment Manufacturers (OEMs) are increasingly outsourcing design and engineering services to reduce costs and improve flexibility​​.

• Sector-Specific Growth:

Significant growth in demand for electronic contract manufacturing services is observed in healthcare, automotive, aerospace & defense, and industrial sectors​​​​.

• Regional Dominance:

The Asia-Pacific region, especially China, has been the largest market due to the availability of raw materials and low-cost labor. It is expected to maintain this dominance during the forecast period​​​​.

• North America and Europe:

Growth in North America is driven by the healthcare and automotive industries. Europe’s market growth is fueled by a strong focus on innovation and technology with many companies outsourcing their electronic manufacturing needs​​.

• Electronic Manufacturing Services (EMS) Market:

The EMS market size was around USD 500 billion in 2022, projected to grow at a CAGR of over 5% from 2023 to 2032, driven by the increasing penetration of smart devices and demand for consumer electronics globally​​.

• Service Segmentation in Electronics Manufacturing Services:

The EMS market includes services like electronics manufacturing, engineering services, test & development implementation, and logistics services. The electronics manufacturing segment, especially PCB assembly, is expected to see significant growth​​.

PCB and PCBA Design & Engineering services

• Design for Manufacturability (DFM)

This is a key aspect where the design is optimized to make it easier and more cost-effective to manufacture. It involves considerations like the selection of materials, component placement, and assembly methods to ensure efficiency, reliability, and cost-effectiveness in mass production.

• Design for Testability (DFT)

Alongside DFM, DFT is employed to ensure that the product is designed in a way that makes it easy to test during the production phase. This includes planning for test points, test procedures, and diagnostic capabilities.

• Advanced Engineering Services

Some Electronic Manufacturing Services providers offer advanced engineering services such as simulation and analysis (thermal, mechanical, electromagnetic), advanced PCB design techniques, and specialized expertise in areas like RF/wireless design, embedded systems, and power electronics.

• Compliance and Certification

Electronic Manufacturing Services providers also assist in ensuring that the product meets all relevant industry standards and certifications. This can include safety, environmental, and regulatory compliance like FCC, CE, UL, RoHS, etc.

PCB Manufacturing

• Single-Sided PCBs
• Double-Sided PCBs
• Multilayer PCBs
• Flexible PCBs
• Rigid PCBs
• Rigid-Flex PCBs
• Aluminum Backed PCBs
• High-Frequency PCBs

Electronic components sourcing

• Electronic Manufacturing Services providers often have established relationships with a wide range of suppliers and distributors. These relationships enable them to source components efficiently and at competitive prices. They may also have access to global supply chains, which is beneficial in sourcing rare or hard-to-find components.

• Due to the scale of operations, EMS providers can purchase components in large volumes, which typically results in cost savings. These savings can be passed on to the OEMs, making the overall manufacturing process more cost-effective.

• By efficiently managing the sourcing process, EMS providers can reduce lead times, which is crucial for faster time-to-market for new products or meeting tight production schedules.

Assembly Service of Electronic Manufacturing Services

• PCB Assembly:

SMT: Components are mounted directly onto the surface of a PCB. SMT allows for more components to be mounted on a smaller area, enabling the production of compact and complex electronic devices.

THT: Components with leads are inserted into pre-drilled holes on the PCB and then soldered. THT is often used for components that need to endure mechanical stress or high temperatures.

• Cable and Wire Harness Assembly
• Electromechanical Assembly
• Prototype Assembly

Testing services of Electronic Manufacturing Services

• In-Circuit Testing (ICT)
• Functional Testing
• Automated Optical Inspection (AOI)
• X-Ray Inspection
• Burn-In Testing
• Electromagnetic Compatibility (EMC) Testing
• Flying Probe Testing

• Outsourcing can significantly reduce labor costs and expenses related to maintaining manufacturing facilities. Electronic Manufacturing Services providers often have economies of scale and can purchase raw materials at lower costs due to their larger volume purchases.
• By outsourcing manufacturing, a company can focus more on its core activities such as research and development, product design, and marketing. This strategic focus can lead to innovation and improved products.
• Electronic Manufacturing Services providers usually stay up-to-date with the latest manufacturing technologies and processes. Outsourcing can give companies access to these advanced technologies without the hefty investment.
• Professional Electronic Manufacturing Services providers have established quality management systems and are often certified with industry standards such as ISO 9001. They ensure products meet regulatory compliance, reducing the risk for the hiring company.
• Outsourcing allows for greater flexibility in production. Companies can scale up or down quickly in response to market demands without the need for significant capital investment or changes to their own facilities.
• With their expertise and resources, Electronic Manufacturing Services providers can often reduce production lead times, enabling products to reach the market more quickly.
