Electronics Manufacturing Services: Why Do You Need Them?
January 21, 2025
Electronics manufacturing services (EMS) is a broad industry that involves outsourcing electronic product design, manufacturing, testing, and distribution to specialized companies. With the growing demand for consumer electronics and innovative technological advancements in various industries, partnering up with an EMS company can bring huge success to your business.
What are Electronics Manufacturing Services?
Electronics manufacturing services refer to firms that design, manufacture, test, distribute, and repair electronic components for original equipment manufacturers (OEMs).
They offer a range of electronic design services (e.g., concept development, industrial design, engineering, prototyping, quality control and validation, and production support) to various sectors, including industrial control, medical, military, communication technology, power supply, automotive, and new energy.
What Does an Electronics Manufacturing Services Company Do?
EMS companies specialize in the design and production of electronic devices for OEMs. They offer a comprehensive range of services, including design, assembly, testing, and often supply chain management. By outsourcing these complex production processes to EMS providers, OEMs can leverage their expertise, reduce costs, and streamline their operations. This, in turn, grants OEMs more time and resources to focus on their core competencies like product development and sales.
What is the Difference Between OEM and EMS?
The core difference is that OEM focuses on producing completed products in-house, with a greater emphasis on research, development, and innovation, while EMS is a contract manufacturer that designs, manufactures, tests, ships, or repairs electronic components and assemblies for other companies.
Here are the primary distinctions between the two manufacturer types:
OEM
EMS
Typically use equipment designed for mass production of their specific products, meaning setups take time but are efficient once running.
Use flexible machines that allow quick changes between projects, albeit sometimes at slower speeds.
Introduce new items less frequently and have less need to share detailed manufacturing instructions.
Due to dealing with a wide range of industries, EMS must have a refined and robust New Product Introduction (NPI) process to handle the diverse and frequent product launches.
Typically focuses on a narrow product range.
Has expertise in testing a wide range of products.
Focuses on sourcing for their specific product lines.
Manage a global supply chain to support the production needs of diverse customers.
What Are the Processes Involved in EMS?
The electronics manufacturing service process involves several key stages, each essential to ensuring the production of high-quality electronic devices:
Design: The first step involves developing a detailed blueprint of the product. Engineers typically use Computer-Aided Design (CAD) tools to map out the electronic components and circuitry of the device.
Prototyping: Building prototypes will help test a design’s feasibility, helping electronic manufacturing services companies refine the product before moving into mass production.
Material sourcing: EMS firms will source the materials needed to build the product. These include semiconductors, resistors, capacitors, metals, and plastics crucial for manufacturing electronic components.
PCB fabrication: The Printed Circuit Board (PCB) is made through a multi-step process involving etching, layering, drilling, and soldering. This board will then serve as the foundation for the other components.
Component assembly: Once the PCB is fabricated, the components are laid onto the board. This is done using Surface Mount Technology (SMT) or Through-Hole Technology (THT), depending on the type of product being manufactured.
Soldering: Once the components have been put in place, they are then safely secured to the PCB using soldering. This is the process of bonding parts to the board using a molten metal alloy.
Testing: The device undergoes rigorous testing to find and correct any defects in the circuitry and assembly. Common methods include functional testing, burn-in testing, environmental testing, and automated optical inspection (AOI).
Final assembly: The PCB and other components, such as displays, buttons, connectors, and cables, are assembled into the enclosure.
Quality control: Throughout the EMS process, quality control measures are implemented to ensure that the products meet the required standards. These tests include Serial Peripheral Interface (SPI), X-ray, and First Article Inspection (FAI).
Packaging: Once the electronic product passes quality assurance, it is finally packaged appropriately for distribution.
