What is Electronic Manufacturing Service?
Electronics Manufacturing Services (EMS) applies to the entire industry as well as to a specific class of subcontractors or companies. It is often used interchangeably with the term Contract Manufacturing Services (CMS) or Contract Electronics Manufacturing (CEM). Electronics Manufacturing companies provide a very broad range of manufacturing and accompanying services, such as supply chain management, engineering and product management support, as well as after sales support. Designed especially for OEMs, the services of EMS providers allow manufacturers to focus on their core business, i.e., product research and development, as well as sales and marketing of their devices.
Electronic manufacturing services are also called electronic EMS, electronic contract manufacturing. If the company announces they provide an electronics manufacturing service, it can provide service of electronics design, manufacturing, testing, distribution, storage, logistic, return/repair, etc.
Electronics Manufacturing Services (EMS) providers are those companies that provide both original equipment manufacturers (OEMs) and end-users with electronic products and services. These include PCB and electronics design, manufacturing, testing, supply chain management, and repair and maintenance.
Electronics Manufacturing Applications
From various industrial sectors up to the medical industry, more and more OEM’s are increasingly searching for electronic manufacturing services. Gone are the days when OEMs decided to work with a contractor for purely operational and strictly assembly-only reasons. Today, it is part of a well-thought-out overall business strategy.
Indeed, manufacturers have discovered that with a collaborative approach, they can achieve significant benefits that improve their customer service and quality of their products, as well as enable them to react faster to dynamic market changes. Thus, the total costs are reduced and OEMs achieve a value they would have a hard time to build on their own.
A few critical applications and their specifics that are worth having a glance at, are:
Medical devices: OEMs from the healthcare industry look at adequate certifications (ISO 13485), as well as tight process control and above average quality standards at the electronic manufacturing provider.
Industrial automation devices: a broad segment of devices that relate to industry-related devices, mainly used for control and automation of various processes. EMS providers supporting industrial electronics are required to be able to adequately manage high-mix low-volume production and support a variety of processes for OEMs (printed circuit board assembly, conformal coating, final assembly, electro-mechanical integration, testing).

What are the capabilities of Electronics Manufacturing Services providers?
One of the main services offered by the electronics manufacturing services providers is the Printed Circuit Board Assembly (PCBA) capabilities. Currently, the technological advancements allows a very fast and high-quality assembly, due to precise components placement capabilities. A sophisticated SMT assembly line is priced even on the level of millions of dollars, thus it may be an extremely high investment for an OEM. However, if they leverage the fact that the electronics manufacturers produce for a variety of Customers, they can gain access to a modern, fast, and flexible production lines for assembling complex electronic boards at a reasonable price.
Furthermore, many EMS companies provide assembly processes for combining printed circuit board assembly, together with cable harnesses assembly, box build or electro-mechanical assemblies along with the testing procedures. This provides the complete assembly services, where the OEM gets a complete offer and does not have to at all be involved in the production process at all.
The scope of services that electronic manufacturing services companies provide will vary one from another, depending on their strategy and capabilities. In summary, you can expect the following assembly services:

The Process of Electronic Manufacturing Services
1. DFM/DFA
PCB file checking
PCB file checking is an essential step in the PCB manufacturing process. It involves verifying that all elements of a PCB design have been appropriately created and placed to ensure that it meets the customer's requirements.
PCB file checking also ensures that errors or mistakes are identified before production begins, thus avoiding costly delays or rework. As a result, manufacturers can guarantee quality control throughout their production process through thorough PCB file checking.
BOM list check
BOM list check is an essential step in the electronic manufacturing process. It ensures that all of the components used in a product are present, accounted for, and fit for purpose. BOM list checks also help identify discrepancies between what has been ordered and delivered to the production line.
By thoroughly checking BOM lists before assembly begins, manufacturers can ensure that their products are made with quality components and materials. Without a BOM list check, it's impossible to manufacture higher-quality finished goods with fewer defects or problems down the road.
2. PCB Fabrication & Parts sourcing
PCB Fabrication
PCB fabrication is the process of creating printed circuit boards (PCBs). PCBs can be made with different materials and techniques, depending on the application they will be used for.
The fabrication begins by designing a PCB layout that meets the device's specifications. Once this design is complete, it must be manufactured to create an actual board.
The following steps involve etching copper onto a substrate such as a fibreglass or ceramic, drilling holes for components and connections, and then soldering components into the board.
After these steps are completed, PCB testing must occur to ensure functionality before it can be sent off for use in its intended device.
PCB fabrication is a complex but necessary process that must be done precisely to ensure the PCB works as expected.
Electronics Parts sourcing
Electronics parts sourcing is locating and supplying electronic components, such as semiconductors, resistors and capacitors, for use in electronic devices.
It involves researching suppliers that offer quality products at competitive prices, negotiating pricing and delivery terms, and ensuring components meet safety regulations.
As electronics become increasingly complex, electronics parts sourcing has become essential to the engineering process.
By outsourcing this task to experts who understand the complexities of electronics parts sourcing, businesses can ensure they are getting reliable supplies at reasonable costs. Additionally, electronics parts sourcing professionals can provide valuable insight into the latest trends in electronics components and help ensure that any new electronics designs comply with relevant safety regulations.
Ultimately, electronics parts sourcing allows businesses access to the components they need when they need them at a price that works for their budget.
3. PCB Assembly
SMT assembly, or Surface Mount Technology assembly, is an electronic manufacturing process that involves placing components onto a printed circuit board (PCB). SMT is one of the most widely used methods in modern electronics production thanks to its low cost and high efficiency. SMT assembly requires specialized tools and processes for mounting components on both sides of the PCB at once. This method offers excellent flexibility regarding component placement and improved electrical performance over traditional through-hole technology. SMT also allows for faster turnaround times compared to other electronic assemblies, given its automated nature and advanced automation solutions such as pick-and-place machines. SMT assembly is especially suited for high-volume production, which explains why it is highly sought-after for large-scale manufacturing.
4. IC programming
IC programming is an essential part of electronic manufacturing, playing a crucial role in developing and producing devices such as smartphones, computers, and other consumer electronics.
IC programming involves writing code that tells integrated circuits (ICs) how to behave when installed in a device. This code can include instructions on how the IC should interact with other components within the system and the tasks it should perform.
IC programming is also used for testing during design verification and debugging, ensuring that ICs are functioning correctly before being shipped out to customers.
With its importance across many industries, IC programming has become an invaluable skill set for those looking to break into or advance their careers in electronic manufacturing company.
