What is Electronic Manufacturing Service?
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.

The Process of Electronic Manufacturing Services-12 Steps
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 fiber glass 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.
PTH assembly, or Plated Through Hole assembly, is a method of mounting electronic components onto printed circuit boards. PTH assemblies typically comprise pins inserted into the board’s holes and then soldered in place. PTH assemblies provide robust mechanical connections for electrical components, making them ideal for high-reliability applications such as automotive electronics or medical devices. PTH assemblies can also create complex circuits with multiple layers of copper traces and pads on both sides of the board. With proper design and quality assurance procedures, PTH assemblies offer reliable performance over a long service life while providing cost savings due to their relatively low material costs compared to other soldering techniques.
