Electronic Manufacturing Service (EMS)
What Is An Electronic Manufacturing service?
Electronic Manufacturing service is called EMS, a thriving service in the industry in the 21st century as electronics are becoming more and more important in our lives. Electronic manufacturing service is a manufacturer that provides design, assembly, production, and electronic components test and printed circuit board (PCB) assemblies services for original equipment manufacturers or the brand owners.
EMS companies may contract with other manufacturers in the manufacturing process. Some companies may require only a design file provided by the customer before arranging to develop the product, source the components from a trusted components distributor, and assemble and test the product. Alternatively, EMS providers specializing in the assembly may require the customer to provide the design files, the necessary components for manufacturing, and an assembled sample. EMS companies can provide additional services, such as routing the PCB or through another contractor.
Electronic manufacturing involves different levels of automation, depending on the customers and projects. Companies that produce large runs of products use heavily automated manufacturing. Providers specializing in prototypes or small production manufacturers typically assemble PCBs manually to save the time and cost of setting up automated assembly equipment.
What Can Electronic Manufacturing Service Providers Do?
- Design is one of the services that the electronics manufacturing service providers are capable of doing. Design services contain several related actions after a customer’s specifications, or product needs are determined before manufacturing or assembly. The EMS company may first provide a product concept with details about the project’s main objectives and preliminary specifications. The company may research by interviewing product users, consulting experts, and exploring existing related products. After these two steps, the company develops, visualizes, manufactures, and tests the product and then sends a final prototype to the customer for approval.
- Manufacturing is the essential part when referring to EMS companies. Electronic manufacturing companies may specialize in one or more than one areas of manufacturing technology and production size. Also, Electronic manufacturing may contain several different types of electronic products. Printed circuit boards, or PCBs, are bare boards without holding any components. EMS providers populate the PCBs with elements to create printed circuit assemblies (PCBAs) and may have the capability to work with several different types of boards. PCBs are assumed to be rigid and manufactured as stiff and inflexible boards. Flexible PCBs can bend and accommodate flexible circuits used in instrumentation, automotive, and medical applications. Rigid-flexible PCBs are rigid boards with flexible interconnects.
Manufacturing Includes Assembly Technology
The EMS companies may also specialize in one or two assembly technology. Through-hole Technology assembly (THT) and Surface Mount Technology assembly (SMT).
A. Through-hole technology includes mounting components by inserting their leads through the drilling holes in the PCB. The technicians are then soldering the leads on the opposite side of the PCB. Through-hole components are typically soldered manually or wave soldered to a PCB in a production line.
B. Surface mount technology components are soldered to the board’s surface and are usually smaller and less expensive than through-hole components. Modern pick-and-place equipment can rapidly and accurately populate surface mount components from a manufacturing perspective.
What Kind Of Volumes Can The EMS Company Do?
EMS companies may specialize in several different production volumes within their available equipment and capabilities. For example, prototypes, some providers build prototypes, which are still early samples at stages made to test a product’s concept, following the design phase. Prototype build ensures that the product will meet the expected purpose after being manufactured as part of a more extensive production run. Technicians make prototypes with relatively cheaper materials than those used in the production process. In the past, electronics manufacturers built prototypes using breadboards and THT components. Still, the widespread availability of custom prototype PCBs allows manufacturers to produce prototypes that closely mirror the intended product.
- Prototyping may occur multiple times in a project’s design and planning stages.
- Mass production: EMS companies often specify their production volume capabilities. Although
production volume file requirements are relative. General guidelines can be set as follows:
- A: Low volume providers produce small quantities, typically 1 to 100 products. Low volume is often similar to prototyping.
- B: Medium volume providers can produce around 100 to 10,000 pcs products annually.
- C: High-volume manufacturers can produce over 10,000 units annually.
- D: Specialty Production: Electronics manufacturers may also require special techniques, including quick-turn production and cabling services. Quick turn manufacturers can assemble PCBs within a short time, about three days, after receiving all components. Cabling manufacturers attach cables to electronic assemblies(PCBs).
PCB Assembly Test
Once the PCB has all the necessary installed components and passes the SMT assembly line, technicians use an online AOI machine to verify that it fits the customer’s CAD data. The circuit board of the bottom terminal assembly will be x-ray-checked to ensure the accuracy of component placement.
Each component can then be tested online and functional by a dedicated test technician following customer specifications. The practical test bench used in the above process can be as simple as a set of electronic measuring equipment on the workbench or as complex as a six-foot frame-style integrated test system. While many customers choose to provide functional testing equipment, Venture PCBA engineers have the full ability to design and build custom operational testing systems.
Technicians configure it to meet the needs of customers’ products for applications in harsh environments such as humidity, temperature, and corrosion.
