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.

5. PCB Testing & Inspections
AOI (Automated Optical Inspection) is a vital part of the electronic manufacturing process. AOI inspection is a non-destructive testing method to detect and identify printed circuit board (PCB) defects. It involves using optical technology such as cameras, lasers, or X-rays to scan each component on a PCB for abnormalities. In addition, AOI systems can be programmed to look for specific types of defects, including missing components, incorrect polarity, shorts between pins, misalignments between layers, and other issues that could cause product failure. Undoubtedly, AOI inspection provides manufacturers an efficient way to quickly and accurately identify potential problems before products are sent out for final assembly or packaging.
Visual inspection is a crucial process in electronic manufacturing company, as it helps to ensure that the electronic components being produced meet high standards of quality. Visual inspection involves examining electronic components and assemblies closely for any potential defects or inconsistencies affecting their performance or reliability. This type of inspection requires careful observation, attention to detail, and an understanding of the technology involved to identify any irregularities quickly. By using visual inspection methods, manufacturers can detect issues before they become more serious problems down the line.
In-circuit test (ICT) is electronic manufacturing testing that checks for electronic components and circuits’ correct functionality and physical integrity. It is an important quality assurance tool in electronic product development, production, and repair. ICT involves connecting a specialized test system to the electronic circuit board under test and then running tests to detect errors or defects in the parts or their connections on the board. This process helps manufacturers ensure that their products meet design specifications before they are released into the market.
6. Electro-mechanical assembly
Electro-mechanical assembly is a crucial part of electronic manufacturing, given that it combines electronic and mechanical components to create more complex systems. By combining electrical circuits with physical components such as motors, actuators, sensors and other devices, electro-mechanical assemblies can produce highly efficient products used in various industries. However, this process requires a combination of engineering knowledge and skilful craftsmanship to ensure the accuracy of each electronic product. With advances in technology and automation, the electro-mechanical assembly has become increasingly popular for its ability to reduce production time while increasing quality control.
7. Functional Test
A functional test is essential to EMS manufacturing, ensuring the electronic product meets the required specifications and functions correctly. The functional test involves testing each device component to ensure they work perfectly together. That includes testing for compatibility, performance, reliability and safety features. By performing Functional Tests on electronic products during production, manufacturers can save time and money by avoiding costly defects or recalls later.
8. Burn-in Test
Burn-in Test is an EMS manufacturing process used to test the reliability of electronic components. It involves running a device or system under normal operating conditions for a while, usually with simulated environmental conditions such as temperature and humidity. That allows for identifying and correcting any potential defects or problems that may arise during prolonged use before the final product is released. By doing so, the burn-in test helps ensure that electronic products function reliably over their expected lifetime.
9. Wire bonding
Wire bonding is a critical process in EMS manufacturing, allowing for the secure connection of electronic components. That involves joining two pieces with an electrical wire from gold or aluminium. Wire bonding can join multiple electronic components, ensuring they are securely connected and functioning correctly. The most common type of wire bond is a ball bond, where the wire is shaped into a small sphere at each end which makes contact with both electronic components being joined. There are also other types of bonds, such as wedge or stitch bonds, which may be used depending on the project's needs. Wire bonding provides a reliable connection between electronic components while ensuring they remain electrically isolated and operate without interference.
10. Conformal Coating
11. Final Quality Control(FQA)
Final Quality Control (FQA) is an essential step in EMS electronics. It involves inspecting and testing electronic components, assemblies and products to ensure they meet pre-defined quality standards. FQA helps identify potential defects or issues that could affect product performance before reaching the end user. By implementing rigorous FQA procedures, electronic manufacturers can guarantee high levels of quality assurance throughout their production process and reduce costly recalls due to faulty parts or products.
12. Custom Packaging
Custom packaging in EMS electronics is the process of designing and fabricating a unique package that meets the needs of a specific electronic product. This type of packaging is essential for protecting electronic components from environmental hazards such as dust, moisture, vibration, shock, and temperature extremes. Custom packaging also helps reduce costs by providing an efficient way to store and transport electronic products safely. Additionally, custom packaging can help improve product performance and reliability by reducing the risk of damage during handling or shipping. Undoubtedly, manufacturers can ensure their electronic products are correctly packaged while saving time and money on production costs by utilizing custom design techniques.
Why Do We Need an Electronic Manufacturing Service ( EMS) Provider?
Initially, all the EMS electronics is operated by in-house assembly. But it would be easy to face a problem that when the company’s electronic products demand suddenly boom in the market, it is hard for a company to find enough workforce to finish the complete production mission to meet the market need. Therefore, in the 1970s, some companies were established, primarily providing electronic product manufacturing services for small companies with electronic product manufacturing demand but lacking plant or human resources.
EMS enterprises can be vast companies, so they can compete with the most prominent companies worldwide to win those famous brands’ manufacturing orders, such as Cisco, Microsft, iPhone etc. But most EMS companies are smaller companies like Viasion, and we produce small to medium-volume electronic devices for our customers.
How to Select An Electronic Manufacturing Service Provider?
According to Viasion’s experience, regarding selecting an electronic manufacturing service provider, we should consider the following aspects to get the best electronics manufacturing companies. In this article, we’ll talk about what an OEM is and how it can help you when you need help with your product range or promote your services online. We’ll also talk about what kinds of ODMs can help you with your business.

Advantages of an OEM Manufacturing Service
If you have an idea for a product but don't have the time to manufacture it, you should consider using an OEM manufacturing service. These firms have the necessary expertise to produce products for major brands and can manufacture components or devices at much lower prices than traditional manufacturers. They can also meet all the requirements and conditions of delivery and management.
Here are some reasons why an OEM might be a better option.
Nowadays, a brand computer may purchase a computer from one company, print their brand, and sell to the market. While most OEMs sell business-to-business (B2B) products, a VAR(value-added reseller) is a third party that customizes and sells a product to a customer. An OEM generally sells on a business-to-business model, while a VAR sells directly to consumers.
Regarding the design of products, those familiar with the electronic industry share their thought, "ODMs carry out the design by themselves while a brand company is responsible for the design of OEM products, right?" Yes, you got the point. As a result, OEM products are more personalized and feature a broader range of customization. However, OEM manufacturing is resource-intensive. Designers invest millions of dollars in research and development, and they would use the law to protect their design property.
The cost of OEM manufacturing is a significant part of the overall process. Therefore, an OEM may be better for complex products or low volume. An EMS, on the other hand, may be better suited to low-volume, specialized, or niche products. As an OEM, you must find the right EMS provider that fits your product range and business model.
What is ODM?
ODM manufacturing is a type of outsourced manufacturing
Outsourced manufacturing services are available for a variety of purposes. Whether creating a new product or upgrading an existing one, ODMs can help. ODMs are often more efficient than traditional manufacturers and have more control over their products’ design and production processes. In addition, they can upgrade their efficiency through automation and specially designed manufacturing software. You may wonder, “Are ODMs also able to sell products under their own brand?” They can do that in many cases. As a result, this option is ideal for those looking to expand their revenue quickly.
OEM manufacturers build goods based on the specifications and designs of their clients. In contrast, ODMs do not own intellectual property or product designs. Therefore, they offer economies of scale, which means lower unit costs when the same design is built in a high volume. However, ODMs may not have the flexibility to incorporate their clients’ ideas, which can limit their customization options. If this is the case, an OEM may be your best choice.
