However, the development of the electronics manufacturing industry has also brought many challenges, such as environmental protection issues, technological innovation pressure, supply chain management optimization, etc., which have prompted the industry to continuously explore greener, more efficient, and smarter production models. Let’s take a look at what electronics manufacturing issues will be covered in this guide

1. What are electronic manufacturing services?

Electronic Manufacturing Services (EMS) is an industry term that covers a wide range of activities. It not only represents a global production model, but also refers to those companies that focus on providing a full range of electronic products to original equipment manufacturers (OEMs) and brand owners. Specialized subcontractors or companies that manufacture solutions. In this field, electronic manufacturing service providers are responsible for a series of complex processes from product design, prototyping, material procurement, production assembly, quality assurance to logistics distribution and after-sales support, effectively acting as the production engine behind the brand. In addition, “contract manufacturing” (CM) is another concept often used in the electronic manufacturing service industry. The two are used interchangeably to a large extent, both emphasizing the large-scale production of electronic products through outsourcing. Electronic manufacturing service providers use their economies of scale, professional technology, supply chain management advantages, and strict cost control capabilities to help customers reduce operating costs, shorten time to market, and improve product quality.

2. Basic steps of electronic manufacturing

DFM inspection and improvement

DFM inspection is an integral part of the electronic manufacturing process. During the electronic manufacturing process, DFM inspection will conduct a comprehensive and detailed evaluation of the products in the design stage to ensure that the design solution is easy to manufacture, assemble and inspect. XingHongTai’s team of professional engineers will review the product’s processability, ease of assembly, and quality control points, starting from aspects such as material compatibility and process routes, to discover from the source whether there is a better way to design the product.
Based on the results of the DFM inspection, the XingHongTai design team will use advanced simulation technology to simulate the production process, improve the structural layout, and reduce the number or complexity of unnecessary parts; at the same time, it will focus on standardization and modular design of parts to improve commonality and interchangeability. , reduce production costs and inventory pressure, speed up production, and improve overall efficiency.

Material procurement and inspection

XingHongTai Company has a professional electronic component database system, which contains nearly 1,000 leading electronic component suppliers in China, and has established a long-term cooperation system with us to facilitate us to quickly select cost-effective products based on design plans. , high-quality, high-functional electronic components. We will also strictly conduct incoming material testing to ensure that each electronic component can meet production requirements and comply with Rosh environmental standards and product certifications (UL, CE, etc.) in the electronics manufacturing industry.

PCB mounting process

In the electronics manufacturing industry, there are various PCB mounting processes. At XingHongTai, we will combine various processes to meet your needs for different products of various difficulties.
1.SMT (Surface Mount Technology): Fully automatic surface mount technology (SMT) is used to accurately mount resistors, capacitors, IC chips and other components at designated positions on the PCB to achieve the initial construction of the circuit.
2.DIP (Dual In-line Package): For large or special components that are not suitable for the SMT process, such as integrated circuits, power devices, etc., they are inserted into the corresponding holes on the PCB board through a through-hole plug-in (DIP) to complete the component installation.
3.Reflow soldering: After the SMT patch is completed, the reflow soldering process is used to ensure stable soldering quality and reduce defects caused by manual operations.
4.Wave soldering: In the DIP process, we will use wave soldering. Although it is slightly inferior to SMT in terms of space utilization and production speed, the DIP process also has its unique value. For example, components packaged in DIP have higher mechanical strength and good seismic resistance, making them suitable for scenarios that require higher stability.

Testing and assembly

Functional testing is an important part of product quality control. Engineers can verify the functionality of each component on the circuit board, the correctness of electrical connections and the welding quality through some tests, thereby troubleshooting potential faults and ensuring that the product meets design specifications and performance standards. The debugging phase focuses more on in-depth optimization and fine-tuning of the overall system functions to make the product more stable and efficient in the actual operating environment. Assembly is the process of seamlessly integrating rigorously tested circuit boards with other mechanical components, housings, displays, etc. XingHongTai is also constantly exploring new assembly technologies, such as modular design, flexible production lines, etc., to adapt to rapidly changing market demands and the trend of personalized customization.

1.ICT testing (In-Circuit Testing): Online testing, which uses special equipment to detect each component on the PCBA and its interconnections to ensure that all electronic components are installed correctly and form effective electrical connections.
2.FCT test (Functional Circuit Test): Functional circuit test, which simulates the actual use environment and operating mode to comprehensively verify the functions of the entire circuit board and check whether the product can execute various instructions according to the design requirements.
3.AOI test (Automated Optical Inspection): Automatic optical inspection, using high-precision cameras to capture PCBA surface images, and using algorithms to identify whether solder joints and components are missing, offset or poorly welded.
4.Burn-In Test: The PCBA is placed under specific conditions (such as high temperature, high pressure, etc.) for a long time to test the durability and potential failures of the product.
5.X-Ray inspection: For packaged components such as BGA and CSP, X-ray perspective technology is used to check the quality of internal solder joints to ensure that there are no voids, disconnections and other hidden dangers in hidden solder joints.
After passing a series of tests, we will assemble and integrate the PCB motherboard with other structural parts such as casing, display screen, buttons, etc., and gradually form a prototype of a fully functional electronic device. Finally, comprehensive functionality, stability and environmental adaptability tests are conducted to ensure that the product meets the preset standards and passes various certifications.
