immediately, the main forum keynote speech began. First of all, Huang Yong, the technical director of Fanyi, introduced the concept of PCB design, and pointed out that when many novices learn PCB design , they often do not get systematic and processed learning, and they lack learning experience, so that even if they lack learning experience, so that they are not even learning experience. In the face of a slightly complex and slightly difficult PCB design, it will seem unable to start.
and the reason why there is a "design difficulty" situation is mainly caused by unclear design ideas, not clear about the above process, and lack of modular thinking at the same time. Especially in the process of high -speed and high -level PCB design, there are many layout of wiring pain points. Therefore, when analyzing circuits and design circuits, it is necessary to quickly distinguish what module circuits, and what are the main points of the design of each module circuit. Huang Yong carried out the project "actual combat" on the spot. It actually demonstrated the circuit diagram and analyzed how to apply modular thinking to achieve efficient layout. Finally, the four main points of improving PCB design efficiency were summarized. Complete the project, follow the complete and mature design process and design specifications, and be familiar with the PCB process technology.

for PCB design, Huaqiu Electronic Software Division Senior Engineer Tao Haifeng continued to explain how to ensure the "manufacturing" of the electronic circuit in the second speech. (Design for Manufacture, DFM) is the manufacturing of the product from the design to improve the product's direct and reliability, making it easier for products to manufacture costs. Specifically, manufacturing design mainly includes three aspects: PCB board can be manufactured, PCBA installed design, and low manufacturing cost design. However, enterprises are now checked by manual inspection list one by one, which is very low and easy to make errors.So that some companies skip this item directly and do not conduct process inspections. Based on this, Huaqiu has developed Huaqiu DFM software -a software specifically for PCB design process inspection.

Tao Haifeng and Huang Yong demonstrated the "Huaqiu DFM" function -mainly include PCB nude analysis, PCBA assembly analysis, optimization direction recommendation, price appraisal assessment , Plum order, impedance computing and other tools, combined with the content of the speech to perform practical operations, and jointly optimized PCB design cases.
event in the afternoon, from PCB design to manufacturing. Hu Qinghan, technical director of Altium Designer, gave a speech around the theme of "PCB Design and Supply Chain and Made in Moon".
Based on the current situation of the electronics industry -electronic design, manufacturing, and device supply chain are still isolated. Compatible, and then rely on the ancient Gerber data format that was born 40 years ago to exchange design intentions and manufacturing information. At the same time, the lack of support for the latest supply chain information in the design will slow down the research and development process of the entire new product, leading to the development process of the entire new product, leading to the development process of the entire new product, which leads to the development process of the entire new product, which leads to the development process of the entire new product. Design engineers and their manufacturers must pay expensive rework costs. For the above pain points in
, Hu Qinghan pointed out that the electronic industry needs to change urgently. It is recommended to use design tools to connect design, manufacturing and supply chain data and professionals to achieve modernization and acceleration of prototype manufacturing processes to ensure manufacturing. Digipcba is such a cloud electronic product design platform that can combine PCB design, MCAD, data management and teamwork.
Hu Qinghan demonstrated the use of DIGIPCBA on the spot. Digipcba's Active ManuoFacturing of PCB quotation, manufacturing process inspection, and one -key ordering. View PCB's boarding costs and delivery dating at any time in the AD21 design environment. At the same time, the Active Manufacturn also has a DFM rules check function, which can greatly avoid the completion of the PCB design before discovering that the manufacturing process of board factory suppliers is not suitable question.
, in addition, the DIGIPCBA design collaborative platform allows users to quickly share and collaborate the latest design at any time. The platform also widely supports multiple MCAD software platforms. Machinery engineers and PCB designers cooperate to design to build the most compact or reliable layout. At the same time, at the same time Avoid a series of iterative rework, solve the problems of back and forth errors and repair problems, and improve efficiency.

impedance design is a skill that must be high -speed PCB design and high -speed links. Focusing on the manufacturing design, Huang Yong continued to target this big pain point in PCB design -stack layer and impedance design. Explanated in detail. Discover matching is very important in high -frequency design. Whether impedance matching or not is related to the quality of the signal. The purpose of impedance matching is that all high -frequency microwave signals on the transmission line can reach the load point, and there will be no signal reflection back source point. Therefore, in the PCB board with high -frequency signal transmission, the control of feature impedance is particularly important. However, it is really necessary to achieve the expected characteristic impedance or actual control within the scope of the expected characteristic impedance value. Only through the management and control of the PCB production processing process can be achieved.
specifically from the perspective of manufacturing, factors such as line width, line distance, copper thickness, medium thickness, medium constant, and welding thickness will affect impedance. So how to avoid pit in the design? Huang Yong shared the basic principles of 12 stack layers, and analyzed the 6 -layer board and 8 -layer plate stacks respectively. The most commonly used impedance computing tools for the PCB industry: The Si9000 Field Solver provided by Polar Company, and shared it. 5 commonly used impedance models. In the end, Huang Yong explained how to calculate the impedance. The audience at the scene said that the dry goods were full and the harvest was quite abundant.

Forum continues to deepen the design of PCB. Zhou Wei, a senior manager of Huaqiu Electronic PCB Engineering Department, conducted PCB manufacturing design and case analysis.Statistics show that in the main production chain, although the cost of design and development and design of the product accounts for only 8%of the total cost, it determines 80%of the total cost. In view of the important role of the product design phase on the quality and cost of the final product, Zhou Wei specifically pointed out that the core value of the Ministry of Engineering is that based on the requirements of the development and design of all engineers, how to identify the requirements and optimize their own design to make production smoother. In order to better play the role of the bridge, Zhou Wei immediately entered the cases of various modules, and shared 6 PCB hole grooves related cases to share case sharing of various modules. As the focus of the focus, a total of 10 PCB line design cases have been prepared to share in detail how to optimize. In addition, one character design case, 2 appearance design cases, and a SET communion design cases are troubled by the back -end production. For common problems, a solution is proposed to help the entire process increase the cost and reduce costs.

Finally, for the downstream manufacturing end, Changsha Huaqiu Deputy General Manager Zhu Cai Haofa analyzed high reliability electronic installation technology and case analysis, combined with PCBA actual production, to SMT storage storage storage for SMT storage storage storage storage Management, SMT preparation layout, SMT production process, DIP production process, TEST process, coating process and other PCBA processes have been introduced.
In PCBA processing, wave welding and backwing welding are two important processes. The result of welding determines the quality of PCBA processing products. In the analysis of welding reliability, Zhu colorful hair details the importance of timely management at key quality control points and its impact on PCBA reliability. Among them, 20%of products will have problems due to the inadequate control of the temperature during the return welding; almost 70%of the welding defects are caused by poor printing of tin paste. The tin paste printing process is related to the success or failure of SMT assembly quality. Among them, the design and manufacturing of Steel mesh is a key factor in the quality of tin paste printing. The design can be appropriately obtained by the results of the tiny paste, otherwise it will lead to process quality Unstable and defects are difficult to control.
