Could you please provide a detailed introduction to the technological progress the company has made in recent years? How does the company view the order cancellations by TSMC's customers?

Changdian Technology: Dear investors, hello. The "Key Technology and Complete Process of High-Density and High-Reliability Electronic Packaging" project in which the company participated won the "First Prize of National Science and Technology Progress in 2020". At the same time, Changdian Technology has developed some popular packaging types that are rapidly developing in automotive electronics and big data storage, actively building a new business platform for design services, and continuously strengthening Changdian Technology's core competitiveness and implementing it at the factory end. For example, in the field of 5G communications, 5G-related millimeter-wave RF products and test solutions as well as millimeter-wave AiP and RFFE modules have been developed; in terms of high-performance computing applications, we have been working with different wafer fabs on advanced process silicon nodes, and will launch the XDFOI? Full range of products in 2021 to provide global customers with industry-leading ultra-high-density heterogeneous integration solutions. In the automotive market, we have been working closely with major customers to develop packaging technologies related to electric vehicles and autonomous driving with higher reliability standards. For example, the Radar system solution based on eWLB, the SOIC solution for sensors used in vehicle safety systems (airbags) and driving stability detection systems, and the LGA solution for LiDAR. In order to meet the application requirements of advanced silicon nodes, we have developed materials and processes for large-size FCBGA applications. In the storage market, the company has developed 16-layer NAND flash stacking, 35um ultra-thin chip process capabilities, hybrid special-shaped stacking, etc., all of which are in the leading position in the domestic industry. The company actively pays attention to changes in the industry. The current domestic demand for consumer and communication products has declined to a certain extent, which has brought certain pressure on the growth of domestic customer revenue. The company will strive to give full play to the advantages of domestic and international dual circulation and multi-application layout, flexibly adjust the order structure and production capacity layout, and meet the changing needs of different customers. Thank you for your attention and support.
