2024 International Brazing, Diffusion Welding and Micro-nano Joints Conference and the 8th China (Hangzhou) Green Joints and Manufacturing 2024 Summit Forum

【Summary Description】 On the morning of October 21, 2024, the 2024 International Brazing, Diffusion Welding and Micro-Nano Connection Conference and the 8th China (Hangzhou) Green Connection and Manufacturing 2024 Summit Forum were successfully opened at the Intercontinental Hotel in Liangzhu, Yuhang District, Hangzhou. Gong Shuili, deputy director of China Welding Society, Zeng Xiaopeng, vice chairman of Zhejiang Science and Technology Association, Professor Li Xiaoyan, executive committee member and chairman of Technical Committee (TMB) of International Welding Society (IIW), and other expert leaders delivered welcome speeches at the opening ceremony. The conference was hosted by the Welding Branch of the Chinese Society of Mechanical Engineering, Hangzhou Huaguang Welding New Materials Co., Ltd., Zhejiang University of Technology, National Key Laboratory of Precision Welding and Connection of Material Structures, State Key Laboratory of New Brazing Materials and Technology, Tsinghua University, Jointly hosted by Beijing University of Technology. In June 2014, the Welding Branch of the Chinese Mechanical Engineering Society successfully held the "International Conference on Brazing and Special Connection Technology" in Beijing. After a lapse of ten years, the Welding Branch held such an international conference again. 02 Conference Invited Report Brazing, diffusion welding and micro-nano connection technology has been playing an important role in aerospace, transportation, new energy, semiconductor, integrated circuit, high-end manufacturing and other fields. This time, experts, scholars, scientific and technological personnel and enterprise representatives from more than ten countries at home and abroad participated in the meeting, To conduct in-depth exchanges on cutting-edge research and future development in related fields, this paper focuses on the opportunities and challenges faced by brazing, diffusion welding and micro-nano connection under the background of "carbon peak and carbon neutral", so as to promote the development of disciplines, personnel training, technological progress and industrial upgrading. Focusing on the directions of "advanced brazing diffusion welding, new technologies and applications of micro-nano connection," this conference arranged a number of academic exchange activities such as conference reports and branch theme reports from October 21 to 23. as the highlight of the meeting, after the conclusion of the opening ceremony, the meeting arranged 7 special invited reports on solder design applied to ceramic composite materials, using electrostatic jet deflection system to improve the printing speed of electrofluid jet printing, the basic principle and solution of hard alloy brazing, the latest progress of surface activated bonding for heterogeneous material bonding, B- class conductive adhesive in advanced electronic packaging technology, dissimilar material brazing and diffusion welding, nano-connection and micro-nano device integration. 03 Summit Forum After the special invitation report of the conference on the afternoon of October 21, Huaguang New Materials held a green connection and manufacturing summit forum with the theme of "artificial intelligence integration and innovation. Artificial intelligence (AI) is an important driving force for the new round of technological revolution and industrial transformation, bringing many new industrial opportunities. Welding and connecting materials and corresponding technologies are also closely related to the development of artificial intelligence. This summit forum specially invited 8 senior experts at home and abroad to focus on the design of artificial intelligence in the Welding materials, the application of welding robots, the innovation of electronic and micro-nano connection materials related to artificial intelligence, and the future technology of brazing and micro-nano connection materials. Exchange and interaction on topics such as industrial direction. 04 Academic Exchange Report From October 22 to 23, the conference will also arrange more than 60 academic exchange reports in the two sub-venues of brazing and diffusion welding and micro-nano connection, among them, brazing and diffusion welding mainly involve multi-main element brazing materials for brazing challenges, wetting and interfacial reaction of high-entropy carbide ceramics, electron beam brazing of different metals using AgCuTi interlayers, brazing of diamond films and copper using AgCu-based brazing materials to manufacture microwave windows, basic principles and applications of diffusion welding and the latest inventions, research progress of ultrasonic-assisted brazing, and multi-energy field hybrid fusion brazing technology for dissimilar metals; the micro-nano connection sub-conference mainly involves discussions on the properties of nano-materials for low-temperature welding, the mechanism of solder joints in electronic packaging structures, 3D integrated high-flux bonding technology of nanoparticles, ultra-fast laser packaging technology of semiconductor materials, IPL welding technology in carbon-neutral electronic packaging, new interconnection materials and technologies for IC packaging, and advanced packaging technology of copper paste technology. The multi-topic academic report will bring more opportunities for in-depth study and exchange for the participants. This conference is of great significance to enhance the international competitiveness, academic influence and innovation guidance of China's brazing, diffusion welding and micro-nano connection technology. By hosting this international conference, Huaguang New Materials strengthens the exchanges between international academia and industry, and further enhances the international influence of Huaguang New Materials. Innovation drives and connects the future. Huaguang New Materials expects to continue to work with experts, scholars and industrial chains at home and abroad to jointly promote technological progress and high-quality development of the industry and help the development of new quality productivity through the platform of Green Connection and Manufacturing Summit Forum.
