The development technology of chip mounters abroad has always been at the forefront, such as Panasonic, Yamaha, and Fuji in Japan, Samsung in South Korea, Siemens in Germany, Universal in the United States, and Philips in the Netherlands, all of which have developed very mature product lines.
D.A. Bodner, M. Damrau, and others from the Georgia Institute of Technology in the United States used the VirtualNC simulation tool, taking the electronic mounting equipment Siemens 80S20 as a prototype, to establish the corresponding digital prototype model, as shown in Figure 12. Based on the three core components of the mounting system, board feeding mechanism, and feeding system, a detailed study of the overall performance was conducted, analyzing the factors affecting mounting speed and how to achieve the minimum mounting cycle time.

Feldmann and Christoph from the University of Erlangen in Germany established a comprehensive multi-body simulation analysis platform based on the idea of multi-body simulation, integrating multi-body dynamics simulation software, finite element analysis software, and control simulation tools, as shown in Figure 13. Using the Siplace F4 chip mounter as a prototype, they established a digital prototype model for the chip mounter, studying the motion characteristics, flexibility, vibration characteristics, and thermal deformation of the mounter. The focus was on introducing methods for establishing linear constraints on flexible bodies and using the "Timing Mechanism" in the ADAMS/ENGINE module to establish a simulation model for the motor-driven toothed belt.
Dr. Masri Ayob from the University of Nottingham in the UK studied the optimization issues of multi-head sequential chip mounters from the aspects of improving the pick-and-place operation, enhancing motion control, nozzle selection, and feeder assembly.
Chip mounters were one of the key development projects in the category of electronic equipment in China's "Seventh Five-Year Plan", "Eighth Five-Year Plan", "Ninth Five-Year Plan", and "Fifteenth Five-Year Plan".
For more than 20 years, some research institutes, universities, and factories in China have carried out the development of various equipment (referring to screen printing, chip mounting, welding, etc.) in SMT production lines.
Since the introduction of the first color TV production line in China in 1978, the Second Institute of the Ministry of Electronics has begun the research and development of chip mounters. Later, the 56th Institute of the Ministry of Electronics, the 4506 Factory of the Ministry of Electronics, the Second Academy of Aerospace, and the Guangzhou Machine Tool Research Institute and other research institutes have conducted research and development, achieving a large number of scientific research results. Although these research results have not been industrialized, they have accumulated valuable experience for future researchers.
Domestic companies that currently have or have conducted research and development and production of chip mounters include: Yangcheng Technology, Panda Electronics, Fenghua Advanced Technology, Shanghai Modern, Shanghai Microelectronics, and Shenzhen Riton. Yangcheng Technology started from the low-end market of chip mounters, targeting small and medium-sized electronic enterprises and research institutes, independently developed and successfully produced the SMT2505 chip mounter, and cooperated with Xi'an Jiaotong University, Central South University, etc. Based on independently developed products, they conducted systematic research on the performance of chip mounters using digital prototype research, achieving certain results. However, there is still a certain gap compared to foreign models, and due to funding issues, the product has not yet entered the mass production stage. Other research enterprises have also conducted the development of chip mounters, completing their respective research topics and prototypes, achieving certain results. Due to the high technical content of chip mounters, long R&D cycles, and large investments, most small and medium-sized enterprises are still at the prototype stage in their R&D work and cannot apply the products to production lines.
Research work on chip mounters in domestic colleges and universities has also never stopped. For example, Yan Hongchao and Jiang Jianguo from Xi'an University of Electronic Science and Technology used an improved hybrid genetic algorithm to study the optimization of chip mounter assembly processes; Li Lei and Du Chunhua from Xi'an Jiaotong University studied the visual inspection algorithms for chip mounters; Yang Fan from Southwest Jiaotong University researched the positioning motion control of SMT chip mounters; Long Xuming reviewed the visual system of chip mounters; Liu Jinbo from Shandong University studied the motion control system of wedge-shaped chip mounters based on vision; Mo Jinqiu, Cheng Zhiguo, and Pu Xiaofeng from the School of Mechanical and Power Engineering at Shanghai Jiao Tong University studied the control systems of chip mounters; Zeng Youjiao and Jin Ye from the CIM Research Institute studied the mounting optimization issues of chip mounters; Yu Xinrui, Wang Shigang, and Liu Shaojun from the Microelectronics Equipment Research Institute studied the image processing technology issues of chip mounter systems; Tian Fuhou and Li Shaoyuan from the Automation Research Institute conducted optimization of chip mounter feeder distribution and genetic algorithm research; Wang Hongsheng and Shi Tielin from Huazhong University of Science and Technology conducted related research on chip mounters from the perspective of vision and image; South China University of Technology collaborated with Fenghua Advanced Technology to conduct related research from aspects such as visual inspection, image processing, motion control systems, and efficiency optimization.
