基于電磁驅(qū)動的倒裝機(jī)鍵合裝置設(shè)計
[Abstract]:The national security has been paid more attention than ever. The chip industry related to information security has been promoted to the national strategic height. It is urgent to increase the localization rate of integrated circuits, and the major trend of the localization of chips has become irreversible. Semiconductor packaging equipment is the basis of the development of integrated circuit industry in China. At present, China's advanced equipment and technology are in a state of backwardness. High-speed, high-precision positioning system is required in semiconductor rear-channel packaging equipment. The bonding device is the key module of the high density reverse loader, which is responsible for picking up and placing the chip by semiconductor equipment, and the chip bonding also needs to achieve soft landing in the process of high speed patch. Reach bonding device can provide "hard and soft" pressure to the chip. The bonding head based on electromagnetic driving principle has good characteristics of high speed and high precision motion control. It is widely used in many kinds of semiconductor packaging equipment such as lead bonding machine, wafer tapping and component detection and so on. In this paper, a new type of bonding device for high density reverse loader is designed based on the high density flip machine developed by the 45 Research Institute of China Electronic Science and Technology Group (Ministry of Science and Technology). The device can realize picking up and placing chip. Flexible pressure control and fast response functions. By using the traditional magnetic circuit method and finite element electromagnetic simulation technology, the electromagnetic field of the bonding device is analyzed in depth. The distribution of magnetic field, the density of air gap and the magnetic saturation are visualized, which provides a theoretical basis for the optimal design of the device. A large amount of heat will be produced in the working process of the electromagnetic mechanism. The three-dimensional temperature field of the device is simulated, the temperature field distribution is given, and the parameterized analysis of the temperature field with different power is carried out. It provides theoretical support for the thermal analysis of the device. This will help our country to master the key technology of the reverse bonding process and shorten the technical gap with foreign equipment. It is of great strategic significance and economic value to improve the market core competitiveness of packaging equipment in China and to promote the rapid development of advanced microelectronic packaging technology in China.
