| With the continuous development of micro-electromechanical systems, electronic components, and medical devices in the direction of miniaturization and high performance, the resistance microwelding (RMW) process of fine and ultra-fine wires is more and more widely used and important. In this paper, from the principle and main process parameters of RMW, the research status of RMW for fine and ultra-fine wires at home and abroad in recent years, relating to the RMW process, bonding mechanism, process numerical simulation, were reviewed. The application of this technology in the field of electronic packaging and medical devices was introduced. Finally, special attention was paid to the future trends and prospects of RMW for fine and ultra-fine wires. The future development direction mainly comprises the development of RMW equipment, the study of the welding mechanism, the weldability of dissimilar materials, the simulation of welding process and the quality monitoring of the welding process. |
