日本神奈川大学的研究人员利用超声波振动,开发了接合异种金属的“超声波复合振动接合技术”。通常,不使用软钎料(焊锡),而用传统的接合方法来接合铜与铝及铝与铁之类的异种金属是困难的,采用超声波则可实现这类异种金属之间的接合。该技术是固定将要接合的一侧材料,使另一侧材
Researchers at Japan’s Kanagawa University used ultrasonic vibrations to develop “ultrasonic hybrid vibration bonding technology” to join dissimilar metals. In general, solder (soldering) is not used, and it is difficult to join copper and aluminum and dissimilar metals such as aluminum and iron by a conventional bonding method. Ultrasound can achieve bonding between dissimilar metals. The technique is to fix the material to be joined on the side so that the other side material
