Research and Application of Self-propagating Joining Technology in Nanostructured Multilayer Foils

近年来,利用纳米结构多层膜自蔓延反应瞬间放热作为局部热源实现材料连接的方式逐渐受到人们的重视,其具有反应瞬间完成、连接效率高、适用于热敏感材料并且可以避免元器件从高温冷却时产生较大的热应力等特点。介绍了纳米结构多层膜的制备方法及反应机理,并综述和分析了在陶瓷/金属互连、不锈钢器件、非晶材料的连接以及微电子芯片技术方面的应用。

As a local heat source in joining fields, self-propagating reactions in nanostructured multilayer foils have been drawing more and more attention in recent years. It reacts instantaneously, can join the materials in a highefficiency way, therefore, it is very suitable for joining temperature sensitive components and avoids the large thermal stresses that typically develop when components are cooled from elevated processing temperatures. The preparation method of nanostructured multilayer foils and its reaction mechanism are introduced. Furthermore, its application in various materials joining such as ceramics-metal, stainless steels, amorphous materials and microelectronics chip interconnect technology is also analyzed.
