一、前言在以晶体管为中心的分立元件的电子设备和电子系统中要用大量的接插件来实现各部分的电连接。随着大规格集成电路的集成度的提高以及印刷电路板上的组装密度的提高,对接插件也提出了小型化、高密度和高可靠性的要求。所以,连接技术就更加显示了它的重要 I. Introduction In the transistor-centric discrete components of electronic equipment and electronic systems to use a large number of connectors to achieve the various parts of the electrical connection. As the integration of large format integrated circuits increases and the assembly density on printed circuit boards increases, the mating connectors also demand miniaturization, high density and high reliability. Therefore, the connection technology more shows its importance
