人们在发展电子设备的组装技术过程中,曾经历了几次重大变革,即所谓接线柱装配技术,插装技术以及发展到今天的面装技术.人们认为面装技术的出现,是对传统组装技术的一种革命性冲击.而面装元件则是这一技术的关键.从20世纪70年代中期起,人们采用无引线或短引线元件,将它们贴在基片(可以是印制线路板,也可以是陶资、玻确或有机材料)上,采用各种不同的方法进行必要的电连接,从而形成功能电路。这就是目前在国内 People in the development of electronic equipment assembly technology, has undergone several major changes, the so-called terminal assembly technology, plug-in technology and the development of today’s surface mount technology.People think that the face-mount technology, the traditional assembly Technology, a revolutionary impact.And the surface mounted components is the key to this technology.From the mid-1970s, people use leadless or short lead components, they are attached to the substrate (which can be a printed circuit board , It can be pottery, glass or organic materials), using a variety of different ways to make the necessary electrical connections, thus forming a functional circuit. This is currently in the country
