一、概述随着电子工业和计算技术事业的飞速发展,特别是印制电路板的广泛应用,对电子部件及其焊接装配的要求日益严格,不但要提高生产率,尤其要提高可靠性。一台普通大型快速电子计算机,目前仅插件就有1000～2000个,每个插件上的焊点少则几十个,多则近千个,焊接工作量十分繁重,而且只要出现一个虚焊点,就会直接影响电子计算机的运行。因此研究焊接新工艺,研制新设备,实现组装机械化和自动化,就日益成为迫切需要解决的问
I. Overview With the rapid development of the electronics industry and computing technology, especially the widespread use of printed circuit boards, the requirements for electronic components and their welding assembly are becoming more and more stringent. Not only productivity but also reliability must be improved. An ordinary large-scale fast computer, currently only plug-in there are 1000 ~ 2000, each plug on the solder joints as few as dozens, as many as nearly a thousand, the welding workload is very heavy, and as long as there is a virtual solder joints , It will directly affect the operation of electronic computers. Therefore, it is an increasingly urgent problem to study new welding technology, develop new equipment, and realize mechanization and automation of assembly
