这几年,表面安装元件的高功能、小型化急速发展,表面安装技术也正向更高密度安装发展。现在,再流焊有几种加热手段和方法,但必须确切掌握再流焊法的优缺点来进行选择。表面安装元件高密度安装的再流焊方法之一是汽相钎焊。这是使氟系惰性有机溶剂沸腾,利用其饱和蒸汽进行钎焊的方法。由于PLCC式引线弯向内侧的元件不断增加,这种热弥散良好的蒸汽钎焊方法在产业界引人注目。 VPS装置的概要所谓VPS是汽相再流钎焊(VaPor Phase Re-flow Soldering)的缩写,这种装置将氟系惰性
In recent years, surface mount components of high-performance, miniaturization of the rapid development of surface mount technology is also the development of higher density installation. Now, there are several heating reflow soldering methods and methods, but must grasp the advantages and disadvantages of reflow soldering methods to choose from. Surface Mount Components One of the reflow soldering methods for high density mounting is vapor phase brazing. This is a method of boiling a fluorine-based inert organic solvent and brazing it with saturated steam. Due to the ever-increasing number of PLCC-type leads that bend inward, this thermally-diffusible steam-brazing method has gained prominence in the industry. Summary of VPS Device The so-called VPS is an abbreviation of VaPor Phase Re-flow Soldering, which is a fluorine-based inert
