电子产品制作及维修中热风焊枪使用技术研究

Study of Electronic Products Making and Using Skills of Hot Air Welding Gun

热风枪是制作及维修现代电子产品的主要工具,操作要求较高。从焊接或拆卸小型电子元件到大规模集成电路必须使用热风枪来完成。操作中要对热风枪的温度、风量加热时间要严格控制,温度过低会是加热时间延长,容易造成元件虚焊、假焊,降低了焊接的机械强度和电接触性;温度过高容易烧坏元件及线路板,造成不必要的损失。风量大了又会吹掉小型元件,为此,正确使用热风枪是制作及维修电子产品关键环节。本文就热风枪使用技术向读者做了详细介绍,供广大读者参考。

Hot air gun is the main tool for making and maintaining modern electric products and it has a higher operation requirement.From the welding or removing of small-type electronic components to large-scale integrated circuit,the hog air gun is necessary.In the operation process,a strict control must be taken for the temperature,air volume and heating time of hot air gun as a over-low temperature will prolong the heating time and cause empty solder and false solder,furthermore,reduce the mechanical strength and electrical contact property of welding.A overhigh temperature will burn out cir gun is the key part of making and maintaining electric products.In this paper,it has introduced tomponent and circuit board and then cause unnecessary losses.If the air volume is too big,it will blow off small-type component,therefore,correct using of hot ahe using skill of hot air gun in detail so that to provide reference for readers.
