For electronics hobbyists and DIY enthusiasts, a hot air gun is definitely a must. It is an important tool used most especially in surface-mount technology (SMT), a method of soldering components to a printed circuit board. Since the components are smaller than usual and their pins are hidden, it is difficult to use a soldering iron.
The hot air gun is identical to a soldering iron as it heats up the soldering lead to secure the component on the board. However, it does not require direct contact unlike the soldering iron does.
Hot air guns are usually expensive, depending on the brand and where you buy it. However, if you have an old soldering iron lying around, you can make your very own hot air gun! In this video, it will be demonstrated how you can transform a soldering iron into a hot air gun using simple tools and techniques.
