Today we will have a look into Hot Air Gun which is specially used for soldering the electronic parts. Surface Mount Devices ( SMD) are group of electronic parts which are very small to handle & solder. Most of them are difficult to solder by hand with solder gun but with the help of this Hot Air Gun, it becomes very easy to handle these SMDs.

In the first part of series of articles on Hot Air Gun, we will see what exactly consists the Hot Air Gun and how it is made.
