How to use hot air gun for soldering. It doesnt hurt to understand reflow solder profiles. One more benefit of using a hot air rework station is it can be used as a soldering station due to their multipurpose functionality. Bring the Nozzle of Blower close to the Circuit board and wait until the Solder paste melts and fuses with the IC Pins.

Trying to solder with a cheapo hot air gun. Theyre too hot heavy and unwieldy for micro-electronics use. A hot air gun which will melt the solder and enable you to remove the components is great for removing parts from an old circuit board.

Heat guns are best used for fixing broken connections on a populated board or for adding or removing new connections. The following descriptions use that method and focus on a small section of a printed circuit board as shown below. Welding some plastics - 330 to 400C.

Bending plastic pipes - 200 to 300C. I use analog hot air stations because I dont want to turn around and look at the temperature. A heat gun should always be used with care around copper plumbing where solder connectors have been used as the heat can melt the solder and weaken the joints.

Saying the magic spell meltum meltum meltum move the nozzle back and forth until the solder begins to flow the solder should appear shiney and molten. Do not burn the paint. The hot air blow is carried out for about 15 to 20 seconds to complete the de-soldering process.

The top photo shows a board that has been populated and reflow soldered in an oven and the bottom photo shows the bare board. Then carefully removereposition the part you want to rework using tweezers by nudging or grabbing the part. As like soldering process hot air blow is using to de-solder SPNova.
