How to use hot air gun for soldering. As the paint begins to bubble under the heat move the gun and strip the paint with a scraper. I am working with SMD for a while and I suggest you use leaded solder to treat the oxidized solder joints with flux before you get to the hot air stage. Lets get it started.

It is possible to quickly take out a faulty electrical part from the circuit board as well as resolder the particular area in a few minutes. This is also how some people use hot air and solder paste to solder SMDs. Use a fine tip iron solder one pad first on the corner of the part if its not quite right re-heat and shift the part until it is correct.

Non-contact and non-contaminating hot air soldering convection is best suited for ceramic chip resistors and capacitors. One more benefit of using a hot air rework station is it can be used as a soldering station due to their multipurpose functionality. Keep in mind that hot-air is well hot.

How to use dot masks for wave soldering and conformal. Welding some plastics - 330 to 400C. For example heat soak the whole board at 125C for a while before doing the rework.

Heat guns are best used for fixing broken connections on a populated board or for adding or removing new connections. All PCBs should be carefully thermally ramped 2ºC-4ºC per second with a preheating soak prior to soldering or desoldering tasks whether in production prototyping or in rework or repair. Then the hot air gun is used to bring the component leads up to the solder melting pointThe theory is that this allows much shorter spot heating and less damage to adjacent components.

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. A solder gun is a pistol-shaped iron typically running at 100W or more and is completely unsuitable for soldering modern electronic components.
