How To Use Hot Air Gun For Soldering

Using this method a hot air gun is then used to blow heated air onto the component in order to disconnect the connection.

How to use hot air gun for soldering. Then fire the heat gun onto the solder paste holding the component with tweezers or another tool that wont catch fire until it becomes shiny. Heat-shrinking plastic film - 200 to 300C. When you have a chipset with many legs or when you have a tight working space you can use solder paste and save your time and effort.

Bending plastic pipes - 200 to 300C. Lets get it started. As the paint begins to bubble under the heat move the gun and strip the paint with a scraper.

The paint bubbles and blisters as the moisture and air trapped under the paint expand and force the paint to bubble. 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. Once in place solder the opposite corner again double check alignment is all OK and if so use the drag solder method.

The hot air blow is carried out for about 15 to 20 seconds to complete the de-soldering process. You can simultaneously resolder many different components. While this process isnt exactly surgical it will save you a great deal of time as well as existing solder and parts that otherwise would have been discarded along with the circuit board.

When passing through the reflow oven for the first time gravity holds the components in placeBefore placing the mask board on the conveyor belt the mask should be non-sticky. Theyre too hot heavy and unwieldy for micro-electronics use. Welcome to my Crazy Think channelThis channel includes of guiding videos.

Keep in mind that hot-air is well hot. All you need to do is applying hot air to the solder paste. It doesnt hurt to understand reflow solder profiles.
