For example heat soak the whole board at 125C for a while before doing the rework.

How to use hot air gun for soldering. 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. Welcome to my Crazy Think channelThis channel includes of guiding videos. Hot-air soldering is customarily used with surface-mount devices being attached to printed circuit boards.

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. 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. Theyre too hot heavy and unwieldy for micro-electronics use.

Bending plastic pipes - 200 to 300C. 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. The following descriptions use that method and focus on a small section of a printed circuit board as shown below.

As the paint begins to bubble under the heat move the gun and strip the paint with a scraper. Once in place solder the opposite corner again double check alignment is all OK and if so use the drag solder method. 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.

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. A solder gun is a pistol-shaped iron typically running at 100W or more and is completely unsuitable for soldering modern electronic components. Please Note that If you are soldering LEDs using this method do not blow the hot air directly on the LEDs Instead blow the hot air behind the PCB to heat the pads and the solder paste will fuse together with LED.

This should take no longer than a minute. Heat-shrinking plastic film - 200 to 300C. Then carefully removereposition the part you want to rework using tweezers by nudging or grabbing the part.
