Release Date:2016-08-16

method:
Firstly, connect the power and turn on the switch;
Secondly, adjust the wind speed and temperature;
Thirdly, use a hot air gun to heat the chip three centimeters thick above it. After the tin melts, use tweezers to pick up the chip. The heating time should not be too long
Fourthly, turn off the power switch and wait until the hot air gun no longer sprays outwards. Then unplug the power.
Even if you master the correct method, you should still pay attention to the following points when using a hot air gun:
1. Ensure that the hot air gun is properly grounded to reduce the impact of static electricity
2. Ensure that there are no metal objects in the front section of the electric air gun to prevent damage to the heating element and prevent electric shock to the human body
3. Ensure that the hot air gun is not powered off before spraying air
4. Use appropriate temperature
5. Do not place the handle on your nails to avoid problems
