Correct use of electric soldering iron and hot air cylinder
1. Before the new soldering iron is energized, soak it in pine fragrance.
2. When using an electric soldering iron for the first time, dip a layer of tin on the tip of the soldering iron.
3. Use rosin or non-corrosive flux when soldering.
4. Wipe the tip of the soldering iron with a soaked sponge or a damp cloth.
5. Do not use sandpaper or a file to sharpen the tip of the soldering iron (except when trimming).
6. After soldering, do not wipe off the solder left on the tip of the soldering iron.
7. The shell of the electric soldering iron should be grounded, and the power should be cut off when it is not used for a long time.
8. Always clean the oxide in the shell of the external heating electric soldering iron to prevent the tip of the soldering iron from being stuck in the shell.
How to use the hot air cylinder correctly
1) Correctly adjust the temperature of the hot air cylinder. Such as: blowing welding inline seat requires a temperature between 280 and 300 degrees. If it is high, it will blow the deformed seat, and if it is low, it will not blow down. Blow-soldering soft package IC requires a temperature between 300 and 320. If it is too high, it is easy to blow the IC, but if it is too low, it cannot be blown down, and it is easy to destroy the pads, resulting in irreparable failures.
(2) Correctly adjust its wind speed. For beginners to use the hot air table, the knobs of "temperature" and "air supply volume" should be placed in the middle position.
(3) When using, it should be perpendicular to the IC and 1-2 cm away from the component to move the blowing welding evenly, not to directly touch the component pins, and not too far. Do not remove the IC until the IC is completely loose, otherwise hard removal will damage the pads.
(4) When welding or dismantling components, do not blow hot air continuously for more than 20s at a time, and do not use hot air for more than 3 times in the same position
(5) When finished or not in use, adjust the temperature to the lowest and the wind speed to the highest. This makes it easy to dissipate heat and heat up quickly.
