Is it better to use a fan-type hot air gun or an air pump-type hot air gun to repair mobile phones?

Fan-type hot air gun for repairing mobile phones. Compared with the popular hot air gun, the air pump hot air gun is much simpler. Air pump air gun nozzle is small, suitable for single welding. The heating wire is generally made of nickel-chromium alloy, and also has the function of automatic cold air cooling, accurate temperature control and suitable for novice operation. For the maintenance of some simple electrical appliances, the air pump and hot air blower are enough to meet our needs.

Hot air gun is mainly used for welding electronic components with hot air blown by resistance heating, and the temperature can be adjusted. The starting temperature of the air pump hot fan is also faster than that of the general popular fan, and the temperature will not rise linearly. It also has voltage, current and other indicator boards, and internal resistance components can also be replaced.

Matters needing attention

1. Do not use a hot air gun with a chemical (plastic) scraper.

2. Please remove the dry paint from the nozzle or scraper after use to avoid fire.

Please use it in a well-ventilated place, because the residue removed by paint of lead products is toxic.

Don't use the hot air gun as a hair dryer.

5. Don't aim hot air at people or animals.

6. Do not touch the nozzle when the hot air gun is in use or just after use. The handle of hot air gun must be kept dry, clean and away from oil or gas.

7, hot air gun should be completely cooled before storage.

Hot air gun is one of the most widely used tools in mobile phone maintenance, and its technological requirements are also very high. Hot air guns are used to remove or install small components to large integrated circuits. On different occasions, there are special requirements for the temperature and air volume of the hot air gun. Too low temperature will lead to virtual soldering of components, and too high temperature will lead to the worst components and circuit boards. Too much air will blow away small parts, and it is also important to choose a hot air gun. Don't choose a low-grade hot air gun because of the price.
