Is it better to use air blower or air pump hot air gun for mobile phone?
Blower type hot-air gun for repairing mobile phone. Compared to the popular hot air grab, the air pump hot air gun will be much simpler. Air pump type air gun has small nozzle and is suitable for single welding. Hot wire general use Ni Cr alloy, but also automatic air cooling function, and temperature control precision, suitable for novice operation. For some simple appliances, the air pump is enough for our needs.Hot air gun is mainly through the resistance heating, blow out hot air on the electronic components for welding, the temperature can be adjusted. Air pump hot air machine boot temperature is faster, more popular than the general, and the temperature will not rise in a straight line, but also with voltage, current and other indicator plate, the internal resistance components can also be replaced.Matters needing attention1, please do not use hot air gun with chemical (plastic) scraper.2. Remove the dry paint of the nozzle or scraper after use so as not to catch fire.3. Please use it in a well ventilated place, because the residue removed from the paint of the lead product is toxic.4 do not use hot air guns as hair dryers.5, do not direct the hot air to people or animals.6, when the hot air gun is used or just after use, do not touch the nozzle. The handle of the hot air gun must be kept dry, clean and far away from oil or gas.7, hot air gun to completely cool before storage.Hot air gun is one of the most widely used tools in mobile phone maintenance, and the process requirements are also high. Hot air guns are used to remove or install small components into large areas of integrated circuits. On different occasions, the hot air temperature and the air gun and other special requirements, the temperature is too low will cause the element weld, the temperature is too high will the worst element and circuit board. The air volume is too small, and the choice of hot air gun is also important. Do not choose low grade hot air gun because of the price problem.
In fact, repair the phone, buy a fan type hot air gun can be!
Classification of hot air grab:1, ordinary typeThe hot air gun is mainly temperature instability, fluctuated, cool instability. The scale of the wind gun is only adjusted to its power size, so the temperature is very slow when it is turned on for several minutes, and then the temperature rises linearly, and it will burn out if you don't pay attention. Such as public square, CPU, circuit board and so on. Although it also has temperature detection, it seems to be used only to protect the temperature, but not to adjust the temperature. I suggest that you do not often lose money in order to save money.2, standard typeThe hot wall of the real scale is used to adjust the temperature, heating up fast startup, tens of seconds to reach, and the temperature will not rise, in the range of similar adjustment, the air volume is relatively stable, suitable for mobile phone repair, I use the air gun is very good, such as the 3508 CPU not in more than 90% burn.3, several sub temperature displayThe performance of second, with basically the same, is a digital temperature display, some is very accurate. However, some display temperature is not allowed, it is prone to sleep. In addition, according to manufacturers and production sooner or later, long ago may not be practical.Add a point, digital thermometer measured, the actual use temperature is: (small head wind mouth) at the tuyere 350-400 degrees, a centimeter of about 300-350 degrees, 2 cm 260-300 degrees. A network of thermometers with digital thermometers can be tested.At the same time, some of the machines have power or other voltage and current indicating dials. Some parts can be replaced.If you're using a hot air gun without digital temperature, you can blow a piece of paper at 3 centimeters with the wind gun to estimate that if the paper doesn't get dark very quickly, it will be yellow as soon as possible.
