When working with electronic circuits, you often have to deal with temperature-sensitive elements. Overheating them leads to failure of the part. In this case, it is necessary to make a replacement of such an element. The problem is that an error during installation is often only detected during the commissioning process. Also, sometimes the question arises of how to carefully remove the part from the board without damaging it. In this case, soldering stations come to the rescue, which include a soldering dryer. Using the air flow to gently heat the part provides additional options for mounting/dismantling electronic components.
The peculiarity of such stations is that you can adjust the temperature and air flow. By manipulating these two parameters, you can easily unsolder, say, a microcircuit, and not damage it. The soldering iron uses hot air as a working fluid. You need to work with it in a well-ventilated area. With it, you can achieve heating of the tips of the legs of the microcircuit to such a boundary temperature that with a little effort it can be easily removed from the board.
Unlike traditional methods, the blow dryer heatsnot a local point on the board, from which the rest of the heating actually occurs, but the entire required area. Adjustable temperature and air flow allow you to choose the most optimal mode for operation. The convenience of this method has long been appreciated by many radio amateurs.
It's also easy to make a homemade blow dryer using scrap materials. It is possible that they are available in your home laboratory. You can use, for example, some parts from old dental equipment. The product must consist of a heating element, a compressor or fan, an adjustable power supply and a housing. The heating element is wound on a ceramic base and mounted in the housing. Do not forget about safety - the coil will be energized. A tube from the compressor is attached to the body. Ground metal parts of the product. You have a homemade blow dryer that you can use in your home lab.
Turn on the compressor and check the airflow at the outlet of the appliance and check for air leaks. It remains to check the operation of the heating element. First, check the integrity of the entire electrical circuit using an ohmmeter. If everything is fine, then connect it to the power supply and start gradually increasing the voltage. The spiral will begin to heat up. Turn on the compressor and use the high temperature sensor to check the outlet temperature of the homemade appliance. If everything is assembled correctly, then you can get a streamair heated to 300 degrees Celsius. Such a device is quite suitable for working with electronic circuits.
Modern soldering station with hair dryer is designed for a wide range of tasks. The outlet temperature is controlled automatically. It is equipped with various nozzles, which makes it easier to work with diagrams.
