When working with electronic circuits, you often have to deal with temperature-sensitive elements. Their overheating leads to the failure of the part. In this case, it is necessary to replace such an element. The problem is that an installation error is often detected only during setup. Also, sometimes the question arises of how to carefully remove a part from the board without damaging it. In this case, soldering stations come with a soldering hair dryer. The use of an air stream to accurately heat the part provides additional opportunities for mounting / dismounting electronic components.
A feature of such stations is that it is possible to control the temperature and air flow. By manipulating these two parameters, you can easily drop out, say, a microcircuit, and not damage it. The soldering iron uses hot air as a working fluid. You need to work with him in a well-ventilated area. With its help it is possible to achieve heating of the tips of the legs of the microcircuit to such a boundary temperature that with a small effort it can be easily removed from the board.
Unlike traditional methods, a soldering iron does not heat a local point on the board, from which the rest of the heating occurs, but the entire necessary 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 hams.
It is also easy to make a homemade soldering hair dryer using improvised 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 should 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 a housing. Do not forget about safety - the spiral will be energized. A tube from the compressor is connected to the housing. Ground the metal parts of the product. You have a homemade soldering iron that you can use in your home laboratory.
Turn on the compressor and check the air flow at the outlet of the device, as well as its 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 normal, then connect it to the power supply and begin to gradually increase the voltage. The spiral will begin to burn. Turn on the compressor and use a high temperature sensor to check the outlet temperature of the homemade appliance. If everything is assembled correctly, then you can get a stream of air, heated to 300
degrees Celsius. Such a device is quite suitable for working with electronic circuits.
A modern soldering station with a hairdryer is designed for a wide range of tasks. Control over the temperature at the outlet takes place automatically. It is equipped with various nozzles, which facilitates the work with schemes.
