When working with electronic circuits, one often has to deal with temperature sensitive elements. Their overheating leads to the failure of the parts. In this case, it is necessary to make a replacement for such an element. The problem is that the installation error is often detected only during the setup process. Also sometimes the question arises as to how accurately to drop the part from the board, without damaging it. To help in this case, soldering stations come with a soldering dryer. The use of air flow for accurate heating of the part provides additional opportunities in the installation / dismantling of electronic components.
The peculiarity of such stations is that it is possible to regulate the temperature and air flow. Manipulating these two parameters, you can easily drop out, say, a chip, and do not damage it. Solder dryer uses hot air as a working fluid. Work with him in a well-ventilated room. With its help it is possible to achieve heating of the tips of the legs of the chip to such a boundary temperature that, with a small effort, it can be easily removed from the board.
Unlike traditional methods, the soldering dryer heats up not the local point on the board, which actually causes the rest of the heating, but all the necessary space. Adjustable temperature and air flow allow you to choose the most optimal for operation mode. The convenience of this method has long been appreciated by many radio amateurs.
Also, it's 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 a fan, a regulated 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 under tension. The tube is connected to the body from the compressor. Ground the metal parts of the product. You've got a homemade soldering hair dryer that you can use in your home lab.
Turn on the compressor and check the airflow at the outlet of the device, as well as the presence of its leaks. It remains to verify the operation of the heating element. First, we check the integrity of the entire electrical circuit using an ohmmeter. If everything is normal, then connect it to the power supply and start to gradually increase the voltage. The spiral will begin to heat up. Turn on the compressor and check the temperature at the output of the homemade device with a high temperature sensor. If everything is assembled correctly, you can get a stream of air heated up to 300 degrees Celsius. Such a device is quite suitable for working with electronic circuits.
A modern soldering station with a hair dryer is designed for a wide range of tasks. Control over the temperature at the output is automatic. It is equipped with various nozzles, which makes it easier to work with circuits.
