What is the soldering station
Soldering station, unlike a simple soldering, - more sophisticated system. It allows to solder small parts, such for example as SMD-components to control heating of the score is, the programming button. Moreover, due to non-contact soldering system overheating of neighboring elements are excluded.
Soldering station-contact type relates to improved soldering. For example, heating by a heat gun helps craftsmen to repair household appliances and mobile phones. But with the possible assembly and disassembly by IR systems chipset (Even BGA format).
General characteristics and operation of the soldering station
Anatomy of a rework station is simple and maximally meet the necessary conditions: neat, "intelligent" soldering elements. The heart of the device - Power SupplyInside which is a transformer, outputs a voltage two embodiments 12 or 24 volts. Without this element, all the stations of the system would be useless. The transformer is responsible for temperature control. The power supply equipped with temperature control and special start device buttons.
For reference! Some devices are equipped with a special stand, which heats the PCB during the soldering process, which helps to avoid its deformation.
With the help of the control unit can also be realized by storing a function of temperature and the programming buttons. Master "pumped" device, using the processor, through which it is possible to measure the temperature during brazing.
Let us examine the features of the hot air soldering station: the air flow with the help of special helical or ceramic elements (they are just inside tube heat gun) is heated, and then through the special nozzles directed to a point soldering. This system allows you to heat the required surface evenly, eliminating the dot deformation.

"The temperature that can provide modern dryers soldering, including raised their hands, ranging from 100 to 800 ° C. Moreover, these indicators can be set by the operator. "
In a special infrared heater can act as another additional element. The principle of it is similar to the work of a heat gun, it heats the interface is not the place, but a certain area. However, unlike hot air gun, there is no flow of hot air. Professional soldering station can be equipped with special related tools, Desoldering tweezers and vacuum.
Variations in design soldering stations
There are both simple soldering station equipped with a soldering iron classic familiar to us, and the more advanced. Moreover, variations of combinations of components and systems can be a great variety. Can be easily combined in one station soldering iron pin and hair dryer, a vacuum or Tweezers and Desoldering. For convenience, we give a table of the main types of soldering stations.
| Contact PS- an ordinary having soldering direct contact with the surface, a soldering iron, equipped with an electronic control and regulation of temperature. | Contactless PS - to work through a control unit and a special system controls. | |||
| lead | Lead-free Requiring higher melting temperature. | Hot Air Provide efficient soldering in difficult areas with bullet warming multiple surfaces. It allows soldering of any kind as to lead, and without it. | infrared Here there is a heating element in the form of infrared emitter made of ceramic or quartz. | combined Combines in its design several types of equipment: a hair dryer or a classic soldering, or, as we have said, the IR heater and let Desoldering, soldering iron and a hair dryer. |
For temperature stabilization mechanism and operating principle of control units soldering stations can be divided also in analog and digital. In the first case the heating element is switched on until soldering has warmed to the desired temperature, the closest analogy - a conventional heating iron. But the second type of solder has a complex temperature monitoring and control system. Here placed PID-controller, who reports to the microcontroller program. Such temperature stabilization method is much more effective than analog. Another classification allows to share all of the SS on the assembly and dismantling. First performed soldering devices, however, have not Desoldering and other elements that allow for cleaning and replacement parts.
Such soldering system provided with a special capacity for removal of solder, which in turn is sucked special nozzle, equipped with a compressor.
Note! There are combined station allows for both installation and dismantling. They are equipped with two types of soldering irons with different power.
How to make your own hands Rework Station
Buy soldering station with a hairdryer not everyone can afford, although IR stations are still a lot of money, so the easiest way - to collect her own hands. However, it should be remembered that such air soldering stations have certain disadvantages:
- Air flow can accidentally blow away the little details.
- Surface uniformly warmed.
- Different cases require additional nozzle.
Soldering hair with your hands: the universal scheme
Thermo - special device that heats the soldering hot air flow.
The easiest way to assemble the device with a hair dryer on a ventilator, and as a heater used spiral.
If you buy a mechanical heater, it is quite expensive. And when sharp temperature changes can simple crack. Not everyone can construct their own compressor. As the ash can be used a conventional compact fan. Suitable cooler from a home PC. Looking for a device of such a device will examine the scheme soldering station with their own hands.
The fan is located near a heat gun. To it accurately attach the tube to supply hot air. At the end of the cooler grind a hole under the nozzle. On the opposite side of the cooler should be closed to ensure the necessary traction.
Now it was the turn of the heating element assembly. For this it is necessary to wind the coil on the nichrome wire heater base. Moreover, the coils must not touch each other. The coils are wound in view of the fact that the resistance should be 70-90 ohms. The base is selected from the poor thermal conductivity and good resistance to high temperatures.

"Some details can be gathered from a conventional dryer. In particular, as a basis for a spiral with low thermal conductivity is suitable mica plate. "
Getting to search for the nozzle parts. It is best for this suitable pipe made of ceramics or porcelain. Leave a small gap between the walls of the nozzle and spiral. Above the surface winding insulating materials. It is possible to use asbestos layer, fiberglass, etc. This will increase the high efficiency of the dryer and allow him to take his hands without getting burned. Fasten the heating element so that air is supplied into the tube, and the heater was located exactly in the middle inside the nozzle.
soldering station control system
To build the control system of a self-made soldering station type hair dryer with their hands in it is necessary to place two rheostat, one adjusts the input stream, the other - the power of the heating element. And here switch usually done for one of the heater, as well as for the supercharger.
It is very important to connect the wires so that they are aligned with a rheostat.
Then attach heat gun so as to correspond to the desired wire rheostats and switch.
Assembly and setting work a soldering station
Power soldering station, as we have already noted above, is typically in the range of 24 to 40 watts. However, if you plan to solder the power bus Guides, The capacity of the device must be increased from 40 to 80 watts.
For more information about how to solder a hairdryer from the soldering station, see this video.
Infrared Soldering Station with his hands
Infrared Soldering Station - the tool that is most easily done by hand. The price for this type of soldering stations simply exorbitant. Buy something simpler - not an option, as will still be limited functionality.
That is why we tell you step by step how to build with their own hands infrared soldering. Let us examine the SS assembly steps for soldering circuit boards of 250 × 250 mm. Our soldering station is suitable for use with TV cards, graphics cards for PCs and tablets.
Making the housing and the heating elements
For the basics of homemade infrared soldering station, collected his own hands, you can take the door on the mezzanine or plywood 10-12 mm, bolted to her feet. At this stage it is important to roughly estimate the arrangement of the heaters based on the size and PID controllers. This will depend on the height "side walls" and the front of the bevel.
Aluminum angles are used to form the "skeleton" design. Be careful with the "stuffing", the useful and the old VCRs, DVD players and the like. You can bypass the specialized street hawkers.
We are now looking for non-stick pan. Yes, that's the one that you can buy in stores appliances. Here you can and watch high-quality soldering iron for soldering station.
Important! Bring a tape measure. Your task - to find the optimal baking width and depth. The dimensions depend on the height of the IR emitters, and their number.
soldering system control
Let us proceed to the fun. On the trading platform advance order the PIDs (or proportional-integral-differential controllers), and as IR - 3 lower radiator 60 × 240 mm, and the upper one - 80 × 80 mm, not forget to stock two solid relay on 40A. At this stage, you can move on to the tin works, namely to fit the entire structure to the size of our basic elements. After fitting the lid sidewalls and cut PIDs technological holes on the front, underneath the rear wall of the cooler.
The assembly and adjustment of the work of a soldering station
So, after installing the radiator, cooler, and connect all the wires appearance of our soldering station already gets almost finished look. At this stage it is necessary to test the equipment for heating, temperature hold and hysteresis. We proceed to the main assembly IR emitter. Make it easy.
