Despite the availability and distribution of soldering models, a natural question arises: for what criteria choose a soldering iron? The abundance of proposals is not only great opportunities, but also a kind of problem.
How to choose a soldering iron - power and size
These 2 parameters are closely related to each other, but sometimes there are exceptions. For an ordinary home soldering, you do not need a soldering iron of large sizes. There will be an excellent option if the distance from the tip of the sting before entering the wire will be 25 centimeters. The sting diameter should be within 4 mm with power up to 25 W. With the help of such a soldering iron, it is convenient to solder not only various details, but also chips. Ideally have another 1 soldering iron, but more powerful (by 40-60 watts). It can be used to bridge the boards and the soldering of massive contacts.
Powerful soldering iron (about 100 watts) are used when placing wires in car service. Even more powerful (about 150 watts) apply with a sealing of a saucepan and radiators - metal large-sized things. 500 watt soldering iron is the most powerful and applied exclusively in construction.
If you are already an experienced spider, then you may need a soldering station. With its help, the quality of the soldering is improving several times, and most importantly, work is performed much faster. In addition, the soldering station has many advantages:
- the presence of a convenient bath and a soldering iron cleaning stand;
- the ability to adjust the heating temperature;
- maintaining a constant temperature in the stare.
The most important are the first 2, because such accessories would have to buy similar accessories separately.
How to choose a soldering iron - the shape of the sting
At this option, when choosing a soldering iron, you should also pay attention. In stores you can now find soldering clothes with the most diverse stals: needle, cone, a blade ... to advise what to choose, it will not work: everyone soldes how it is convenient. It will not be superfluous to have a set of vanes of different sizes. Properly selected sting is the key to successful work. We recommend you to buy several flat and thin conical stalls, as well as one large for the decay of the microcircuit.
How to choose a soldering iron - sting resistance
This is another very important characteristics of the soldering iron. The experienced soldiers know how often you have to change sting. Pay attention to heat-resistant sting that do not react to long-term exposure to high temperatures.
How to choose a soldering iron - Important little things
In addition to the above criteria, there are little things that can simply be forgotten. Do not forget about the availability of thermal insulation of the handle. It depends on how well it is protected from the heating part. The sting of the soldering iron is adjustable using a screw on the housing. This technology is provided not on each soldering iron - it is necessary to pay attention to it. A regular stripping of sting is baptized and it will have to fight.
Extra Tools for Soldering
So that you can start a soldering, you need to prepare a workplace. The main thing is good lighting. It is equally important to properly equip the table specifically for soldering. It contains the planks for which the soldering iron is put. The surface is covered asbestos. This is necessary for safe operation with acids and solvents. You will also need such tools:
- tweezers;
- stationery knife;
- thin awl;
- nippers;
- file;
- needle from the syringe.
Do not buy cheap Chinese soldering iron - they will blown or just explode when heated. In a normal soldering iron, resistance should be 2 kilomas. Choosing a soldering iron on the market immediately assemble the multimeter and measure the resistance of the soldering iron you like, and only then buy it.
If we talk about reliability, the best option will be the usual Soviet soldering iron. Domestic soldering rooms are distinguished by a very long time of work. Chinese soldering tanks worth $ 4-5 will be no worse. Choosing a soldering iron in power, consider what it is less, the longer the device will last.
Note, if you solder chips, then be sure to go ground. It will avoid a possible impact of static electricity. Even a small spark is capable of imparting irreparable damage to the chip.
