Soldering iron is a manual tool for welding.
There are many soldering iron on the market.
They come in a variety of sizes and shapes.
What kind of soldering iron to choose for yourself depends on the welding items you plan to do and how often you plan to use it.
This manual will cover the selection of soldering iron, which will be used for welding and dismantling items in electronic products
Welding work on the circuit board.
The four main factors to consider when choosing a soldering iron are: 1)wattage 2)
Model 3 of soldering iron)
Temperature Control 4)
The power of the soldering iron is one of the most important factors of the soldering iron.
Most of the soldering iron used in electronic products is in the range of 20-60 watts.
Nowadays, soldering iron with a power of 50 w is very common and it will provide enough heat for most welding items on the board.
Soldering iron with high wattage (40W -60W)are better.
This does not mean that the soldering iron with higher power will apply more heat to the butt welding point.
This means that the soldering iron with higher power has greater power.
Since most welding stations are equipped with power station knobs for setting the iron temperature, the heat at the iron tip can be adjusted.
On the other hand, the low wattage soldering iron (20W -30W)
Can lose heat faster than it can againheat itself -
This leads to poor solder joints.
There are generally 4 different types of soldering iron :-
Welding pencil-
Welding station-
Welding system (
Rework/repair station)-
The welding pencil is very simple (and very cheap)
Welding tools that can only be used for simple operation-it-
Your own project.
The price of welding pencils is $10-30.
I do not recommend using welding pencils in fine soldering items as they do not provide any control over the iron head temperature.
Applying too much heat during welding can damage the assembly and peel off the track on the board.
The welding station consists of welding pencils connected to the power station.
The power station has a control device to set the required temperature at the tip of the soldering iron.
Some welding stations are equipped with electronic temperature control-
This means that you can set and keep the temperature of the iron very precisely.
The power station automatically keeps the iron head at the right temperature.
The price of the welding station is $40-150.
Welding stations can cover most welding items including through welding
Hole Assembly and very fine surface
Install components as small as 0603 and 0805.
Weiler is the most popular brand for welding stations, followed by Hakko.
On the other hand, the Aoyue welding platform is a good combination of quality and price.
The most popular welding pad model is WE1010NA Weiler soldering iron, FX-
888 soldering iron, Aoyue 937.
WE1010NA Weiler soldering iron is the latest model of Weiler soldering iron.
It is an improved version of WESD51 Weiler iron.
Rework/repair system work/repair system is a complex welding system, mainly for industrial or high
Mass production facilities.
Welding system usually consists of soldering iron, heat-air gun, de-
Hot welding guntweezers, etc.
The price of the welding system is within the range of $250. $2500.
Pace is the most popular brand for these welding systems.
Rework MBT is a popular model for Rework/repair systems
Pace MBT 250 SDPT-
350, proud month 2702.
The main part of the welding gun is a transformer that converts 110 v ac to a lower voltage.
The secondary winding of the transformer is only one circle.
In this way, the secondary of the transformer produces a very low voltage and a few hundred amps, because the primary of the transformer is connected to 110 v ac, and the secondary winding of the transformer has only one turn.
This high current is routed through the copper tip of the welding gun, resulting in the high current flowing through the tip of the welding gun being quickly heated.
Welding guns can be turned on and off quickly and easily, and their worm start time is very short.
However, I do not recommend doing fine work on the board because they generate too much heat and therefore damage the components on the board or board.
The price of the welding gun is within $20. 70.
