Manual iron welding
Electric soldering iron can not leak
Commonly used electric soldering irons use AC power, which is a voltage dangerous to the human body. Leakage of the tip of the soldering iron or damage to the wires are dangerous. Use a multimeter to check the insulation and the heating coil before use.
prevent burns
Soldering iron is an essential tool for electronic assembly and connection. Usually, the surface temperature of the soldering iron tip can reach ℃, but the temperature that the human body can withstand generally does not exceed ℃. Direct contact with the soldering iron tip will definitely cause burns.
The soldering iron should be placed on the soldering iron stand at the right front of the workbench during work. Observe the temperature of the soldering iron. Use the tip of the soldering iron to melt the solder or touch a wet cloth. Do not touch the tip of the soldering iron directly with your hands.
The temperature of the solder in the molten state is above ℃, and the excess solder on the tip of the soldering iron cannot be thrown around.
Solder
The solder is made into a tube, and flux is added inside, and the flux component is mainly rosin. The solder composition is generally a lead-tin alloy with a tin content of 1%.
With the progress of human civilization, people's environmental awareness is gradually increasing. To protect the natural environment, lead-free soldering is an important topic of environmental protection.
The lead-free solder currently in use is tin-silver-copper alloy
Soldering iron placement
After using the soldering iron, pull out the plug and put it on the soldering iron stand.
Soldering iron and solder
The electric soldering iron is the main tool for manual soldering. In addition to the simple electric soldering iron shown in the figure, there are also various electric soldering irons that can adjust temperature, constant temperature and professional applications. The figure shows a variety of functions that can automatically adjust temperature and output. Powerful high-end soldering irons known as spot soldering stations.
Different work properties and soldering points require different grades and types of electric soldering irons. Although tools with higher performance grades are easier to use, human factors are the key. People with high technical levels can still solder well with ordinary soldering irons. .
Solder
Tubular solder wire is commonly used for manual soldering iron welding to make the solder into a tube shape, and flux is added inside, and the flux component is mainly rosin. The solder composition is generally a lead-tin alloy with a tin content of 1%.
With the progress of human civilization, people's environmental awareness is gradually increasing. To protect the natural environment, lead-free soldering is an important topic of environmental protection.
