How to use soldering station correctly in PCBA processing
Soldering stations are often found in circuit board manufacturers. It has a wide range of uses, from common home appliance repairs to integrated circuit chip ICs. Soldering stations are used as welding tools. Especially suitable for welding operations of precision electronics. Lead on discarded PCBA boards is easily soluble in oxygen-containing water. Solubility causes it to accumulate in the human body and damage nerves; excessive concentrations may cause cancer. As an important part of PCBA circuit board manufacturing, soldering must be lead-free, so lead-free soldering stations came into being.

Analysis of the characteristics of the soldering station

1. Low temperature welding process, low welding temperature, effectively prolong the service life.
2. Provide compensation for different temperatures.

3. Quickly return to temperature, and the temperature drop gap is small.
4. Digital display, convenient for welding operation.

5. Temperature lock function to prevent the uncertainty of welding temperature.

6. The temperature correction function can correct the difference between the set temperature and the temperature of the soldering iron tip.
7. Anti-static, to ensure that sensitive components are not damaged by static electricity.

8. The switch technology can be highly efficient and energy-saving.
9. The cost of consumables is low.

Practical functions of the soldering station

1. Automatic sleep, save energy

When the soldering iron is not used for more than 20 minutes, the soldering station will automatically cool down to 200 degree Celsius. When the soldering iron is picked up again, the temperature will quickly rise to the original setting value, which can extend the life of the soldering iron tip.

2. Password lock temperature

Stable soldering temperature is the guarantee of solder joint quality. The soldering station can conveniently lock the temperature with a password, and others cannot change the set temperature at will.
Precautions for use:

1. Inside the hot air welding gun, there is an overheating automatic protection switch, the gun nozzle overheating protection switch is activated, and the machine stops working. The air volume button (ATPCAPACITY) must be adjusted to the maximum, with a delay of about 2 minutes, the heater can work and the machine will return to normal.

2. After use, pay attention to cooling the body: After the power is turned off, the heating tube will automatically spray cold air for a short time, and the cooling is carried out in stages, without unplugging the power plug.

3. When not in use, please put the handle on the bracket to prevent accidents.

4. For more detailed desoldering instructions, please refer to the manual. Before use, you must read the instructions carefully.

Disassembly of DIP components: According to different circuit substrate materials and different pads, select the appropriate temperature and air volume. Suitable for a variety of single and double panels and solder joints of various sizes. Soldering of SMD components: apply a layer of flux to the position of the removed components, then level the pads, use hot air to blow the flux evenly, align the positions, place the components, and use solder position. In the place where the SMD components should be soldered, pile up all the solder, then remove the excess solder as described above, and use an electric soldering iron to reshape it slightly. By using this method to weld SMD components, the solder joints are beautiful, and the soldering is fast, firm, and reliable. At present, the country has higher and higher requirements for environmental protection and greater efforts in link governance. This is a challenge but also an opportunity for PCB factories. If the PCB factory is determined to solve the problem of environmental pollution, then FPC flexible circuit board products can be at the forefront of the market, and the PCB factory can get the opportunity to develop again.
