What is the principle of the tin suction device? What are the differences between manual and electric tin cleaners?

Tin suction device is a professional tin suction device in electronic production, mainly used in the production of various circuit boards. Its main function is to absorb excess tin around the solder joints on the circuit board. On the one hand, it can prevent the circuit board from short circuiting, on the other hand, it can also save resources. Therefore, many circuit board manufacturers will design the production process of tin absorption in production. So everyone knows what is the principle of the tin suction device?

Principle of tin suction

1. Working principle of hot air type tin suction device:

The hot air is used to melt the solder, and at the same time, the special solder suction device absorbs the molten solder. Two air pumps are used for the air outlet and suction of the system. Both air output and air intake can be adjusted continuously. The air outlet pump is linked with the heating system to set the temperature of the air outlet. The set temperature and actual temperature are displayed on the LCD. The suction pump can be turned on or off separately. The hot air is used to melt the solder joints (solder), and at the same time, the special solder absorption device is used to absorb the molten solder. And the process of melting and absorbing tin is carried out at the same time, without contacting the circuit board, and removing various components on the circuit board quickly and non-destructively. The temperature and speed of the hot air can be adjusted as needed, and the suction power of the tin suction can be adjusted. Various types of air nozzles and tin nozzles can be selected. Suitable for desoldering of various types of components.

2. Working principle of vacuum tin suction gun type of electric tin suction device:

The electric vacuum tin suction gun has the characteristics of strong suction power, continuous tin suction, etc., and is convenient to operate and high in work efficiency. When working, the heater makes the temperature of the tin suction head reach above 350 ℃. When the solder melts, pull the trigger and the vacuum gun generates negative air pressure to draw the solder into the tin holding chamber instantly. Therefore, the temperature and suction force of the tin suction head are two factors that affect the effect of the tin suction;

The working principle of the electric vacuum tin suction gun is that after the tin suction gun is connected to the power supply, it preheats after 5-10 minutes. One side of the inner hole of the tin suction head is attached to the pin, and the pin is gently turned. After the pin is loose and the solder is fully melted, the trigger can be pulled to suck the tin.

The difference between manual tin suction device and electric tin suction device

Select the manual tin suction device to fit the aperture of the circuit board you want to suck first, then check the tightness of the piston, plug the small hole of the tin suction device with your finger, press the switch, if the piston is not easy to pop into place, then explain The tightness is good.

Electric tin suction device has the advantages of long continuous working time, strong suction and high working efficiency, but at the same time, the requirements for operation are also low. Suitable for use in assembly line operations. The hot air is mainly used to melt the solder, and at the same time, the solder suction device sucks the molten solder. Two air pumps are used for the air outlet and suction of the system. Both air output and air intake can be adjusted. The air outlet pump is linked with the heating system to set the temperature of the air outlet. In actual operation, the set temperature and actual temperature are displayed on the LCD screen. The suction pump can be started or shut down separately.

The above is to introduce to friends about the principle of tin suction device and the difference between manual tin suction device and electric tin suction device. It is hoped that through the introduction of the above contents, everyone can choose the appropriate tin absorber according to their actual needs in production and life.
