What are the reasons for the bubbles in the double head soldering machine?

Double head soldering machine is an automatic soldering equipment. Its principle is to heat and melt solid welding wire through automatic heating electrode, and enter the welding metal with the help of flux to form a firm and reliable welding joint after cooling. At present, the efficiency of double head welding machine is gradually improving, which is mainly used in electronic manufacturing industry. So, what is the reason for tin bubbles in automatic soldering machine? Let me introduce you.

Causes of tin bubbles in double head soldering machine:

1. Moisture problem: due to moisture in the air, especially in spring rainy season and wet weather, intermittent tin or tin explosion may occur due to improper storage and adhesion of solder wire (tin wire) or circuit board.
2. Tin wire processing: in the process of producing welding wire, if the welding wire (tin wire) has cracks, the drawing oil will penetrate into the cracks, which will also lead to tin explosion in the welding process.
3. The main reason is the structure of the tin wire. The structure of the tin wire is that there is tin outside and a small tube inside the tin wire is filled with flux. When welding, high temperature iron contact line, the flux of the line is dissolved rapidly, resulting in a large number of foam explosions. Due to the sealing tube of the welding wire, a large amount of foam leads to high pressure. When the pressure is greater than the pressure of the tube, the explosive welding is formed, thus forming tin.

The above content is an introduction to the causes of double head automatic soldering machines for bubble welding. Automatic soldering machines are widely used in modern society. With the advent of the era of intelligent science and technology and the upgrading of electronic components, the development of electronic components is developing towards miniaturization and miniaturization. The traditional manual welding method can not meet the requirements of production process. Therefore, the use of double head soldering machine is an inevitable choice in the future.
