Five standards to improve the quality of automatic welding machine!

1. When using the automatic soldering machine, the soldering tin shall be heated to: appropriate temperature

We often use automatic welding machines. It is easy to ignore the temperature of the welding parts, resulting in poor welding quality. The temperature of the welding machine must be sufficient. This is necessary because in the welding process, our role is to solidify the welding and heat the welding target, so that tin and lead molecules can obtain enough kinetic energy, damp the lattice constant of the metal material surface, and produce aluminum alloy through welding. The welding temperature is too low, which is conducive to the molecular wetting of the welding material, and can not produce aluminum alloy, which is easy to produce empty welding; If the welding temperature is too high, the welding material will be non-carbide to reduce the formation and evaporation of flux. When the quality of welding material is poor, the PCB on the welding layer will continue to swing.

2. When using automatic welding machine, it shall have the following welding ability

We use the principle of automatic welding machine, because welding is weldable, welding and welding can effectively separate aluminum alloy. In fact, not all natural metal materials have strong weldability, such as tungsten and tungsten. Their weldability with metal is particularly poor, because the ultra-low temperature causes the formation of oxide film on the surface of metal materials, which destroys the separation of metal and aluminum alloy. Therefore, Liancheng Star Network recommends that we use tin plating, gold plating and other methods. Prevent metal surface from rusting.

3. Use automatic soldering machine, can use: solder paste

As we mentioned above, when we use automatic welding machines, some metals cannot be welded, mainly because the metal contains air oxide film, which leads to welding. The function of solder paste is to clean the oxide film on the metal surface. Of course, the small side of the network also mentions different welding processes. Different solder pastes should be selected, such as nickel chromium, stainless steel plate, aluminum and other metal composite materials. If you don't have solder paste, you can't weld it. The automatic welding machine is used to weld the circuit board and other precision electronic equipment. In order to make the solder joint firm, rosin solder paste is generally used.

Pay attention to the welding time when using automatic welding machine:

We usually use automatic welding machines. We must pay attention to the key of welding time. This is very important. The whole welding process includes the time required for the welding metal material to reach the welding temperature, the full utilization, the time required for the metal material, and the time and part of the aluminum alloy. At the same time, the welding time should not be too long, and the electronic equipment or welding position cannot meet the requirements.

5. When using the automatic soldering machine, pay attention to the welding surface:

This is a matter that Z is easy to be ignored, and it is also one of the important factors affecting the welding quality. Usually, employees do hundreds of welding every day. It is easy to neglect the hygiene of the weld, because the weld surface must be cleaned tirelessly to obtain good clearance and make the weld better. Even the weld with good weldability will form oxide film and oil on the weld surface due to storage or oxidation, thus damaging the water. Please clean the dirty film carefully before welding, otherwise the welding quality cannot be guaranteed.
