With the development of The Times, the industry is gradually moving towards the 2.0 era, reducing time and labor costs. The automatic heating of the soldering iron will heat the solid wire until it melts, and the flux will enter the interaction between the solder and the metal material, which will produce a solid and reliable solder joint after cooling. For Liancheng Xiaobao, the birth of automatic welding machine, accelerated the process of the current chemical industry, is an indispensable tool for modern processing and manufacturing. So what is the standard of automatic welding machine? Thus, the efficiency of precision welding is effectively improved.
1, the use of automatic solder machine, solder should be heated to: appropriate temperature
We often use automatic soldering machines, it is easy to ignore the temperature of the welding part, resulting in poor welding quality. The temperature of the welder must be sufficient. This is necessary because during the welding process, our role is to solidify the solder and heat the solder target so that the tin and lead molecules gain enough kinetic energy to damp the lattice constant on the surface of the metal material to produce aluminum alloys by welding. The welding temperature is too low, which is conducive to the molecular wetting of the welding material, can not produce aluminum alloy, and is easy to produce air welding; If the welding temperature is too high, the welding material will be in a non-carbide form, thus reducing the formation and evaporation of flux. When the quality of the welding material is poor, the PCB on the welding layer will continue to swing.
2, the use of automatic soldering machine, welding should have: welding ability
We use the principle of automatic soldering 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, tungsten, etc. Their weldability with metal is particularly poor, because the ultra-low temperature during welding causes the surface of the metal material to form a layer of oxide gas film, which destroys the separation of the metal and the aluminum alloy. Therefore, Xiaobian suggests that we use tinning, gold plating and other methods. Prevent rust on metal surfaces.
3, the use of automatic soldering machine, can use: solder paste
What we mentioned above is that when we use the automatic soldering machine, some metals can not be welded, mainly because the metal contains air oxide film, resulting in welding. The function of the solder paste is to clean the oxide film on the surface of the metal. Of course, the network editor also mentioned that the welding process is not the same. Different solder paste 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. Automatic soldering machine welding circuit board and other precision electronic equipment, in order to make the solder joint firm, generally use rosin solder paste.
4. Pay attention to welding time when using automatic welding machine:
We usually use automatic soldering machine, must pay attention to the welding time is the key. This is very important. The entire welding process includes the time required for the welding metal material to reach the welding temperature, the time required for the paste to be fully utilized and the metal material to exist, the time of the aluminum alloy, plus a portion. At the same time, the welding time should not be too long, and the electronic equipment or welding position is too short to meet the requirements.
5, the use of automatic soldering machine, pay attention to the welding surface:
This is something that is easily overlooked, and it is also one of the important factors affecting the quality of welding. Typically, employees do hundreds of welds a day. The hygiene of welds is easy to overlook because the surface of welds must be cleaned tirelessly after achieving a good clearance to make the welds better. Even welds with good weldability, due to storage or oxidation, will form oxide gas film and oil on the surface of the weld, thus destroying water. Clean the dirty film carefully before welding; otherwise, the welding quality cannot be guaranteed.
