With the emergence of the solder paste laser welding machine, it gives everyone another choice when buying a welding machine, but it also brings more problems. For laser welding machine, everyone may stay in the old welding process, so when choosing a welding machine, they always don't know how to choose between the old welding machine and the laser welding machine. The reason why people are so hesitant is because they don't know enough about laser welding machines. Some people who use laser welding machines ask, "What is a laser welding machine? What industries can use laser welding machine?
The basic principle of Zichen cartridge solder paste soldering machine is completed through the three processes of "wetting", "diffusion" and "metallurgy". Solder through the high-energy laser pulse in a small area of local heating and melting, wetting the solder joints and more solder inherent tension to the solder joints diffusion, and the solder joints of the metal layer contact to form an alloy layer, so that the two are firmly combined. It is a new type of welding, mainly used for welding thin-walled material precision parts, can realize spot welding butt welding stacked sealing welding, etc., weld width is small, small heat-affected zone of small deformation, welding speed, weld seam flat, high welding quality, precision can be accurately controlled, high positioning accuracy, and it is very easy for customers to realize automated production for customers to solve the cost of labor, production capacity, efficiency and management difficulties of the traditional old-fashioned Soldering machine brings troubles.
Application of syringe type laser soldering machine
The welding process of laser soldering is divided into two steps: firstly, the laser solder paste is preheated, while the paste is preheated, the solder joint will also be preheated, and then the high temperature melts the paste into a tin liquid, allowing the tin liquid to completely wet the pad, and ultimately forming a weld. The use of laser solder paste welding, with high energy density, high heat transfer efficiency, non-contact welding, solder can be solder paste or wire, especially suitable for welding in a narrow space or small solder joints precision welding. As well as for products with particularly high quality requirements, products that require localized heating.
In response to the electronic market demand for automatic precision soldering, such as in the BGA outer lead bump, Flipchip on the bump, BGA bump rework, TAB device package lead connection, sensors, inductors, hard disk heads, camera modules, vcm voice coil motors, CCM, FPC, optical communication components, connectors, antennas, speakers, speakers, heat-sensitive components, photosensitive components and other products that are difficult to be soldered by traditional methods, the product is suitable for the soldering of small solder joints. components and other products that are difficult to weld in the traditional way, the application of laser soldering equipment is becoming more and more widespread.
Almost all of these industries use laser welding machines. The advantages of laser welding machines are energy concentration, no contamination, small weld joints, wide range of weldable materials, high applicability, high efficiency and high speed welding. Also, the following requirements apply to laser welding.
- Products with requirements for weld seams that need to be welded are welded by laser welding, which is not only small, but also does not need to be welded.
- Products with a high degree of automation in which the laser welding machine can be programmed manually and the path is automated.
- Products to be welded at room temperature or under special conditions can be stopped at room temperature or under special conditions and the laser welding equipment is easy to install.
- Some inaccessible parts require laser welding equipment It can weld inaccessible parts and realize non-contact long distance welding with high sensitivity.
