The technical application of laser welding machine in the welding of electronic components

Electronic components are components of electronic components and electrical small machines and instruments. They are often composed of several parts and can be used in similar products. Electronic components include: resistors, capacitors, potentiometers, tubes, radiators, electromechanical Components, connectors, semiconductor discrete devices, etc.

The technical application of laser welding machine in the welding of electronic components

Soldering small electronic components on densely packed PCBs is a headache for many technicians. Using traditional soldering iron tips is not only difficult to operate, but also slow in efficiency, and prone to false soldering and missing soldering. Using laser micro-welding technology to weld electronic components is perfect. Solved these problems.

Due to the continuous development of miniaturization of electronic components, small solder joints, high soldering strength and small heat affected zone around the processing point are required. The traditional welding technology has poor appearance quality of the weld, low welding efficiency, and poor combination of the weld ring and the welding part ring, which is easy to cause "de-soldering", etc., so it is difficult to meet the requirements. Precision laser welding machine is a type of laser welding equipment that couples high-energy laser beams into optical fibers, and after long-distance transmission, collimates them into parallel light through a collimating mirror, and then focuses on the workpiece for welding. For the parts that are difficult to access to welding, flexible transmission non-contact welding is implemented, which has greater flexibility.

The laser can create a true weld, melting and mixing the material on all sides of the contact. Laser welding is a welding process that uses the action of a laser to produce instantaneous melting on the metal surface to connect metals. The laser welding machine has the advantages of fast welding speed, large aspect ratio, small deformation, high density, simple operation of the equipment, suitable for working under various conditions, welding of dissimilar and high melting point metals, simultaneous processing and multi-tasking. bit processing and other advantages. The precision laser welding machine is mainly for the welding of thin-walled materials and precision parts, which can realize spot welding, butt welding, stitch welding, sealing welding, etc., with high depth ratio, small weld width, small heat affected zone, small deformation, and fast welding speed. , The welding seam is flat and beautiful, no need or simple treatment after welding, the welding seam quality is high, no pores, it can be precisely controlled, the focusing spot is small, the positioning accuracy is high, and it is easy to realize automation.
