Electronic And Semiconductor
Laser technology has been used in electronics for a few years now and it has helped many consumer electronics companies to provide better products for their customers.
With the advancement of science and technology, laser technology has become more prominent in the field of processing and manufacturing, with high efficiency and wide range. Laser welding machines have played an important role in the processing and application of precision parts. Laser welding machine is a kind of welding equipment. It is one of the most widely used welding methods in recent years. Laser welding uses high-energy laser pulses to locally heat the small area of the workpiece, and the energy of laser radiation is transferred to the workpiece through heat conduction. Internal diffusion, the workpiece is melted to form a specific molten pool. Because of the high power density and fast energy release of laser welding, the processing efficiency is much higher than that of traditional welding methods. After the laser is focused, the spot is small, and during the welding process, the adhesion between the two materials can be better, and the surface of the material will not be damaged and deformed, and there is no need for post-processing of the weld.
Laser welding has been widely used in the electronics industry, especially in microelectronic precision parts. Due to the small heat-affected zone, rapid heating concentration and low thermal stress of laser welding, it shows unique advantages in the packaging of integrated circuits and semiconductor device casings. The thickness of the elastic thin-walled corrugated sheet in sensors or thermostats At 0.05-0.1mm, it is difficult to solve by traditional welding methods, TIG welding is easy to weld through, the plasma stability is poor, and there are many influencing factors, but the laser welding effect is very good, and it is widely used.
1. The laser for precision parts welding can be bent and transmitted by optical methods such as optical fibers and prisms, which is suitable for welding of micro parts and other difficult-to-reach parts, and can also be welded through transparent materials.
2. High energy density, high-speed welding can be achieved, heat-affected zone and welding deformation are very small, especially suitable for welding of heat-sensitive materials.
3. The laser for precision parts welding is not affected by electromagnetic fields, does not generate X-rays, and does not require vacuum protection, and can be used for welding of large structures.
4. The insulated conductor can be welded directly without stripping off the insulating layer in advance; it can also weld dissimilar materials with large differences in physical properties.
