With the advent of the fiber laser era, the application level of laser technology is gradually moving towards a new level. Laser welding machines have been widely used in the electronics industry, especially in microelectronic precision parts. Today Leapion Laser introduces the application of laser welding machine in the precision electronics industry.
Nowadays, our life is inseparable from 3C electronic products, such as: computers, tablets, mobile phones, etc., and these products are getting smaller and smaller and more refined. These precise electronic components are components of electronic components and small and medium-sized machines and instruments. They are composed of several parts. Electronic components include resistors, batteries, tubes, radiators, connectors, and semiconductor devices.
The welding of electronic components is a very troublesome problem. The traditional welding method is relatively slow in efficiency, and there are phenomena such as missing welding. Then, the use of laser welding technology can solve this problem well.
1. The laser for precision parts welding can be bent and transmitted through optical methods such as optical fibers and prisms. It is suitable for the welding of micro parts and parts that are difficult to reach by other welding methods.
2. Laser welding has high energy density, can achieve high-speed welding, and has small heat-affected zone and welding deformation, which is especially suitable for welding of heat-sensitive materials.
3. Laser welding of precision parts 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. Insulated conductors can be welded directly without stripping off the insulating layer in advance; dissimilar materials with greatly different physical properties can also be welded.
5. 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 the sensor or thermostat is 0.05-0.1mm, which 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. Laser welding has a good effect and has been widely used. Applications.
6. After the laser is focused, the spot is small. 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.
7. Laser welding of precision parts can realize spot welding, butt welding, stitch welding, sealing welding, etc., with high depth ratio, small weld width, small heat affected zone, small deformation, fast welding speed, smooth and beautiful weld.
8. No treatment or simple treatment is required after laser welding, the welding seam is of high quality, non-porous, can be precisely controlled, the focusing spot is small, the positioning accuracy is high, and it is easy to realize automation.
