Precision Application of Laser Welding Machine in Microelectronics

Apr. 23, 2021


Laser Welding Machine is a kind of welding equipment. It is one of the welding methods that has been applied and developed very fast in recent years. Laser welding uses high-energy laser pulses to locally heat the small area of the workpiece. The energy of laser radiation is transferred to the workpiece through heat. 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. During the welding process, the adhesion between the two materials can be better, and the surface of the material will not be damaged or deformed, and there is no need to do post-treatment to the weld.

Laser CNC Equipment Supplier tell us that laser welding has been widely used in the electronics industry, especially in microelectronics precision parts. Due to the small heat-affected zone, rapid heating concentration, and low thermal stress of laser welding, it is showing unique advantages in the packaging of integrated circuit and semiconductor device shells. The thickness of the elastic thin-walled corrugated sheet in the sensor or thermostat is In the range of 0.05 to 0.1 mm, it is difficult to solve with 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 is widely used.


The main advantages of precision parts laser welding machine


1.The laser for welding precision parts can be bent and transmitted by optical methods such as optical fiber, prism, etc. It is suitable for welding of micro parts and other parts that are difficult to reach by welding methods. It can also be welded through transparent materials.


2. High energy density, high-speed welding can be realized, heat-affected zone and welding deformation are very small, especially suitable for welding heat-sensitive materials.


3. The laser for welding precision parts is not affected by electromagnetic fields, does not generate X-rays, and does not require vacuum protection. It can be used for welding large structures


4. Insulated conductors can be welded directly without removing the insulating layer in advance; dissimilar materials with large differences in physical properties can also be welded.
