Precision Application of Laser Welding Machine in Microelectronics

TIME:2022-12-12View:320

Laser welding machine is one of the welding equipment and one of the welding methods that have been used and developed in recent years. Laser welding makes full use of the laser pulse with high efficiency to heat the local area of the product workpiece. The energy radiated by the laser diffuses to the internal structure of the product workpiece through heat conduction. After the product workpiece is melted, a specific molten pool is generated because of the high power density of laser welding and the fast release of energy, Therefore, the production and processing efficiency is much higher than the traditional welding method. After the laser is focused, the light spot is very small. During the welding operation, the adhesion between the two materials is better, without causing damage to the surface of the material and its deformation, and without post-processing the weld.

 

Since its establishment, Fangtuo has always attached importance to the research and development of laser technology and the development needs of customers, and is committed to providing each customer with more perfect laser welding production and processing solutions.

 

Laser welding has been widely used in electronic industry, especially in micro electronic precision parts. Considering that laser welding has small thermal interference area, fast heating centralization and low thermal stress, it is showing unique advantages in the packaging of integrated circuits and semiconductor device shells. The thickness of elastic thin wall corrugated sheets in sensors or temperature controllers is 0.05-0.1mm, which is difficult to solve by using traditional welding methods. TIG welding is easy to weld through, and plasma stability is poor. The actual effect of laser welding is very good due to many factors, Get extensive use.

 

Specific advantages of laser welding machine for precision parts

 

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

 

2. High energy density, fast welding can be achieved, and the heat affected zone and welding deformation are small, especially suitable for welding of heat sensitive materials.

 

3. The laser used for welding precision parts will not be affected by electromagnetic fields, will not generate X-ray, and will not be protected by vacuum, so it can be used for welding large structures.

 

4. The insulating conductor can be directly welded without stripping the insulating layer in advance; It can also weld different materials with large gap in physical properties.
