Due to the small heat affected zone, rapid heating concentration and low thermal stress, laser welding shows unique advantages in the welding of precision micro-components in the packaging of integrated circuits and semiconductor device shells. The following describes the advantages of laser welding technology in the welding of precision micro-components.
The thickness of the elastic thin wall corrugated sheet in the sensor or thermostat is 0.05-0.1mm, which is difficult to be solved by traditional welding methods. The traditional arc welding technology is extremely penetrating, and a little carelessness may penetrate the corrugated sheet. And it will also affect other areas, and the stability is poor. Because the laser welding machine technology has strong stability, the laser beam is easy to control, and the thermal influence range is small, it can be easy to complete the corrugated sheet welding work. There are many influencing factors, but the laser welding effect is very good, and it is widely used.
The welding heat input of the laser welding machine can be controlled and reduced to a low demand, and the metallographic variation range of the welding heat affected zone can be small. The laser welding machine can implement micro-welding processing on the precision micro-components of the mobile phone, and the laser output with high stability can weld various metal precision micro-components on the electronic products such as the mobile phone, and the welding is firm and will not cause deformation.
The advantages of laser welding technology in the welding of precision micro-components:
1. No electrode, no electrode contamination or damage concerns. The wear and deformation of the tool can be minimized.
2. Four-dimensional table, using imported servo control system, optional rotary table, can achieve spot welding, linear welding, circular welding and other automatic welding, wide range of application, high precision, fast speed.
3. Welding is not limited by distance, can switch the device to transmit the laser beam to multiple workstations, easy to automate high-speed welding;
4. The weld quality is high, smooth and beautiful, no porosity, and the toughness of the welded material is at least equivalent to that of the parent material.
5. The laser beam is not disturbed by the magnetic field, which is easy to accurately align the weldment and has high welding accuracy;
6. It can weld the parts that are difficult to access, and implement non-contact long-distance welding with great flexibility.
