The advantage of laser welding

1. Differences in contact methods

Soldering iron welding generally uses contact welding, which is likely to cause the surface of the product to be scratched. During welding, the soldering iron tip will put a certain pressure on the welding workpiece, causing the solder joint to sharpen, and there is a transmission risk. In contrast, laser welding using non-contact welding can better avoid these risks. It will not cause mechanical damage to the product, and will not cause pressure on the welding components.

2. Adaptability differences

When welding some workpieces with more complicated surfaces, the soldering iron tip and wire feeding device occupy a large space, and the components on the surface of the workpiece are easily interfered with. The laser solder wire feeding device occupies a small space and is not prone to interference. In addition, the spot size of the laser soldering equipment can be automatically adjusted to adapt to various types of solder joints, which can meet the needs of replacing more products, while the traditional soldering machine needs to replace or redesign the soldering iron tip. Therefore, the adaptability of laser soldering is stronger.

3. Differences in the impact on welding components

Soldering iron welding generally uses the whole board to heat, which will undoubtedly have a bad effect on some of the existing thermal components. During the laser soldering process, the laser only heats the part irradiated by the light spot, and the local temperature rises faster and can effectively reduce the impact on the devices around the solder joints.

4. Differences in consumption materials

From the aspect of material saving: soldering iron tips are mostly used to provide the required energy in the soldering iron welding process, but with the aging and wear of the soldering iron tip, the temperature cannot meet the welding requirements, and the soldering iron tip wear caused by contact welding Seriously, the soldering iron tip needs to be cleaned and replaced frequently, which increases the welding cost. In laser welding, the laser is used as the heat source to melt the tin material into the gap of the weldment to connect it, and there is no equipment and consumables to reduce the production cost.

From the perspective of energy saving: because the heating method of the traditional soldering process is the whole plate heating, it will cause more meaningless loss of heat and increase the loss of electric energy; while the local heating of laser welding produces less heat and achieves better energy saving effect.

5. Higher processing precision

Due to the limitation of the traditional soldering iron welding process and the control method, the wire feeding and welding accuracy are limited; while the laser soldering technology has rapid heating and rapid cooling characteristics, which can make the metal compound produced during welding more uniform and fine, and the mechanics of the solder joint Performance is better. Local heating is more conducive to welding heated components and heat-sensitive components on a circuit board with dense components and solder joints, and can reduce the bridging between solder joints after welding.

6. Better safety performance

The non-contact laser soldering method reduces the use of rosin and the residue of combustion-supporting agent, and reduces the generation of harmful smoke, slag, and waste. The laser soldering equipment has been able to accurately control the temperature of the solder joints in real time and prevent burning, and can greatly reduce The difficulty of debugging the welding process reduces the damage to the operator.
