Introduction of laser welding machine

The miniaturization of electronic products is an inevitable trend. Compared with other welding technologies, laser welding is more precise and stable, and the efficiency is also higher.

The overall trend of current technology products tends to be more refined, which puts forward higher and higher requirements for the production of connectors. Since the connector plays an important role in circuit connection and signal transmission in the system, once it fails, it will inevitably affect the normal operation of the connected equipment and even the entire system, and the internal solder joints of the connector will affect the reliability of the cable connector itself. one of the key factors.

When using traditional manual soldering, hot air soldering or automatic soldering iron soldering to solder the connector, the damage to the wires will be unavoidable, and it is very easy to form "bridging" between the leads of adjacent solder joints. The use of laser welding technology to weld the connector, the welding speed is fast, the depth is large, and the deformation is small. And laser technology is constantly improving.

In the laser technology five or six years ago, the customer's requirement for the spot is between 0.6 mm and 0.9 mm. Now the products are getting more and more miniaturized, and the requirements for connectors are getting higher and smaller, and the simplification of interaction is always constant trend. At present, the smallest welding spot of our company can reach 0.2 mm or even 0.1 mm, and the pulling force will not lose too much.

At present, our laser technology is very mature and stable. The energy fluctuation of welding is at least 3% or less, or even 2% or 1%, and the quality stability of welding is also greatly improved. In addition, laser equipment is intelligently controlled, controlled by computers, etc., which is very conducive to automation.

Through intelligent control, laser welding is indeed more efficient than traditional resistance welding, for example, dozens of welding spots can be welded in one second. The wide application of laser technology will help to improve product quality and production efficiency.

The principle of laser welding:

The material itself is locally heated and melted by a high-energy beam focused on the surface of the part to form a weld.

The main feature of this process is non-contact welding, and there is no stress and deformation caused by external force; because the heating time is only a few milliseconds, the thermal effect on the material is only limited to the laser focus spot, and the welding heat affected zone is very small; usually multi-point At the same time, the welding technology can reduce the influence of welding deformation on the performance of optoelectronic devices as much as possible; the welding process is measured in milliseconds, and has very high production efficiency, making mass production possible.
