Working principle of laser solder ball welding

Laser tin spray welding system tin ball from the tin box to the nozzle, after laser heating melting, from the special nozzle spray, directly covered to the pad, without additional flux, without other tools.Adopt tin ball jet welding, welding precision is high, there are requirements for temperature or soft plate to connect the welding area.There is no contact between the solder joint and the welding body in the whole process, which solves the electrostatic threat caused by contact in the welding process.

The laser tinjet welding system has the following characteristics:

1. Laser processing accuracy is high, light spot is small, processing time program control, precision is higher than the traditional process, suitable for small precision parts solder, solder workpiece is more sensitive to temperature.

2. Non-contact processing, non-contact welding caused by static electricity, can be processed in the conventional way is not easy to apply welding parts.

3. The small laser beam replaces the soldering head, and it is also easy to process when there are other interferences on the surface of the workpiece.

4. Local heating, small heat affected zone;There is no static threat.

5. Laser is a clean way of processing, simple maintenance, convenient operation.Repeated operation has good stability.

6. Six-axis working platform, equipped with synchronous CCD positioning and monitoring system, automatic clamping, automatic judgment of whether there is a workpiece, can guarantee the welding precision and yield.

7. Laser tin spray welding system without flux urgent other tools, to ensure the cleanliness of processing.

8. Fast heating speed, accurate positioning, can be completed within 0.2 seconds.

9. The smallest diameter of the tin ball can be 50μm, suitable for high precision welding.

The yield of soldering tin is higher than that of ordinary automatic soldering machine.

11. With visual positioning system suitable for assembly line production.
