Product features
In the annular welding head, the ball dividing plate sends the solder balls to the nozzle mouth alone, and then melts and sprays the solder balls at the nozzle mouth to the OIS pin position with the laser. In the whole process, nitrogen plays a role of auxiliary supply, preventing oxidation of tin balls and judging whether there are tin balls.
The equipment adopts high-precision visual positioning correction system and linear motor motion system to realize high-speed fine welding.
