What does a "die bonder" in the semiconductor industry do? What is the approximate principle?

The simplest way is to coordinate the visual positioning with the action of the machine structure. The camera of the machine is like its eyes, which is a window to obtain production information, and then this information is processed and calculated by the PC or Firmware part, and then by the computer. The CPU controls the motor mechanism to operate, and the servo feedback system is also a phase-locked loop system that can track and control the operation status at any time, and then complete a Cycle, and some post bond detection, which will also have a video signal. It can be used as a reference to make some corresponding adjustments or corrections, etc.

After that, the automatic production is repeated according to this process.
