The working principle of ASM LED die bonding machine:

The ASM die attaching machine transfers the PCB board to the working position on the workbench fixture by the feeding mechanism. First, the dispensing mechanism dispenses the position where the PCB needs to be bonded to the chip, and then the bonding arm moves from the original position to the position to pick up the chip. , The wafer is placed on the expander wafer tray supported by the film. After the bonding arm is in place, the suction nozzle moves downwards, and the thimble moves upwards to lift the wafer. After picking up the wafer, the bonding arm returns to the original position (missing die detection position), bonding The arm moves from the original position to the bonding position, the nozzle is downwardly bonded to the wafer, and the bonding arm returns to the original position again. This is a complete bonding process. When a cycle is completed, the data of the next position of the wafer is detected by machine vision, and the data is transmitted to the wafer tray motor, and the motor is allowed to travel the corresponding distance to move the next wafer to the aligned pick-up wafer position. The glue and bonding position of the PCB board is also the same process, until all the glue positions on the PCB board are bonded to the chip, and then the PCB board is removed from the workbench by the transfer mechanism, and a new PCB board is installed to start a new process. Work cycle.
