[0002] The die bonder is an important equipment in the semiconductor packaging process. The traditional die bonder uses a syringe dispensing valve to dispense glue to the chip position reserved on the frame. After the dispensing is completed, a swing arm is used to suck the chip from the wafer for mounting, and then output the frame. The existing glue brushing equipment used in the semiconductor field adopts a module embedding body solution, and the module size is small, and automatic positioning and adjustment cannot be achieved, and manual adjustment and positioning are required.
