The invention provides a high-precision alignment and follow-up self-adaptive floating suction head. The upper end of the fixed block is located inside the pressure-bearing block, and the pressure-bearing block and the fixed block move relative to each other. The pressure-bearing block is located between the fixed block and the external equipment. The middle part of the air circuit block is provided with the first installation hole. The lower end of the fixed block is located in the first installation hole. The air joint is installed on one side of the air circuit block, and the upper end of the suction rod is clamped to the Inside the fixed block, the lower end of the suction rod passes through the first installation hole and is fixedly connected to the upper end of the suction head. The lower end of the suction head passes through the base and the cover plate in turn and then contacts and connects to the chip. The two ends of the base are respectively fixedly connected to the air circuit. The lower end of the block and the upper end of the cover plate. The high-precision alignment and follow-up self-adaptive floating suction head described in the present invention can prevent the movement of the device from impacting the chip during the suction process, and has high positioning accuracy, and the structure of the device is compatible with a wide range of chips and satisfies large Stress test, strong adaptive compatibility.
Description
technical field [0001] The invention belongs to the field of IC test equipment, and in particular relates to a high-precision alignment and self-adaptive floating suction head. Background technique [0002] At present, the vigorous packaging and testing market demand puts forward new requirements for the equipment of packaging and testing companies, which can meet the testing needs of micro chips and high-density pins. However, the existing packaging and testing equipment is difficult to meet the testing requirements of tiny chips and high-density pins. The main reason is that the old packaging and testing equipment has poor automatic performance, and generally uses manual or semi-automatic devices, which are difficult to meet the needs of high precision, automation, high pressure, and wide variety. Existing mechanisms use pins, auxiliary rails, etc. to complete. These methods are prone to parts wear, large assembly errors, small degrees of freedom of parts, and certain li...
