Abstract

The invention discloses a turret-type die bonder, which relates to the field of chip manufacturing. The turret-type die bonder includes a correction and compensation system, a die picking system, a dispensing system, a die bonding system, a turret system and a detection system. The correction and compensation system is used for finely adjusting the position of a chip on a wafer disc loaded with achip. The die picking system is used for picking up the chip on the wafer disc. The dispensing system is used for dispensing a lead frame. The die bonding system is used for bonding the chip and the lead frame. The turret system transfers the chip, which passes through the die picking system, the dispensing system and the die bonding system in turn. The detection system is used for position parameter compensation and correction before chip picking and before die bonding. By adopting the combination of a set of turret-type multi-swing-arm suction nozzle system and three sets of voice coil motorpressing mechanisms as well as a high-speed computer operation control system and a high-speed industrial camera video processing system, the processes of continuous die picking from the wafer disc,dispensing and die bonding are realized.

Description

technical field [0001] The invention relates to the field of chip manufacturing, in particular to a turret-type crystal bonder. Background technique [0002] With the development of semiconductor chips and the country's strong support for the semiconductor industry, the market's demand for semiconductor chip packaging equipment is increasing. The precision, speed and reliability of the equipment are getting higher and higher. However, the equipment imported from abroad is expensive, and the domestic die bonder equipment needs to be improved not only in the die bonding speed, but also in the repositioning rate and reliability. The initial investment in small and medium-sized enterprises is large, which seriously restricts the development of small and medium-sized enterprises. Contents of the invention [0003] According to the deficiencies of the prior art above, the technical problem to be solved by the present invention is to propose a turret-type crystal bonder, which ...
