Abstract
A die bonder includes a conveyor, a pre-heater, at least one carrier, a paste-dispensing mechanism, a die taking/placing mechanism, and a heater. The conveyor continuously operates in a ring-shaped manner. The carrier is carried on the conveyor to position the substrate. The pre-heater heats the substrate to eliminate the moisture in the substrate. The paste-dispensing mechanism dispenses an adhesive agent onto the substrate. Then, the die taking/placing mechanism places a die onto the substrate at a position where the adhesive agent is dispensed. Finally, the heater is used to cure the adhesive agent so as to bond the die to the substrate.
