Patent ID: 8460491

Claim:
A die bonder, comprising: a die bonding head for picking up a die and bonding the die onto a workpiece; a biaxial drive shaft unit which includes an ascending/descending drive shaft unit for ascending/descending the bonding head and a horizontal-direction drive shaft unit for moving the ascending/descending drive shaft unit in a horizontal direction perpendicular to a direction in which the bonding head is ascended/descended; and a control unit for controlling the biaxial drive shaft unit wherein, the ascending/descending drive shaft unit includes a first ascending/descending drive shaft unit for ascending/descending the bonding head and being able to exert a high bonding load which is higher than a predetermined load on the die via the bonding head, and a second ascending/descending drive shaft unit which is installed on the side of a leading end of the first ascending/descending drive shaft unit, ascends/descends in the direction in which the bonding head is ascended/descended and is able to exert a low bonding load which is lower than the predetermined load on the die via the bonding head.
