Patent ID: 8701276

Claim:
A placement head assembly for assembling an integrated circuit die on a carrier, said assembler comprising: a support assembly for supporting a wafer with the integrated circuit die thereon; a die picking assembly for picking the integrated circuit die from said wafer; a die placement assembly having a placement head for placing the integrated circuit die onto the carrier; and a die conveyance mechanism for conveying the integrated circuit die from the die picking assembly to the die placement assembly; wherein said placement head comprises: a Z-axis stage mounted on a frame of the die placement assembly, said Z-axis stage being displaceable along a first axis relative to the frame; a Y-axis stage mounted on the Z-axis stage, the Y-axis stage being displaceable along a second axis perpendicular to the first axis; an X-axis stage mounted on the Y-axis stage, the X-axis stage being displaceable along a third axis perpendicular to the first and second axes; a die placer head mounted to the X-axis stage for receiving the die from the die conveyance mechanism and to place the die onto the carrier, the X-axis, Y-axis and Z-axis stages cooperating to position the die placer head relative to the carrier; and air heater tubes connected to the die placer head for heating the die placer head thereby bonding the die to the carrier.
