ABSTRACT:
A hybrid die bonder has the ability to change tool holders to accommodate different die sizes. The single pick up head is selectively, magnetically, connectable to any of a plurality of tool holders. An electromagnet in the head holds a magnetic tool holder and a sealed air line is established therebetween. Prior to pick up, the head and tool holder have the same orientation so that precision locating structure therebetween will cooperate to establish a precise axis for the tool holder.
