Die placement head with turret

A system for the placement of dies on a substrate comprising:

• a frame;
• a housing fixed to said frame, said housing comprising a guide channel encompassing a force application rod, which extends from a distal end of said housing, said force application rod configured for linear motion relative to said housing and the application of linear force, a measurement device configured to measure the linear motion of said force application rod, said force application rod further comprising a die placement head holding aperture at a distal end thereof;
• a turret rotatably fixed to said frame comprising a rotation measuring device and a plurality of die placement head holding portions positioned substantially adjacent a periphery of the turret, wherein each die placement head holding portion comprises two concentric apertures, a first aperture and a second aperture, said first aperture positioned adjacent the distal end of said housing and extending fully through said turret, said second aperture positioned on the side of the turret opposite said first aperture and concentric therewith, wherein said first aperture is of a size only slightly larger than that of said force application rod and said second aperture extends only partially into said turret and wherein, upon rotation, each of said plurality of die placement head holding apertures can be brought into alignment with said force application rod;
• and
• a motor fixed to said frame and configured to rotate said turret upon activation.
