ABSTRACT:
A die ejector chuck is provided with a central housing and an outer housing and the central housing is provided with a die eject collar which extends through an aperture in the outer housing. A preselected die on a flexible adhesive tape is positioned over the die eject collar and a source of vacuum is applied to apertures in the outer housing. The outer housing is moved upward and away from the central die eject collar so as to stretch the flexible adhesive tape supporting the preselected die. The adhesive tape is pre-peeled and pulled away from the preselected die which subsequently is further separated from the adhesive tape by a die eject pin to permit the preselected die to be picked up with a die collet acting with a light pulling force on the active surface of the preselected die.
