Abstract
An ejector unit for detaching an electronic element from an adhesive carrier has an ejector housing with a supporting deck, a light source disposed therein and an ejector lens. The ejector lens has a protruding face. The ejector lens is disposed and oriented with an optical axis extending between the light source and an opening in the supporting deck, and the protruding face of the lens directed towards the opening. The ejector lens is movable relative to the supporting deck along the optical axis to project the protruding face through the opening against the electronic element for lifting the electronic element.
