Abstract:
A die ejection apparatus operable to eject a die from a support has at least two ejector components configured to lift a die located on the support. The ejector components are moveable to a position in which a lifting force is exertable by the ejector components on the support, so as to lift a die located on the support. Movement of the die ejector components is initiated towards the support, and a moment when each of the die ejector components reaches the position is determined. A height offset of each die ejector component relative to a height of another die ejector component is determined upon reaching the said position, and relative heights of the die ejector components are adjusted in dependence upon the evaluated height offset.
