Abstract: A semiconductor device is located between a first die-set part and a second die-set part of a press, and the first and second die-set parts are moved relative to each other for punching and shaping the semiconductor device therebetween. At least one parameter is monitored with at least one sensor attached to the first die-set part and/or the second die-set part at different positions of the first die-set part when it is moving relative to the second die-set part. Variations of the at least one parameter at different relative positions of the first and second die-set parts are compared, and a failure is determined to have occurred when the present variation of the parameter is different from its expected variation during normal operation of the press when there is no failure.

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.

Abstract: An apparatus and a method for detecting a failure in a press for punching semiconductor devices are provided, where the method comprises the steps of locating a semiconductor device between a first die-set part and a second die-set part comprised in the press, and moving the first die-set part and the second die-set part relative to each other for punching the semiconductor device therebetween.
