Abstract[English]
A device is proposed for stretching a wafer foil that is held by a film frame carrier and on which a plurality of electronic components is arranged. In particular, the device comprises a holding member for holding the film frame carrier; a tensioning member structured to engage with the wafer foil. Additionally, it comprises a drive that is structured to move at least the tensioning member from a first operational position, at which an intermediate distance between adjacent electronic components is minimal, towards a second operational position, at which the intermediate distance between adjacent electronic components is maximal, wherein a foil engaging part of the tensioning member engaging with the wafer foil is configured to move from the first operational position towards the second operational position in a direction perpendicular as well as in a direction parallel to a plane defined by the wafer foil.[French]
L'invention concerne un dispositif pour étirer une feuille de tranche qui est maintenue par un support de cadre de film et sur laquelle une pluralité de composants électroniques sont agencés. En particulier, le dispositif comprend un élément de maintien pour maintenir le support de cadre de film et un élément de tension conçu pour venir en prise avec la feuille de tranche. De plus, le dispositif comprend un moteur conçu pour déplacer au moins l'élément de tension d'une première position fonctionnelle, dans laquelle la distance intermédiaire entre les composants électroniques adjacents est minimale, vers une seconde position fonctionnelle, dans laquelle la distance intermédiaire entre les composants électroniques adjacents est maximale, une partie de l'élément de tension en contact avec la feuille de tranche étant configurée pour se déplacer de la première position fonctionnelle vers la seconde position fonctionnelle dans une direction perpendiculaire ainsi que dans une direction parallèle à un plan formé par la feuille de tranche.
