Abstract: A chip handling apparatus, unit and method is presented. The chip handling apparatus comprises a chip supply station; a chip mounting station; and one or more chip handling units configured to pick a chip from the supply station, transport the chip to the mounting station, and place the chip at a mounting location; wherein each chip handling unit is configured to temporarily retain the chip in a defined position relative to the chip handling unit. The chip handling apparatus further comprises means for inducing sonic vibrations in the chip when retained by one of the chip handling units; and means for measuring the vibrations induced in the chip.
Abstract: A pick tool for picking a planar object from a supply station is presented, in particular to be used for picking a semiconductor die from a carrier tape, said pick tool comprising: a work surface, said work surface comprising at least one contact region that may be brought into contact with a first surface on a first side of the planar object; one or more vacuum outlets in the work surface that may be connected to a vacuum source to allow for temporarily fixing the planar object to the work surface; and wherein a flexible seal is provided to maintain vacuum if the planar object becomes deformed.

Abstract: An apparatus (1) for fixing a planar object, in particular a substrate (2), on a working area (4) by means of vacuum is provided with an at least partly transparent bearing plate (5), one side of which forms the working area and which has a rear side arranged at a distance from the working area with a radiation-reflecting structure (7). The bearing plate additionally has vacuum channels which can be connected to a vacuum line and which open into the working area. In order to illuminate the substrate as homogeneously as possible by means of transmitted light, at least one light source (10) is provided, the radiation of which can be fed into the bearing plate. In addition, the working area is preferably operatively connected to a heating apparatus (11), so that the substrate (2) can be heated.
Abstract: The invention relates to a film (2) which comprises a component (1) to be detached therefrom. Said film is placed in the area of the component on a detaching tool (5) that is provided with at least one supporting element (6) for the film, which extends in a plane of support (11). The film is sucked against the support element (6) and partially under the plane of support by exerting negative pressure. The area of the supporting element is provided with at least one surface section (8) which extends in the plane of support when the detaching process begins, and which can be displaced, once the component (1) is grasped by a suction tool (4), plane-parallel to the plane of support while the negative pressure is maintained. The invention allows to control the detaching process of the film in a controlled movement without damaging or displacing the component.
