  • Patent number: 6870362
    Abstract: In a docking apparatus for coupling a first apparatus consisting of a handler or prober and a second apparatus consisting of a testing head for electronic components, at least one locking unit is provided having an axial insertion opening for inserting a locking pin. In the area of the insertion opening, a plurality of balls are arranged, between which the locking pin is insertable. Furthermore, a ball clamping sleeve is provided, which by means of an axial displacement causes a radial movement of the balls and therefore fixes the locking pin.

  • Patent number: 6836109
    Abstract: In a guiding apparatus for positionally accurate docking of a testing head for electronic components to a handler or prober, a guiding pin is provided, arranged to be displaceable in a direction normal to its longitudinal direction on an attachment block attached on a testing head or handler/prober. Within the attachment block, a taper pin is provided longitudinally displaceable and carrying a taper tip on its end facing the guiding pin. The guiding pin has a centering recess on its side facing the taper pin. The taper tip can be brought into and out of engagement with the centering recess, wherein by inserting the taper tip into the centering recess a predetermined position of the guiding pin with respect to the attachment block, and therefore with respect to that device, which carries the guiding pin, can be achieved.

  • Patent number: 4993588
    Abstract: An apparatus for separating objects of the same kind, in particular electronic components such as integrated circuits (IC's), that are delivered in succession in a sloping delivery passage, the apparatus having a stop member arranged in the region of the delivery passage that is displaced substantially transverse to the direction of delivery so that it holds back or holds fast the respective foremost object, and having a control circuit (P) that cyclically controls the displacing movement of the stop member, is to be designed so that while ensuring a relatively long service life it is suitable for use for different components, in particular with regard to their length.

  • Patent number: 4908126
    Abstract: An apparatus for testing and sorting electronic components (33), in particular IC's, is directly mounted on the mounting (2a, 2b to 10a, 10b), preferably forming part of a manipulator, for a test computer. In order to convey the components (33) between an input magazine (16), a testing head (20) and an output magazine (17) a suction head (20) is provided which is movable on a carriage guide (15) and which may be lowered. The mounting forming part of the manipulator permits the test computer (1) and the whole apparatus arranged on a slope so that the components (33) in the magazine rods (26) of the input magazine (16) and the output magazine (17) slide forwards under gravity.

  • Patent number: 4889242
    Abstract: In a device for testing and sorting electronic components, and more particularly integrated circuit chips, the untested components are arranged in parallel magazine channels, which are arranged on a gradient, of an input magazine. The tested components are collected in an output magazine set up in the same way. The magazines are to be suitable, more particularly, for taking up CC (chip carrier) components. These components have a free rear surface upon which they can slip in the magazine channels arranged on a gradient. The magazines consist of a flat base plate (15), upon which guide rails, which are T-shaped in cross section, are mounted in such a way that they limit the magazine channels at the side and at the top, the guide rails being connected with each other to form a block which, as a whole, is capable of being exchanged. The components are tested in a channel, their connecting contacts being connected up with corresponding test contacts.

  • Patent number: 4703858
    Abstract: In the case of an apparatus for testing and sorting oblong, electronic components, more particularly integrated chips, the components, which have been supplied in a row, are separated by means of a separating arrangement. The separating arrangement consists of a belt conveyer, which is arranged above a slideway for the components which have been supplied and which takes hold of the components which have been supplied and pushes them forward on the slideway. A control signal, which is emitted by a detecting arrangement which is arranged after the separating arrangement, is used for the purpose of stopping the belt conveyer so that the component, which has just been delivered by the belt conveyer, can, in the first instance, be tested. After testing has taken place, the belt conveyer is set in operation again.

  • Patent number: 4651090
    Abstract: In a device for receiving components (8', 8", 8"'), particularly integrated chips, in receiving portions (15, 19, 20, 21, 22) of an input and/or output magazine of a component testing machine, with a testing device, the receiving portions are formed by providing grooves for each portion, in a support plate (14), at a distance corresponding to the varying distance between connections of the components to be received.
