摘要:
The invention relates to a method for removing from a carrier part with a housing arranged thereon, which carrier part contains openings on the side of the carrier remote from the housing which are filled with encapsulating material, wherein the carrier is engaged on two sides by cutting elements provided with at least one cutting edge, which cutting elements are subsequently moved toward each other such that the carrier part is separated from the remaining part of the carrier, characterized in that before the separation takes place the cutting edge projecting relative to a base of the cutting element is urged into the carrier such that the carrier deforms permanently. The invention also relates to a thus manufactured product and to an apparatus for mechanically performing the method.

The invention relates to a method for releasing slug (9, 15, 25) adhering to a stamp (2, 24) in a punching machine, by carrying the stamp (2, 24), after performing a punching operation on a sheet material (4), with the active stroke at least partially through a cutting opening (6) in a cutting plate (3, 13, 21) supporting the sheet material (4), and carrying the stamp (2, 24) during the return stroke back again through the cutting opening (6) in the cutting plate (3, 13, 21) which close-fittingly encloses the stamp (2, 24). The invention also relates to a punching machine (1, 12, 17, 22) for releasing slug (9, 15, 25) adhering to a stamp (2, 24) according this method.

The invention relates to a carrier and to a holder for supporting and engaging semiconductor products during separating of the products using laser light. The invention also relates to a method for supporting and engaging semiconductor products during separating of the products using laser light.
摘要:
The invention relates to a method for removing from a carrier a carrier part with a housing arranged thereon, characterized in that prior to performing the separating operation a notched line is arranged in the carrier on at least one side of the carrier along at least a part of the length of a separating edge to be arranged. The invention also relates to a carrier part with a housing arranged thereon, which carrier part contains openings on the side of the carrier remote from the housing which are filled with encapsulating material, manufactured with the present method. The invention moreover relates to an apparatus for performing the method.
