Patent number: 7320424Abstract: A wire bonding machine for bonding a wire to a semiconductor device. The wire bonding machine includes a wire bonding head having a bonding tool mounted to it. The bonding tool is adapted to attach a wire end to a semiconductor device. A bonding head conveyance system translates the bonding tool in a vertical direction and translates the bonding tool along a first horizontal axis. A work table supports at least one semiconductor device to be wire bonded. A work table conveyance system translates the semiconductor device along a second horizontal axis.Type: GrantFiled: March 29, 2005Date of Patent: January 22, 2008Assignee: Kulicke and Soffa Industries, Inc.Inventors: David T. Beatson, E. Walter Frasch

Patent number: 6960022Abstract: A “hybrid” or macrocomposite guideway, wherein the “traditional” or existing guideway material (e.g., hardened steel) is maintained as the wear resistant, low friction surface intended to be in physical contact with one or more bearings, and further wherein this surface is backed up or supported by a substrate comprising a stiff, lightweight material. This macrocomposite guideway combines the desirable friction and wear characteristics of the traditional bearing materials with the stiffness and low mass of advanced materials. Candidate substrate materials include composites having a ceramic and/or a metallic matrix, monolithic ceramics or monolithic light metals. A cladding comprising the hardened steel wear surface layer may be attached to the rigid, lightweight substrate by adhesive bonding, mechanical fasteners or other mechanical fit such as a friction or interference fit. Preferably, though, the attachment is by means of a metallurgical bond.Type: GrantFiled: July 10, 2003Date of Patent: November 1, 2005Assignee: Kulicke & Soffa Investments, Inc.Inventors: David T. Beatson, E. Walter Frasch, Paul J. Schlosser, Jai R. Singh, David W. McKenna, Craig Emmons
