    摘要: 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. In a particularly preferred embodiment, a silicon carbide particulate reinforced aluminum composite is metallurgically bonded to a tool steel wear surface using an “active” soldering composition. A gib that utilizes such guideways is useful in machines requiring fast and precise movement of one pat relative to another, such as in machines for semiconductor chip fabrication and assembly.

    摘要: A wire bonding machine is disclosed 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. At least a portion of the bonding head is pivotable about a first horizontal axis so as to provide vertical displacement of the bonding tool. The bonding head is also rotatably mounted to the bonding machine so as to permit rotation of the bonding tool about a vertically oriented rotational axis. The machine also includes a work table for supporting at least one semiconductor device to be wire bonded. A conveyance system is used to translate the work table in a direction relative to the bonding head and in a substantially orthogonal direction to the horizontal pivot axis of the bonding head.
