A method of applying bonding energy to form a bond between a portion of a wire and a contact of a bonding location using a wire bonding machine is provided. The method includes: (1) moving a bonding tool towards the contact; (2) detecting when a portion of the contact () is pressed against a device supporting surface () of the wire bonding machine; and (3) applying bonding energy to the portion of the contact such that a bond is formed between the contact and the portion of wire.

Closed loop wire bonding methods and bonding force calibration

A bond head assembly for use with a bonding machine includes a wire bonding tool and a link mechanism coupled between the wire bonding tool and the wire bonding machine. The link mechanism includes a frame, a plurality of arm links pivotably connected to the frame, and a tool support member supporting the wire bonding tool and pivotably connected to each of the arm links.

Bond head link assembly for a wire bonding machine

A device clamp configured for use with a wire bonding machine is provided. The device clamp includes a body portion defining at least one device aperture. Each of the at least one device apertures is configured to be positioned adjacent a bond site area of the wire bonding machine. The body portion includes a inlet port for receiving a fluid from a gas supply source. The body portion defines a fluid path from the inlet port to the at least one device aperture.

Device clamp for reducing oxidation in wire bonding

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.

Linear split axis wire bonder

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 &#x201c;active&#x201d; 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.
