International Classification:

H01L 23/48
H01L 23/52
H01L 29/40

US Classification:

257762, 257635, 257700, 257748, 257758

Abstract:

A coated electrically conductive substrate has particular utility where there are multiple closely spaced leads and tin whiskers constitute a potential short circuit. This electrically conductive substrate has a plurality of leads separated by a distance capable of bridging by a tin whisker, a silver or silver-base alloy layer coating at least one surface of at least one of the plurality of leads, and a fine grain tin or tin-base alloy layer directly coating said silver layer. An alternative coated electrically conductive substrate has utility where debris from fretting wear may increase electrical resistivity. This electrically conductive substrate has a barrier layer deposited on the substrate that is effective to inhibit diffusion of the substrate into a subsequently deposited layers, which include a sacrificial layer deposited on the barrier layer that is effective to form intermetallic compounds with tin, and a low resistivity oxide metal layer deposited on the sacrificial layer. An alternative coated electrically conductive substrate has particular utility where debris from fretting wear may oxidize and increase electrical resistivity, such an in a connector assembly. This electrically conductive substrate has a barrier layer deposited on the substrate that is effective to inhibit diffusion of constituents the substrate into a plurality of subsequently deposited layers.

International Classification:

H01L 27/00

US Classification:

257762, 438653

Abstract:

An electrically conductive material coated with a plurality of layers, includes a metal or metal alloy substrate; a barrier layer deposited on said substrate effective to inhibit diffusion of constituents of said substrate to said plurality of layers; a sacrificial layer deposited on said barrier layer effective to form intermetallic compounds with tin; a low resistivity oxide metal layer deposited on said sacrificial layer; and an outermost layer of tin or a tin-base alloy directly deposited on said low resistivity oxide metal layer.

International Classification:

US Classification:

Abstract:

An electrophotographic copier having a hot roll fuser assembly. This assembly is slidably supported by a pair of rails. When the fuser assembly is locked into its fusing position, within the copier, it is relatively inaccessible for purposes of inspection, cleaning and/or jam clearance. In its withdrawn, inoperative position, a single manually operable jam clearance handle is operator accessible. Manual actuation of this handle, from a folded to an extended position, is effective to move both a sheet peeler or detach bar, and a sheet transport channel away from the fusing nip. When the handle is moved back to its folded position, the sheet detach bar and transport channel are accurately positioned, and locked in an operative position closely adjacent to the downstream side of the fusing nip, so as to aid in release of the sheet from the fusing nip, and to guide the sheet away from this nip.
