Abstract: A split shroud system for a gas turbine engine having a pair of annular-shaped shrouds that each have an inner pocket; to form a pair of inner pockets. Each of the pair of pockets having liner parts that form a circle. Liner parts of one of the pair of pockets facing liner parts of the other of the pair of pockets to form liner part pairs. One of each of said of pair of liner parts has a mutual abutting surface that forms a plurality of slots for accepting a plurality of vane inner trunnions.

Abstract: Methods and apparatus are provided for an electronic panel assembly (EPA) (82, 83), comprising: providing one or more electronic devices (30) with primary faces (31) having electrical contacts (36), opposed rear faces (33) and edges (32) therebetween. The devices (30) are mounted primary faces (31) down on a temporary support (60) in openings (44) in a warp control sheet (WCS) (40) attached to the support (60). Plastic encapsulation (50) is formed at least between lateral edges (32, 43) of the devices (30) and WCS openings (44). Undesirable panel warping (76) during encapsulation is mitigated by choosing the WCS coefficient of thermal expansion (CTE) to be less than the encapsulation CTE. After encapsulation cure, the EPA (82) containing the devices (30) and the WCS (40) is separated from the temporary support (60) and, optionally, mounted on another carrier (70) with electrical contacts (36) exposed.

Abstract: Methods and apparatus are provided for use in manufacturing a device packaging comprising the steps of: positioning a metal substrate such as spring steel on a magnetic plate so as to expose a surface of the metal substrate; placing a first tape layer on the exposed surface of a metal substrate so as to expose a nonstick surface of the first tape layer such as PTFE; placing a second tape layer on the exposed surface of the first tape layer so as to expose a surface of the second tape layer; positioning a mold frame on the exposed surface of the second tape layer; positioning a die within the mold frame; depositing epoxy within the mold frame; curing the epoxy so as to create a molded panel; removing the mold frame; grinding the molded panel to a desired thickness; separating the first tape layer from the second tape layer so as to separate the metal substrate from the molded panel; and peeling the second tape layer from the molded panel.

Abstract: The invention provides an integrated device with corrosion-resistant capped bond pads. The capped bond pads include at least one aluminum bond pad on a semiconductor substrate. A layer of electroless nickel is disposed on the aluminum bond pad. A layer of electroless palladium is disposed on the electroless nickel, and a layer of immersion gold is disposed on the electroless palladium. A capped bond pad and a method of forming the capped bond pads are also disclosed.

Abstract: The invention provides an integrated device with corrosion-resistant capped copper bond pads. The capped copper bond pads include at least one copper bond pad on a semiconductor substrate. An activation layer comprising one of immersion palladium, electroless cobalt, or immersion ruthernium is disposed on the copper bond pad. A first intermediate layer of electroless nickel-boron alloy is disposed on the activation layer. A second intermediate layer comprising one of electroless nickel or electroless palladium is disposed on the first intermediate layer, and an immersion gold layer is disposed on the second intermediate layer. A capped copper bond pad and a method of forming the capped copper bond pads are also disclosed.

Abstract: The invention provides a method of plating an integrated circuit. An activation plate is positioned adjacent to at least one integrated circuit. The integrated circuit includes a plurality of bond pads comprising a bond-pad metal, and the activation plate also comprises the bond-pad metal. A layer of electroless nickel is plated on the bond pads and the activation plate, and a layer of gold is plated over the layer of electroless nickel on the bond pads and the activation plate. An integrated circuit with bond pads plated using the activation plate, and a system for plating an integrated circuit is also disclosed.
