Abstract:
A semiconductor device (10) having a package (11) of a single in-line type comprises a semiconductor chip (15), a package body (11) that accommodates the semiconductor chip (15) therein and defined by a pair of opposing major surfaces (11a, 11b), a plurality of interconnection leads (14) held by the package body to extend substantially perpendicularly to a bottom surface (11 f ), wherein each of the interconnection leads consists of an inner lead part (14b) located inside the package body and an outer lead part (14a) located outside the package body, the outer lead part being bent laterally at a boundary between the inner part and outer part, in one of first and second directions that are opposite from each other and substantially perpendicular to the opposing major surfaces (11a, 11b) of the package body. The semiconductor device further includes a plurality of support legs (12a - 13b) extending laterally at the bottom surface (11 f ) of the package body for supporting the package body upright when the semiconductor device is placed on a substrate.
Abstract:
A flat package (10) for semiconductor integrated circuit devices allows edge-mounting and surface-mount. The package may be molded plastic (12) containing a semiconductor chip (11), and flat leads (14) extend from one edge of the package. The leads are bent to provide an area (18) to solder to conductors on a PC board. Mechanical positioning, mechanical support and spacing are provided by studs (15) extending from the edge of the package adjacent the leads. The studs have stops (17) formed at a position even with flat outer surfaces of the bent leads; the portion outward of the stops fits into holes in the PC board.
Abstract:
A vertically mountable semiconductor device including a plurality of stub contacts extending perpendicularly from a bottom edge thereof. The stub contacts may be formed by trimming the leads of an existing vertical surface mount package. A complementary alignment device includes a receptacle for receiving the vertically mountable semiconductor device. The alignment device is attachable to a carrier substrate. Upon attachment of the alignment device to a carrier substrate and insertion of a vertically mountable semiconductor device into the receptacle, a contact element applies a downward force to the vertically mountable semiconductor device to establish and maintain an electrical connection between the vertically mountable semiconductor device and the carrier substrate.
Abstract:
A method for securing a semiconductor device to a carrier substrate includes inserting a semiconductor device with a plurality of stub contacts extending from a bottom edge thereof into a receptacle of an alignment device associated with the carrier substrate. Upon attachment of the alignment device to a carrier substrate and insertion of a vertically mountable semiconductor device into the receptacle, the semiconductor device is biased so as to establish and maintain electrical communication between the semiconductor device and the carrier substrate.
Abstract:
A semiconductor device package including leads with substantially planar exposed portions extending from a bottom edge of the package. The exposed portions of the leads may comprise stub contacts extending perpendicularly from the bottom edge. The exposed portions of the leads may be substantially rigid or nondeformable. A complementary alignment device that may be used with the semiconductor device package may include a receptacle for receiving the semiconductor device package.
Abstract:
Disclosed is a device comprising a circuit having an active side and a non-active side, a package enclosing the active side of the circuit and not enclosing a portion of the non-active side of the circuit, and a lead having a first end connected to the active side of the circuit via a lead-over-chip connection, and having a second end extending from the package. Also disclosed is a device comprising a circuit and a lead formed from a flexible conductor, with the lead having a first end connected to the circuit.
Abstract:
An integrated circuit is provided having an alignment feature integral with the lead frame. The integrated circuit includes a lead frame coupled with a semiconductor die, and is partially encapsulated in insulating material. The lead frame has the alignment feature therein. The alignment feature includes a cut out on the lead frame taking the form of a semicircle, protuberance, apertures, or slots. Alternatively, the alignment feature includes a removably coupled tab. After testing of the integrated circuit has been completed, the alignment tab is removed from the integrated circuit. The alignment feature can also be provided on a heat spreader which is attached to a side of or within the lead frame package.
