Abstract:
A device comprising a circuit, a lead having a first end connected to the circuit and having a second end, and a deformable structure connected to the second end of the lead. The invention may be embodied on a circuit board, so that the circuit board includes a substrate and a deformable structure connected to said substrate.
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.
Abstract:
A vertically mountable semiconductor device including a plurality of stub contacts extending perpendicular from a bottom edge thereof. 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 semiconductor package includes a semiconductor die, a lead frame wire bonded to the die, and a plastic body encapsulating the die. The package also includes a first heat sink attached to a face of the die, and a second heat sink attached to a back side of the die. Thermally conductive adhesive layers attach the heat sinks to the die, and provide a thermal path therebetween. In addition, the heat sinks project from the plastic body, and have end portions that are sized and shaped to interlock with heat sinks on an adjacent package to form an electronic assembly. In the electronic assembly, the interlocking heat sinks maintain contact surfaces on the heat sinks in physical contact and improve heat dissipation from the packages. An alternate embodiment package includes a thermally conductive encapsulant which attaches a pair of heat sinks, and encapsulates the die.

Abstract:
A process for manufacturing semiconductor package of a single in-line type including a semiconductor chip, a package body for accommodating the semiconductor chip and a plurality of leads held by the package body to extend substantially perpendicularly to a bottom edge surface of the package body. The package body carries a cutout part at a predetermined position of a side edge that surrounds the package body such that the cutout part is adapted for engagement with a support leg for supporting the package body substantially upright on a substrate.
