  • Patent number: 7501660
    Abstract: A housing is specified for an electronic component having at least two connecting parts (4a, 4b), which are partially in contact with the housing. The conductivity of at least subareas of the housing are set in a defined manner and current paths through the housing are formed between the connecting parts. The housing thus has a defined resistance (2), which is connected in parallel with an electronic component (1), and provides ESD protection for the component (1).

  • Publication number: 20080251900
    Abstract: Disclosed is a leadframe for at least one electronic component, comprising at least two electrical lead elements, each of which comprises at least one electrical lead tab and at least one retention tab. Provided between the at least one retention tab and the lead element is a score defining a parallel offset between the retention tab and the adjacent region of lead element. An additional parallel offset is defined between the lead element and the electrical lead tab, such that the retention tab and the electrical lead tab are located in a common plane. The score enables the retention tab to be removed easily without the need for a disadvantageous punched gap between the lead element and the retention tab.

  • Patent number: 7427806
    Abstract: Disclosed is a radiation emitting and/or receiving semiconductor component comprising at least one radiation emitting and/or receiving semiconductor chip (1), which is disposed in a recess (2) of a housing base body (3) and is there encapsulated with an encapsulant (4) that is readily transparent to electromagnetic radiation emitted and/or received by the semiconductor chip (1). The recess (2) comprises a chip well (21) in which the semiconductor chip (1) is secured, and a trench (22) that runs at least partway around the chip well (21) inside the recess (2), such that between the chip well (21) and the trench (22) the housing base body (3) comprises a wall (23) whose apex, viewed from a bottom face of the chip well (21), lies below the level of the surface of the housing base body (3) from which the recess (2) leads into the housing base body (3), and the encapsulant (4) extends outward from the chip well (21) over the wall into the trench (22). A corresponding housing base body is also disclosed.

  • Publication number: 20080012033
    Abstract: An optoelectronic semiconductor component comprising at least one radiation emitting semiconductor chip disposed in a recess of a housing base body, wherein the recess is bounded laterally by a wall surrounding the semiconductor chip and is at least partially filled with an encapsulant that covers the semiconductor chip and is well transparent to an electromagnetic radiation emitted by the semiconductor chip An inner side of the wall, bounding the recess, is configured such that, as viewed looking down on the front side of the semiconductor component, a subarea of the inner side is formed which extends ring-like all the way around the semiconductor chip and which is in shadow as viewed from the radiation emitting semiconductor chip and which is at least partially covered by encapsulant all the way around the semiconductor chip. A housing base body for such a semiconductor component is also specified.

  • Patent number: 7271425
    Abstract: The invention relates to an optoelectronic component containing an optoelectronic chip (1) and containing a chip carrier (2) that has a central region (3) on which the chip is fixed and that comprises terminals (41, 42, 43, 44) extending outwardly from the central region of the chip carrier (2) to the outside, wherein the chip and portions of the chip carrier are enveloped by a body (5) and wherein the projection of the body and that of each of the longitudinal axes of the terminals onto the contact plane between the chip and the chip carrier are substantially point-symmetrical with respect to the central point of the chip. The invention further relates to an arrangement comprising said component. The advantage of the symmetrical configuration of the component is that the risk of thermomechanically induced failures of the component is reduced.

  • Publication number: 20070126098
    Abstract: A surface-mountable light emitting diode structural element in which an optoelectronic chip is attached to a chip carrier part of a lead frame, is described. The lead frame has a connection part disposed at a distance from the chip carrier part, and which is electrically conductively connected with an electrical contact of the optoelectronic chip. The chip carrier part presents a number of external connections for improved conduction of heat away from the chip. The external connections project from a casing and at a distance from each other.

  • Patent number: 7193299
    Abstract: A leadframe for a surface-mountable radiation-emitting component, preferably a light-emitting diode component, having at least one chip connection region and at least one external connection strip. The leadframe is formed in planar fashion and a deformation element, preferably a spring element, is arranged between the chip connection region and the external connection strip. The deformation element enables an elastic or plastic deformation of the leadframe in the plane of the leadframe. A housing, a surface-mountable component and an arrangement having a plurality of such components are furthermore specified.
