  • Patent number: 5486980
    Abstract: Heat sink apparatus for cooling large electronic devices is formed with a heat sink body having a plurality of pins extending outwardly from the base of the heat sink body and a rotary fan having a blowing surface mounted adjacent the outer extremity of the pins. The pins are separated by intersecting grooves providing a large surface area for the heat sink body. The surface area of the heat sink body is sufficiently large to provide a thermal impedance of substantially less than 1.0.degree. C./W and the volume occupied by the heat sink is sufficiently small to provide a volume performance value of less than about 6.degree. C. in.sup.3 /W.

  • Patent number: 5428897
    Abstract: A mounting spring clamp for securing a heat sink to a device package is secured to the heat sink by positioning the central body portion of the spring clamp in an attachment clip. The clip is compressed and positioned in a groove of the heat sink. The clip comprises a semi-circular shaped seat with ears extending from both sides of the seat and is made from a flexible material. Compression of the ears reduces the seat diameter, thereby trapping the spring's central body, and also creates spring force in the ears, thereby trapping the clip between the fins of the heat sink. The mounting spring has an elongated body with ends extending from the axis of its central body. The ends may be trapped or hooked in appropriate receivers on a frame or socket holding an electronic device package to secure the heat sink adjacent the device package.

  • Patent number: 5422789
    Abstract: A sheet metal device for mounting a component on a circuit board is formed by stamping to defining a head portion and a base portion. The head portion is formed for insertion into a slot in a component such as a heat sink and the base portion is formed for insertion into a printed circuit board. The head portion has spade-form members which engage the walls of the slot and retain the head portion in the slot. The component is mounted on a printed circuit board by inserting the base portion into an aperture in the printed circuit board and soldering the base portion to the reverse surface of the board.

  • Patent number: 4961125
    Abstract: Disclosed are apparatus and methods for attaching an electronic device package and a heat sink to a circuit board or the like. The electronic device package has a body with a planar bottom and leads extending from the body. The distal ends of the leads are coplanar with the bottom of the electronic device package. The heat sink has a base, heat-dissipating fins or the like and a clip for securing the electronic device package to the heat sink. A pair of dimples project downward from the base of the heat sink to tilt the bottom of the electronic device package. Tilting the electronic device package causes the ends of the leads to contact the circuit board so that the leads can be easily soldered to the circuit board. The dimples and the front edge of the heat sink can also be soldered to the circuit board.

  • Patent number: 4446504
    Abstract: Disclosed is means for mounting semiconductor device cases on mounting substrates such as circuit boards. The mounting means includes studs passing transversely through the body of the mounting means for mounting a semiconductor case or semiconductor case and heat sink on one side of the body. The opposite ends of the studs are coated with a solder-promoting material so that the studs may be soldered directly to the circuit board. The body may include electrically conductive pin receptacles for mating with pins extending from the semiconductor case. The pin receptacles have solderable shanks extending from the opposite side of the socket body. Stand-off bosses are also disclosed for spacing the mounting body from the surface of the circuit board and for spacing the heat sink from the surface of the mounting body.

  • Patent number: 4147276
    Abstract: Means for hinging or removably attaching a cover to a chassis comprising a retainer device including a pair of arms spring-urged away from one another. The retainer device is fixed to the chassis with the ends of the arms extending outward into openings in the cover. The arms can be manually pinched to disengage them from the cover openings to thereby permit the cover to be removed from the chassis. Utilization of a pair of retainer devices on the chassis enables one of the devices to be disengaged while the other remains engaged to thus hinge the cover relative to the chassis.
