  • Publication number: 20090236712
    Abstract: An IC package having reduced thickness includes a lead frame, a chip, and a plurality of bonding wires. The lead frame includes a front side, a rear side, a plurality of pins located on the front side, and a hollow portion formed on the lead frame. The chip is larger than the rear side of the lead frame. The chip includes a plurality of electrodes and is adhered to the rear side of the lead frame. The electrodes correspond to the hollow portion. The bonding wires pass through the hollow portion to be connected with the pins and the electrodes. Accordingly, the IC package can effectively take good use of the space below the lead frame, reducing the height of the bonding wires and saving the packaging space above the lead frame, and reduce the thickness of the IC package without addition of the cost and equipment.

  • Publication number: 20090078838
    Abstract: An annular fan-shaped retractable honeycomb furniture assembly includes a honeycomb core and two panels. A binder is attached to a lateral side of the honeycomb core to serve as a center point when the honeycomb core is developed into an annular shape, and has the effect of fixing and shaping. A slant or an arced surface is formed on an upper side of the honeycomb core adjacent to the binder. The panels are respectively adhered to two opposite external surfaces of the honeycomb core to sandwich the honeycomb core. Each of the panels has one side portion, which projects over an edge of the honeycomb core and is formed with a slot. A fastener tape may be provided to fix the panels together after the honeycomb core is developed or retracted.
