    Abstract: A semiconductor package structure includes a bowl-like carrier, a semiconductor component, and electrode pins. The semiconductor component is disposed on the bowl-like carrier and is received in an accommodating recess of the bowl-like carrier. The electrode pins are electrically connected with the semiconductor component through wires. Channels are recessed along recess-walls of the accommodating recess and located between the semiconductor component and the electrode pins, where the wires pass through the channels. Therefore, the length of bonding wires can be reduced, and as well the cost of the wires, let alone the wires can be protected appropriately.

  • Patent number: 8148739
    Abstract: An LED package structure includes a heatsink slug, a positive-electrode frame, a negative-electrode frame, and an LED module electrically connected with the positive-electrode frame and the negative-electrode frame. The LED module includes a plurality of LED chips. The heatsink slug is provided, at its surface, with a plurality of cup-like recesses. The plural LED chips are each bonded, correspondingly, on a plane in the cup-like recess. Each of the LED chips is covered with a fluorescent colloidal layer having a curved and convex contour. As a result, a specific proportion for the color lights emitted from all the LED chips and from the fluorescent material in every direction of a space can be maintained, and that a better spatial color uniformity can be achieved.

  • Publication number: 20110199749
    Abstract: An LED support's lead frame structure includes a side frame, a loading piece connected with the side frame, and at least one electrode pin. The electrode pin is located at one side of the loading piece and is spaced apart therefrom. The loading piece has a thickness same as that of the electrode pin. The electrode pin includes, connected in sequence, a first external leading section, a wire-bonding section, and a second external leading section. Both the first and the second external leading sections are connected with the side frame. The wire-bonding section includes a first protrusion. Therefore, the material required for wire-bonding is decreased, and the steps for machining the lead frame are decreased, so that the manufacturing process can be speeded up. This will help LED products miniaturized and the LED structure superior in thermal conductivity.
