  • Publication number: 20070155029
    Abstract: Improved methods and apparatus are provided for the handling and testing of semiconductor devices. One embodiment comprises a die carrier for one or more semiconductor dice having very fine pitch electrical I/O (input/output) elements. The semiconductor dice are temporarily attached to the die carrier in singulated form to enable testing the dice with conventional contact technology. The die carrier may include a flex circuit base substrate and a rigid support frame. Further embodiments comprise materials and methods for attaching the semiconductor dice to the die carrier and for providing a temporary electrical connection with the semiconductor dice during testing. Exemplary materials for providing the temporary electrical connection may comprise a conductive film or tape, a conductive or conductor-filled epoxy, resin or RTV adhesive-based materials, a water-soluble material impregnated with a conductive filler or non-reflowed solder paste.

  • Publication number: 20060284631
    Abstract: A test socket, a test system and methods of testing an image sensor or other optically interactive device. The test system may include a light source for illuminating the image sensor device. A diffuser may be provided to scatter the light. A test socket may include an area configured for receiving the image sensor device. The image sensor device may be in electrical communication with a printed circuit board. The diffuser may be positioned within the test socket or affixed to the printed circuit board. Optionally, the diffuser may provide support for the image sensor device, or a seat of at least partially optically clear material may provide support for the image sensor device. In another embodiment, a test socket includes a seat of at least partially optically clear material enabling collimated light or diffused light to reach the image sensor device.
