  • Patent number: 11949997
    Abstract: A device include a first camera, a second camera, and a shutter assembly. The shutter assembly includes a switch, a link coupled to the switch and having a first cover, and an arm coupled to the link and having a second cover. Actuating the switch to a first position disposes the first cover within a first field of view of the first camera and the second cover within a second field of view of the second camera. Actuating the switch to a second position disposes the first cover outside of the first field of view and the second cover outside of the second field of view.

  • Patent number: 7692307
    Abstract: A compliant structure for an electronic device comprises a substrate (110) composed of a first material (111) and a compliant zone (120) within the substrate. A plurality of solder joints (280) are located between, and form a connection between, the substrate and the electronic device (290). The compliant zone reduces the degree of deformation experienced by the solder joints due to thermal mismatch loading between the substrate and the die during attachment of the die to the substrate (chip attach). This reduction in solder joint deformation reduces the likelihood that the solder joints will crack.

  • Publication number: 20070231952
    Abstract: Method of forming a microelectronic package using control of die and substrate differential expansions. The method includes: providing a die-substrate combination including a substrate, a die disposed on the substrate, and plurality of solder paste disposed between the die and the substrate; reflowing the solder paste by exposing the die-substrate combination to temperatures changes including heating the die-substrate combination to liquefy the solder paste, and cooling down the die-substrate combination until the solder paste has solidified to form solder joints to yield the package; and controlling an expansion of the die and the substrate at least during cooling down to mitigate a relative difference in volumetric strain between the die and the substrate. Controlling may comprise exposing the die-substrate combination to pressure changes at least during cooling down.
