  • Patent number: 10410760
    Abstract: A rigid-flex assembly (RFA) includes a circuit board attachable to a focal plane sensor. The RFA includes a flexible wiring section electrically coupled at opposing ends to the circuit board and to an edge connector. The flexible wiring section has a controlled separation distance or volume or vacuum gap between wiring strips for reduction of dielectric electrical loss and electrical cross talk. The flexible section has wires or traces configured to reduce the amount of copper used while optimizing signal integrity. Rigid substrates electrically couple the flexible wiring section to the connector. The RFA uses an end-launch, in-plane connection to the sensor for improved performance. A sensor module includes a housing and a sensor. An RFA is coupled to the sensor for high-speed data transfer and that optimizes signal integrity while providing thermal isolation via the flexible section.

  • Patent number: 9708181
    Abstract: A sealed package having a device disposed on a wafer structure and a lid structure boned to the device wafer. The device wafer includes: a substrate; a metal ring disposed on a surface portion of substrate around the device and a bonding material disposed on the metal ring. The metal ring extends laterally beyond at least one of an inner and outer edge of the bonding material. A first layer of the metal ring includes a stress relief buffer layer having a higher ductility than that of the surface portion of the substrate and a width greater than the width of the bonding material. The metal ring extends laterally beyond at least one of the inner and outer edges of the bonding material. The stress relief buffer layer has a coefficient of thermal expansion greater than the coefficient of expansion of the surface portion of the substrate and less than the coefficient of expansion of the bonding material.

  • Patent number: 9323130
    Abstract: A shutter assembly comprising a first planar member and a second planar member opposed from one another and forming a sleeve having a cavity therebetween, the sleeve having a pair of side rails adjacent the cavity along sides of the sleeve. A first shutter member having a first end is disposed in the cavity and slidingly disposed along one of the side rails, and a second shutter member having a second end is disposed in the cavity and slidingly disposed along the other side rail. The first end is opposed to the second end and is configured to be selectively advanced towards, and retracted from, the second end so as to define an aperture therebetween having a first shape when disposed in a first position, and wherein the aperture has a second larger shape when the first end is disposed in a second position. The first shutter member and the second shutter member maintain a thermal contact with the side rails and the planar members in all positions.
