    Abstract: Systems and methods in accordance with embodiments of the invention actively align a representative optic array with an imager array, and subsequently passively align constituent optic arrays with constituent imager arrays based on data from the active alignment. In one embodiment, a method of aligning a plurality of lens stack arrays with a corresponding plurality of sensors includes: aligning a first lens stack array relative to a first sensor, varying the spatial relationship between the first lens stack array and the first sensor; capturing images of a known target using the arrangement at different spatial relationships between the first lens stack array and the first sensor; scoring the quality of the captured images; and aligning at least a second lens stack array relative to at least a second sensor, based on the scored images and the corresponding spatial relationships by which the scored images were obtained.

  • Patent number: 9638884
    Abstract: A method of selectively bonding a component to a substrate prevents glue displacement onto neighboring components. The method entails shortening a section of the perimeter of a mount wall so that the foot of the mount wall contacts the glue without causing substantial displacement. A cure step hardens and holds the shortened foot of the mount wall in a stationary position, while providing a partial bond. Meanwhile the rest of the mount wall that is not located near contact pads on the substrate has a tall foot that extends to the surface of the substrate and is bonded in the usual way. By modifying the component, it is not necessary to modify either the chemistry of the epoxy or the epoxy dispense operation.
